Javascript 如何在woocommerce中通过ajax调用从前端添加产品

我使用下面的代码添加产品（自定义新产品到购物车中，该购物车不存在于products表中）

---

我希望上述代码以ajax方式工作，这意味着在向购物车添加产品和更新产品时，页面不得刷新。

您面临什么问题？你没有在问题中描述这个问题。

 //No Errors Found
if ( $error_pTitle == ""  && $foundProduct=="") {
//echo "No error Completed Validation of fields";
//add them in an array
$post = array(
    'post_status' => "publish",
    'post_title' => $customProductTitle,
    'post_type' => "product",
);


//create product for product ID
$product_id = wp_insert_post( $post, __('Cannot create product', 'izzycart-function-code') );   

//type of product
wp_set_object_terms($product_id, 'simple', 'product_type');
//Which Category
wp_set_object_terms( $product_id, $product_CO_terms, 'product_cat' );
//add product meta
update_post_meta( $product_id, '_regular_price', $customProductPrice );
update_post_meta( $product_id, '_price', $customProductPrice );
update_post_meta( $product_id, '_visibility', 'visible' );
update_post_meta( $product_id, '_stock_status', 'instock' );    
$product = wc_get_product( $product_id );

//Add Product To the customers cart once the Product is added
$found = false;
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
    foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
        $_product = $values['data'];
        if ( $_product->get_id() == $product_id )
            $found = true;
    }
    // if product not found, add it
    if ( ! $found )
        WC()->cart->add_to_cart( $product_id,$customProductQty );
 } else {
    // if no products in cart, add it
    WC()->cart->add_to_cart( $product_id,$customProductQty );
}
   }
   elseif($foundProduct!=""){
    echo $foundProduct;
 }
 else
{
  echo "error cant add product ";
  echo $error_pTitle ;

 }
 }
