I have a contact webform that collects a name, email, and message then uses phpmailer to send an email. In order to do some client side validation and provide immediate feedback via ajax, I was looking into jQuery Form Plugin ($form for short) and jQuery Validation Plugin ($validate).
I am a bit confused on how exactly i use these together or if it is even necessary to use both.
$validate's documentation states that using submitHandler function will submit the form via Ajax after it is validated.
$("#myform").validate({
submitHandler: function(form) {
$(form).ajaxSubmit();}
});
That example was provided with a link to $form's page and uses the $form method ajaxSubmit().Am I right to assume that this example provided is using the $form plugin? As in this would be somewhere before the above js to prepare the form for Ajax submission.
$('#myForm').ajaxForm();
Or would the better approach be to validate with rules() specified in $validate, and then use $form's ajaxSubmit?
$('#myForm').submit(function() {
$(this).ajaxSubmit();
return false;
});
lastly, how much server side validation/sanitation with php is necessary afterwards? If $validate allows the form to post, wouldn't i just need to sanitize against xss with:
$name = filter_var($_POST["name"], FILTER_SANITIZE_STRING);
$email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);
$message = filter_var($_POST["message"], FILTER_SANITIZE_STRING);
Edit: After doing some digging i've found a thread that answers my first question and that the top code fragment will work. However i still don't know if i need to have this declared.
$('#myForm').ajaxForm();
