[SOLVED] session variables get lost on refresh

[xiao]

Is it normal that all session variables get lost when the page is being refreshed?

Depends if your setting the session, without the session_start on top, then refreshing it, then no.

 

Post your code.

Are you setting your session variables equal to something from $_POST EVERY time the script runs?  That'll cause you to overwrite your session vars with blank vars every time you refresh because the post data is gone. =P

[xiao]

if(($_POST['processor'] != "(Make a choice)") && ($_SESSION['processor'] != $_POST['processor'])){
$_SESSION['processor'] = $_POST['processor'];
}

 

So it shouldn't overwrite everytime, right?

It does though.

 

i have a session_start(); (tried to remove it and got quite some errors)

I don't have a session_destroy anywhere.

 

I don't really get it...

Yeah, because when you have a blank $_POST, $_POST['processor'] isn't "(Make a choice)", it's NULL.  Get it?

hmm, makes sense

Thanks. makes me able to do another 20 minutes of programming.

I'll be back with another silly question in a few minutes
