   I am trying to use a session var in order to pass the value of the var around my blog but i cant figure out how to get my session to work basically.

   This is what i have so far:

   In wp-config.php:

   session_start();
   $_SESSION["ses_id"] = $_GET["the_id"];

   This is my plugin:
   

   
   function replace_with_the_id($content)
   {
   //replaces in RSS feed
   if (is_feed())
   {
   $content = str_replace("%my_id%", $_GET['the_id'], $content);
   }
   
   //replaces in content of blog with value of ses_id
   if ($_SESSION["ses_id"])
   {
   $content = str_replace("%my_id%", $_SESSION['ses_id'], $content);
   }
   
   return $content;
   
   }
   
   add_filter('the_content','replace_with_the_id');
   
   

   The RSS part works perfectly and does not need to use any kind of session stuff, but the post content need to use the session var and when i use this method the var is empty...

   any ideas? thoughts? insults :) ?

   I am not looking for someone to just code the whole thing out for me -- any input would be of great help, thank you.

   Is it possible that this is a server setting i need to look into ?

   thank you.

   It should work as you have it. I have just tried your plugin code as well as the session stuff in "wp-config.php". I added the following line to a sample post:

   "BTW: the value you passed in the _SESSION[ses_id] is %my_id%."

   I then entered this URI, specifying the _GET paramater:

   http://localhost/wp210/?the_id=52

   What I got displayed in the post is this:

   "BTW: the value you passed in the _SESSION[ses_id] is 52."

   Which proves that it works.

   It may be the way your "php.ini" file is configured, although I don't know what specifically you should look for other than to see if your webserver allows session handling.

   pizdin_dim, i really appreciate you taking the time to test this out.

   I see your result too... but this is the type of problem i see:

   - access site.com/wordpress/post-title/?the_id=blah, and this prints out "blah" fine
   - click "home" or something so im at site.com/wordpress/
   - access another post and "blah" will no longer print out

   Do you see this behavior too? or maybe know why i see it?

   also, here is a screen shot from phpinfo() of my session config... anybody know what it should be set to, if that is in fact the problem?

   Ok, now I see what you're trying to do. Change the session assignment in "wp-config.php" to say this instead:

   
   if (isset($_GET['the_id'])) {
      $_SESSION['ses_id'] = $_GET['the_id'];
   }
   

   That way, you're only overwriting the $_SESSION variable with the $_GET variable if the latter is specified.

   Thanks. How about you give $10 to your favourite charity instead?

    I actually have about $1k of stuff bagged up waiting for me to take it to a local charity.

    regardless, thank you very much.
