Use Font Awesome Stars for Rating

A quick snippet for anyone else looking, here’s how (or my version) on how to use the FontAwesome star icons for star ratings:

/*
Change testimonial star rating to stars
*/
function hms_rating_override( $text ) {

	$matches = null;
	$getMatches = preg_match( '/data-rating=\"(\d)\"/', $text, $matches );

	if ( count( $matches ) == 2 ) {

		$rating = $matches[1];

		if ( $rating == '1' ) {

			return '<i class="fa fa-star"></i>';

		} elseif ( $rating == '2' ) {

			return '<i class="fa fa-star"></i><i class="fa fa-star"></i>';

		} elseif ( $rating == '3' ) {

			return '<i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i>';

		} elseif ( $rating == '4' ) {

			return '<i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i>';

		} elseif ( $rating == '5' ) {

			return '<i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i><i class="fa fa-star"></i>';

		}
	}

	return $text;
}
add_filter( 'hms_testimonials_system_rating', 'hms_rating_override' );
