jQuery:

$(document).ready(function($) {
	$("#modal_contact").wrap("<form id='v_form'></form>");
	$("#contact_us_fixed").click(function () {
	   $("#v_form, #modal_contact").fadeIn('slow');
	});
	$("#close_qc").click(function () {
	   $("#v_form").hide();
	});
});

function validate_form(){

jQuery.fn.pVal = function(){
    var jQuerythis = jQuery(this),
        val = jQuerythis.eq(0).val();
    if(val == jQuerythis.attr('placeholder'))
        return '';
    else
        return val;
}

		var regName=/([a-zA-Z\-\_]{2,30})/;
		var regPhone=/([0-9\+\- ]{10,20})/;
		var regEmail=/[0-9a-z_]+@[0-9a-z_^.]+.[a-z]{2,3}/i;
		var regEmpty=/([^\s])/;
		
		var full_name=$('#cname').val();
		var email=$("#cmail").val();
		var phone=$("#cphone").val();
		var comments=$("#cquest").val();
		
		if(
		regEmpty.test(full_name) &&
		regEmail.test(email) &&
		regEmpty.test(comments)
		) {
		var data = {
			full_name: full_name,
			email: email,
			phone: phone,
			comments: comments
		};
		$.ajax({
			type: "POST",
			url: "csent.php",
			dataType: "json",
			data: data,
			success: function(){
				console.log('ok');
				return;
			},
			error: function(e) {
			console.log('ok-error');
				return;
			}
		});
		$('.all_inputs').hide();
		$('#msgg').html("Message is successfully sent!").fadeIn('slow');
		setTimeout(function(){
			$('#v_form').trigger('reset');
			$('#msgg').hide().html("");
			$('#v_form').hide();
			$('.all_inputs').show();
		},4000);
		$('.error').fadeOut(200).hide();
		} else {
		console.log('error');
		$('.error').fadeIn(200);
		setTimeout(function(){
			$('.error').fadeOut(200);
		},3000);
			if(!regEmpty.test(full_name)) {
				$('#cname').addClass('alert-error');
				setTimeout(function(){$('#cname').removeClass('alert-error');},3000);
			}
			if(!regEmail.test(email)) {
				$('#cmail').addClass('alert-error');
				setTimeout(function(){$('#cmail').removeClass('alert-error');},3000);
			}
			if(!regEmpty.test(comments)) {
				$('#cquest').addClass('alert-error');
				setTimeout(function(){$('#cquest').removeClass('alert-error');},3000);
			}
		}
	  }

и сам php-скрипт отправки почты при успешной валидации формы:

if ($_SERVER['REQUEST_METHOD']=='POST') {
if(
	!empty($_POST['full_name']) &&
	!empty($_POST['email']) &&
	!empty($_POST['comments'])
	){

$full_name = strip_tags($_POST['full_name']);
$email = strip_tags($_POST['email']);
$phone = strip_tags($_POST['phone']);
$comments = strip_tags($_POST['comments']);

$date = date('j.m.Y G:i');
$ref = $_SERVER['HTTP_REFERER'];

$header="Contact Us Widget";
$contactHeaders= "MIME-Version: 1.0\r\n";
$contactHeaders .= "Content-type: text/html; charset=iso-8859-1\r\n";
$contactHeaders .= "From: Contact Us Widget <noreplay@mail.com>";
$contact="<h2>Contact Us Widget</h2>
Full Name: $full_name<br/>
Email: $email<br/>
Phone: $phone<br/>
Comments: $comments<br/><br/>
DATE: <b>$date</b><br/>
REF_URL: $ref";
$res=mail("your@mail.com",$header,$contact,$contactHeaders);

header('Content-Type: application/json');
echo json_encode(array('response'=>'success'));
exit;
} } else { }

кстати, про выравнивание формы по центру экрана:

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  margin-top: -50px;
  margin-left: -100px;
}

Марджины должны быть на половину меньше высоты и ширины блока. top и left всегда должен быть 50%. Этот способ описан здесь. Если ширина и высота блока неизвестна, то можно сделать так:

$(document).ready(function(e) {
    var win = $('.window');
    win.css({
        'margin-top':'-' + (win.height() / 2) + 'px',
        'margin-left':'-' + (win.width() / 2) + 'px'
        });
});
