You need to do this:
if($result = mysql_query($detailqry)){
$row = mysq_fetch_array($result);
}
else{
echo "Error: Failed finding task details ".mysql_error();
}
All your fields will be in the array $row. $result is just an
identifier not the actual result set.

somewhere in about here you want to have something like:

[etc]
... and if you are doing a query that will return more than one row then
you should also look at some sort of looping mechanism to step through

Hi all.
I just saw my code laugh at me when this exploded into my face. Can
anyone tell me why isn’t this working? I just copied it from another
page made by me for the same site, changed the parameters and tested it,
but it doesn’t work here… how’s this possible?
****************BEGIN CODE*******************
if (is_uploaded_file($_FILES['revpic']['tmp_name'])){
copy($_FILES['revpic']['tmp_name'],
"/usr/local/www/virtual1/66/175/7/45/html/revpics");
echo "Review's picture uploaded successfully<br>";
$query = "INSERT INTO saav_reviews VALUES (NULL, '$revdate', '$revname',
'$revrev', ".$_FILES['revpic']['tmp_name'].")";
$result = mysql_query($query) or die (mysql_error());
if (!$result){
//Do Things
}
else if ($result){
//Do Things
}
}
else if (!is_uploaded_file($_FILES['revpic']['tmp_name'])){
$query = "INSERT INTO saav_reviews VALUES (NULL, '$revdate', '$revname',
'$revrev', NULL)";
$result = mysql_query($query) or die (mysql_error());
if (!$result){
//Do Things
}
else if ($result){
//Do Things
}
}
****************END CODE*******************
What bothers me, is that I pointed this file to my phpinfo.php and got
an empty array, so there’s no [tmp_name] anywhere… how’s that possible?
And the obvious result, is that the code pass right through to the else
if (!is_uploaded_file… instead of stopping at the if decision, and
stores everything but the uploaded image ¿anyone?

Hello,
I have a form field of the type "scrolling text box" it lets users input a
multiline string. I then pass this string as a variable to a php document
that prints this string to the screen:
print "$mailingAddress<br>";
however..... this outputs it all in one line.
Does anyone have an idea as to how I can print this to the screen in the
same way the user has input the info: in multiple lines?
Thanks in advance :-)
--- End Message ---
--- Begin Message ---
I am guessing you mean the input is a textarea.
At any rate, I believe what you want is nl2br()
Happy hacking.

The text field only has newlines (\n) not breaks.
For starters, in the text area tag, you need wrap="virtual":
<TEXTAREA name="mailingAddress" wrap="virtual" rows="6"
cols="40"></TEXTAREA>
Then instead of
print "$mailingAddress<br>";
try
print nl2br($mailingAddress)."<br>";
... which converts all new lines (\n) into breaks (<br />)

Justin

Hi Richard
If you're using Apache I'd recommend using .htaccess files
that way there is no php needed.
AuthName "Your Directory Service - Authentication"
AuthType basic
AuthLDAP on
AuthLDAPServer ldap://ldap.yourdomain.com/
AuthLDAPBase "ou=Your Division, ou=Staff, o=Your Company, c=US"
require valid-user
If on the other hand you actually want to retrieve data from your LDAP
system then i suggest reading the manual. it's not actually a lot harder
that connecting to RDBMS.
I managed to get a working script straight off the manual page.

Villie,
Might seem a silly question, but do you have gd-2.0.1 installed in
/usr/local/gd-2.0.1?
Which version does phpinfo() say you're running?
What does the libphp4.so file link to? Type "ldd libphp4.so" in your
apache/libexec folder. Perhaps you need to put the path to libgd in
/etc/ld.so.conf?
I can confirm that RH7 with GD-1.8 RPM and custom built PHP+GD-2.0.1 does
work. I normally install libgd in /usr/local and have /usr/local/lib as the
first entry in /etc/ld.so.conf (From memory, I think I did this to get
libgd working with PHP)

The only brain cells I've got awake at this moment figure out that when
copying an upload form/code the "enctype" must be copied as well...
sorry for this. I had some more trouble, but it was solved by giving the
appropriate permissions to the folder.

