Tips for transferring the anchor value using jQuery AJAX to PHP

I have been attempting to use jQuery to send the values of a couple of anchors to a PHP file, but I am not receiving any callback from the PHP script.

<div class="result"></div>

<a href="#" value="5" class="star">Star 5</a>
<a href="#" value="4" class="star">Star 4</a>
<a href="#" value="3" class="star">Star 3</a>
<a href="#" value="2" class="star">Star 2</a>
<a href="#" value="1" class="star">Star 1</a>

Here is the jQuery code:

$('a').on('click', function(e) {
    e.preventDefault();

    var star = $(this).attr('value'); 

    $.ajax({
        url: 'process.php',
        type: 'POST',
        data: { star: star },

        success: function(data){
            $('.result').html(data);                        
        }       
    });
});

And this is the PHP code (process.php):

if (isset($_POST['star'])) {        
    $star = $_POST['star'];
    echo $star;
}

What could be causing this issue?

My objective is to click on "Star 5" and receive the value "5" back. Click on "Star 4" and get the value "4" back, and so forth...

Answer №1

value is not a valid attribute for <a> tags. Refer to this link for the list of available attributes.

I suggest using the following HTML code:

<div class="result"></div>

<a href="#" data-value="5" class="star">Star 5</a>
<a href="#" data-value="4" class="star">Star 4</a>
<a href="#" data-value="3" class="star">Star 3</a>
<a href="#" data-value="2" class="star">Star 2</a>
<a href="#" data-value="1" class="star">Star 1</a>

<script>
$('a').on('click', function(e) {
    e.preventDefault();

    var star = $(this).data('value');

    $.ajax({
        url: 'process.php',
        type: 'POST',
        data: {star:star},
        success: function(data){
            $('.result').html(data);                        
        }       
    });
});
</script>
