[PHP] using a counter in a foreach loop
I have a pretty basic question and was wondering if someone could point
me in the right direction:
I have a foreach loop, where I execute some commands for each element in
a certain array. One thing I would like to add to this loop is a
counter, so that on each iteration of the loop I have a next higher
number. The following does not work:
foreach ($months) {
$i = 1;
// do some things
$i++;
}
because in each new iteration of the loop, $i is reset to 1. Is there a
way that I can achieve this effect? Thanks for any advice,

[PHP] OT - number of chars in querystring
Sorry for this quick OT question -- I'm skimming thru the HTTP spec but can't find anything that defines the character limit in GET requests. I'm writing a form that uses GET to send data to my PHP script, but I'm afraid that if the user enters too many characters then some will get cut off. Does anyone know the actual limit?

If that's the case, you should really have your application determine the information to be submitted and then store/create them as hidden values in a form. That way, not only will you have no problems with length, but you don't have to worry about the client caching it. I wanted to use GET rather than POST method so that users could bookmark the results of the form -- it is essentially a search engine for a MySQL database. The form has built-in limits to how long the inputs can be, and in fact most of the inputs are really select listboxes and not text-style inputs, so I'm not really worried about having TOO many characters -- but it could get over 255, which is exactly the number that I thought I had read was a maximum. Thanks for the reply, Darren. 2048 seems like a workable limit to me.

Re: [PHP] Array in a Loop Question
On Tuesday, March 26, 2002, at 01:18 PM, Jeff Hatcher wrote:
I have a form that gets repeated depending on number of members in a
group(1 form surrounds all members). I separate the entries by assigning
a count value to the names of the inputs (Ex. input type=text
name=address$count value=). Does anyone know how I can pull the values
back out of the $_POST[]?
Example of ideal scenario that does not work:
case process1:
for ($i=0;$i$_POST[count];$i++)
{
$_POST[address$i]
}
The initial form:
for ($i = 1; $i = $_POST['count']; $i++) {
print input name=\address{$i}\ type=\text\ /\n;
}
print input name=\count\ type=\hidden\ value=\ .
$_POST['count'] . \ /
What the above loop does is it makes a number of address inputs equal to
$count... if $count is equal to 3, then you will get
input name=address1 type=text /
input name=address2 type=text /
input name=address3 type=text /
input name=count type=hidden value=3 /
I changed your $i from 0 to 1 because it makes it mentally easier to
work with (for me at least).
Now in your next script, which is the target of the form, here is what
you want to have:
for ($i = 1; $i = $_POST['count']; $i++) {
// do some code with $_POST[address{$i}], such as
// entering it into a database or echoing it to the user in HTML
}
Some further notes -- the hidden form field was so that you could give
the second script the count variable, so it knows how many loops to do
(this value is otherwise not available to the second script). Also, the
use of doublequotes in the second script ($_POST[address{$i}]) is
imperative because with singlequotes the variable $i will not expand to
$_POST[address2] or whatever.

You have to jump out of the quoted string that represents your SQL
query when you echo the value of the $_POST variable. Like this:
$sql = SELECT a FROM b WHERE c=' . $_POST['d'] . ';
Note that I 'jumped out' immediately after the singlequote mark (which
you need if your value is going into a string field) by closing the
double-quoted string, using the dot to append the value of the variable
$_POST['d'], and then using a dot to append another double-quoted string
(which contains nothing but a single quote in it).
Sometimes, depending on what your variable names look like, you can just
escape your variable by using braces ('{' and '}'), but I think it's
just easier to use the dot do appending from string to variable value to
string again.

You can pass $_GET variables in this way, which become available on the

http://domain.com/whatever.php?theme=metallic
Now in the whatever.php script, if there is code like this:

if ($_GET['theme']) {
switch $_GET['theme'] {

Obviously, you wouldn't really use a theme in this fashion since you'd
have to replicate this value in every link in your document -- this kind
of thing is more appropriate to have in a session variable. But the
lesson is the same -- variables can be passed in this fashion for any

You should use either single quotes or double quotes in any associative
index. You do not need to use them for numeric indices.
$_SESSION['x_Email']
$_POST['loginName']
$form_html['button']
$count[1]
$item[7]
Don't forget that variables will not expand within single quotes. Use
double quotes if you have a variable in your associative index.
$_POST[filename{$i}]
Again, not really an issue for numeric indices.

