[PHP] Mail sending from nobody to nobody...
For some reason mail is being sent from nobody to nobody every time. I have tried hardcoding the sendmail path, which is the default anyway, and it still doesn't work?

[PHP] Passing array as subject to preg_replace has odd behaviour with limit
Hi everybody, I'm sure this has been mentioned hundreds of times before, but why is preg_replace apparently ignoreing my limit when I pass it an array of text to work on (with just one string each for pattern and replacement)? Is it only obeying per element of the subject? If so, is there a way to correct this unwanted behaviour, maybe through setting a constant or something?

Re: [PHP] Mail sending from nobody to nobody...
Try getting rid of the stripslashes, or if you need to remove them, add an
additional \n to the message after the strip slashes, like so:
if(mail([EMAIL PROTECTED],Added To Mailing
List,stripslashes($message).\n,$from) == false) die('failed');
Also, see http://www.php.net/manual/en/function.mail.php if you haven't
checked there yet. There are some good examples.

Re: [PHP] Extension problem
In other words you could say that if youd like the HTML files to be parsed as PHP files you would need to change the mapping on the server, eg. AddType application/x-httpd-php .php AddType application/x-httpd-php .html the second line would tell apache to run html files as php files. You could also, to do some sneaky things do this : AddType application/x-httpd-php .png or AddType application/x-httpd-php .myDocumentType Url . http://www.mydomain.com/index.myDopcumentType This can usually also be done in the .htaccess file, you need some googling for this as I dont recall the syntax.

It's apache that runs the php script it must some how know that this is a script file.. and the way you tell the apache to run the script is by the extention (.php) since .html is not an serverside script, apache dont nead to run that before sending it. but you can declare that in apache.conf (if you want html files to use php code) :) Enrico Comini [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I use php without problem, but my file is processed by php only if the extension is .php , why ?

[PHP] Re: Weird variable issue encountered... help needed!
My first thought is that some dynamic code on this page has an error. Typical like this : input type=var value=?=$var?' ^^ Or maby a quote is missing? Looking at your examples it looks like there are different parts of the HTML code comming into your var, which would typically be the case with broken quotes. On the other hand it looked like there was a session ID aswell in there, but mainly I would run my code through the W3 validator just to double check. You could also, just in case check that the get_magic_quotes_gpc hasnt changed. There could also be some quotes in some variables messing up your code again. Going from magic_quotes to no_magic can be annoying - I did that experience with my database application some weeks ago...

Guys, second thought. mktime builds a unix time stamp (since the unix epoch, Jan 1, 1970 [I guess]), the difference are maybe due to time zones, because its the number of seconds since Jan,1 1970.

[PHP] Printer Functions
My question involves sending html to the printer to be printed properly.
Here is my code:
$handle = printer_open('Lexmark Z25-Z35'); printer_start_doc($handle,
test); printer_start_page($handle);
printer_set_option($handle, PRINTER_MODE, 'raw');
printer_set_option($handle, PRINTER_PAPER_FORMAT,
PRINTER_FORMAT_LETTER); $file =
file_get_contents('http://localhost/'.$page.'.php?mid='.$mid);
printer_draw_text($handle, $file, 10, 10);
printer_end_page($handle);
printer_end_doc($handle);
printer_close($handle);
When this code runs, a page prints .. However all that prints is the
html source, and it only prints one line across the top of the page and
nothing else. How does one send html to the printer and have the
rendered page print?
I've also tried using printer_write instead of printer_draw_text, but to
no avail.
As always, any help is greatly appreciated.
Thank you in advance,
Lou

{

The PHP script can then store it as it wishes.

Looking at your examples it looks like there are different parts of the HTML code comming into your var, which would typically be the case with broken quotes.

