I am building a web application in Ajax + Php.
Using Ajax, i would like to pass a javascript array containing some form values to a php script.
The script php then should get the array and access the array data.
But I cant get it working :p
I think I am doing something wrong in my js function...

Here is my form:

<script>var p = new Array()</script>
<form>
<b>Search Content:</b> <input type="text" name="p[]" onkeyup="control(p,'content_get2')">

<b>in</b>
<select name="p[]">
 <? $misc->getSelectCategory(); ?> //fetch data in the db and build the select list
</select>
</form>

Here is my control function in my ajax.js

function control(p,action)
{ 
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
 {
 alert ("Browser does not support HTTP Request")
 return
 }
var url= "include/"+ action +".php"
url=url+"?p[]="+p
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged 
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}

And in my content_get2.php: $p = $_GET["p"];
Since I send my url+"?p[]="+p, i get an array, but its empty...
What do i do wrong?

Please help me!

I recommend http://script.aculo.us/downloads for ajax requests

usage is much easier

function request()
{new Ajax.Request('usethesamepage.php', { method: 'get', parameters: { req: $('formname').serialize()}, onSuccess: function(p)  
{alert(p.responseText);}})}
