修复WooCommerce自定义端点无法显示YITH心愿单内容问题

Let's break down the issues with your code and fix them step by step:

1. Incorrect Action Hook Name #

The biggest blocker here is the wrong hook used to render the endpoint content. WooCommerce follows a strict hook format for custom account endpoints: woocommerce_account_{your-endpoint-slug}_endpoint.

Since your endpoint is yith-my-wishlist, the correct hook should be woocommerce_account_yith-my-wishlist_endpoint — not the generic woocommerce_account_special-page_endpoint you used before.

2. Fix the File Path (For Your Copied Template Setup) #

Relative file paths in child themes can be unreliable, especially when WordPress is loaded from different contexts. Use WordPress's built-in get_stylesheet_directory() function to get the absolute path to your child theme folder, ensuring the server always finds your copied template.

Update your content rendering function like this:

function my_custom_endpoint_content() {
    // Get absolute path to the wishlist template in your child theme
    $wishlist_template = get_stylesheet_directory() . '/yith-woocommerce-wishlist/wishlist-view.php';

    // Add a safety check to avoid fatal errors if the file is missing
    if ( file_exists( $wishlist_template ) ) {
        include $wishlist_template;
    } else {
        echo '<p>' . __( 'Wishlist content could not be loaded.', 'woocommerce' ) . '</p>';
    }
}
// Hook to the correct endpoint action
add_action( 'woocommerce_account_yith-my-wishlist_endpoint', 'my_custom_endpoint_content' );

3. Better Alternative: Skip Copying Plugin Files (Recommended) #

Copying the entire YITH plugin folder to your child theme creates maintenance headaches — you’ll miss template updates whenever the plugin is updated. Instead, use YITH’s built-in template function to load the official plugin template directly:

function my_custom_endpoint_content() {
    // First confirm YITH Wishlist is active
    if ( function_exists( 'YITH_WCWL' ) ) {
        // Load the original wishlist template from the plugin
        yith_wcwl_get_template( 'wishlist-view.php' );
    } else {
        echo '<p>' . __( 'YITH WooCommerce Wishlist plugin is not active.', 'woocommerce' ) . '</p>';
    }
}
add_action( 'woocommerce_account_yith-my-wishlist_endpoint', 'my_custom_endpoint_content' );

4. Final Checks to Ensure Everything Works #

• Flush Rewrite Rules: Even with your flush function, manually trigger this by going to Settings → Permalinks in your dashboard and clicking "Save Changes" (no edits needed). This registers your new endpoint properly.
• Verify Menu Order: Double-check your my_custom_my_account_menu_items() function to ensure yith-my-wishlist is uncommented and placed where you want it in the menu.

After applying these fixes, your wishlist content should load correctly in the My Account section.
