Get WooCommerce product SKU in product pages meta box

You could try to insert a new metabox SKU field on general options product pages this way:

add_action( 'woocommerce_product_options_general_product_data', 'add_the_sku_to_general_product_field' );function add_the_sku_to_general_product_field() {    global $post;    $product_sku = get_post_meta( $post->ID, '_sku', true );    echo '<div class="options_group">';    woocommerce_wp_text_input( array(        'id'                => '_sku',        'label'             => __( 'SKU', 'woocommerce' ),        'placeholder'       => '',        'description'       => __( 'Enter the SKU', 'woocommerce' )    ) );    echo '</div>';}// Saving the Custom Admin Field in general tab products pages when submittedadd_action( 'woocommerce_process_product_meta', 'save_the_sku_to_general_product_field' );function save_the_sku_to_general_product_field( $post_id ){    $wc_field = $_POST['_sku'];    if( !empty($wc_field))        update_post_meta( $post_id, '_sku', esc_attr( $wc_field ) );}

Or alternatively just displaying the SKU…

With this code:

add_action( 'woocommerce_product_options_general_product_data', 'add_the_sku_to_general_product_field' );function add_the_sku_to_general_product_field() {    global $post;    $product_sku = get_post_meta( $post->ID, '_sku', true );    echo '<div class="options_group">';    echo '<p class="form-field _sku_product "><label for="_sku_product">SKU: </label><span style="font-size:120%;">'.$product_sku.'</span></p>';    echo '</div>';}

As I don't use your plugin, I doesn't guaranty that this should work, but you should try it.

The Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Thank you.

The following part of code you suggested it working inside of the plugin now.

global $post;$product_sku = get_post_meta( $post->ID, '_sku', true );

The when I echo $product_skuit returns the value.

Did you set $product variable as a global variable ( global $product; ) ? that already @helgatheviking mention it.

like:

global $product;echo 'SKU: ' . $product->get_sku();