Does anyone know of a guestbook and messageboard similiar/equiv. to the
ones found here: http://www.scriptarchive.com/ on the homepage.
I know there is a link to PHP on the left, but I've been searching
around and haven't been able to find one that are similiar to the link
above.

I have the following code which works fine in Netscape7 but doesn't in IE5.5
$maker_name = $_POST["maker_name"];
$loc = "show_products.php?maker_name=$maker_name&".SID;
header("Location: $loc");
The problem is that the POST variables are coming in EUC-JP (japanese)
correctly but for some reason IE re-encodes the variable into some other
charset (SJIS I am guessing) when requesting the new page sent in the
Header("location: ") ...
So in Netscape I get redirected to this page:
http://192.168.254.14/show_products_html.php?&maker_name=%C5%ED&PHPSESSID=34fbfc3284514b75887c0a6a593b919c
But in IE I get this instead:
http://192.168.254.14/show_products.php?maker_name=??&;
Is this a bug in IE (of course it is ;)? Is there a work around?
Help!

You should always use a proper full URL in the Location header. Try that
first.
header("Location:
http://192.168.254.14/show_products_html.php?&maker_name=$maker_name&PHPSESSID=$PHPSESSID";);
I doubt this will solve your problem, but it is good practice anyway.
One thing that would help debug a problem like this is to try and view
the raw HTTP, because that will lend some insight as to what character
encoding the Web clients (IE and Netscape) are declaring. My guess is
that the problem lies with the POST (when you receive the maker_name
form variable), because HTTP itself has an ISO-8859-1 character encoding
by definition, so there should be no ambiguity there. Variables that are
posted are contained in the content of the HTTP message itself which is
subject to interpretation based on content encoding.
Anyway, hope that lends some insight and gives you some ideas.
Happy hacking.

I also just noticed that your first variable in the query string (which
begins after the ? character) begins with an &, which is a separator
character. I'm not sure what's going on there, but it should be
something more like this:
header("Location:
http://192.168.254.14/show_products_html.php?maker_name=$maker_name&PHPSESSID=$PHPSESSID";);
Happy hacking.

I just wonder how do you know that the POST variable are in EUC-JP. Did you
set this in your ini? Or, did you encode your php files in EUC-JP and you
have the directive inside <meta> tags?
I think you may want to play with these settings:
mbstring.internal_encoding
mbstring.http_input
mbstring.http_output
mbstring.detect_order
Or, you can try the "Multi-Byte String Functions" (
http://jp2.php.net/manual/en/ref.mbstring.php ) to convert from one encoding
to another. Just experiment a bit... still if nothing works, perhaps, we can
try something again later...
- E
--- End Message ---
--- Begin Message ---
And by the way, please check the NOTE: on
http://jp2.php.net/manual/en/function.header.php for the use of header().
Something's missing in the way you used it--perhaps, this is causing the
problem...
- E
<quoted>
Note: HTTP/1.1 requires an absolute URI as argument to Location: including
the scheme, hostname and absolute path, but some clients accept relative
URIs. You can usually use $_SERVER['HTTP_HOST'], $_SERVER['PHP_SELF'] and
dirname() to make an absolute URI from a relative one yourself:
header("Location: http://".$_SERVER['HTTP_HOST']
.dirname($_SERVER['PHP_SELF'])
."/".$relative_url);
</quoted>

If you're using MySQL - I don't know if COUNT() is a part of SQL'92 - you
can use SELECT COUNT(*) FROM table like this:
<?
echo mysql_result(mysql_query("SELECT COUNT(*) FROM table"),0,0);
?>
The two zeros at the end means that mysql_result is to fetch the first row,
the first column of the result.
(Also, it'll be much faster than mysql_num_rows(mysql_query("SELECT * FROM
table"))

I want to change the default session name 'PHPSESSID' to say ex. 'seid'.
How can I do this without editing to the php.ini since I'm having a site on
a virtual host.
Thanx for help in advance ...

