Woocomerce custom tab error

Hi, I have added a new tab for a product in the custom tab option for a product. ‘ nutritional information’

I used the reorder PHP from woocomerce to reorder my tabs which works ok on the page where the tab is active. However, on the pages where nutritional information is not displayed an error message appears.
Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /home/natu1091/public_html/wp-content/themes/woodmart/woocommerce/single-product/tabs/tabs.php on line 51

Would you be able to provide the code to display that order only when the woomdart custom tab is shown?

Kind regards, Ciaran

Hello,

What kind of code have you used for this task?

Regards

Hi, I used the following PHP snippet

/**
* Reorder product data tabs
*/
add_filter( ‘woocommerce_product_tabs’, ‘woo_reorder_tabs’, 98 );
function woo_reorder_tabs( $tabs ) {

$tabs[‘decription’][‘priority’] = 5; // Reviews first
$tabs[‘woodmart_custom_tab’][‘priority’] = 10; // Description second
$tabs[‘additional_information’][‘priority’] = 15; // Additional information third

return $tabs;
}

The problem is on pages with no description or woodmart custom tab the following error is displayed.

Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /home/natu1091/public_html/wp-content/themes/woodmart/woocommerce/single-product/tabs/tabs.php on line 51

The code seems to be not correct. Check how it should look from the official WooCommerce documentation https://docs.woocommerce.com/document/editing-product-data-tabs/#section-3
