Troubleshooting AJAX form submission

I'm scratching my head with this one at the moment - if any of you could help that'd be amazing. I have a site which uses AJAX to submit a contact form after a simple validation. All goes well, and the site acts as if the email has sent, but I'm not receiving any emails (yep I've triple checked, it's the right email address).
Here's what I'm working with:
HTML / PHP
<script type="text/javascript" language="javascript" src="js/contact.js"></script>
...
<section id="contact">
<span class="contact_results"></span>
<div class="form">
<input type="text" name="name" id="contactname" required value="<? echo $user_name ?>" placeholder="Your Name:" autocomplete="off">
<input type="email" name="email" id="email" required value="<? echo $email ?>" placeholder="Your E-Mail Address:" autocomplete="off">
<input type="phone" name="phone" id="phone" value="<? echo $phone ?>" placeholder="Your Telephone Number:" autocomplete="off">
<textarea name="message" id="message" required placeholder="Your Message:"><? echo $message ?></textarea>
<button type="submit" name="submit" id="contactbutton">Submit Form</button>
</div>
</section>
Contact.js
$(function() {
$("#contact button").click(function() {
var proceed = true;
//simple validation at client's end
//loop through each field and we simply change border color to red for invalid fields
$("#contact input[required=true], #contact textarea[required=true]").each(function(){
$(this).css('border-color','#EEE');
if(!$.trim($(this).val())){ //if this field is empty
$(this).css('border-color','#FC0'); //change border color to red
proceed = false; //set do not proceed flag
}
//check invalid email
var email_reg = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
if($(this).attr("type")=="email" && !email_reg.test($.trim($(this).val()))){
$(this).css('border-color','#FC0'); //change border color to red
proceed = false; //set do not proceed flag
}
});
if(proceed) //everything looks good! proceed...
{
//get input field values data to be sent to server
post_data = {
'user_name' : $('input[name=name]').val(),
'user_email' : $('input[name=email]').val(),
'user_phone' : $('input[name=phone]').val(),
'msg' : $('textarea[name=message]').val()
};
//Ajax post data to server
$.post('contact_sendform.php', post_data, function(response){
if(response.type == 'error'){ //load json data from server and output message
output = '<span class="error">'+response.text+'</span>';
}else{
output = '<span class="success">'+response.text+'</span>';
//reset values in all input fields
$("#contact input[required=true], #contact textarea[required=true]").val('');
$(".form").fadeOut(400); //hide form after success
}
$("#contact .contact_results").hide().html(output).slideDown(400);
}, 'json');
}
});
//reset previously set border colors and hide all message on .keyup()
$("#contact input[required=true], #contact textarea[required=true]").keyup(function() {
$(this).css('border-color','');
$("#result").slideUp();
});
});
contact_sendform.php
<?php
if($_POST)
{
$to_email = "xxxxxxxx#hotmail.com";
//check if its an ajax request, exit if not
if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
$output = json_encode(array( //create JSON data
'type'=>'error',
'text' => 'Sorry Request must be Ajax POST'
));
die($output); //exit script outputting json data
}
//Sanitize input data using PHP filter_var().
$user_name = filter_var($_POST["user_name"], FILTER_SANITIZE_STRING);
$user_email = filter_var($_POST["user_email"], FILTER_SANITIZE_EMAIL);
$user_phone = filter_var($_POST["user_phone"], FILTER_SANITIZE_NUMBER_INT);
$message = filter_var($_POST["msg"], FILTER_SANITIZE_STRING);
//additional php validation
if(strlen($user_name)<3){ // If length is less than 4 it will output JSON error.
$output = json_encode(array('type'=>'error', 'text' => 'Name is too short or empty!'));
die($output);
}
if(!filter_var($user_email, FILTER_VALIDATE_EMAIL)){ //email validation
$output = json_encode(array('type'=>'error', 'text' => 'Please enter a valid email!'));
die($output);
}
if(strlen($message)<3){ //check emtpy message
$output = json_encode(array('type'=>'error', 'text' => 'Too short message! Please enter something.'));
die($output);
}
//email body
$message_body = $message."\r\n\r\n-".$user_name."\r\nEmail : ".$user_email."\r\nPhone Number : ". $user_phone ;
// Set Subject
$subject = "Ian! You've got a new message from ".$user_name;
//proceed with PHP email.
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: '.$user_email."\r\n".
'Reply-To: '.$user_email."\r\n" .
'X-Mailer: PHP/' . phpversion();
$send_mail = mail($to_email, $subject, $message_body, $headers);
if(!$send_mail)
{
//If mail couldn't be sent output error. Check your PHP email configuration (if it ever happens)
$output = json_encode(array('type'=>'error', 'text' => 'Could not send mail! Please check your PHP mail configuration.'));
die($output);
}else{
$userArray = explode(' ', trim($user_name));
$output = json_encode(array('type'=>'message', 'text' => 'Thanks for getting in touch, '.$userArray[0] .'!'));
die($output);
}
}
?>
As I said - when the form is submitted with the correct data, it displays the confirmation message which only fires when $sendMail works - so I'm at a loss as to what's going wrong. Any insight or help would be majorly appreciated - thanks! :)

