UPDATED I\'m using jQuery validate plugin and remote method to check email availiability with ajax, but I don\'t understand why ajax calls only once. When e

Answer 1

the reason why ajax fires only once is that you have overwritten the success callback of jQuery validate's remote method. Keep it simple and try something like this:

<input name="email_address"/>

with script

<script>
$(function () {
    $('form').validate({
        rules: {
            email_address: {
                required:true,
                remote: {
                    url: "your_script.php"
                }
            }
        },
        debug: true,
        submitHandler: function () { alert('ok'); }
    });


});
</script>

and php like

<?php 

echo $_GET['email_address'] == "bob";

 ?>

<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">

    $(document).ready(function(){

        $('.checkout-form').validate({
            rules: {
                on0 : {
                    required : true,
                    remote : {
                        url: YOUR_HOST,
                        type: "post",
                        data: {
                            email_address: function()
                            {
                                return $("#email_address").val();
                            }
                        }
                    }
                },
            },
            messages : {
                required:"message",
                remote: "message"
            }
        });
    });
</script>

in html

<input type="text" name="on0" value="Your e-mail" class="form-field no-mr check-email" id="email_address"/>

And in php code

<?php 

echo $_POST['email_address'];

 ?>
