How to add another price field in woocommerce?

Question

WooCommerce

Good afternoon. There is a wp + woocommerce site. You need to add another field with the price and display this field on the product page.

Is it possible to do this or just add through attributes?

Answer 1

Adding a field in the admin

add_action( 'woocommerce_product_options_pricing', 'custom_woocommerce_product_options_pricing' );

function custom_woocommerce_product_options_pricing() {
    $price_index = '_custom_price';

    woocommerce_wp_text_input(
        array(
            'id' => $price_index,
            'value' => get_post_meta( get_the_ID(), $price_index, true ),
            'data_type' => 'price',
            'label' => __( 'Custom price', 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')'
        )
    );
}

add_action( 'woocommerce_admin_process_product_object', 'custom_woocommerce_admin_process_product_object', 10, 1 );

function custom_woocommerce_admin_process_product_object( $product ) {
    $price_index = '_custom_price';

    $price = wc_clean( wp_unslash( $_POST[ $price_index ] ) );

    update_post_meta( $product->get_id(), $price_index, $price );
}

Output in a template

$price_index = '_custom_price';

    echo wc_price( get_post_meta( get_the_ID(), $price_index, true  ) );

There was another question. You can display this parameter for batch editing in the admin panel when selecting several products and selecting the "Edit" > "Apply" item.