send form via AJAX in jQuery then save in MySQL but doesn't work

as title, I am a beginner about website design.
Please never mind if I ask a stupid question.
while i send the form, it didnt work.
here is html:
<form id="form1" name="form1" action="toSQL.php" method="POST" accept-charset="utf-8">
<input type="text" name="Cliname" id="textfield" maxlength = "10" />
<textarea name="message" id="message" rows="3" maxlength = "20" ></textarea>
<input type="submit" value="submit" id="submit" />
</form>
<div class="alert"></div>
and here is js:
<script type="text/javascript">
$(document).ready(function() {
var form = $(this) ;
var submited = $('#submit') ;
var alerted = $('.alert') ;
form.on( 'submit', this, (function(event) {
event.preventDefault();
if ( $.trim($form.find('input[name="Cliname"]').val()) == "" || $.trim($form.find('input[name="message"]').val()) == "" ) {
alert( "please enter!!" ) ;
return ;
}
else {
$.ajax({
url: 'toSQL.php', // form action url
type: 'POST', // form submit method get/post
dataType: 'html', // request type html/json/xml
data: form.serialize(), // serialize form data
beforeSend: function() {
alerted.fadeOut();
},
success: function(data) {
alerted.html(data).fadeIn(); // fade in response data
form.trigger('reset'); // reset form
},
error: function(e) {
console.log(e)
}
});
}
}));
});
</script>
server side php:
<?php
if( isset( $_SERVER['HTTP_X_REQUESTED_WITH'] ) ){
if (isset($_POST['Cliname']) AND isset($_POST['message'])) {
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$message = filter_var($_POST['message'], FILTER_SANITIZE_STRING);
if (send($name, $message)) {
echo 'Message sent!';
} else {
echo 'Message couldn\'t sent!';
}
}
else {
echo 'All Fields are required';
}
return;
}
function send( $name, $message ) {
$time = date("Y-m-d H:i:s");
$mysqlConnection=mysql_connect("localhost", 'root', '') or die("connect error!");
mysql_select_db('test') or die ("db error!");
$queryStr="INSERT INTO fortest (time, message, name)
VALUES ( '$time', '$message', '$name')";
mysql_query($queryStr,$mysqlConnection) or die(mysql_error());
return true ;
}
?>
here is the website i reference : http://www.w3bees.com/2013/08/submit-form-without-page-refresh-with.html
Did i miss something?

