WooCommerce plugin , add variation to cart via Ajax - ajax

Question

Im looking for a solution to add a product variation via Ajax.
As i found out all the WooCommerce basic functions allow adding a product to the cart only if it is not a variation item.
im using <?php echo woocommerce_template_loop_add_to_cart() ?> to display the add to cart button but this button is a regular submit button.
how can i make a variable item use the Ajax add to cart ?

Answer 1

I created and AJAX add to cart for variable products like this:
Sorry about the delay, here is the expanded answer:
I included a new js file called added-to-cart.js and the file contains the following code. There is some extra code for handling a popup and also increasing the cart counter which you might want to remove.
/* Begin */
jQuery(function($) {
/* event for closing the popup */
$("div.close").hover(
function() {
$('span.ecs_tooltip').show();
},
function () {
$('span.ecs_tooltip').hide();
}
);
$("div.close").click(function() {
disablePopup(); // function close pop up
})
$("a.close").click(function() {
disablePopup(); // function close pop up
});
$(this).keyup(function(event) {
if (event.which == 27) { // 27 is 'Ecs' in the keyboard
disablePopup(); // function close pop up
}
});
$("div#backgroundPopup").click(function() {
disablePopup(); // function close pop up
});
$('a.livebox').click(function() {
//alert('Hello World!');
return true;
});
setAjaxButtons(); // add to cart button ajax
function loading() {
$("div.loader").show();
}
function closeloading() {
$("div.loader").fadeOut('normal');
}
// AJAX buy button for variable products
function setAjaxButtons() {
$('.single_add_to_cart_button').click(function(e) {
var target = e.target;
loading(); // loading
e.preventDefault();
var dataset = $(e.target).closest('form');
var product_id = $(e.target).closest('form').find("input[name*='product_id']");
values = dataset.serialize();
$.ajax({
type: 'POST',
url: '?add-to-cart='+product_id.val(),
data: values,
success: function(response, textStatus, jqXHR){
loadPopup(target); // function show popup
updateCartCounter();
},
});
return false;
});
}
function updateCartCounter() {
var counter = $('.widget_shopping_cart_content').text().replace(/\s/g, '');
if (counter == '') {
$('.widget_shopping_cart_content').text("1");
}
else {
$('.widget_shopping_cart_content').text(++counter);
}
}
var popupStatus = 0; // set value
function loadPopup(target) {
var currentPopup = $(target).parents(".single_variation_wrap").find("#toPopup");
var currentBgPopup = $(target).parents(".single_variation_wrap").find("#backgroundPopup");
if(popupStatus == 0) { // if value is 0, show popup
closeloading(); // fadeout loading
currentPopup.fadeIn(0500); // fadein popup div
currentBgPopup.css("opacity", "0.7"); // css opacity, supports IE7, IE8
currentBgPopup.fadeIn(0001);
popupStatus = 1; // and set value to 1
}
}
function disablePopup() {
if(popupStatus == 1) { // if value is 1, close popup
$(".single_variation_wrap > div:nth-child(2)").fadeOut("normal");
$(".single_variation_wrap > div:nth-child(4)").fadeOut("normal");
popupStatus = 0; // and set value to 0
}
}
}); // jQuery End
