Problems with session

wilhud

Hello,

I'm having some problems with my session variables. I'm still new to sessions and php, so I'll try to explain clearly what I've done.

I have a form submitting 3 arrays to my page. When the arrays are submitted, I turn them into comma delimited strings and then try to add them to session variables. After that, I call the session variables to use in my sql query.

Everything works fine on the first attempt. But after that, any time I refresh the page, the variables are lost. And if I got back to the form, the old info is submitted no matter what I do. Here's my code so far...

if ($intLocationID) {

					$sessLocations = implode(',',$intLocationID);
					$sessSemesters = implode(',',$intSemesterID);
					$sessBusinessTypes = implode(',',$intBusinessTypeID);

					session_start();
					session_register('sessLocations','sessSemesters','sessBusinessTypes');

}

Am I doing something wrong with the way I add my session variables? I just call them using $sessLocations, etc. I can't seem to figure it out.

Any help is greatly appreciated.

Thanks,
Wil

It's because I had the session_start inside of my if statement. It worked as long as the if statement was true, but whenever it wasn't the session was never started. I knew I was doing something stupid.

New code is...

session_start();

if ($intLocationID != "") {

					$sessLocations = implode(',',$intLocationID);
					$sessSemesters = implode(',',$intSemesterID);
					$sessBusinessTypes = implode(',',$intBusinessTypeID);

					session_register('sessLocations','sessSemesters','sessBusinessTypes');

}

does that mean u can't start a session inside an if statement?

Please ignore my stupid comment

Just means that you can't start it inside an if statement for what I was trying to do. I was trying to call the session variables outside the if statement, but my session_start was inside. So that's why they were coming up empty.

Initially I asked cos I included them in an if statement, then figured it out myself

it was all to do with an include

from www.php.net/session_register:

Caution
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered(), and session_unregister().

This function returns TRUE when all of the variables are successfully registered with the session.

If session_start() was not called before this function is called, an implicit call to session_start() with no parameters will be made. $_SESSION does not mimic this behavior and requires session_start() before use.

You can also create a session variable by simply setting the appropriate member of the $_SESSION or $HTTP_SESSION_VARS (PHP < 4.1.0) array.
<?php
// Use of session_register() is deprecated
$barney = "A big purple dinosaur.";
session_register("barney");

// Use of $_SESSION is preferred, as of PHP 4.1.0
$_SESSION["zim"] = "An invader from another planet.";

// The old way was to use $HTTP_SESSION_VARS
$HTTP_SESSION_VARS["spongebob"] = "He's got square pants.";
?>

It says that you should set the session variables by $HTTP_SESSION_VARS['Variable'] or $_SESSION['Variable']