Re: [PHP] Multipage form
On Wednesday, March 20, 2002, at 11:57 AM, David Johansen wrote: I was just wondering what was the best way to handle a multipage form. Would the best way be to keep passing the variables through the forms as hidden values or should I use sessions and store all the values as session variables? What's the best way to handle all of this? Also the different forms will all be in the same php file that loops to itself if that makes a difference. Thanks, These can be a pain in the ASS. But as for the answer to your question, it's really more a matter of personal preference and the particular application you have. For instance, if I were writing a shopping cart or some extremely complicated sequence of forms that fork off into a tree-like structure, I'd probably just give up on hidden form fields and use session variables. But because session variables can be tricky to unset (you have to make sure the user explicitly executes a script to unset them), I try to avoid it when I can. I have a linear multi-part form (not one that branches into different directions) where I take user input and throw it all into hidden form fields -- very tedious, yes, but I have finer control over what values get passed around as the user moves on. Side note: the trickiest thing can be getting multiple-listbox values to be passed on, since it'll be hard to put multiple values into a single form field. The way to do it is a miniature loop for each case where you need to do this, that places each value into an element of an array -- then implode the array into a string and put the string into the hidden form field. Explode the string back into an array on the next part of the form. For a branching, tree-like system I'd probably use sessions unless for some reason you can't -- just make sure the user has a way of knowing what's in their cart (or equivalent for your site) somewhere, so that if they closed the window in the middle of filling out the form, possibly expecting it to reset all of their work, then they won't be surprised when they try to fill out the same form later and see all of their old values from their session.

insert
the above values in the tables tblAdddress in columns name, Rank,

There are a couple of ways to do it.
$sql = INSERT INTO tblAddress
VALUES ( . $_POST['name'] . , . $_POST['rank'] . , .
$_POST['age'] . );
mysql_query($sql, $db); // $db is your database connection pointer
That one only works if the first three columns in the table are the ones
you want to insert the values into. The next version is like this:
$sql = INSERT INTO tblAddress (name, rank, age)
VALUES (' . $_POST['name'] . ', ' . $_POST['rank'] . ', ' .
$_POST['age'] . ');
mysql_query($sql, $db); // $db is your database connection pointer
That one works if you don't know the layout of the table, but know the
names of the columns you want -- it's specific, and more portable than
the first way (in case you ever alter your table structure). The last
way to do it is like this:
$sql = INSERT INTO tblAddress
SET name=' . $_POST['name'] . '
rank=' . $_POST['rank'] . '
age=' . $_POST['age'] . ';
mysql_query($sql, $db); // $db is your database connection pointer
In the above examples, I've made the assumption that the form is being
sent via POST and that you are using PHP 4.1.x with register_globals
off, adjust accordingly if this is not the case. Also note that the
singlequotes used to surround each database entry value aren't always
necessary, I think that with INT columns they can be omitted (but are
required for string columns since spaces are tokens in this case [I
think]).

I was wondering about a similar scheme to this -- here's my idea: take all user input, and in addition to running it through error-checking functions, run it through htmlentities() to turn all of its HTML into entities. This prevents any user-input HTML from being created (it becomes literal). Then, running str_replace() for each HTML tag that I -want- to enable. str_replace is faster than any of the regex functions, from what I hear, and if I want to enable just b, i, em, strong, and a tags, it seems like I could just str_replace the entities for these to transform them back to proper tags (i.e. change lt;bgt; back to b). This seems like an efficient way to do it, but is it any faster or better than just using strip_tags() ? When I originally thought of doing it, it seemed like a good way of getting around the fact that user-specified JavaScript attributes are still allowed in strip_tags()-parsed text.

