Custom metabox content displayed in single product additional tabs on Woocommerce


Thanks to these two posts I have come up with this solution for adding multiple tabs to Woocommerce product detail page.

Editing Custom product tab content in Woocommerce Admin product pages

Adding multiple tabs to WooCommerce single product pages

However, I am still having trouble saving the data and can't figure out how to make each meta_box save. I thought of a foreach statement but I'm not that well versed in PHP to know how the syntax is.

Here is my code. I have 6 tabs I added which show up on the page, and the meta boxes show up in the admin panel but they won't save any input. I only have one that is trying to save right now and I feel like the problem is in the save function.

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_cost_field',
            __( 'Cost and Performance Tab', 'woocommerce' ),
            'add_custom_content_meta_box',
            'product',
            'normal',
            'high'
        );
        add_meta_box(
            'custom_product_environment_field',
            __( 'Environment Tab', 'woocommerce' ),
            'add_custom_content_meta_box',
            'product',
            'normal',
            'high'
        );
        add_meta_box(
            'custom_product_dilution_field',
            __( 'Dilution Directions Tab', 'woocommerce' ),
            'add_custom_content_meta_box',
            'product',
            'normal',
            'high'
        );
        add_meta_box(
            'custom_product_packaging_field',
            __( 'Packaging and Handling', 'woocommerce' ),
            'add_custom_content_meta_box',
            'product',

            'high'
        );
        add_meta_box(

        add_meta_box(

            __( 'Product Specification Tab', 'woocommerce' ),
            'add_custom_content_meta_box',
            'product',
            'normal',
            'high'
        );
    }
}

//  Custom metabox content in admin product pages

Solution

  • You don't need 6 metaboxes in admin product edit pages and there is a lot of mistakes… Try the following instead:

    // Add a custom metabox
    add_action( 'add_meta_boxes', 'additional_product_tabs_metabox' );
    function additional_product_tabs_metabox()
    {
        add_meta_box(
            'add_product_metabox_additional_tabs',
            __( 'Additional product Tabs', 'woocommerce' ),
            'additional_product_tabs_metabox_content',
            'product',
            'normal',
            'high'
        );
    }
    
    //  Add custom metabox content
    function additional_product_tabs_metabox_content( $post )
    {
        // Cost and Performance
        echo '<h4>' . __( 'Cost and Performance', 'woocommerce' ) . '</h4>';
        $value = get_post_meta( $post->ID, '_cost_performance', true );
        wp_editor( $value, '_cost_performance', array( 'editor_height' => 100 ) );
    
        // Environment
        echo '<br><hr><h4>' . __( 'Environment', 'woocommerce' ) . '</h4>';
        $value = get_post_meta( $post->ID, '_environment', true );
        wp_editor( $value, '_environment', array( 'editor_height' => 100 ) );
    
    
        // Dilution Directions
        echo '<br><hr><h4>' . __( 'Dilution Directions', 'woocommerce' ) . '</h4>';
        $value = get_post_meta( $post->ID, '_dilution_directions', true );
        wp_editor( $value, '_dilution_directions', array( 'editor_height' => 100 ) );
