session variable not displaying

hawkshawmyers

I'm trying to access a session variable and it's displaying nothing. Here's what I do.

In a file, let's call it test.php I do the following:

<?php
session_start();
$name = "testing.....";
session_register("name");
?>

I access another scipt, test2.php, by using the onClick method for a form buttton in javascript in test1.php as:

The test2.php code is:

<?php
session_start();
print "Name: $name";
?>

Nothing displays. Any suggestions?

Hi,
I just finished a site using session variables (www.pnp.sk) I had problems in testing and found that they are unpredictable if you register the same variable more than once. In some cases the variable just dissapears. so use the session_is_registered function to check if a variable has already been registered before registering it.
if this does not help have a look in the /tmp directory and you will find sess_ files and you should see your variable there.

Also I've seen strange results in trying to pass a session variable using a form GET or POST value. I've never been able to get session vars working with forms, so I usually GET/POST temp vars and then set them to equivalent session vars in the page to which the form submits. Watch out for that one as well.

I also tried the following:

test1.php:

<?php
session_start();
session_register("name1");
session_register("name2");
session_register("name3");
session_register("name4");
$name1 = "name1";
$name2 = "name2";
$name3 = "name3";
$name4 = "name4";
?>

test2.php:

<?php
session_start();
if (session_is_registered("name1") ||
session_is_registered("name2") ||
session_is_registered("name3") ||
session_is_registered("name4")){
print "Name1: $name1 <br>";
print "Name2: $name2 <br>";
print "Name3: $name3 <br>";
print "Name4: $name4 <br>";
}else{
print("session not registered.....");
}
?>

The variables show up in my session file in c:\temp (Windows98) directory as:

!name|!name2|!name3|!name4|

but do not display on my page. I get output on my page, but no values.

Could it be something not set up in my php.ini?

This might be a win98 thing but I cannot set the variable directly like:

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

I have to do the following:

$HTTP_SESSION_VARS['name'] = "test";

I can also do the same for arrays:

$HTTP_SESSION_VARS['name'][0] = "Joe";
$HTTP_SESSION_VARS['name'][1] = "Jack";

Then, I can access the data in another page.
Seems like a lot of typing but it's the only thing I've gotten to work. Thanks for the responses.
