Question

I\'m running WooCommerce version 2.5.5. The following lines of code don\'t seem to change the Add To Cart button text on my product page for an item with variations:

<

Answer 1

The correct filter for the single product page is woocommerce_product_single_add_to_cart_text.

function my_custom_cart_button_text( $text, $product ) {
    if( $product->is_type( 'variable' ) ){
        $text = __('Buy Now', 'woocommerce');
    }
    return $text;
}
add_filter( 'woocommerce_product_single_add_to_cart_text', 'my_custom_cart_button_text', 10, 2 );
