captcha validation using hash5
I am using metadata plugin. I want to use validation where I have a hidden field that contains hash5 value of captcha text and I have to validate it with what user enters in captcha field, convert that value to hash5 and then compare with the hidden field. How can I do that? I have other fields in the form too and I want this to be added in the script.
<script type="text/javascript">
$().ready(function() {
var container = $('div.container');
// validate the form when it is submitted
var validator = $("#registrationform").validate({
errorContainer: container,
errorLabelContainer: $(container),
//wrapper: 'li',
meta: "validate"
});
$(".cancel").click(function() {
validator.resetForm();
});
});
</script>