Couldn't you just add another method called return_field_name() to the

given the value of the field name. Your code would look like this:
class obj
{
var $field;
function obj($value)
{
$this-field = $value;
}
function return_field_name()
{
return $this-field;

$o = new obj(field value);
print $o-return_field_name();

Re: [PHP] MySQL and indexes
On Monday, March 18, 2002, at 03:40 PM, Jennifer Downey wrote: Just wondering, does a table have to have an index? If so what should I consider when making a colum an index? You're not required to have an index, as far as I know. It's just that an index is a way of optimizing retrievals to and from the table. Think of an index as a mini-table or meta-table that keeps track of a specific column in your actual table -- the RDBMS prefers to store all of the data in its own order, but the index stores a map of one of those columns according to a more search-friendly order. The rule of thumb with indexes is to use indexes on columns that you search frequently. So, if you rarely do any searches based on pet_hunger, then don't index that. But you might often do lookups for pet_name, so that would be a good one to index. Although you have a petid column, it's VARCHAR and thus I have a feeling it's not a traditional ID column. By that I mean it's not a column with a unique value for each row in the table. If you really want to take advantage of the true power of a RDBMS, you should create a traditional ID column like the following: pet_uniq_id PRIMARY KEY AUTO_INCREMENT NOT NULL which will automatically generate a new unique value each time you add a record. This will help you immeasurably if you ever decide to normalize this table. From what I can tell, your table as is does not appear to be normalized, which means that while it may be functional, you're not making the most of what your RDBMS gives you to work with.

I would store the IP number into four separate columns in a database table, one column for each part of the IP. This is just to be safe, really you only need two (one for the domain and subnet numbers, and the last for the machine number) but if you ever needed to cross subnets then you'd be glad you had set up your data in this flexible way. Use explode(., $ip_input) to split the parts and then insert them into the database. Then just test to see if the machine number is between two given machine numbers and that the domain + subnet numbers are the same as the database domain + subnet numbers.

Runs the while loop at least once, regardless of whether or not the

use this technique for looping through a result array from a
mysql_fetch_*() function if the internal array pointer has already been
bumped to the second position by a containing while loop. Now I just
use two result container variables instead of the same one, since it's

I changed your code slightly (to major if it's your baby). It might
puke if
the $row is empty for the While loop. If it does, try an @ sign before
the
while. I didn't test it but it looks like should go. Or, generate some
interesting error messages.
My experience with programming is limited, but I was under the
understanding that the @ sign should be used only suppress possible
unexpected error messages from users; that using it to suppress known
errors is really not as good a solution as finding out what is causing
the error and fixing it... of course, sometimes in a pinch you have to
MacGuyver the thing I guess. Just some advice :)

A good rule of thumb (IMO) is to make sure that your site works
perfectly and does exactly what it should using HTML/PHP code alone
(test with JS turned off), and then add features with JavaScript that
may make it -better-, but not features that are ever -required-. For
instance, make sure that your PHP validates the forms that are submitted
to the server, but if you have already done this then you can add
JavaScript form validation so that the user doesn't have to wait for a
full resubmit to make sure that they have everything.
There are other ways that I can see JS enhancing a web site, as long as
you don't require JS to do what you want... but in all honesty I haven't
learned much JS so even I don't really take this route. It's just a
theory.

Hm... have you tried using a loop to get their values, rather than using
the numeric indexes? Like this:
foreach ($choice as $array_element) {
echo $array_element;
}
This will go through the entire array, regardless of numeric index, and
echo the value of each element in the array. Try this, if it doesn't
work then perhaps only one value is being passed to the receiving script.
Have you made sure your listbox features the attribute
multiple=yes
and have you made sure to select more than one item in the listbox by
holding down either Alt (PC) or Cmd (Mac) as you make your selections.
If you're only selecting ONE item, then only one item will be passed to
the receiving script.
Use the above techniques to make sure that you are actually passing more
than one value.

It appears that this extension is still fairly experimental, so the way that the program behaves may differ depending on which version you're running. Which version of PHP are you using, for which OS? Did you compile using the --enable-xslt and --with-xslt-sablot configure parameters? Try some of the workarounds suggested in those annotations, specifically the one which suggests that xslt_process() doesn't like NULL arguments. It'll be ugly, but perhaps you can use implode() to read those files into a string, and get it to work by passing string references rather than filenames. If you really want to use filenames, try using an absolute path, try using ./ before the file names (assuming those files are in the same directory as the script itself). Finally, consider passing a joke array as the 5th and 6th arguments to the function. It may be that in your particular build you need to use workarounds.

