switching $_GET for $_SESSION

[babygodzilla]

I have a function that calls a specific task in the index.php using a $_GET['arg'] variable. the way this task is called is from a link. so its like this:

<a href="index.php?do=yes">click here</a>

is there another way to do this using $SESSION and a hyperlink? basically I'd like to use $SESSION variables as much as I can instead of $GET and $POST variables.

Just put:
$SESSION['arg'] = $GET['arg'];

And they'll be the same thing.

You can read about each of the autoglobals and their functions in the manual.

hmm... well, not to bash your idea, but isn't that kinda useless? I mean that's actually creating an extra variable now. what i wanted to know was if its possible to eliminate the need for the $_GET

The difference being that a GET variable only lasts for 1 request whereas a session variable lasts however long you want it to.

If you think that perhaps could you map a GET request to the sesssion array automatically, no you can't and why would you want to?

ah, i didnt know the get vars last for only one request. well in that case it serves its purpose quite well then. thanks very much!