[PHP] PHP 4.3.4, Apache w/ mod_ssl Compile Help
Hi Folks ... A small problem here ... I just rebuilt Apache 1.3.29 with mod_ssl. When doing apachectl startssl I get: [Mon Apr 5 12:19:53 2004] [warn] Loaded DSO libexec/libphp4.so uses plain Apache 1.3 API, this module might crash under EAPI! (please recompile it with -DEAPI) I read through many postings on this topic and the opinion seemed to be that rebuilding PHP with CFLAGS=-DEAPI would fix this, as would simply rebuilding it after Apache as the rebuild should pick up the new APXS file which would define this symbol. After rebuilding Apache with modssl as follows: ./configure --enable-module=so --enable-module=ssl make make install I ran from the PHP directory: make clean make make install If I then do an apachectl stop followed by apachectl startssl I get the error again. I have verified that the new libphp4.so is installed in /usr/local/apache/libexec, and that /usr/local/apache/bin contains the latest apxs file, and that the PHP configuration line points to that file. I have tried the PHP rebuild both before and after setting CFLAGS=- DEAPI in my local shell environment (with export). The results are the same -- the error shown above. What am I missing?

I have a database that is storing all of my records. One column is of type enum where the two legal values currently are home and work; work is default. I'm building a PHP object that will be my interface to the DB. In the object I have a variable called $EmailType which will hold the value of the database column. I wrote some set and get methods to work with the variable and am now asking myself: What should I do if someone tries to set $EmailType to a value that is not listed in the enum set?

[PHP] PHP Access Violation using PEAR::Mail_smtp
I'm getting the following error when using the Mail_smtp package from PEAR:
PHP has encountered an Access Violation at 0177A8B4
It does not occur everytime I use it, but even when send() returns true,
e-mail messages are not being sent. However, it all worked fine a week
ago when I was testing it, and I don't think anything has changed to my
installation of PHP.
I'm using PHP 5RC1 on a Windows Server 2003. The localhost has no
built-in mail functionality, so I cannot use mail(). I must use
Mail_smtp to log in to the mail server. I also have Net_SMTP and
Net_Socket installed, and, like I said, when I first dropped in my code,
all was working fine.
My code is, as follows:
code
require_once 'Mail/smtp.php';
$smtp_settings = array(
'host' = 'localhost',
'port' = '25',
'auth' = 'LOGIN',
'username' = 'username',
'password' = 'password'
);
$to = [EMAIL PROTECTED];
$msg = Line 1\nLine 2\nLine 3;
$headers = array(
'Subject' = My Subject,
'From' = [EMAIL PROTECTED],
'Date' = date('r'),
'Content-Type' = 'text/plain',
'X-Mailer' = PHP/ . phpversion()
);
$mail = new Mail_smtp($smtp_settings);
if ($mail-send($to, $headers, $msg)) {
echo h2Sent successfully/h2;
} else {
echo h2Not sent/h2;
}
/code
If I don't get the access violation error, I get the message Sent
successfully. Yet, I don't receive any messages.
In the code for Mail_smtp (in Mail/smtp.php), I have added the following
line just under the function declaration line for the send() method:
echo test;
When the access violation occurs, I get this line:
PHP has encountered an Access Violation at 0177A8B4test
From this, it appears to me that the access violation is not occurring

However, I do not know much more about these Access Violoations, other
than PHP is trying to access memory that it doesn't have permission to
access. I couldn't find anything at bugs.php.net or through Google that
helped much with this problem.
Any help would be greatly appreciated. I am on a tight deadline, so any
help ASAP would be even more greatly appreciated. ;-)

[PHP] PEAR Sequences
Greetings,
Has anyone out there transitioned an existing app from using the
mysql_* functions in PHP to PEAR DB?
I'm re-writing an existing PHP application, and I'm required to utilize
PEAR's DB class as the database layer. Currently, the application is
using the mysql_* functions to access the database and the primary
key/identity column is using AUTO_INCREMENT to calculate the id for
each record in several tables.
I realize that PEAR doesn't provide direct access to the last insert id
(like I could get with mysql_insert_id()), and instead utilizes the
sequences facility to emulate AUTO_INCREMENT (I'm assuming this is to
provide similar functionality to some engines that don't have
AUTO_INCREMENT). So, I need to have a seamless way to transition from
using the AUTO_INCREMENT.
In experimenting, I've seen that when creating a sequence, PEAR DB
creates a table named {$sequence_name}_seq and that table contains a
single record with a single column that contains the last used sequence
id.
So, let's assume I have a table called item_master, and I'm going to
utilize a sequence I'm going to name item_master as well. Normally PEAR
would create an item_master_seq table and keep track of the unique ID
in that table. When I implement the new code, can I just create a
item_master_seq table in the production database with the appropriate
characteristics, update the record in that table to the next available
id for the item_master table, and then turn off AUTO_INCREMENT on the
table? In experimenting, this appears to be the case, but since I'm
going to updating a production application, but I want to be absolutely
sure this isn't going to cause any unforseen problems before I do this.
Thanks in advance,
Jeremy

