Using sessions between two frames.

[wro]

Hello, I am using two frames, one for navigation and the other for content.  The navigation will display news and other information if there is not a session set, the content, once logged in will set the session then reload the menu frame, however the menu frame isn't picking up on this and continues to display the news and other info.

 

edit: Even if I manually reload the navigation menu frame, it doesn't detect the session =(

 

Menu page.

 

<php
     include 'connect.php';
?>
<?php
if (isset($_SESSION['player'])) 
  {
    echo "<a href=\"overview.php\" target=\"content\"><p align=\"center\">Overview</p></a>";
    echo "<a href=\"town.php\" align=\"center\" target=\"content\"><p align=\"center\">Town</p></a>";
    echo "<a href=\"charsheet.php\" align=\"center\" target=\"content\"><p align=\"center\">Character Sheet</p></a>";
    echo "<a href=\"skills.php\" align=\"center\" target=\"content\"><p align=\"center\">Skills</p></a>";
    echo "<a href=\"market.php\" align=\"center\" target=\"content\"><p align=\"center\">Market</p></a>";
    echo "<a href=\"guild.php\" target=\"content\"><p align=\"center\">Guild Hall</p></a>";
    echo "<p align=\"center\"><img src=\"images/standard.jpeg\" align=\"middle\"></p>";
    echo "<p align=\"center\">HP: xxx/xxx</p>";
    echo "<p align=\"center\">IP: xxx/xxx</p>";
  }
else
  {
    echo "<h2>News:</h2>";
    echo "<p>Frame and menu added 05-26-2010</p>";
    echo "<p>Registration live 05-18-2010</p>";
}
?>

 

Snippet from the authentication page.

 

if($result2)
    {
       session_start();
       $_SESSION['player']=$player;
       print "logged in successfully<br><br>";
       print "<A href='content.php'>Play!</a>";
       print("<script language ='javasript'>top.menu.locatin.reload();</script>");   
    }

You need session_start() at the top of every page that uses sessions.

Thank you, it does output correctly, but gives the following for either logged in or out:

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

 

I'm sure it's something simple, I'll be the first to admit I'm still very new (the session_start is directly below the opening php tag with nothing before it.)

Also attempted  using named sessions, but it didn't work.  Is there a way to check the content frame to see if a session exists and relaying the info to the menu frame so that sessions aren't required in the menu frame.

 

Thanks again

One common overlook is if the page is being included in another page. Remember that session_start must occur before ANY output to the browser (including HTML). Check for whitespacing before your opening PHP tag.

I remember that happening or something in like PHPBB.

 

Make sure you don't have headers already set in your main index (and or) .. maybe you have them set twice.