As a couple people have mentioned already, you are trying to serialize your entire dom object, which isn't going to work. Change it to var form = $("#form1") and it should work.
I recommend you open the webpage in chrome dev tools and click the network tab, click preserve log and then submit the form. When it is submitted you'll see the full headers that were sent to the server and can verify it works correctly to help narrow down the problem

AJAX not returning result from php

I am trying to learn from an example from online,for a login form with php and jquery and i am using the exactly the same example, but for some reason the AJAX isnt getting anything back but redirecting my to another php.
Here is a link of what i had been trying and the problem.
http://rentaid.info/Bootstraptest/testlogin.html
It supposed to get the result and display it back on the same page, but it is redirecting me to another blank php with the result on it.
Thanks for your time, i provided all the codes that i have, i hope the question isnt too stupid.
HTML code:
<!DOCTYPE HTML>
<html>
<head>
</head>
<body>
<form id= "loginform" class="form-horizontal" action='http://rentaid.info/Bootstraptest/agentlogin.php' method='POST'>
<p id="result"></p>
<!-- Sign In Form -->
<input required="" id="userid" name="username" type="text" class="form-control" placeholder="Registered Email" class="input-medium" required="">
<input required="" id="passwordinput" name="password" class="form-control" type="password" placeholder="Password" class="input-medium">
<!-- Button -->
<button id="signinbutton" name="signin" class="btn btn-success" style="width:100px;">Sign In</button>
</form>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javasript" src="http://rentaid.info/Bootstraptest/test.js"></script>
</body>
</html>
Javascript
$("button#signinbutton").click(function() {
if ($("#username").val() == "" || $("#password").val() == "") {
$("p#result).html("Please enter both userna");
} else {
$.post($("#loginform").attr("action"), $("#loginform:input").serializeArray(), function(data) {
$("p#result").html(data);
});
$("#loginform").submit(function() {
return false;
});
}
});
php
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
ob_start();
session_start();
include 'connect.php';
//get form data
$username = addslashes(strip_tags($_POST['username']));
$password = addslashes(strip_tags($_POST['password']));
$password1 = mysqli_real_escape_string($con, $password);
$username = mysqli_real_escape_string($con, $username);
if (!$username || !$password) {
$no = "Please enter name and password";
echo ($no);
} else {
//log in
$login = mysqli_query($con, "SELECT * FROM Agent WHERE username='$username'")or die(mysqli_error());
if (mysqli_num_rows($login) == 0)
echo "No such user";
else {
while ($login_row = mysqli_fetch_assoc($login)) {
//get database password
$password_db = $login_row['password'];
//encrypt form password
$password1 = md5($password1);
//check password
if ($password1 != $password_db)
echo "Incorrect Password";
else {
//assign session
$_SESSION['username'] = $username;
$_SESSION['password'] = $password1;
header("Location: http://rentaid.info/Bootstraptest/aboutus.html");
}
}
}
}
?>
Edit
$("button#signinbutton").click(function(){
if($("#username").val() ==""||$("#password").val()=="")
$("p#result).html("Please enter both userna");
else
$.post ($("#loginform").attr("action"),
$("#loginform:input").serializeArray(),
function(data) {
$("p#result).html(data); });
});
$("#loginform").submit(function(){
return false;
});

First of all, Remove :-
header("Location: http://rentaid.info/Bootstraptest/aboutus.html");
and if you want to display the data, echo username and password.
$_SESSION['username'] = $username;
$_SESSION['password'] = $password1;
echo $username."<br>".;
echo $password1;

The reason you are being redirected is that you are also calling $.submit. The classic form submit will redirect you to a new page, which is exactly what you don't want when you're using AJAX. If you remove this call:
$("#loginform").submit(function() {
return false;
});
you probably should have working solution. If not, let me know :)

Modify your javascript section so that
$("button#signinbutton").click(function() {
if ($("#username").val() == "" || $("#password").val() == "") {
$("p#result).html("Please enter both userna");
} else {
$.post($("#loginform").attr("action"), $("#loginform:input").serializeArray(), function(data) {
$("p#result").html(data);
});
}
});
$("#loginform").submit(function() {
return false;
});
is outside the function call.