I am going to create a select box, but am still trying to write enough tests to catch myself if I try to do something foolish. The in theory part is what I'm trying to check for. :-) I questions is, if someone tries to set the var to an invalid type should I throw a warning, or die or do nothing and just use the default or previous value. I'm inclined to stay away from the last option cause it invites strangeness to people who might be new to the system. As long as register_globals is set to off what come in from your select box should be used as the value of the enum field. It is always best to do as much data validation as you feel is worth it. IMO, in the case of using a select box to set the values of an enum MYSQL field, (unless this application is for something that is really security conscience, like banking or something), I feel I can usually trust the select field. Remember that if someone tries to set the enum filed to something other than what is specified, an empty string will be stored. Therefore, when you are reading from the database you could always check for that, too. -- Jason Giangrande [EMAIL PROTECTED] http://www.giangrande.org http://www.dogsiview.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Printer Functions
Do you have the option of printing through Word or something similar?
We had the same problem and ended up saving the file to a cache and
using COM objects to print to the default printer through Word.
The code looks a bit like this... Of course, it expects you to define
the $saveFile as the file it's trying to open.
?
// initialize the word components
$word = new COM(word.application) or die(Unable to instantiate
Word);
print Loaded word version ($word-Version)\n;
$word-visible = true;
$word-Documents-Add();
// open the file
$word-Documents-Open($saveFile);
// output the file to the default printer
$word-ActiveDocument-PrintOut(1);
// shutdown word
$word-Quit();
?

Subject: [PHP] Printer Functions
My question involves sending html to the printer to be printed properly.
Here is my code:
$handle = printer_open('Lexmark Z25-Z35'); printer_start_doc($handle,
test); printer_start_page($handle);
printer_set_option($handle, PRINTER_MODE, 'raw');
printer_set_option($handle, PRINTER_PAPER_FORMAT,
PRINTER_FORMAT_LETTER); $file =
file_get_contents('http://localhost/'.$page.'.php?mid='.$mid);
printer_draw_text($handle, $file, 10, 10);
printer_end_page($handle);
printer_end_doc($handle);
printer_close($handle);
When this code runs, a page prints .. However all that prints is the
html source, and it only prints one line across the top of the page and
nothing else. How does one send html to the printer and have the
rendered page print?
I've also tried using printer_write instead of printer_draw_text, but to
no avail.
As always, any help is greatly appreciated.
Thank you in advance,
Lou

Re: [PHP] Question, what to do when finding an error while validating data
From: Mike Zornek [EMAIL PROTECTED] I'm making a conscience effort to improve my PHP skills, that being making objects, unit testing, better error handling etc. So I have a questions. I have a database that is storing all of my records. One column is of type enum where the two legal values currently are home and work; work is default. I'm building a PHP object that will be my interface to the DB. In the object I have a variable called $EmailType which will hold the value of the database column. I wrote some set and get methods to work with the variable and am now asking myself: What should I do if someone tries to set $EmailType to a value that is not listed in the enum set? Either throw an error and stop the whole action from completing, or just silently ignore it and give it the default value. I would go with the second action, personally. If you're giving the user a clear way of choosing home or work, like radio buttons or a dropdown and you receive another value, someone is trying to pull something. I'd log the error somewhere for future analysis and then just give them the default. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This problem only seems to be happening on one of the virtual hosts on
this
system, and I cannot seem to figure out just what it is.
I have a simple form posting to search.php, with a text input field, with
a
name of 'search'. And since this site is an internal site, register
globals
are on, as we are not worried about anyone misuing any of the variables in
use.
In any even, this problem was noticed about a week ago, and it did not
exist
before.
After inputting some text into the search box, in this example, 'var',
sans
quotes, and i hit submit... on the next page, I am just having it return
just $search for testing, and, it comes back sporadically with: 'var', but
most of the time, it comes back with:
var^!#ndda/form
or
var4194092d098240928d12ed
or
var#c0c0c0
or
varput type=text
etc. etc. it seems soemthing is somehow corrupting the variables, and I
cannot seem to figure out what it might be. This has been working fine
until
about the past week, and I cannot think of any major changes that may have
happened within the past week that could have caused this... and as I
mentioned above, it only seems to be this one virtual host. And ai also
compared with backups of all of y included files at the beginnings and
ends
of each script from before this problem started happening, and I can see
no
major changes in any of them. And, this is happening around all php
scripts
on the site...
I am running 4.3.4, with apache 2, FreeBSD 4.8, and the data is all stored
on a vinum partition. The server has been rebooted, a fresh install of
php... tried setting output buffering on and flushing it at the end of the
script(s), however, they seem to get hacked up when doing that, so I stay
away from that band-aid fix...I am using sessions as well, as a few
scripts
within the site store session variables... and also using SMBAuth to do
authentication from our domain controller...
I've been pulling out my hair for 4 days straight on this issue, and I am
all out of ideas, any help would be *GREATLY* appreciated!

