Can't destroy session vars

Anon

Hi all,
I can't seem to destroy my session vars? I have a whole bunch of them that I use to display values in form fields (user input errors etc) like:

I've tried:

unset($temp_name);
session_destroy($temp_name)

but they don't seem to do the trick, the form when reprinted, still displays these values when I don't want them. Very fustrating!

Any ideas guys?

Cheers

Nick

Hi Nick,

You can destroy a session with session_destroy() or you can unregister a sessionvar with session_unregister(). I think you want to use the session_unregister().

example:
file1
<?php
session_start();
session_register("temp");

$temp = 12;
?>

file2
<?php
session_start();
echo $temp; // prints 12
session_unregister("temp");
?>

good luck! oh, and read the manual...
greetings

I\'ve read the Manual, it\'s a first step every time. Try reading the question!

Hi Nick,

Okay you can say that. But if you had read the manual on session handling functions (http://www.php.net/manual/en/ref.session.php) and the different function, you would have noticed that
session_destroy($temp_name)

cannot work. Why? Because:
"session_destroy -- Destroys all data registered to a session
Description: bool session_destroy (void)"

you see, it says void. So if you want to unregister a sessionvar you use:
"session_unregister -- Unregister a variable from the current session
Description: bool session_unregister (string name)"

Ah! session_unregister is not void but string! Good!

So when you read the manual, read the function description carefully.

Good luck.

I apologise unreservedly.
I was about to ask if you were on drugs or something because you still didn\'t understand my question but I thought I\'d check my question first.
I had indeed written session_destroy() but I had meant to say session_unregister() !
uing session_destroy() never even occured to me because it\'s clearly wrong. I\'m trying session_destroy() (I came staight from the manual to this forum so I guess thats where my confusion occored) and it just won\'t work!
I think the sesion and POST vars are getting confused.
What do you think?

Again, my apologies.

Hi Nick,

Hahaha, drugs! Hihi. ;-) That is really funny! And no, i am not using drugs, i do not need them to be weird. ;-)

I do understand your question, but why your code is not working is a big ?-sign for me.

I hope you worked it out your self or with help from someone else. If not let me know and maybe it is a good idea to view some of you code. Maybe you are doing something wrong in there.

greetings