So that everytime a separate file is saved on to the server, it's info is added to this total file. Is this the way to go about it? Or is there a php function that can see what files are in the directory, open them and then use the info that way? I was told that a database is the way to go but I have no experience of these at all. A database will help you to keep data in separate entities (by keeping X information in an X_info column, Y information in a Y_info column, for example). A database is also very fast. Database knowledge is also worth having on your resume. I recommend you download MySQL, an easy-to-use and free relational-database-management-system. No doubt you've seen a lot of references to it from PHP stuff, because the two are practically hand-in-hand partners. If you can afford a book, get MySQL by Paul DuBois from New Riders books, and read the first chapter to get a feel for how the SQL language works (so you can write SQL statements into your PHP code). Later when you have more time, finish the book, it's an excellent reference for the MySQL database system. If you don't want to spring for the book but are still interested, there are a million tutorials on using MySQL. But a whole database just for this one script seems to me to be some serious overkill. I recommend that you keep your data in an XML file instead -- this is actually really really easy, probably easier than using MySQL, but not as fast or as powerful for doing queries or searches. But you can mark up the data to keep entities separate, and append new Flash objects' data to a master XML document like you describe. When someone wants to view the gallery, just parse the XML file, or run it through an XSLT style sheet or something. If you need to add to the gallery, just read the XML file into memory, insert the new XML code for whatever it is you need to add, and write it back to the file. The PHP XML functions are at http://www.php.net/manual/en/ref.xml.php and there are tutorials at DevShed, SitePoint, and a dozen other excellent web support sites. Either a database or XML can do what you want, it's really up to you. I think the XML way will get you your results soonest, but learning MySQL will have a long-term value if you ever intend to do any back-end work or just want to know more about databases. It's fun stuff. Erik PS: you can combine XML and MySQL to achieve some really powerful data storage tricks, though sometimes it's overkill to do so (depending on the extent of your project).

Re: [PHP] Use of $_SESSIONS in PHP 4.1.2 with register_globals off

// or to use a current session if the script has been
// passed a session ID via a cookie or GET request
$_SESSION['var1'] = $varablename;
// this tells the script to take the value of the

// var1 variable, which is a session variable.
$_SESSION['var1'] = $_POST['var1'];
// this tells the script that the user-supplied value
// contained by the var1 variable from a POST request
// (usually from a HTML form) should now be contained by
// a session variable called var1.
echo $_SESSION['var1'];
// this does exactly what you think it does, and of
course
// this variable can be manipulated in other ways.
echo()
// is just an easy example.
Since the $_* variables are always global (hence the name
superglobals), you never need to worry about the scope of these
variables. And you never need to use session_register() again. All of
the above code is register_globals=off-compliant.

as remotesite has php installed, of course.
yes, a very clean way to do it (that I've used successfully) is
something like:
$current_page = User Login;
if ($badlogin) {
header(Location: http://domain.com/~eprice/badlogin.php?errormsg=; .
$current_page);
}
This cleanly separates the string from the variable, but they are
concatenated before being passed as an argument to the header()
function. This passes the name of the script as a querystring variable
called $_GET['errormsg'], so that the receiving script can take some
action based on where the user was sent from.

[PHP] --enable-xslt
A few days ago I upgraded to 4.1.2 on my RH 7.2 server. I used --enable-xslt and --with-sablot in my configure parameters because I thought it would be fun to learn more about XSLT with PHP. But there were problems (I don't have the actual error message, and would like to avoid re-configuring to reproduce it if possible), and I needed to drop both of these parameters to the configure script. I was thinking of recompiling with these parameters, and was wondering if anyone on this list knows what is required to do this -- do I need to install a program called Sablotron first? It seems like it. If anyone has a resource or somewhere I should be looking, please by all means point me in the right direction. Erik Erik Price Web Developer Temp Media Lab, H.H.

