Need assistance with Show/Hide behaviour

I have a website at http://www.pap911rescue.com, I would like to add this site is in the testing phase. I have a log in form in a drop down element which uses Project 7 Elevator Panel Magic. I am referring to the green drop down bar and specifically the last tab (Member Login)

Once the member is logged in I want to somehow show a "Log out" link that will show on every page in the site, I would prefer not to have the log-out link show unless the user is logged in. If this is not possible, does any one have any other suggestions?

The log in form is in an include file "epm.inc.php" So my question is, can this be accomplished and if so, how? I own just about every one of the Web Assist products but up to this point I haven't been able to figure out which product to use to accomplish this task.

Thanks for any and all help.

How you will show or hide the logout link will depend on how your login is setup. How do you determine if a user is logged in or not? Are you setting any session variables when a user logs in? If so you can check for these variables having a value to determine if you should show the logout link like this:

php:
<?php if (isset($_SESSION['userID']) || $_SESSION['userID'] != ""){ //user is logged in ?>

<a href="your logout page">logout</a>
<?php } else { //the user is not logged in ?>
<a href="your login page">login</a>
<?php ?>

Hi Eric,
Thank you for your quick response. My login is set-up with the User Registration Solution Pack, so I would presume that a session variable is set once a user is registered, and then logs in. Would I be correct in assuming this?

If that is correct, then would the code you provided still work, also, does this code need to be on every page in the site. One more question, does the php code for the login form need to also be on every page or can it be put in the include file?

Remember in my original post, my login form is in an include file that is included in the Elevator Panel Magic widget from Project 7. The link again is www.pap911rescue.com the login form is in the green menu bar directly below the main nav bar, and it is the far right under member login.

Again thank you for your help and excellent products. As I mention I own almost every extension and now quite a few of the solution packs.

The userID session variable should be set when a user logs in, so this check should work to determine if a user is logged in or not.

If you have the login form in an include file that you can just add this code directly into your include file. It should have the same effect as if you put the code directly on the page.

Eric, again thank you for your prompt reply, and it was spot on, it worked. So now I am happy that I know exactly how to work this out, but, I since have needed to rethink my entire menu system so things have changed a bit.

Sorry I asked the questions and you responded, and I wasted both of our time. But I am now headed in a different direction, I guess I should have stuck with the planning stage a little longer.

Have a good day.
