Quick hack / jQuery plugin to enable visual star ratings from Gravity Forms radio fields.

gravityforms-star-ratings.html

<!--

GRAVIY FORMS NOTES:
1. Create a “radio” group on any form
2. In the “appearance" tab, give the custom css class `js-gf-rating-stars`
3. The radio values should be in order from low -> high (1,2,3,4,5,etc…).
4. You can have as many stars as you want, it’s based off the number of radio elements in the group.
5. You could technically have as many groups of ratings stars as you want.

JS CONFIG:
This assumes you are using some iconfont, but the setup would work otherwise with some custom css.
Default assumes font awesome. To modify the icon font, just follow the below example:

$('.js-gf-rating-stars').gformsRatings({
  iconClass: "class-name-for-your-icon-fonts-star-icon"
});

-->
<style type="text/css">
.gf-rating-star {
    color: gray;
    cursor: pointer;
    font-size: 2em;
}
.gf-rating-star + .gf-rating-star {
    padding-left: 4px;
}
.gf-rating-star-active {
    color: orange;
}
</style>
<script>
(function($) {

    $(document).ready(function() {
        $('.js-gf-rating-stars').gformsRatings();
    });

    // The meat and potatoes
    $.fn.gformsRatings = function( options ) {

        // Setup options
        var settings = $.extend({
            'labels' : false,
            'activeClass' : 'gf-rating-star-active',
            'iconClass' : 'fa fa-star'
        }, options);

        return this.each(function() {

Hi @SimonVetterli - can you be more specific about your issue?
"They get all the same classes" is too vague for me to spend time helping.

Hi @taeo

Okay...

I have on the link I provided 5 radio group fields: https://chilli-cycling.asia/customer-review-form/

Each of them I have a separate script:

`<script>
(function($) {

$(document).ready(function() {
    $('.js-gf-rating-stars-1').gformsRatings();
});

// The meat and potatoes
$.fn.gformsRatings = function( options ) {

    // Setup options
    var settings = $.extend({
        'labels' : false,
        'activeClass' : 'gf-rating-star-active-1',
        'iconClass' : 'far fa-star'
    }, options);

    return this.each(function() {

        // Store the object
        var $this = $(this),
            $container = $('.ginput_container', $this),
            $radioGroup = $('.gfield_radio', $this),
            $radios = $('input[type="radio"]', $radioGroup),
            $stars = null,
            $currentIndex = null;

        // Initialize
        var init = function() {

            $radioGroup.css('display', 'none');
            $wrap = $('<div class="gf-rating-stars-1"></div>');
            for (var i = 0; i < $radios.length; i++) {
                var label = $radios.eq(i).siblings('label').text(),
                    value = $radios.eq(i).val(),
                    $star = $('<i class="js-gf-rating-star-1 gf-rating-star-1"></i>');

                $star
                    .addClass(settings.iconClass)
                    .data('index', i)
                    .data('value', value)
                    .data('label', label)
                    .attr('title', label)
                    .appendTo($wrap);
            }
            $wrap.appendTo($container);
            $stars = $('.js-gf-rating-star-1');
            // Star Interactions
            $stars.on('hover', function() {
                handleHover($(this));
            }).on('click', function() {
                handleClick($(this));
            });

            // Restore to currently checked next field
            $wrap.on('mouseout', function() {
                $checked = $radios.filter(':checked');
                if (!$checked.length) {
                    $stars.removeClass(settings.activeClass);
                } else {
                    highlight($currentIndex);
                }
            });
        }

        var highlight = function(index) {
            $stars.filter(':gt(' + index + ')').removeClass(settings.activeClass);
            $stars.filter(':lt(' + index + '), :eq(' + index + ')').addClass(settings.activeClass);
        }
        var handleHover = function(el) {
            var index = el.data('index');
            highlight(index);
        }
        var handleClick = function(el) {
            var index = el.data('index');
            $currentIndex = index;
            $radios.eq(index).trigger('click');
        }
        // Kick it off
        init();
    });
};

})(jQuery);
</script>`

With different classes defined.

But when hovering the second one, it only change the colors respectively the status to active of the first one. when hovering the fourth one, it changes the status to active on the first one.

Anything I am missing?

Here is a fixed version which addresses the issue with multiple radio groups. Also, handleHover gets now called and clicking a star immediately makes it selected.

@timoh6 @taeo huge thanks to both of you, this was exactly what I needed, works a charm!

I created a form and had this working fine and then duplicated that form to work off of and it won't work on the second form. Any suggestions?
