add-to-woocommerce-additional-info-tab-single-product.php

<?php
// This code should be added to the functions.php file of the child theme
// Add custom info to Additional Information product tab

add_filter( 'woocommerce_product_tabs', 'woo_rename_tabs', 98 );
function woo_rename_tabs( $tabs ) {
    global $product;
    $tabs['additional_information']['callback'] = 'custom_function_name'; // this is the function name which is included below
    return $tabs;
}

function custom_function_name(){
	echo 'New Content Here'; //add anything you want to show before the default tab content
	woocommerce_product_additional_information_tab(); // This function calls  wc_get_template( 'single-product/tabs/additional-information.php' );
	echo 'New Content Here'; //add anything you want to show after the default tab content
}
?>

Wow,
Gratful to you for this precious peice of code. Thanks for great work :)

@AndiZu2

I hadn't figured out how to edit the content within the table itself. This snippet was just to show how to content before and after the table. I'm sure there is a way, but I haven't needed to investigate it yet, so I'm not sure.

@ben-heath , hi

I have these code

---

add_filter(` 'woocommerce_display_product_attributes', 'custom_product_additional_information', 10, 2 );
function custom_product_additional_information( $product_attributes, $product ) {
//row1
$product_attributes[ 'attribute_' . 'custom-two' ] = array(
'label' => __('ISBN'),
'value' => $product->get_meta('_isbn'),
);
return $product_attributes;
}

Is work for me,
but can't achieve hide, if value is empty.

Thank you
