php – WP自定义帖子类型已经添加到woocommerce 3.0上面的购物车

我仍然可以通过在’woocommerce_product_class’中添加过滤器,在WooCommerce 2.6中将自定义帖子类型添加到购物车

function wc_product_class( $class, $product_type, $post_type ) {

  if( 'my_custom_post_type_slug' == $post_type )
    $class = 'WC_Product_Simple';

  return $class;

}
add_filter( 'woocommerce_product_class', 'wc_product_class', 10, 3);

//This will echo the carti item id
echo WC()->cart->add_to_cart($custom_post_type_id, $quantity, null, null, array());

不幸的是,这还不适用于最新版本的WooCommerce.有人请帮我解决这个问题的解决方案吗？任何建议,评论和解决方案都非常感谢.

解决方法:

I’m selling a plugin that would enable to use Custom Post Type as “product” of WooCommerce.我做了很多工作.

但这是最重要的部分.
您必须创建自己的数据存储,如下所示：

首先创建一个扩展到WC_Product_Data_Store_CPT的类.这个想法是覆盖检查帖子类型的这个类的现有函数.我找到了执行检查的read和get_product_type.

class WCCPT_Product_Data_Store_CPT extends WC_Product_Data_Store_CPT {

    /**
     * Method to read a product from the database.
     * @param WC_Product
     */

    public function read( &$product ) {

        $product->set_defaults();

        if ( ! $product->get_id() || ! ( $post_object = get_post( $product->get_id() ) ) || ! in_array( $post_object->post_type, array( 'birds', 'product' ) ) ) { // change birds with your post type
            throw new Exception( __( 'Invalid product.', 'woocommerce' ) );
        }

        $id = $product->get_id();

        $product->set_props( array(
            'name'              => $post_object->post_title,
            'slug'              => $post_object->post_name,
            'date_created'      => 0 < $post_object->post_date_gmt ? wc_string_to_timestamp( $post_object->post_date_gmt ) : null,
            'date_modified'     => 0 < $post_object->post_modified_gmt ? wc_string_to_timestamp( $post_object->post_modified_gmt ) : null,
            'status'            => $post_object->post_status,
            'description'       => $post_object->post_content,
            'short_description' => $post_object->post_excerpt,
            'parent_id'         => $post_object->post_parent,
            'menu_order'        => $post_object->menu_order,
            'reviews_allowed'   => 'open' === $post_object->comment_status,
        ) );

        $this->read_attributes( $product );
        $this->read_downloads( $product );
        $this->read_visibility( $product );
        $this->read_product_data( $product );
        $this->read_extra_data( $product );
        $product->set_object_read( true );
    }

    /**
     * Get the product type based on product ID.
     *
     * @since 3.0.0
     * @param int $product_id
     * @return bool|string
     */
    public function get_product_type( $product_id ) {
        $post_type = get_post_type( $product_id );
        if ( 'product_variation' === $post_type ) {
            return 'variation';
        } elseif ( in_array( $post_type, array( 'birds', 'product' ) ) ) { // change birds with your post type
            $terms = get_the_terms( $product_id, 'product_type' );
            return ! empty( $terms ) ? sanitize_title( current( $terms )->name ) : 'simple';
        } else {
            return false;
        }
    }
}

之后,在woocommerce_data_stores中添加一个过滤器并使用您的课程.

add_filter( 'woocommerce_data_stores', 'woocommerce_data_stores' );

function woocommerce_data_stores ( $stores ) {      
    $stores['product'] = 'WCCPT_Product_Data_Store_CPT';
    return $stores;
}

有了它,你将能够添加一个邮政类型的鸟类到购物车.但实际上并不会成功添加到购物车.因为没有价格,购物车会拒绝它.

要解决这个问题,您需要另一个过滤器.以下是添加价格的简单方法.

add_filter('woocommerce_product_get_price', 'woocommerce_product_get_price', 10, 2 );
function woocommerce_product_get_price( $price, $product ) {

    if ($product->get_id() == 815 ) {
        $price = 10;        
    }
    return $price;
}

一旦完成,您将成功添加到购物车.
