Sessions....am I missing something?

Anon

I'm just starting to work with PHP sessions but I am running into some trouble...mostly they don't seem to work for me at all. I am working with two very simple test files in order to get the basics down.

In the first file I set a session variable $test, then as a quick check we output it again. I also provide a link to the second page in order to see if the variable transfers. The source code of the page is as follows:

<?php
session_start();
session_register("test");
$test = "test";
?>

<head>
<title>Session test</title>
</head>
<body>
<?php

echo "the value of our session variable is: " . $test;
?>
<a href="test2.php">Let's try Test on a second page</a>

I get the following output:
the value of our session variable is: test Let's try Test on a second page

The second page is even simpler simply echoing the variable $test. Source code is as follows:

<head>
<title> session test 2</title>
</head>
<body>
<?
echo "the value of \$test is $test";
?>
</body>

Output looks like this:
the value of $test is

I have no idea why the variable is not passing from one page to another.

Any help is greatly appriciated.

you have to register the variable after you have populated it.

like this:

session_start();
$test = "test";
session_register("test");

then if you change the value of that variable again before the end of the script/page and you want to pass that new value you have to register it again, like this:

$test = "pizza";
session_register("test");

and now the variable $test will equal "pizza".

hope this helps, good luck!!

hey andy,

you need to put the session_start() and the session_register() on every page where you plan to use the sessions. the code will check to see if a session is started and register the session variables, it will not start a new sesssion unless one is not active, nor will it overwrite the session var of $test....like below

<?
session_start();
session_register('test');
?>
<head>
<title> session test 2</title>
</head>
<body>
<?
echo "the value of \$test is $test";
?>
</body>
