Hide Q&A tab if data not found

Hii @arumugamact,

There is no direct hook in this case, but you have add following snippet on your child theme or snippet plugin to hide Q&A tab.

function custom_body_classes($classes) {
	if (is_product()) { 
    	$product = wc_get_product();
		$productId = $product->get_id();
        $all_questions = get_post_meta($productId, 'ets_question_answer', true);
        if (empty($all_questions)) {
            $classes[] = 'remove_qa_tab';
        }
    }
    return $classes;
}

add_filter('body_class', 'custom_body_classes',999);

Dear @arumugamact,

If you can’t do the CSS, here is the complete snippet with CSS which will hide the tab.

function custom_body_classes($classes) {
    if (is_product()) { 
        $product = wc_get_product();
        $productId = $product->get_id();
        $all_questions = get_post_meta($productId, 'ets_question_answer', true);
        if (empty($all_questions)) {
            $classes[] = 'remove_qa_tab';
        }
    }
    return $classes;
}

add_filter('body_class', 'custom_body_classes');

function add_custom_css_to_head() {
    echo '<style>
        body.remove_qa_tab .tabs .ask_tab {
            display: none;
        }
    </style>';
}

add_action('wp_head', 'add_custom_css_to_head');
