Passing multidimensional JS array to PHP (ajax)

[cfgcjm]

I've created a multidimensional array in js and I want to pass it to PHP through Ajax and have no clue how to so i'm looking for some direction

Array construction & Ajax call:

function save(numStd){
	
//Find Selected Class
var all = document.all ? document.all :
document.getElementsByTagName('*');
var elements = new Array();
for (var e = 0; e < all.length; e++)
if (all[e].className == 'active')
var currentClass=all[e].id; 
	
var sendParams=encodeURIComponent(numStd)+"&param1="+encodeURIComponent(currentClass);

//Declare array
var array = new Array(3);
for (var i = 0; i < numStd; i++) {
	array[i] = ['', ' ', ' '];
}

//fill array
for (var j = 1; j <= numStd; j++) {
	var ln = document.getElementById("LastName"+j).value;
	var fn = document.getElementById("FirstName"+j).value;
	var ag = document.getElementById("Age"+j).value;
	var h=j-1;
	array[h][0] = ln;
	array[h][1] = fn;
	array[h][2] = ag;
}


        var urlNewStd = "/phpscripts/saveNewStd.php?param=";
	http.open("GET", urlNewStd + escape(numStd)+"&param1="+escape(currentClass)+XXX ARRAY HERE XXX, true);
	document.getElementById("studentresult").innerHTML="<img src='/images/ajax-loader.gif' style='margin:50px 0 0 110px;'/>";
	http.onreadystatechange = handleHttpResponseNewStd;
	http.send(null);*/
}

Hi

I would say, use [tt]JSON.stringify()[/tt] to encode the array in JSON format then use [tt]json_decode()[/tt] in PHP to convert the data back.