Try putting this at the start of your scripts:
ini_set ('session.name', 'seid');

Hi All,
I suspect this is a commonly asked question but; how do I generate a CSV
files on the fly and get the browser to download it.
Do I actually need to generate a file or can I just generate a variable
contain the data that would be in the file?
Any help is greatly appreciated.
TIA

try making the generated csv file an attachment to the php file... like
so...
<?php
$fileextension="csv";
$filename="report";
$fnsave = "$filename.$fileextension";
header("Content-type: application/force-download");
header("Content-disposition: attachment; filename=$fnsave");
echo '1,2,3,4,5,6,7,8';
?>
usually works for me.
incidentally, what browser version are you using? on what os?

You can give the PHP script the extension .csv and use AddType
application/x-httpd-php .csv to your httpd.conf or .htaccess file.
If you want to use a temporary file, you should use something like
$string = 'a, b, c, d, e, f';
$fp = fopen( 'tempfile.csv', 'w' );
fwrite( $fp, $string );
fclose( $fp );
After file creation you should redirect the user to the .csv file.
The problem here is that you cannot delete the temporary file afterwards.
My first option is the one I'm using myself. You can't put all your faith in
header("Content-disposition: filename=$fnsave");
because most browsers won't understand it (and ignore it). If you give your
php file the .csv extension, then no browser can ignore it. They think it's
a normal .csv file, which should be opened with (for instance) Excel...

Hi,
I have some troubles with PhpMyAdmin and PHP4.2.*
I experimented these couples of installations:
PhpMyAdmin / PHP
2.2.6 / 4.1.2
2.2.7pl1 / 4.1.2
2.3.0 / 4.1.2
2.2.6 / 4.2.1
2.2.7pl1 / 4.2.1
2.3.0 / 4.2.1
2.2.6 / 4.2.3
2.2.7pl1 / 4.2.3
2.3.0 / 4.2.3
with MySQL v3.23.49 on RedHat7.2
PhpMyAdmin works perfectly with PHP 4.1.2 but
with 4.2.* one http request took more than 10 seconds
and the linux box performed a lot of disk I/Os.
PHP MySQL extension seems to be changed since v4.2.0
Where is the problem?
I want to move to 4.2.3 :(

Hi Everyone,
I did a simple test with this script:
<?php
mail("[EMAIL PROTECTED]", "test", "this is a test mail");
echo "done";
?>
I run the script from web accounts on different servers. I can receive the
test mail from some but not from others. Is there any configurations that I
am missing here?
Thanks and regards.

My guesses:
Many mail servers are configured so that they send mail only if the sender
receives mail at the same time. One other possible pitfall is that reverse
IP lookup is not working correctly and your server rejects the mail as it
cannot verify the sender host. Also, many (well configured) servers do not
send when there is no live account for that sender.

if you can't use [] for the checkbox, the only way out is to have unique
name for each checkbox.
otherwise, php will always be returning the value of the last checked
checkbox if all checkboxes share the same name without the [].

This will work:
http://www.php.net/array_merge
Call your checkboxes like so:
a.php
==========================================
<form action="b.php" method="post">
<input type="checkbox" name="a1" value="A"><br>
<input type="checkbox" name="a2" value="B"><br>
<input type="checkbox" name="a3" value="C"><br>
<input type="checkbox" name="a4" value="D"><br>
<input type="checkbox" name="a5" value="E"><br>
<input type="checkbox" name="a6" value="F"><br>
<input type="submit" name="submit" value="SUBMIT">
</form>
==========================================
then post it to the desired page and do something like this:
b.php
==========================================
<?php
$foo =
array_merge($_POST['a1'],$_POST['a2'],$_POST['a3'],$_POST['a4'],$_POST['a5']
,$_POST['a6']);
echo $foo; // Returns an array
echo "<pre>";
print_r($foo); // Look whats in the array
echo "</pre>";
?>
==========================================
Best of luck,

You're query reads like this now
"SELECT * FROM ccl_ teams WHERE username = 'admin'
You need to concatenate the variable with the text (remove the space);
"SELECT * FROM " . $table_prefix . "teams WHERE username = 'admin'
Here is a useful troubleshooting method; if the query returns an error,
print it out. You can generally find errors quite easily.

