Hide div unless user logged in

DanDan · January 20th, 2005, 08:25 PM

Hi, I'm really rather new to php so I thought I'd dive in at the deep end...
I have a message board system which displays the message with any comment that have been posted on the message shown below it, with the form to post a new message below that.
I'm using a dreamweaver function to log the user in and I want to hide the form to post new messages unless the user is logged in.
I'm really not sure how to do this and I really don't want to resort to having a seperate page for the form and restricting all access to it if at all possible.

If anyone can help please do, and if you need any of my code (not that I have written any to try and do this yet) feel free to ask for it.

Cheers all..

Depending on your method of keeping track of logged in users, try something like:

Code:

<?php
if(isset($_SESSION['logged_in'])) {
?>
FORM CODE HERE
<?php } ?>

Hi, thanks for the reply...

Like I said I'm using Dreamweaver for the log in script, mainly because I'm not competant enough with PHP to write my own as of yet.
That script seems to be setting the session variables

Code:

    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
    session_register("MM_Username");
    session_register("MM_UserGroup");

I have tried your suggestion of

Code:

<?php if (isset($_SESSION['MM_Username'])) { ?>
form code here
<?php } ?>

And it does a wonderful job of hiding it, yet it does not seem to be working even when I am logged in.

I tried to simply echo the session variable MM_Username but it won't even do that, so I'm assuming there is something wrong with my variable declaration or the actual registering of the variable.

Try switching around the lines you posted to make it like this:

session_register("MM_Username");
session_register("MM_UserGroup");
$_SESSION['MM_Username'] = $loginUsername;
$_SESSION['MM_UserGroup'] = $loginStrGroup;

Or better yet, leave out the session_register lines altogether. session_register is a depreciated function and uneeded:

Good luck,

Thankyou very much for the help... I have actually fixed it now and it's working perfectly. I have also used variations of this script all over the place now so thankyou once again it's becoming very handy...

I might just get rid of the session_register lines if they are depreciated code.. Thanks :)
