Magento ajax add to cart product not found error - php

Question

The magento 1.8 ajax cart is showing product not found error
The java script I used is
function setLocationAjax(url,id){
var data = jQuery('#product_addtocart_form').serialize();
data += '&isAjax=1';
url = url.replace("checkout/cart","ajax/index");
jQuery('#ajax_loader'+id).show();
try {
jQuery.ajax( {
url : url,
dataType : 'json',
type : 'post',
data: data,
success : function(data) {
jQuery('#ajax_loader'+id).hide();
setAjaxData(data,false);
}
});
} catch (e) {
}
}
function setAjaxData(data,iframe){
if(data.status == 'ERROR'){
alert(data.message);
}else{
if(jQuery('.block-cart')){
jQuery('.block-cart').replaceWith(data.sidebar);
}
// if(jQuery('.header .links')){
// jQuery('.header .links').replaceWith(data.toplink);
// }
if(jQuery('.cart-top-container')){
//jQuery('.cart-top-container').empty();
jQuery('.cart-top-container').replaceWith(data.toplink);
}
var targetUrl='<?php echo Mage::getUrl('onestepcheckout') ?>';
jQuery( "#dialog-confirm" ).dialog({
resizable: false,
height:140,
modal: true,
buttons: {
"Checkout": function() {
window.location.href = targetUrl;
jQuery(this).dialog( "close" );
},
"Continue Shopping": function() {
jQuery(this).dialog( "close" );
}
}
});
}
}
The product is failing to get the product information required to add to cart. Is there any way to add the product to cart other than this code?

There is also an URL issue I guess Thanks in advance.

Answer 1

You are doing .serialize() on a form element which doesn't have any input elememts. There is a note given http://api.jquery.com/serialize/ about which elements will be serialized using the function.
In setLocationAjax function, you are getting product id. Just pass the product id to the php script.
ie,
jQuery.ajax( {
url : url,
dataType : 'json',
type : 'post',
data: { productId: id },
success : function(data) {
jQuery('#ajax_loader'+id).hide();
setAjaxData(data,false);
}
});
In magento, you can get the product based on the productId and add to cart.
