PHP Session Variables

[jmg498]

Thanks to the user that suggested I use session variables. Unfortunately, I am having some trouble with those as well.

I currently have a webform where the user enters the location of where they want to view the weather information from. Then, I use POST in PHP like this:

post.php script:

<?php
session_start();
echo $_POST["location"];
session_register("location");
require("table.php");
?>

Then, table.php creates an image and then calls another script rdrcfg.php...and within this script, I do the following:

$radar = $location;

Because other parts of this particular script are already set to use $radar. But it doesn't seem to pass the $location variable from the initial post.php script to the rdrcfg.php script. It does seem to go to the table.php script, because I printed it out and it appears.

Any suggestions?

Thanks so much!!!

You really could have kept this in the same thread.

Anyway, to your question, you are creating a session var named location, however there is no actual variable with that name. The variable you get from the form is $_POST['location'] Also you should use the $_SESSIONS super global, as session_register is now deprecated.

Something like this should work:

session_start();
$_SESSIONS['location']=$_POST['location'];

Then in you other script:

session_start();
$radar=$_SESSION['location'];
