Show link if logged in.

[Dada78]

Hello, I have a website where one section requires a login to get to the user control panel. I would like to add a link on other pages outside of the control panel so that if the user navigates away from the control panel they can click a link to return back to the control panel if they are logged in. How could I go about doing something like this?

 

-Thanks

Just check for the logged in session variable (assuming that you use sessions), and if it exists, just echo a link.

I am using sessions but if I include that to the top of the pages outside of the control panel. Wouldn't that make it where they had to be logged in to view it? If that is the case that is not what I want.

<?php session_start();

if($_SESSION['logged_in']){

echo"The new link for the current user who logged in";

}
?>

That doesn't work, nothing shows. Also that means the link as to be at the very top of the page and I don't want it there. Any other ideas?

Uhh...it can be wherever you want, what in the world are you talking about?

It would work fine if you understand how to use session variables

No it can not be where ever I want it. Session Start has to be and the top of the page before and HTML is outputted. You are right, I don't know how sessions work which is why I am here asking for help. I don't deal with php, I strictly deal with XHTML and CSS. This is was a project started by me and a friend as he knew php. So he was going to do the php and I was going to do the layout and design, which I have done. Only thing is he couldn't finish it because he was killed in a car wreck. So it has left me to try to figure it out and finish.

 

So can anyone help?

session_start() does not dictate where the Output of your variable will be, this does

 

if($_SESSION['logged_in']){

 

echo"The new link for the current user who logged in";

 

}

 

 

So put the IF statement where you want it to display.  Change the name to match the name you use for your session variable that get's set when they log in.

I understand that part but this...

 

session_start();

 

Has to be at the very top of the page before any HTML is outtputed correct?

Yes

Say you have a SESSION variable called $_SESSION['username'] (username) etc. On pages outside of the Control Panel, just place the following PHP (modified according to the session variables you have of course):

 

<?php
if(isset($_SESSION['username'])){ //Change this according to variable name
      
     echo '<a href="controlpanel.php">Control Panel</a>'; //Change url of course.

}
?>

Just curious, I have noticed the two codes that were posted were about the same except one has if(isset and one doesn't have the isset. What is the difference?
