Introduction
By default, WooCommerce product pages come with Description, Additional Information, and Reviews tabs. But what if you need to show custom content—like fabric care instructions, sizing charts, or warranty details? In this tutorial, we’ll build a lightweight, code-only solution to add your own product tab.
What You’ll Learn
- Registering a new tab via filter hooks
- Rendering custom HTML content
- Targeting specific products or categories
1. Register the Tab
Add this to your theme’s functions.php (or better, a small custom plugin):
phpCopyEditadd_filter( 'woocommerce_product_tabs', 'vjk_custom_product_tab' );
function vjk_custom_product_tab( $tabs ) {
$tabs['care_instructions'] = [
'title' => __( 'Care Instructions', 'vjk' ),
'priority' => 50,
'callback' => 'vjk_care_instructions_tab_content'
];
return $tabs;
}2. Render the Content
Below the registration hook, define the callback:
phpCopyEditfunction vjk_care_instructions_tab_content() {
echo '<h2>Fabric Care & Handling</h2>';
echo '<ul>
<li>Machine wash cold, gentle cycle</li>
<li>Do not bleach</li>
<li>Hang to dry</li>
<li>Iron on low heat</li>
</ul>';
}
3. Conditional Loading (Optional)
If you only want the tab for a specific category (“Clothing”), wrap the registration in a conditional:
phpCopyEditif ( has_term( 'clothing', 'product_cat' ) ) {
add_filter( ... );
}
Conclusion & Next Steps
You’ve now added a custom, plugin-free product tab to WooCommerce. Customize its title or content as needed—no extra plugins required.