Maybe you should assign the query to is's own value doing your string
concatenation...
i.e.
$query = "select * ...";
then echo out the query:
echo $query;
I think you will see the problem them, I would guess that when you are adding
the table_prefix to the table name that you are getting an extra space in
there...
So, try that out, and see if it helps

I would like to write a script that would populate someone else's form on
the net and get the results.
Off hand, I imagine I would use fopen() to open up the web page and pass
some variables to it. The problem I have is that the form I want to
populate is a multi-step CGI. Is this possible? How do I continue to pass
variables to a second or third step, sending variables passed on what the
form says to do next (which is predictable)?
This is considering I do not have the cooperation of the web site I am
trying to fill out the form for step by step, and I would like to write this
so it is done in a behind-the-scenes, automated way.
For example: A customer registered with me could ask for a product. My
'agent' would go to the site where the product is sold, login, submit all of
the appropriate information for purchase and shipment, and then come back
with (hopefully) a success message (along with any pertinent information
from the purchase).
Anyone have any ideas, suggestions, or can point me in the right direction?
Thanks,
-Mike

Could someone show me a quick and simple way to randomly sort array
elements? I can't seem to pinpoint the correct parameters in the docs.
Thanks!

You could use array_rand() to take stuff out of the array at random and then
stuff it all back into another array.

But if array_rand() truly pulls out random keys, how do you guarantee
that you are not randomly pulling out the same key as you iterate
through the array?
Perhaps you could set the number of keys to return, to the size of the
array, and somehow, magically, all the keys would be included in the
returned array of keys.
i.e. array_rand ( array , array_size)
I have no idea what this would produce...

>From what I understand about array_rand() and the example in the manual, it
does only pull one of each element of the array. You could easily set up a
script to compare what it is pulling to what the array you putting it into
currently has in it if it didn't.

This appears to work
// Normal array
$a1 = Array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
srand((float) microtime() * 10000000);
$a_temp = array_rand($a1, sizeof($a1));
// Random array
while (list(, $value) = each($a_temp)) {
$a2[] = $a1[$value];
}
print_r($a2);

I'm working on a project for a javascript class, but am having trouble with
passing variables. Unfortunately, I can't do this with PHP (that would be
too easy), but I have to use Javascript to do some calculations and output
based on input from a form on a previous page. I am trying to understand
what all I would need to access the variables from page one:
index.html --> summary.html --> payment.html --> thankyou.html
Order Form Order Summary CC info Thank You/Confirmation
(I understand that these will become .PHP pages when I incl the PHP code)
The Order Form page collects 7 variables:
$state, $Widget1, $Widget2, $Widget3, $Widget4, $Widget5, $Widget6
The Summary page needs to do some calculations, but I can't access the
variables ("variable undefined..." errors) with JavaScript:
$cost1 = $Widget1 * 10.00
$cost2 = $Widget2 * 20.00
etc...
$subTotal = ($cost1 + $cost2 + etc...)
$shipping = ($Widget1 + $Widget2...etc) * 0.1 // fixed 10% charge
$tax = $subTotal * 0.08
$total = $subTotal + $shipping + $tax
What I am *trying* to do, for lack of a better idea, is on the Summary page:
<?PHP
import_request_variables("P");
?>
>From here, I'm not sure what to do. Do I need to print an array? Should
this be done in the <HEAD> of the page? Can anyone offer any suggestions
here???
THANX for any/all assistance!

Just wondering what the best way to validate an entered phone format is? Is
anyone doing this currently?
I have a form field that people enter in information and I want to force
phone entries to XXX-XXX-XXXX.

Thanks all for you submissions. This is what I came up with, where
$this_key is a random selection from the array $the_exploded_ids. I
don't know why, but, array_rand() won't work with selection quanity
parameter of less than 2. Anybody know why?
srand ((float) microtime() * 10000000);
$input = $the_exploded_ids;
$rand_keys = array_rand ($the_exploded_ids, 2);
$this_key=$input[$rand_keys[0]];
$this_key=trim($this_key);

Could someone show me a quick and simple way to randomly sort array
elements? I can't seem to pinpoint the correct parameters in the
docs.
Thanks!