I'm building it now, as I write this. But I was wondering about some XSLT/PHP style advice... How much of a burden does on-the-fly XSLT place on the server? I mean, relative to a typical setup. I'm playing with the idea of changing all my old HTML to proper XML files, and having PHP generate XML rather than HTML (seems trivial, since PHP doesn't really care what markup language I use to output data -- I could even do it in plain text if I was so inclined). But as PHP generates the XML, there is another step now, and that is the step of running the XML data through one of the XSLT functions (such as xslt_create xslt_run or xslt_process). I'm sure that it all depends on the strength of the server being used, but does anyone have a rough estimate of what kind of burden this extra processing has? Or a reference? Speed isn't the biggest concern, since I don't have a large number of users like some public sites. Mine is an internal site, run off a Linux server w/256MB RAM. But it seems like a lot of work for Apache to process the incoming request, hit up the PHP script, fetch data from MySQL, format the database output into XML, and then run the XML through XSLT to get HTML. And to answer the question do you really need your data in XML?, the answer is no, but this kind of thing gives my boss something to brag about to visitors: this is our temp, he's building our internal schedule-managing database-driven XML-based web application...we pay him little more than minimum wage and he gets no benefits, but he's happy with the work.

[PHP] --with-xml set by default?
Hello, I have a quick question, as I recompile my PHP installation up to 4.1.2: Is the --with-xml option to ./configure a standard these days? I seem to remember that in my initial PHP 4.0.6 installation I used this parameter, but I just did [root@localhost] # ./configure --help | grep 'xml' and the only options that come up are --with-dom, --disable-xml, and --with-xmlrpc. The --disable-xml option leads me to believe that --with-xml is a default option nowadays. However, I could not confirm this in the changelog, and I read all the way back through 4.0.6. Was I just mistaken in the first place by using this option? Thanks, Erik (PS: talking about a source install on Linux) Erik Price Web Developer Temp Media Lab, H.H.

If the timestamp is being used to keep track of RDBMS activity, then use a TIMESTAMP column. By RDBMS activity, do you mean last time user performed x query ? In fact, one of my columns is in fact designed to record things like last time user logged in or whatever, but I am not using the auto-bumping ability of the TIMESTAMP column, but rather creating a new INSERT statement and mysql_query() function to do this job. If RDBMS auto-update would foul things up, use an integer data type. If the date/time is for people/presentation, use a textural format. I'm thinking of not storing any plaintext dates, simply because it's easier to format the mktime() result or TIMESTAMP column to suit my needs. In fact, combining mktime() and date() really seem to be the way to go, which is why I'm using mktime()-generated Unix-style timestamps -- I'll probably never do any database output directly from mysql[client], but rather everything from PHP or perhaps Python if I ever get the time to work on that side project.* If there will be minor processing on the column, eg GROUP BY, ORDER BY, or even , =, etc, then use ISO format ISO = MySQL-style TIMESTAMP? If so, then can't you do ORDER BYs and , = queries with the Unix-style mktime()-generated integers as well? I'm not very experienced with the more advanced MySQL features, though I know they're there and have a decent reference should my script require them. If there will be no processing between what comes out of PHP and what PHP wants back, use a string format column. That's what I was thinking. Apart from some simple queries for results whose dates are between x and y (which should work with mktime()-generated timestamps, right?), it seems that this is the best policy. I should change those columns from TIMESTAMP to INT now before I go any further, just so that I don't accidentally ever bump up the value of the column via an insert or update... Yes you should remember that MySQL will happily cast between string and integer alternative presentations! I'm not sure I understand what this means. I'm guessing that you're suggesting that an INT or a VARCHAR column can both have mathematical operations performed on their values, but perhaps I'm completely off-base.

