проверить, не испортил ли редактор код

1. в function.php
// external products in catalog (not in the product cart) > in new browser tab
function my_woocommerce_loop_add_to_cart_link($link,$product) {
if( $product->is_type( 'external' ) ) {
$link = str_replace('<a ', '<a target="_blank" ', $link);
return $link;
}
return $link;
}
add_filter( "woocommerce_loop_add_to_cart_link", "my_woocommerce_loop_add_to_cart_link", 10, 2);

2. в footer.php
if ( ! isset( $porto_footer_escaped ) ) {
wp_footer();
// open links from external product in new tab
echo '<script> var pBut = document.querySelector(".product-type-external form.cart"); console.log(pBut); pBut.setAttribute("target", "_blank"); </script>';

echo "</body>∖n</html>";
}
