Editing Custom product tab content in Woocommerce Admin product pages - php

Question

In WooCommerce, I would like to add custom global product tab just like additional info when a new product is created.
I am able to create new tab but cannot update anything on create new product page.
I can see it on display page but how to add info through product edit page. I know I can use custom fields but I am looking to have it on product page to allow shop manager or others to fill this additional shipping tab.
My Code is
add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab' );
function woo_new_product_tab( $tabs ) {
// Adds the new tab
$tabs['test_tab'] = array(
'title' => __( 'Shipping', 'woocommerce' ),
'priority' => 50,
'callback' => 'woo_new_product_tab_content'
);
return $tabs;
}
function woo_new_product_tab_content() {
// The new tab content
$prod_id = get_the_ID();
echo'<p>'.get_post_meta($prod_id,'Shipping',true).'</p>';
}

You can add a custom Metabox in Admin Product pages that will allow Shop Managers to add content for your custom product tab. You will get this:
Here is the code:
// Adding a custom Meta container to admin products pages
add_action( 'add_meta_boxes', 'create_custom_meta_box' );
if ( ! function_exists( 'create_custom_meta_box' ) )
{
function create_custom_meta_box()
{
add_meta_box(
'custom_product_shipping_field',
__( 'Custom Shipping Tab information', 'woocommerce' ),
'add_custom_content_meta_box',
'product',
'normal',
'high'
);
}
}
// Custom metabox content in admin product pages
if ( ! function_exists( 'add_custom_content_meta_box' ) )
{
function add_custom_content_meta_box( $post )
{
$value = get_post_meta( $post->ID, '_shipping_tab', true ) ? get_post_meta( $post->ID, '_shipping_tab', true ) : '';
wp_editor( $value, 'custom_shipping_tab', array( 'editor_height' => 100 ) );
echo '<input type="hidden" name="custom_product_field_nonce" value="' . wp_create_nonce() . '">';
}
}
//Save the data of the Meta field
add_action( 'save_post', 'save_custom_content_meta_box', 10, 1 );
if ( ! function_exists( 'save_custom_content_meta_box' ) )
{
function save_custom_content_meta_box( $post_id ) {
// We need to verify this with the proper authorization (security stuff).
// Check if our nonce is set.
if ( ! isset( $_POST[ 'custom_product_field_nonce' ] ) ) {
return $post_id;
}
$nonce = $_REQUEST[ 'custom_product_field_nonce' ];
//Verify that the nonce is valid.
if ( ! wp_verify_nonce( $nonce ) ) {
return $post_id;
}
// If this is an autosave, our form has not been submitted, so we don't want to do anything.
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
return $post_id;
}
// Check the user's permissions.
if ( 'page' == $_POST[ 'post_type' ] ) {
if ( ! current_user_can( 'edit_page', $post_id ) ) {
return $post_id;
}
} else {
if ( ! current_user_can( 'edit_post', $post_id ) ) {
return $post_id;
}
}
// --- Its safe for us to save the data ! --- //
// Sanitize user input and update the meta field in the database.
update_post_meta( $post_id, '_shipping_tab', wp_kses_post($_POST[ 'custom_shipping_tab' ]) );
}
}
Then your own code will be:
// Add product custom "Shipping" tab
add_filter( 'woocommerce_product_tabs', 'woo_new_product_tab' );
function woo_new_product_tab( $tabs ) {
$tabs['test_tab'] = array(
'title' => __( 'Shipping', 'woocommerce' ),
'priority' => 50,
'callback' => 'shipping_product_tab_content'
);
return $tabs;
}
// The Shipping tab content
function shipping_product_tab_content() {
// The new tab content
$prod_id = get_the_ID();
echo'<div><p>'.get_post_meta( get_the_ID(), '_shipping_tab' ,true ).'</p></div>';
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and works.
