Non purchasable products with Call to Order buttons in WooCommerce

In a recent Genesis customization project I completed, the requirement was to be able to mark specific products as “Not (yet) available for sale” when adding/editing the product.

Additionally, the standard “Add to Cart” buttons on the product archives like the main Shop page should show a custom “Call to Order” text and the single product pages should show custom message along the lines of “To order this product, give us a call at so and so number”.

In this tutorial, I share the details of how the above can be set up in WooCommerce.

All the code below goes in child theme’s functions.php.

Step 1

Add Not Ready to Sell field (checkbox) in the Product data’s General tab.

add_action( 'woocommerce_product_options_general_product_data', 'custom_general_product_data_custom_fields' );
/**
 * Add `Not Ready to Sell` field in the Product data's General tab.
 */
function custom_general_product_data_custom_fields() {
    // Checkbox.
    woocommerce_wp_checkbox(
        array(
            'id'            => '_not_ready_to_sell',
            'wrapper_class' => 'show_if_simple',
            'label'         => __( 'Not Ready to Sell', 'woocommerce' ),
            'description'   => __( '', 'woocommerce' )
            )
    );
}

Step 2

Save the state of the checkbox by updating the value of _not_ready_to_sell meta key (custom field) when the product is saved/updated.

add_action( 'woocommerce_process_product_meta', 'custom_save_general_proddata_custom_fields' );
/**
 * Save the data values from the custom fields.
 * @param  int $post_id ID of the current product.
 */
function custom_save_general_proddata_custom_fields( $post_id ) {
    // Checkbox.
    $woocommerce_checkbox = isset( $_POST['_not_ready_to_sell'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_not_ready_to_sell', $woocommerce_checkbox );
}

Step 3

Mark the “Not ready to sell” products as not purchasable.

add_filter( 'woocommerce_is_purchasable', 'custom_woocommerce_set_purchasable' );
/**
 * Mark "Not ready to sell" products as not purchasable.
 */
function custom_woocommerce_set_purchasable() {
    $not_ready_to_sell = get_post_meta( get_the_ID(), '_not_ready_to_sell', true );

    return ( 'yes' === $not_ready_to_sell ? false : true );
}

Step 4

This will change the text of non-purchasable products’ buttons’ (on WooCommerce archives) to Read more.

To change the button text to Call to Order, add

add_filter( 'woocommerce_product_add_to_cart_text', 'custom_product_add_to_cart_text' );
/**
 * Change "Read More" button text for non-purchasable products.
 */
function custom_product_add_to_cart_text() {
    $not_ready_to_sell = get_post_meta( get_the_ID(), '_not_ready_to_sell', true );

    if ( 'yes' === $not_ready_to_sell ) {
        return __( 'Call to Order', 'woocommerce' );
    } else {
        return __( 'Add to cart', 'woocommerce' );
    }
}

Step 5

Add instructions for non-purchasable products on the single product pages.

add_action( 'woocommerce_single_product_summary', 'custom_woocommerce_call_to_order_text', 30 );
/**
 * Add calling instructions for non-purchasable products.
 */
function custom_woocommerce_call_to_order_text() {
    $not_ready_to_sell = get_post_meta( get_the_ID(), '_not_ready_to_sell', true );

    if ( 'yes' === $not_ready_to_sell ) {
        echo '<p class="content-box-blue">Call to order this product. <strong>123-456-7890</strong>.</p>';
    }

}
