/**
 * Change the add to cart text on single product pages
 */
add_filter( 'woocommerce_product_single_add_to_cart_text', 'woo_custom_cart_button_text' );
 
function woo_custom_cart_button_text() {
 
  global $woocommerce;
 
  foreach($woocommerce->cart->get_cart() as $cart_item_key => $values ) {
    $_product = $values['data'];
 
    if( get_the_ID() == $_product->id ) {
      return __('Already in cart - Add Again?', 'woocommerce');
    }
  }
 
  return __('Add to cart', 'woocommerce');
}
 
/**
 * Change the add to cart text on product archives
 */
add_filter( 'add_to_cart_text', 'woo_archive_custom_cart_button_text' );
 
function woo_archive_custom_cart_button_text() {
 
  global $woocommerce;
 
  foreach($woocommerce->cart->get_cart() as $cart_item_key => $values ) {
    $_product = $values['data'];
 
    if( get_the_ID() == $_product->id ) {
      return __('Already in cart', 'woocommerce');
    }
  }
 
  return __('Add to cart', 'woocommerce');
}
