variable vs URL

[Lc]

Hi,

It's probably very easy, but I cannot find my mistake:

page1.php

<?php
echo "<a href=page2.php? vartrans=5342>C lic</a>";
?>

page2.php

<?php
echo "$vartrans" ;
?>

When I click on the link on page 1, page 2 appears on the screen but with
the following error message:

Notice: Undefined variable: vartrans in c:\program
files\easyphp1-7\www\page2.php on line 2

What's my mistake?

I use php 4.3.3.

Thank you vm in advance for your help

You're relying on register_global s being on, and they're off.

Use the superglobal array $_GET instead.

<?php // page2.php
echo "{$_GET['vartrans']}";
?>

Use better

<?phP
echo $_REQUEST["vartrans"];
?>

to have both, GET and POST method covered
