AJAX with PHP Sessions

[AndrewM16921]

Hey so, I'm trying to get a php session to work with ajax calls from jquery. It doesn't seem to be working, so I'm guessing something like a session id isn't getting sent by the ajax calls. Not sure how to fix this. Googled some stuff, wasn't entirely sure what to make of it all. I'll post some examples I whipped up to test it. Pretty simplistic example. The js below gets "info.php", which should return a couple spans, the first of which (for testing sake) should just increment each time it's called.

$(function(){  $("#sp-info").load("info.php");}

<?php  session_start();  if(isset($_SESSION["uid"]))  {	$_SESSION["uid"] = 1;  }  else  {	$_SESSION["uid"] = $_SESSION["uid"] + 1;  }?><span id="info-left">  Welcome, <? echo $_SESSION["uid"]; ?>!</span>

Don't start the session for the first time in the ajax call, start the session on the parent page first so that they have their session cookie already by the time they start sending ajax requests.

Actually, I just fixed the problem. Stupid mistake! Instead of if(isset($_SESSION["uid"])) I forgot to negate it if(!isset($_SESSION["uid"])) But thank you!