[PHP] Re: session_exist() ?? Can this be done?
Thanks, Aaron, I tried this method and it appears to work just fine. Here's
a simplified version of what I'm doing:
if (isset($_COOKIE[session_name()])) {
session_start();
if ($_SESSION['loggedin'] 'yea_baby';
session_destroy();
$_SESSION = array();
// Return to log-in page to re-authenticate.
header(Location:/login.php);
}
So, this allows me to check to see if a session exists without having to
first start the session. If the cookie is found, then the session is started
and verified by checking a value. If the session value isn't there, then I
destroy the session, clear out the $_SESSION vars and send back to log-in
pgae. This only works if you are restricting passing sessions IDs via a
cookie, which I am doing to make my sessions a bit more secure.

I've been doing exactly that, it works great. I use,
$sessid = $_COOKIE[PHPSESSID];
if ( isset($sessid) ) {
session_start();
}
I use 'if( isset($sessid) )' in the rest of the code if there are things
that should only be done if there is a session. Only my login
authentication page starts the session if there isn't a cookie. Of course,
for security you ought to verify the session after starting it, and unset
$sessid (and destroy_session() ) if something screwy is going on.
The reason I set things up like this is so that users are not bothered with
cookies unless they need to be. I use cookies for the administration side
of the site, but casual users don't need a session, so why should they have
a cookie? -- I'm a not a proponent of passing around useless data :).

Hi,
just on a side-note, the session is not always kept in a cookie ( if
cookies are deactivated the session is saved in the _GET or _POST variables.
A check for $_REQUEST[session_name()] might help you some more but can
be exploited quite fast
eg: index.php?SID=foo
I guess the best way to solve your problem would be to set a _SESSION
variable on creation and check for it's presence
if ( isset ( $_SESSION['session_activ'] )
AND $_SESSION['session_activ'] === TRUE ) {
// session runnning
} else {
// no session running
}

Again,
as a sidenote, this is the first example of the PHP session documentation:
[ quote - http://de.php.net/session ]
?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
$_SESSION['count'] = 0;
} else {
$_SESSION['count']++;
}
?
[ /quote ]
When using exactly this script you could check wether $_SESSION['count']
equals 0 to make sure the session was just created.

[PHP] Reusing MySQL Connections - Can it be done?
I am trying to use fewer resources and processes when making database
connections in my scripts, so, upon the first call to make a DB connection,
I store the Link Resource ID in a constant variable that can be accessed by
all other functions that need a DB connection, like this...
function connect_db() {
if (!defined('_CONNECT_DB')) {
$result = @mysql_pconnect(localhost, Username, Password);
@mysql_select_db(database_name);
define('_CONNECT_DB', $result);
}
return _CONNECT_DB;
I call this function this way...
$query = SELECT * FROM table;
$connid = connect_db();
$result = mysql_query($query, $connid);
What's odd is that this works for the first query, but after that the
Resource Link ID stored in _CONNECT_DB ceases to work, making MySQL issue
the error: mysql_query(): 4 is not a valid MySQL-Link resource...
Is there any reason why this isn't working? Normally I store the Resource
Link ID in a local variable that I can re-use with no problem, so, I can't
understand why storing the Resource Link ID in a constant var won't work? Is
it not possible to re-use the same connection for multiple queries to
different tables in the DB? I know I can do this if the Resource Link ID is
assigned to a local var, so, maybe it can't be stored in a constant var??
Only other solution I can think of is to use non-persistent connections and
simply make a connection to the DB then immediately disconnect for each
function that needs DB access, but, I'm wondering if this will create more
overhead and overload the database with too many connections?
I've searched and read just about everything I could find about exactly how
PHP and MySQL work together, but, if there's anything that explains in
detail exactly what is happening when you call mysql_connect or mysql_query,
please point me in its direction.
Any input on this is most appreciated!

