Variables not send to next page

Botkiller

Hi, I have a problem while building an intranet site for my work. When I try to send an variable called id to the next page as in : page.php?id=2 (where 2 is extracted from the database and placed in a while.

When I click the link the id is shown in the address bar, but the page isn't getting it. Anyone know how to fix this or what the problem is?

I'm runing Apache 1.3.33, PHP 5.0.5 and MySQL 5.0.15 with PHPMyAdmin (which is working properly) on a Windows 2003 Server.

Assuming the second page is being passed the following:

/some-dir/page.php?id=2

And you don't have any insane frame sets at work, what code is page.php using to take and action the variable 'id' ?

<?php
echo "<image src=images/mededelingen_titel.jpg><br>";
if($id == ""){

$mededeling = mysql_query("SELECT * FROM tekst WHERE mededeling=1 ORDER BY id DESC");
	while($mede=mysql_fetch_array($mededeling)){
echo "<font face=arial><b><a href=mededelingen.php?id=$mede[id]>$mede[header]</a></b></font><br>";
}
}else{
$mededeling = mysql_query("SELECT * FROM tekst WHERE id=$id");
echo "<font face=Arial><b>$mededeling[header]</b><br>$mededeling[tekst]</font>";

}

?>

Your missing '' for the variable.

Try this... id='.$mede[id].'

It's not the part of sending the id that goes wrong, but receiving it. So when running the page on the server the link becomes page.php?id=2 (if seen for record 2 from the database) so that works, but when I click on it, it should be reading the id part from the link. When I try to echo the $id send to the page it doesn't work. While the address line states: page.php?id=2

The problem is that you are not defining $id properly.

$id will always be null, because you're not getting it from the query string.

Do this:

$id = trim($_GET["id"]);

And put that above your:

if($id == "") {

For better code, use this instead:

if(!isset($id)){

Grats all, I got it running now. I guess I'm still used to the old way of coding which works on the old PHP versions but not the new ones I guess 🙂

Thanks all!

Ok, here I am again with almost the same problem, but this time it is with a form. I use the $PHP_SELF for the form and tried that _GET stuff again, but won't work. What am I doing wrong now?

$SERVER['PHP_SELF']. And of course it's $GET for forms that use a GET method, and $_POST for forms that use a POST method.
