sending a variable through a click

shamil

Hi,
my problem is that i have a table ina simple html page and in the table there are images.Does someone know how do i do to get a variable sent to another page, so as to have only one page displaying the image depending on the image clicked on the previous page?
I've tried something but on the next page "Unidentified variable"..

there are two ways: by <form> and wrinting variables in url.

f.e. <a href="index.php?pic=2">Next picture</a>

with form: type=hidden name=2
type=submit value=Next Picture

or smth like that.

i've tried <a href=target.html?variable=12>link</a>
but when i use $varaible in second page; it tells me that the varaible is undefined..and i don't really know whether its gets the value....

<?
// first.php
print "<a href=target.php?variable=12>link</a>";
?>

<?
// target.php
print $_GET[variable];
?>

To be more specific, for all of the newbies running around here, since PHP 4.1.x request variables are NOT automatically registered in the Global namespace. You must either change the value of Register_Globals in your PHP.INI (not recommended) or retreive them in your script from the super global arrays.

$x=$_GET['yourvar'];
$x=$_POST['yourvar'];
$x=$_COOKIE['yourvar'];
$x=$_REQUEST['yourvar'];

Note: the REQUEST will pull gets, posts, and cookies. But use it with caution. You don't want evil users figuring out they can overide your variable by using another method.
