Alright talking to myself here. One more problem. Whenever this function sorts itself out, the value of the variable I want ends up "undefined".
It starts here in my code with this link. $sort is the variable that's giving me trouble. If I echo it here, it works correctly.
<a id='showMoreLink' onclick='showMorePosts($showMoreCount,$sort)'>Show more...</a>
Here is snippets of the showMorePosts function
function showMorePosts(str,sortBy)
{
xmlhttp.open('GET','ajaxQueries.php?sort='+sortBy+'&q='+str,true);
xmlhttp.send();
}
And here is where I am echoing $sort in ajaxQueries.php, and getting "undefined". Note that $q works just as it should. (All I can think is q is an integer, and sort is a string)
$q=$_GET['q'];
$sort=$_GET['sort'];
echo $sort.$q;