Re: [PHP] Bug with multipart/form-data ?
Maybe the post_max_size is also exceeded, and therefore it's handled with sense I think.. Otherwise I'm not sure I think this is handled the right way, if it's only upload_max_filesize that's exceeded. -- // DvDmanDT MSN: dvdmandt¤hotmail.com Mail: dvdmandt¤telia.com John W. Holmes [EMAIL PROTECTED] skrev i meddelandet news:[EMAIL PROTECTED] From: Jay Blanchard [EMAIL PROTECTED] [snip] I have a form in a page 1, that POSTs a file and some hidden's to page 2. If the file size is bigger that the max in php.ini, in page 2, $_POST is empty. [/snip] Why, of course it is! The php.ini sets the max file size $_POST will be empty because it would not be allowed to load. You have two choices; A. increase the max file size in the php.ini 2. reduce the size of the file being uploaded. It is not a bug. I understand what you're saying, and maybe the OP will agree with me here, but does that seem like the natural way for it to be handled? Shouldn't $_FILES be empty and $_POST still have the rest of the posted data? PHP decides to reject the file, but why does it reject the rest of the post data, also? Maybe off-topic for this list, but if that's what the OP was talking about, then I've got to kind of agree with him. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: session_exist() ?? Can this be done?
Hi Red... Actually, I have my site set to only use cookies for storing
session ids to make it more secure and so that session ids aren't passed via
the URL. Only problem with checking for existence of a session using your
method is that you have to first start the session, which is what I'm trying
to avoid. I only want to create a session for a user that I know has already
been authenticated first, which for my site seems to be the existence of the
session cookie.
Monty
just on a side-note, the session is not always kept in a cookie ( if
cookies are deactivated the session is saved in the _GET or _POST variables.
A check for $_REQUEST[session_name()] might help you some more but can
be exploited quite fast
eg: index.php?SID=foo
I guess the best way to solve your problem would be to set a _SESSION
variable on creation and check for it's presence
if ( isset ( $_SESSION['session_activ'] )
AND $_SESSION['session_activ'] === TRUE ) {
// session runnning
} else {
// no session running
}
-- red
[...]
Thanks, Aaron, I tried this method and it appears to work just fine. Here's
a simplified version of what I'm doing:
if (isset($_COOKIE[session_name()])) {
session_start();
if ($_SESSION['loggedin'] 'yea_baby';
session_destroy();
$_SESSION = array();
// Return to log-in page to re-authenticate.
header(Location:/login.php);
}

A define is pretty much for strings only, not objects or resources. Try
using $GLOBALS['_CONNECT_DB'] instead.

It appears you can't pass constant vars by reference, or am I missing your

suggest I need to use it. I tried define('_CONNECT_DB', $result); and
return _CONNECT_DB; separately, but neither worked.

[PHP] Code Review PLEASE !!!
Hi,
I am a newbie PHP programmer, I have some code that works but I want some tips on how
I an Improve my code, i.e. should I be doing my updates / deletes on same php page as

correctly am I handling form data as efficient as possible?

Re: [PHP] Code Review PLEASE !!!
Wells first of all, you are going to want better form input validation.
For Example:
foreach ($_POST['fleet_id'] as $key = $value) {
$fleetCode = $_POST['fleet_code'][$key];
$historyUrl = $_POST['history_url'][$key];
$downloadUrl = $_POST['download_url'][$key];
mysql_query(UPDATE imp_fleet SET fleet_code = '$fleetCode', history_url =
'$historyUrl', download_url = '$downloadUrl' WHERE fleet_id = $value) or die
(mysql_error());
}
Are you sure that $_POST['fleet_id'] is valid? or even a number?
What happens with $_POST['fleet_id'] == '1 = 1'?? Well, long story
short, imp_fleet has no more records.
Just a simple example of a huge problem.