Well, for one thing, BLOBs don't retrieve as quickly as regular fields, for reasons I don't altogether know. Also, you won't be able to form a query to search for any characteristics of a BLOB, since MySQL will treat the BLOB as a BLOB and doesn't try to imagine what's inside it -- as opposed to, say, a VARCHAR column. There is also a TEXT column type for very long text strings, and I forget whether or not the contents of these can be used in queries -- can someone please confirm this? But basically, almost any other column type is valid subject matter for forming queries. But for storing images and PDFs or other binary data, there's no other way. Note that many MySQL wizards will recommend that instead of storing binary data in a database, use a filesystem to store the data and then use the database to create a sort of directory for quickly locating those files in the filesystem, remembering the path to the file or something. I think this is how a lot of web sites incorporate graphic content in with their database (text) content (including mine). Erik Erik Price Web Developer Temp Media Lab, H.H.

Re: [PHP] Session_start()

When they say that you need to put session_start() before the headers, they're referring to the HTTP headers, not the head tag of the HTML document. HTTP headers are information about the document that tell the client what to expect as it receives the document -- this helps the client decide how best to handle the document. For instance, your client (web browser) might be configured to print any text files directly to the screen, but any XML files need to be parsed properly before being printed. Or perhaps you're not even being sent a document, but rather an MP3 or a PDF. Your browser might want to know a bit about the file that it is being served, before it goes ahead and displays the data on the screen -- in the case of an MP3 or PDF, it might wish to open up Windows media Player or Quicktime or Adobe Acrobat as a helper application (assuming your browser has been programmed to do this). You can learn more about HTTP headers here: http://www.jmarshall.com/easy/http/ NB I haven't read it, I just googled that (but I think I will read it later).

I like the 'function print_name_form()' -- I gather you could do this
for all
the NOT NULL variables that a form requires. Further, would you just
change
the print_name to 'print_whatever-other-variable' that I would want to
check? Is there another way to consolidate the code at this point? Or
would I
just duplicate the code for each not-null variable?
You can name a function whatever you want -- they're arbitrary,
user-defined puppies. HOWEVER, the contents of a function need to do
what you want -- the function that I showed you creates a very specific
input, named name or something like that. So for each other input you
want to create within a function, you'd have to make sure that they
created unique inputs.
Personally, I put all of my inputs into one function, and the function
itself does both the error checking and the form-printing. This is
probably not the cleanest way to do it, but it works -- in this case,
the function is more of a subroutine than a proper function.
(Subroutines and functions are more or less the same thing in PHP,
there's no syntactic difference.)
[Btw, I sometimes long for the old Paradox PAL code that seemed so
difficult
at the time I learnt it -- PHP is very similar, but the syntax seems so
much
more compact.]
If you get to a point where you feel comfortable with PHP, you might
consider investigating the Python language. It's got a very different
feel, for instance you don't use bucks to indicate variable names, and
there are braces around function definitions or if statements. Rather,
you use whitespace to keep code chunks organized. Some people believe
this is a more organized way to write code. Python is probably more apt
for writing standalone programs and scripts, whereas PHP is more apt for
writing web applications, but that's an opinion of mine and you can
really use either language for either of those. www.python.org for more
info.
While we're on the topic of fields ('input type=text) is there anyway
to
include a non-printing space in the data entry, say for 'Name, that
would
not be passed to the database? Thus, on the screen it would appear:
Name: [non-printing space]Andre but in the database entry:
Name:Andre
This isn't a pressing question, and probably is a formatting question,
but I
wonder if it's possible?
Yes, a formatting/HTML question. I learned everything I needed to know
about HTML from Sams Teach Yourself HTML/XHTML in 24 hours or from the
web itself. That book was also super super easy. I'd say a little bit
too easy if you're already learning things like PHP, which are a more
advanced topic. I am not a very good designer, so I can't really answer
your question directly, but I find that forms lend themselves well to
being placed within HTML's tables.
?php
print table
trtdName:/tdtdinput type=\text\ name=\name\
//td/tr
trtdPassword:/tdtdinput type=\password\
name=\password\ //td/tr
trtdFavorite Sushi/tdtdselect name=\sushi\
option value=not badEbi/option
option value=daringTako/option
option value=wimpCalifornia/option
/select/td/tr
/table
;
?
But when you see this in a web page, it is nicely formatted. Don't
forget to customize the way the table looks by declaring borders and
cell spacing in a style sheet.
Also, as an exercise, come up with a clever way to put this code into a
function.
