Connect AJAX to php function


Recommended Posts



I have never touched AJAX due to never needing it until now. I have looked up some tutorial but dont understand how they link to what you need done.


What I am wanting to do is send the select option value to a php function that then searches the table for the required output  then it in another select tag depending on what option is chosen. I basicly need help defining the need ajax syntax to do such a process? by the way does php create the select tags or javascript?


<select id="elem1">
<option value="101">category one</option>
<option value="102">category two</option>
<option value="103">category three</option>

function getChild(){
        $parent_id = $_GET['elem1];
$result = dbQuery("SELECT cat_id, cat_name
				   FROM catagory_tbl 
				   WHERE parent_id=$cat_id");