Re: [PHP] Code Review PLEASE !!!
If it were me I would do both Client and Server side validation.
The majority of the time the client side will suffice, but, simply put,
because you don't/may not look at the HTML source of a web page, doesn't
mean that nobody else does.
The fact of the matter is, you should not trust any data that comes from
a form. Even if the ids come from the database, you still want to
ensure that they really are a valid numerical value or whatever your ids
happen to be based upon.

cookies are deactivated the session is saved in the _GET or _POST variables.
A check for $_REQUEST[session_name()] might help you some more but can
be exploited quite fast
eg: index.php?SID=foo
I guess the best way to solve your problem would be to set a _SESSION
variable on creation and check for it's presence
if ( isset ( $_SESSION['session_activ'] )
AND $_SESSION['session_activ'] === TRUE ) {
// session runnning
} else {
// no session running
}

Re: [PHP] Code Review PLEASE !!!
* Thus wrote Matthew Oatham ([EMAIL PROTECTED]):
Hi,
I am a newbie PHP programmer, I have some code that works but I want some tips on
how I an Improve my code, i.e. should I be doing my updates / deletes on same php
page as the display page, am I using transactions correctly, am I capturing SQL
errors correctly am I handling form data as efficient as possible?
?
use full php tags: ?php
if (isset($_POST['delete'])) {
$deleteList = join(', ', $_POST['delete']);
be careful here! if I add to the _POST data something like
delete%5B%5D=%29%20OR%281
then I just deleted all your records.
//Enter info into the database
mysql_query(begin);
foreach ($_POST['fleet_id'] as $key = $value) {
$fleetCode = $_POST['fleet_code'][$key];
$historyUrl = $_POST['history_url'][$key];
$downloadUrl = $_POST['download_url'][$key];
I would set up your array's so they are a little more readable and
dont rely on autoincrementing array key's. So your loop would look
something like this:
foreach($_POST['fleets'] as $fleet_id = $fleet) {
echo $fleet_id; // the fleet_id
echo $fleet['code'];
echo $fleet['urls']['history'];
echo $fleet['ulrs']['download'];
...
mysql_query(UPDATE imp_fleet SET fleet_code = '$fleetCode', history_url =
'$historyUrl', download_url = '$downloadUrl' WHERE fleet_id = $value) or die
(mysql_error());
escape your data that is untrusted, see http://php.net/mysql_real_escape_string
}
if ($deleteList) {
mysql_query(DELETE FROM imp_fleet WHERE fleet_id IN($deleteList)) or die
(mysql_error());
}
if (mysql_error()) {
this is never reached if there was an error since you die'd() on
errors befor.
}
}
...
while ($row = mysql_fetch_array($sql)) {
?
tr
tdinput type=text name=fleet_code[]
value=?=$row['fleet_code']?input type=hidden name=fleet_id[]
value=?=$row['fleet_id']?/td
tdinput type=text name=download_url[]
value=?=$row['download_url']?/td
tdinput type=text name=history_url[]
value=?=$row['history_url']?/td
tdinput type=checkbox name=delete[] value=?=$row['fleet_id']?/td
// set up a variable for the input form names for easier reading.
$var_name = 'fleets['.$row['fleet_id'].']';
?
td
input name=?php echo $var_name?[code]
input name=?php echo $var_name?[urls][history]
input name=?php echo $var_name?[urls][download]
...
I'd suggest not using the ?= shorthand also.
HTH,
Curt

From: http://www.php.net/manual/en/language.constants.php
Only scalar data (boolean, integer, float and string) can be contained
in constants.

somewhere in the manual it is said that while a resource or link or
some such identifier might look like an integer, it actually isn't.
So by extension it is not a scalar value and thus cannot be stored via
the means of a define().
Use a 'normal' variable instead.

