Работает ли $ cart объект глобально для каждого действия woocommerce?

Question

Я сделал код для удаления товара из корзины в хуке действия woocommerce_cart_item_removed, но когда я добавляю новый продукт в корзину, используя метод add_to_cart, он уменьшает количество товара в корзине, а когда я комментирую код действия woocommerce_cart_item_removed, он отлично работает

Вот мой код функции add_to_cart

add_action( 'wp_ajax_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart');
add_action( 'wp_ajax_nopriv_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart'); 
function woocommerce_ajax_add_to_cart(){

    $product_id = $_POST['product_id']; 
    $variation_id = $_POST['variation_id'];
    $qty = $_POST['quantity_without_attr'];
    $dataArr    = $_POST['dataArray'];
    $term_taxonomy_ids = '';    
    $cart_item_data = array();
    if(isset($_POST['dataArray'])){
        foreach ($dataArr as $key => $value) {  
        $quantity = $value['quantity'];
        unset($value['quantity']);
            if(isset($value['pa_custom-textbox'])){
                $term_taxonomy_ids = wp_set_object_terms($product_id, trim($value['pa_custom-textbox']), "pa_custom-textbox", true);    
                $data = array(
                "pa_".$attribute_name => array(
                    'name' => "pa_custom-textbox",
                    'value' => '',
                    'is_visible' => '1',
                    'is_variation' => '0',
                    'is_taxonomy' => '1'
                    )
                );
                $_product_attributes = get_post_meta($product_id, '_product_attributes', TRUE);
                update_post_meta($product_id, '_product_attributes', array_merge($_product_attributes, $data));
            }

            if(isset($term_taxonomy_ids)){
                $value['pa_custom-textbox'] = $term_taxonomy_ids[0];
            }

            /*Add to cart when attributes are available*/
            /* WC()->cart->add_to_cart( $product_id = 0, $quantity = 1, $variation_id = 0, $variation = array(), $cart_item_data = array() );*/
            if($quantity>0){
                WC()->cart->add_to_cart( $product_id, $quantity, $variation_id, $value);
            }
        }


    }else{
        /*Add to cart when attributes are not available*/
        WC()->cart->add_to_cart( $product_id, $qty, $variation_id, $cart_item_data);        
    }
    /* Insert clone product to cart */
    $get_categories = get_the_terms($product_id, "product_cat");
    if($get_categories[0]->term_id == 26 || $get_categories[0]->term_id == 42 ){
        $found_post = post_exists( 'Art charge/setup fee for '.get_the_title($product_id),'','','product'); 
        echo $found_post;           
        $post_id = '';
        if($found_post == 0){
            $post_id = wp_insert_post( array(
                'post_title' => 'Art charge/setup fee for '.get_the_title($product_id),                 
                'post_status' => 'publish',
                'post_type' => "product",
            ) );
            wp_set_object_terms($post_id, 0 ,'product_cat');
            wp_set_object_terms($post_id, 'simple','product_type' );
            update_post_meta($post_id, '_regular_price','36.00');
            update_post_meta($post_id, '_price','35.00');
            update_post_meta($post_id, '_sale_price','35.00');
            update_post_meta($post_id, '_tax_status','taxable');
            update_post_meta($post_id, '_tax_class','zero-rate');
            update_post_meta($post_id, '_manage_stock','no');
            update_post_meta($post_id, '_virtual','no');
            update_post_meta($post_id, '_downloadable','no');
        }else{
            $post_id = $found_post;
        }
        /* Art charge/ set up fees */

        WC()->cart->add_to_cart( $post_id,1, $variation_id, $value);
    }

}

Вот мой ответ $ _POST

Ниже приведен код удаления

/* Auto delete cloned product */
add_action( 'woocommerce_cart_item_removed', 'after_remove_product_from_cart', 10, 2 );
function after_remove_product_from_cart($removed_cart_item_key, $cart) {
    $line_item = $cart->removed_cart_contents[ $removed_cart_item_key ];
    $product_id = $line_item[ 'product_id' ];
    $removed_product_name = get_the_title( $product_id );

    $cart_contents = $cart->get_cart_contents();
    foreach($cart_contents as $cart_item){
        $pro_id = $cart_item['product_id'];
        $pro_name = $cart_item['data']->get_name();

        if(strpos($pro_name, $removed_product_name) != 0){

            if($cart_item['quantity'] > 1){
                $new_qty = $cart_item['quantity'] - 1;      
                $cart->set_quantity($cart_item['key'],$new_qty,true );
            }else{              
                $cart->remove_cart_item($cart_item['key']);

            }       
        }
    }
    // return $cart;    
}
