   <?php foreach($posts as $post): ?>
   <?php if(userLiked($post['post_id'])): ?>
   <svg class="solid-heart heart" aria-hidden="true" focusable="false" data-prefix="fas"  data-icon="heart" class="svg-inline--fa fa-heart fa-w-16" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">

   <?php endif; ?>
   <?php endforeach ?>
</div>

基本上我想要当我单击SVG图像常规心脏..然后应将其替换为SVG图像常规心脏...并将值发送到数据库，这是我的javascript代码

$(document).ready(function () {
    $('.heart').on('click', function () {
        var post_id = $(this).data('id');
        $clicked_btn = $(this);
        if ($clicked_btn.hasClass('regular-heart')) {
            action = 'like';

        }
        else if ($clicked_btn.hasClass('solid-heart')) {
            action = 'unlike';

        }
        $.ajax({
            type: 'post',
            url: 'index.php',
            data: { 'action': action, 'post_id': post_id },
            success: function (data) {
                $('#error').html(data);

                if (action == 'like') {
                    $clicked_btn.removeClass('regular-heart');
                    $clicked_btn.addClass('solid-heart');
                } else if (action == 'unlike') {
                    $clicked_btn.removeClass('solid-heart');
                    $clicked_btn.addClass('regular-heart');
                }
            }
        })
    })
})

当我单击常规心脏时，就会出现问题，它不会变为坚实的心脏。请通过代码帮助我实现此功能