[PHP] mysql_query problem with multi dim arrays
hi... i cant cut and paste my exact mysql query because it takes the '' stuff out doubles the $'s and the ,'s in the whole thing (dont know why but anyways...)... i have a query that goes something like this: mysql_query(insert into $GuestbookTable values(NULL, '$_SESSION[add][date]', '$_SESSION[add][name]', $_SESSION[add][email]..); the problem i get is using the multi dimentional arrays to insert text and stuff all i actually get when i echo the query or do a real insert is: echoed it would be something like: insert into rnjresort.guestbook values(NULL, 'array([add]), 'array([add])', 'array([add])', ... any idea what the problem is here? do i have the '' in the wrong places?? i know that works on single dimention arrays but doubled?

Hi,
only use double quotes () if you want to have variables interpolated e.g.
$myVal = 'its amazing';
$x = wow $myVal;
think out about the way you layout your code - it helps when you
come back to it 12 months later ;-)
sanitize all incoming variables (POST/GET/COOKIE) by changing their type
or performing some other function on them to make them safe.
writing:
(int) $someVar;
means make $someVar an integer; which has the nice side affect of turn
ALL strings into 0 (apart from those beginning with a number in which
case it keeps the numbers but that is quite sane I think)
limit your use of temporary variables e.g: don't create $action if you
are only going to use it on the next line - its a performance hit and
looks unelegant - a good place for temp vars is to increase readability
in your code, more often than not, I feel, readability is king.
DO:
if ($_POST['action'] == 'update') {
NOT:
$action = $_POST['action'];
if ($action == 'update') {
DO:
$action = perform_check_on_var( $_POST['action'],
array($arg1, $arg3),
$arg2 );
if ($action == 'update') {
speaking of readability -
comment you code; especially the bit the make your eyes water! google
around for stuff like phpDoc or phpDocumentor; that will at the very
least give you good tips on what to stuff put in your comments and how
to define them (getting into this habit pays dividends later when
documentation generation come into play - for which tools like
phpDocumentor are written ;-) ... all kinda based on javaDoc (something
to google ;-) as far as I can see.
if you are just starting out and its feasable why not give php5 a go -
its feature complete and quite stable (RC1 currently); alot of the new
features are really quite cool! besides as you learn you will not have
to step over to a new version (which in itself can be a learning
experience!).
BTW: there is nothing wrong with having one page handle all
updates/deletes etc - although becareful of filesize, longfile are a
pain to edit/maintain - in such case you maybe want to create functions
of the update and delete code and call them from your main script.
At the end of the day its a matter of preference and application design
choices which lead to one or the other scenario. try googling for 'Model
View Controller PHP' - hopefully you'll get some useful code/examples of
request processing control which uses single entry points (i.e. a single
page) to perform all actions.
lastly I made a few slight alterations to your example script:
?
include ('./db.php');
if ($_POST['action'] == 'update') {
//Enter info into the database
mysql_query(begin);
if (isset($_POST['delete']) @count($_POST['delete'])) {
foreach ($_POST['delete'] as $k = $val) {
(int) $_POST['delete'][ $k ];
if (! $_POST['delete'][ $k ]) {
unset($_POST['delete']);
}
}
if ($deleteList = join(', ', $_POST['delete'])) {
mysql_query(DELETE FROM imp_fleet
WHERE fleet_id IN($deleteList))
or die (mysql_error());
}
} else {
foreach ($_POST['fleet_id'] as $k = $val) {
$fleetCode = (int) $_POST['fleet_code'][ $k ];
if (! $fleetcode) { continue; }
$historyUrl = str_replace(', '',
$_POST['history_url'][ $k ]);
$downloadUrl = str_replace(', '',
$_POST['download_url'][ $k ]);
mysql_query(UPDATE imp_fleet SET
fleet_code = '$fleetCode', history_url = '$historyUrl',
download_url = '$downloadUrl'
WHERE fleet_id = $val)
or die (mysql_error());
}
if (mysql_error()) {
echo (There has been an error with your edit / delete request.
Please contact the webmaster);
mysql_query('rollback');
} else {
mysql_query('commit');
}
}
?

Well, then again you can still write your query as:
$sql = INSERT INTO table (field1, field2, ..., fieldn)
$sql .= VALUES (' . $ar['index1']['index2'][$i] . ' .
,' . $ar['index1']['index2'][$i] . ';
or some such ... close/open the strings in between :)
