如何为WooCommerce定制产品类型插件定制产品页面模板

我试图通过创建一个插件向WooCommerce添加一个新的自定义产品类型。我已经能够在管理界面中获得可用的新产品类型，并且能够自定义添加/编辑产品页面以进行一些自定义设置。

到目前为止，我所不能做的是，当您访问站点上的产品页面时，如何准确地挂钩/修改页面输出。

我找到了几页(here 和here) 这在主题上有一些指导，但我似乎无法根据我的产品类型（底部的代码）来实现挂钩。也许我的名称空间（函数或挂钩名称）有误，这就是为什么它没有被捕获？

插件名称：WooCommerce系列产品

插件文件夹：woocommerce familyproduct

产品类别：WC\\U Product\\U系列

产品类型：wcfp\\u family\\u Product

以下是我开始使用插件添加自定义产品类型时使用的参考资料：here, here 和here

到目前为止，我的插件代码如下所示（一些钩子在测试中被注释掉了）：

add_filter( \'product_type_selector\', \'wcfp_add_family_product_type\' );
function wcfp_add_family_product_type( $types ){
    $types[ \'wcfp_family_product\' ] = __( \'Family Product\' );
    return $types;

                        $json_ids    = array();

                        foreach ( $product_ids as $product_id ) {
                            $product = wc_get_product( $product_id );
                            if ( is_object( $product ) ) {
                                $json_ids[ $product_id ] = wp_kses_post( html_entity_decode( $product->get_formatted_name(), ENT_QUOTES, get_bloginfo( \'charset\' ) ) );
                            }
                        }

                        echo esc_attr( json_encode( $json_ids ) );
                    ?>" value="<?php echo implode( \',\', array_keys( $json_ids ) ); ?>" /> <?php echo wc_help_tip( __( \'Select component parts to display on the product page.\', \'woocommerce\' ) ); ?>
    </p>

    <?php



    echo \'</div>\';
}


add_action( \'woocommerce_process_product_meta\', \'wcfp_save_custom_settings\' );
function wcfp_save_custom_settings( $post_id ){
    //Save the collection of products
    $my_product_ids    = isset( $_POST[\'wcfp_family_product_ids\'] ) ? array_filter( array_map( \'intval\', explode( \',\', $_POST[\'wcfp_family_product_ids\'] ) ) ) : array();
    update_post_meta( $post_id, \'_wcfp_family_product_ids\', $my_product_ids  );
}



/**

 */
function wcfp_custom_product_tabs( $tabs) {
    $tabs[\'rental\'] = array(
        \'label\'     => __( \'Family\', \'woocommerce\' ),
        \'target\'    => \'family_options\',
        \'class\'     => array( \'show_if_wcfp_family_product\'),
    );
    return $tabs;
}
//add_filter( \'woocommerce_product_data_tabs\', \'wcfp_custom_product_tabs\' );



/**
 * Hide Attributes data panel.
 */
function wcfp_hide_attributes_data_panel( $tabs) {

    // Other default values for \'attribute\' are; general, inventory, shipping, linked_product, variations, advanced
    //$tabs[\'general\'][\'class\'][] = \'hide_if_wcfp_family_product\';
    $tabs[\'inventory\'][\'class\'][] = \'hide_if_wcfp_family_product\';
    $tabs[\'shipping\'][\'class\'][] = \'hide_if_wcfp_family_product\';
    $tabs[\'linked_product\'][\'class\'][] = \'hide_if_wcfp_family_product\';
    $tabs[\'attribute\'][\'class\'][] = \'hide_if_wcfp_family_product\';
    $tabs[\'advanced\'][\'class\'][] = \'hide_if_wcfp_family_product\';

    return $tabs;

}
//add_filter( \'woocommerce_product_data_tabs\', \'wcfp_hide_attributes_data_panel\' );

我已经创建/编辑了一个产品，您可以选择哪些产品构成“系列”产品。现在，我将继续创建一个自定义产品页面，该页面将更改客户查看产品时呈现的内容。根据我的搜索，我相信这将是“add\\u to\\u cart”挂钩。

现在，假设“add\\u to\\u cart”函数是我想要钩住的，我在插件中创建了一个模板文件夹，然后用PHP脚本和代码钩住add\\u to\\u cart函数，如下所示：

function woocommerce_wcfp_family_product_add_to_cart() {
        wc_get_template( WP_PLUGIN_DIR.\'/woocommerce-familyproduct/templates/wcfp_family_product.php\' );
}
add_action( \'woocommerce_wcfp_family_product_add_to_cart\', \'woocommerce_wcfp_family_product_add_to_cart\' );

在模板文件中，我只有一些用于测试的原始HTML，比如H5标记，所以我知道钩子正在启动。

那么，我做错了什么？
