Only load scripts and style when page have a form

I write a simple code to enqueue assets only on pages that have a form. Simply add it to your theme functions.php:

// Disable contact-form-7 enqueue actions
remove_action( 'wp_enqueue_scripts', 'wpcf7_do_enqueue_scripts', 10 );
remove_action( 'wp_enqueue_scripts', 'wpcf7_recaptcha_enqueue_scripts', 10 );

// Trigger contact-form-7 enqueue actions when form shortcode is called
function contact_form_7_enqueue_scripts($out){
	wpcf7_do_enqueue_scripts();
 	wpcf7_recaptcha_enqueue_scripts();
	return $out;
}
add_filter( 'shortcode_atts_wpcf7', 'contact_form_7_enqueue_scripts' );
