woocommerce 将自定义帖子类型添加到购物车 [英] woocommerce add custom post type to cart

问题描述

我正在使用 woocommerce，我创建了一个自定义帖子类型，必须将其视为产品，用户可以添加到购物车.我跟着这个教程http://reigelgallarde.me/programming/how-to-add-custom-post-type-to-woocommerce/并确保我的价格字段元键是_price"但它没有用.

I'm using woocommerce and i created a custom post type that has to be treated as a product and user may add to cart. I followed this tutorial http://reigelgallarde.me/programming/how-to-add-custom-post-type-to-woocommerce/ and made sure my price field meta key is "_price" but it didn't work.

当我尝试将此代码添加到functions.php时

when I tried to add this code to functions.php

function reigel_woocommerce_get_price($price = null,$post = null){
if ($post->post->post_type === 'aytam'){
    $price = get_post_meta($post->id, "_price", true);
    }

return $price;
}
add_filter('woocommerce_get_price','reigel_woocommerce_get_price',20,1);
add_action( 'init', 'reigel_woocommerce_get_price' );

也没有用

推荐答案

一直在解决这个问题，由于上面的代码不起作用，我继续制作了一个工作版本.请注意，此代码适用于 Woocommerce 3.6.2(至少)，旨在使其适用于自定义帖子类型 industry-ad ，但您可以更改为欲望

been tackling with this and since the above code didn't work, I went ahead and made a working version. Note that this code works with Woocommerce 3.6.2 (at least) and is intended to make it work with custom post type industry-ad , but you can change to what you desire

class IA_Woo_Product extends WC_Product  {

    protected $post_type = 'industry-ad';

    public function get_type() {
        return 'industry-ad';
    }

    public function __construct( $product = 0 ) {
        $this->supports[]   = 'ajax_add_to_cart';

        parent::__construct( $product );


    }
    // maybe overwrite other functions from WC_Product

}

class IA_Data_Store_CPT extends WC_Product_Data_Store_CPT {

    public function read( &$product ) { // this is required
        $product->set_defaults();
        $post_object = get_post( $product->get_id() );

        if ( ! $product->get_id() || ! $post_object || 'industry-ad' !== $post_object->post_type ) {

            throw new Exception( __( 'Invalid product.', 'woocommerce' ) );
        }

        $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 );
    }

    // maybe overwrite other functions from WC_Product_Data_Store_CPT

}


class IA_WC_Order_Item_Product extends WC_Order_Item_Product {
    public function set_product_id( $value ) {
        if ( $value > 0 && 'industry-ad' !== get_post_type( absint( $value ) ) ) {
            $this->error( 'order_item_product_invalid_product_id', __( 'Invalid product ID', 'woocommerce' ) );
        }
        $this->set_prop( 'product_id', absint( $value ) );
    }
