Dynamically created form elements value not getting in $_POST in php - php

Question

I have created some dynamic text boxes and values according to the no. of cart items selected by a user. The no. of cart items are stored in a cookie and I am trying to do the following:
1) Get the no. of cart items from the cookie named cartcounter
2) Create 'cartcounter' no of text boxes with name itemkey_skey where itemkey is the hash key of each items in user cart.
3) Submit the form
4) Get the keys of the selected items in php
Now I can create cartcounter, the number of text boxes with different values.
But the problem is that I can get only the first text box value in $_POST in PHP. I would like to get all the values of the dynamically created form elements.
Code:
$(document).ready(function() {
if (getCookie("cartcounter") != 0) {
$("#counter").val(getCookie("cartcounter"));
for (var i = 1; i <= cartcounter; i++) {
var ckey = getCookie(i + "_skey");
var element = document.createElement("input");
alert("Element=" + element);
element.setAttribute("type", "text");
element.setAttribute("value", ckey);
element.setAttribute("name", "skey_" + ckey);
var foo = document.getElementById("itmbox");
foo.appendChild(element);
$("#frm").submit();
}
}
else {
alert('Your cart is empty , please choose your product');
window.location = "http://synergiadigital.com/restaurant2/orderFood.php/"
}
});​

I have solved it. The problem was that I was calling the submit function inside the loop. I have solved it by doing:
$(document).ready(function() {
if (getCookie("cartcounter") != 0) {
$("#counter").val(getCookie("cartcounter"));
for (var i = 1; i <= cartcounter; i++) {
var ckey = getCookie(i + "_skey");
var element = document.createElement("input");
alert("Element=" + element);
element.setAttribute("type", "text");
element.setAttribute("value", ckey);
element.setAttribute("name", "skey_" + ckey);
var foo = document.getElementById("itmbox");
foo.appendChild(element);
}
$("#frm").submit();
}
else {
alert('Your cart is empty , please choose your product');
window.location = "http://synergiadigital.com/restaurant2/orderFood.php/"
}
});​
