On a loop that performs data from custom meta field, to check if the meta key has value or exist, we can use the following query:

$testimonials = array(
	'post_type' => 'projects',
	'posts_per_page' => 4,
	'meta_key' => 'testimonial',
	'meta_value' => array(''),
	'meta_compare' => 'NOT IN'
);

The above code can be used in WordPress older than 3.5 but it still usable in the latest version of WP, currently 5.1.

By default, if you use Gravity Forms, after you complete a form, a notification will be shown, and the form will be dismissed. Below is the script to retain the form after a form is submitted.

Just paste into functions.php and change the _id with the form ID.

add_filter( 'gform_pre_submission_filter_ID' , "show_confirmation_and_form" , 10 , 1 );
function show_confirmation_and_form($form) {
  $shortcode = ' . '" title="false" description="false"]';

  if ( array_key_exists( 'confirmations' , $form ) ) {
    foreach ( $form[ 'confirmations' ] as $key => $confirmation ) {
      	$form[ 'confirmations' ][ $key ][ 'message' ] .= $shortcode;
    }
  }

  if ( array_key_exists( 'confirmation' , $form ) ) {
    	$form[ 'confirmation' ][ 'message' ] .= $shortcode;
  }
  return $form;
}

I found this script somewhere, but I will credit the original source once I found it.
