[SOLVED] session variable

[waz]

how am i surpose to set a variable from the previous page  check if its same as before if it is then leave the session variable at same value if not change it to $_post['text'] which is the new value to use .

 

but code doesnt seem to work anyone know why.

<php

session_start();

if($_SESSION['Test'] <> $_POST['textfield']) {

    echo $_POST['textfield'] && " is not same as the session which is " && $_SESSION['Test'];

}else{ $_SESSION['Test'] = $_POST['textfield'];

}

?>

 

 

its really that simple but i cant seem to get it to remeber also its on a php self form

 

thanks waz

Your logic is wrong. If it's not the same, <>, then set the session variable, otherwise it never reaches the $_SESSION['Test'] = $_POST['textfield']; line... unless of course you enter in nothing for the first time vising the site (without the session variable set already).

I don't know what the &&'s are for, but you should use . (dot) to join strings:

 

$_POST['textfield'] . " is not same... " . $_SESSION['Test'];

when it loads there is a default value in the $_POST['textfield']
