Want to display extra content on your WooCommerce product page? You can add a custom tab using a simple code snippet and a template file. Here’s how:

Step 1: Edit Your Theme’s Functions File

In the WordPress admin, go to Appearance > Theme Editor and open functions.php from your active theme.

Step 2: Insert Custom Tab Code

Add this code to register and display your new tab:

function custom_product_tab_content($tabs) {
    $tabs['custom_tab'] = array(
        'title'     => __('Custom Tab', 'your-text-domain'),
        'priority'  => 50,
        'callback'  => 'custom_tab_content'
    );
    return $tabs;
}
add_filter('woocommerce_product_tabs', 'custom_product_tab_content');

function custom_tab_content() {
    include('custom_product_tab.php');
}

Step 3: Build the Tab Content File

Create a file called custom_product_tab.php in your theme folder. Add any content you want to show — FAQs, galleries, size charts, etc.

Step 4: Upload the File

Make sure custom_product_tab.php is uploaded to the correct theme directory.

Step 5: Optional Styling

Apply custom styles in your main stylesheet or directly in the template file to make your tab visually consistent with the theme.

Step 6: Preview and Test

Save the changes and check a product page to confirm that your custom tab appears and functions properly. Note: Use a child theme or plugin for these changes to prevent loss during theme updates. Always back up your site before editing theme files.
