Sample code for the WooCommerce Tab Manager plugin to conditionally display a tab based on the product category. To use this code, first go to WooCommerce > Tab Manager > Add Global Tab and create a new global tab, which for this example we'll name "Sample Tab". "Sample Tab" will now show up for every product that uses the global tab layout. Let…

wc-tab-manager-category-tab.php

<?php

add_filter( 'wc_tab_manager_product_tabs', 'wc_tab_manager_product_tabs' );

function wc_tab_manager_product_tabs( $tabs ) {

	global $product;

	foreach ( $tabs as $tab_name => $tab ) {

		if ( 'my-tab' == $tab_name ) {

			$categories = wp_get_post_terms( $product->id, 'product_cat', array( 'fields' => 'names' ) );

			if ( ! in_array( 'My Category', $categories ) ) {
				unset( $tabs[ $tab_name ] );
			}
		}
	}

	return $tabs;
}

Hi Justin, and thanks for sharing this snippet! I tried this code but had no luck. What I'm trying to achieve is to set the Global tabs to 1 category.

I've added this to my theme's functions.php
Here's my code:

add_filter( 'wc_tab_manager_product_tabs', 'wc_tab_manager_product_tabs' );
function wc_tab_manager_product_tabs( $tabs ) {
    global $product;
    foreach ( $tabs as $tab_name => $tab ) {
        if ( 'wapen-info' == $tab_name ) {
            $categories = wp_get_post_terms( $product->id, 'product_cat', array( 'fields' => 'names' ) );
            if ( ! in_array( 'jachtwapens', $categories ) ) {
                unset( $tabs[ $tab_name ] );
            }
        }
    }
    return $tabs;
}
