Hiding empty tabs, although empty tabs are not allowed

Hello @teshn,

This is logic that you would need to workout in your themes custom tab template. If you aren’t already overriding the tab template you would do it like this:
https://docs.woocommerce.com/document/template-structure/

Once you have your tab template in your theme you would do something like this in the template:

$product_tabs = apply_filters( 'woocommerce_product_tabs', array() );

$product_tabs = array_filter( $product_tabs, 'filter_empty_tabs', ARRAY_FILTER_USE_BOTH );

function filter_empty_tabs( $key, $product_tab ) {
    $tab_content = '';
    if ( isset( $product_tab['callback'] ) ) {
        ob_start();
        call_user_func( $product_tab['callback'], $key, $product_tab );
        $tab_content = ob_get_contents();
        ob_end_flush();
    }
    return (bool)($tab_content !== '');
}

This will call the tab content callback and filter out any tabs that don’t have content.

Cheers,
Freddie
