fetching arrays from ajax, php/zf

[cali_dotcom]

hi,
i'm trying to figure out how to pass arrays back and forth from php to javascript and back in the zend framework. i need to do this for check boxes for a project and i canno use zend_form. i came up with a way to do this but the problem i have is that php cannot read the array string tha i pass to it. the javascript i used looks like this:

var cur="";
    var ajaxfields="";
    alert("field count:"+fields.length);
    
    if (fields.length > 0) {
        
        for (var t=0;t<fields.length;t++){
        
            ajaxfields=ajaxfields+escape(fields[t])+"="+escape(document.getElementById(fields[t]).checked)+"&";
        
        }
        
        alert("ajaxfields:"+ajaxfields);
        
        var url="/articles/delete-field"
        var param="c=delete&"+ajaxfields+"sid="+Math.random();
        //alert("param");
        vpMakePostRequest(url, param, deletedone)
    }
}

when i alert the ajaxfields, this is how the string looks like:

ajaxfields:47=false&48=false&49=false&50=true&51=false&52=false&53=false&.

in th php script, i get the c paramemter using(zend):

$this->c = $_POST['c'];
		echo $this->c;

i echo for debugging purposes and i get "delete".
now the problem is fetching the array string so i gp-could go ahead with the script.
NOTE: i couldn't fetch it the same way.

can anyone help me out

have javascript send the script a comma seperated list of only the checked check boxes.

then change:

var param="c=delete&"+ajaxfields+"sid="+Math.random();

to

var param = "c="+ajaxfields+"&sid="+Math.random();

then in the php, get the values into an array by using

explode( ',',$_POST['c'] );

have javascript send the script a comma seperated list of only the checked check boxes.

var param = "c="+ajaxfields+"&sid="+Math.random();

can you tell me how to modify the code to do that? i'm not a javascript guru.
