Hi i have set up a php session using GET but having a bit of trouble calling the information, can anyone see what im doing wrong?
heres what ive got:
Code: Select all
session_start();
foreach ($_GET as $key => $value)
{
$_SESSION[$key] = $value;
}
and to call it i have:
Code: Select all
<?php $_SESSION['url'] echo $_value; ?>
but im guessing this is incorrect ?

The session_start(); should go on top of the page, before you have any output (echo/html).

If Mini's suggestion doesn't work, try searching the error. We have discussed this error message hundreds of times.
