Answer 1

Change your if condition to this
if (isset($_POST['review_submit'])) {
$review_content = $_POST['message_review'];
$data_rating = $_POST['data-rating'];
$shop_id = get_the_ID();
if(add_user_review($review_content, $data_rating, $shop_id, $user_avatar)){
echo "<script>alert('success')</script>";
} else {
echo "<script>alert('fail to insert')</script>";
}
}
or you can write this in functions.php aswell
<script>
$( ".review_submit_button" ).click(function() {
alert( "success" );
});
</script>
This is always work for :)
