wordpress - 自定义产品上缺少“添加到购物车”按钮

Question

代码:

<?php

// --- Product Type: re_subscription -- Custom Fields: type (mls / nomls), duration in days ---

// --- Actions & Filters ---

add_filter('product_type_selector', 're_add_subscription_product_type');
add_filter('woocommerce_product_data_tabs', 're_remove_shipping_menu', 10, 1);
add_filter('woocommerce_product_class', 're_subscription_product_class', 10, 2);

add_action('plugins_loaded', 're_create_subscription_product_type');
add_action('admin_footer', 're_subscription_admin_custom_js');
add_action('woocommerce_product_options_general_product_data', 're_add_custom_settings');
add_action('woocommerce_process_product_meta', 're_save_custom_settings');


// --- Create Product Type ---

function re_add_subscription_product_type($types){
    $types['re_subscription'] = __('RealEstate Subscription');
    return $types;
}

function re_create_subscription_product_type(){
     // declare the product class
     class WC_Product_Re_Subscription extends WC_Product{
        public function __construct($product) {
           $this->product_type = 're_subscription';
           parent::__construct($product);
           // add additional functions here
        }

        /**
         * Get internal type.
         * Needed for WooCommerce 3.0 Compatibility
         * @return string
         */

        public function get_type() {
            return 're_subscription';
        }
    }
}

function re_subscription_product_class($classname, $product_type) {
    if ($product_type == 're_subscription')
        $classname = 'WC_Product_Re_Subscription';

    return $classname;
}


// --- Remove Shipping Menu ---

function re_remove_shipping_menu($tabs){
    /*
        The available tab array keys are:
        general, inventory, shipping, linked_product, attribute, variations, advanced
     */
    unset($tabs['shipping']);
    return $tabs;
}

// --- Show General Tab ---

function re_subscription_admin_custom_js() {
    if ('product' != get_post_type()) :
        return;
    endif;

    ?>
    <script type='text/javascript'>
        jQuery(document).ready(function () {
            // For Price tab
            jQuery('.product_data_tabs .general_tab').show();
            jQuery('#general_product_data .pricing').addClass('show_if_re_subscription').show();

           });
    </script>
    <?php
}

// --- Add Fields ---

function re_add_custom_settings() {
    global $woocommerce, $post;
    $post_id = $post->ID;
    $re_is_mls = get_post_meta($post_id, 're_is_mls', true);
    if($re_is_mls == '')
        $re_is_mls = 'no';

    echo '<div class="options_group show_if_re_subscription">';
    // Duration
    woocommerce_wp_text_input(
      array(
       'id'                => 're_duration_field',

       ));

    // Type
    woocommerce_wp_checkbox(
       array(

       'label'         => __('Is this MLS?', 'woocommerce'),
       'value' => $re_is_mls,
    ));

    echo '</div>';
}

function re_save_custom_settings($post_id){
    // Save Duration field
    $re_duration_fielld = $_POST['re_duration_field'];
    if(!empty($re_duration_fielld))
        update_post_meta($post_id, 're_duration_field', esc_attr($re_duration_fielld));

    // Save MLS option
    $re_is_mls = isset($_POST['re_is_mls']) ? 'yes' : 'no';
    update_post_meta($post_id, 're_is_mls', $re_is_mls);
}

在简单产品上，“添加到购物车”产品按钮显示且工作正常，但在我的自定义产品上，“添加到购物车”按钮缺失。价格仍然显示得很好。

我已发布到/r/woocommerce 并没有得到答案:/希望在这里得到一些东西:3

有人知道去哪里看吗？谢谢:)

类似于Howdy_McGee's answer ，但调用 do_action 而不是 wc_get_template:

add_action( "woocommerce_{$my_product_type}_add_to_cart", function() {
    do_action( 'woocommerce_simple_add_to_cart' );
});
