Ajax Jquery and PHP form validation, 404 error

I am trying to process a form with ajax, jquery and php and I am getting a 404 error, searched before I posted but I did not find the answer to help me fix my problem, this is the .js file :
$(document).ready(function() {
$('form #error-message').hide();
$('#submit').on('click' , function(e) {
e.preventDefault();
var valid = '';
var required = " is required";
var fname = $('form #fname').val();
var lname = $('form #fname').val();
var dbirth = $('form #dbirth').val();
var adress1 = $('form #adress1').val();
if (fname = '' || fname.lenght <= 2) {
valid += '<p><span>X</span> Full Name ' + required + '</p>';
}
if (lname = '' || lname.lenght <= 2) {
valid += '<p><span>X</span> Full Name ' + required + '</p>';
}
if (dbirth = '' || dbirth.lenght <= 2) {
valid += '<p><span>X</span> Full Name ' + required + '</p>';
}
if (adress1 = '' || adress1.lenght <= 5) {
valid += '<p><span>X</span> Full Name ' + required + '</p>';
}
if(valid != '') {
$('form #error-message').removeClass().addClass('warning')
.html('<h1>Please complete all the fields</h1>' + valid);
} else {
var contactData = $( 'form' ).serialize();
console.log(contactData);
$.ajax({
type: 'POST',
url: 'ajaxform/process.php',
data: contactData,
success: function() {
$('#error-message').removeClass().addClass('success')
.html("<h1>Thank you for contacting me. I will reply as soon as i can!</h1>");
},
error: function() {
$('#error-message').removeClass().addClass('alert-error')
.html("An error has occured. Please try again later")
},
complete: function() {
$('form')[0].reset();
}
});
}
});
});
and this is the .php file :
<?php
sleep(1);
$to = 'yourcompany#gmail.com';
$subject = 'My form contact';
if( isset($_POST['fname']) && isset($_POST['lname']) && isset($_POST['dbirth']) && isset($_POST['adress1'])) {
$fname = trim($_POST['fname']);
$lname = trim($_POST['lname']);
$sdate = trim($_POST['dbirth']);
$adress1 = trim($_POST['adress1']);
if(!empty($fname) && !empty($lname) && !empty($dbirth) && !empty($adress1)) {
$full_name = $fname . " " . $lname;
$body = $full_name . "\n" . $adress1;
$headers = "From {$full_name} " . $dbirth;
mail($to, $subject, $body, $headers);
}
} else {
header('location: ../index.html');
}
?>

I suggest you phpmailer. You can download it at this link.
<?php
require_once('class.phpmailer.php');
sleep(1);
$to = 'yourcompany#gmail.com';
$subject = 'My form contact';
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 1; // will send erros and messages
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'tls';
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; //Gmail smtp port
$mail->Username = "youremail#gmail.com";
$mail->Password = "yourpassword";
$mail->SetFrom($headers);
$mail->Subject = $subject;
if( isset($_POST['fname']) && isset($_POST['lname']) && isset($_POST['dbirth']) && isset($_POST['adress1'])) {
$fname = trim($_POST['fname']);
$lname = trim($_POST['lname']);
$sdate = trim($_POST['dbirth']);
$adress1 = trim($_POST['adress1']);
if(!empty($fname) && !empty($lname) && !empty($dbirth) && !empty($adress1)) {
$full_name = $fname . " " . $lname;
$body = $full_name . "\n" . $adress1;
$headers = "From {$full_name} " . $dbirth;
$mail->Body = $body;
$mail->AddAddress($to);
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
header('location: ../index.html');
}
}
}
?>

Keep input field values when form fails

I have a pretty basic form that uses php to send an email and do some basic validation. It's also using ajax so the page doesn't have to reload on submission. The form's been working well, but if someone submits the form and it fails validation, all form fields are reset.
How would I go about keeping the values a user has entered when the form fails? I have a feeling it'll have something to do with my javascript file, but I'm a newb with javascript and not really sure what direction to go. Can anyone help?
Here's my form.html:
<div id="response"></div>
<div class="form-group">
<label for="name">Your Name:</label>
<input type="text" name="name" id="name" class="form-control" placeholder="Jesse James">
</div>
<div class="form-group">
<label for="email">Email:</label>
<input type="email" name="email" id="email" class="form-control" placeholder="howCan#weReachYou.com">
</div>
<div class="form-group">
<label for="phone">Phone:</label>
<input type="tel" name="phone" id="phone" class="form-control" placeholder="734-968-4509">
</div>
<div class="form-group">
<label for="message">Message</label>
<textarea class="form-control" id="message" name="message" rows="6" placeholder="How can we help...?"></textarea>
</div>
<button type="submit" name="submit" id="submit" class="btn btn-default">Send It</button>
<input type="hidden" name="honeypot" id="honeypot" value="http://">
<input type="hidden" name="humancheck" id="humanCheck" class="clear" value="">
and the ajax_sumit.js:
$(document).ready(function() {
$('#contact input:submit').click(function() {
$('#contact form').attr('action', 'http://' + document.domain + '/php/feedback.php');
$('#contact form').submit();

I really appreciate any help! :-)

I think the easiest way is to store the values in a session and destroy that after processing.

Verify reCaptcha google in FrontEnd php ajax jquery

I'm trying to create a form with reCaptcha.
Although I'm not an expert with javascript and ajax I succeed to cretae form and verify it with ajax before submit but when I added reCaptcha to my form I couldn't verify it FrontEnd. (In Backend, it works very well and the form is sent only if all field and captcha are all correctly filled)
I want to create something to alert user when he didn't fill the reCaptcha.
Below my code:

What I want is:
To alert user who missed to check captcha exactly like I did to verify other field before submit. I want to verify all my form before submitting ( In frontEnd). and the code above check all field in frontEnd except of captcha.
How can I verify if captcha is checked or no in frontEnd.
Any info that allow me to keep coding.

I find the solution, if We want to verify reCaptcha before submitting we have to add this simple code in submit (It will allow us to know if the reCaptcha is cheked or no):
var msg_captch = " You need to check Captcha";
var captch = jQuery('#g-recaptcha-response').val();
if(!captch)
{
$("#msg_captch").html(msg_captch);
}
Please see the code above to know what is 'msg_captch'

JavaScript Ajax function returning error with status code 'OK'

I do not understand why this ajax request is returning an error even though the error status is OK (200), any thoughts? It seems like I am missing something very obvious but I have been tearing myself apart trying to find an answer! I am new to ajax and therefore have little experience with it! Thanks for the help.
This is my ajax request:
var dataString = $('#cform').serialize();
$.ajax({
type: "POST",
url: 'contact.php',
data: dataString,
dataType: 'json',
success: function (data) {
if (data.success == 0) {
var errors = '<ul><li>';
if (data.name_msg != '')
errors += data.name_msg + '</li>';
if (data.email_msg != '')
errors += '<li>' + data.email_msg + '</li>';
if (data.godaddyemail_msg != '')
errors += '<li>' + data.godaddyemail_msg + '</li>';
if (data.godaddyuser_msg != '')
errors += '<li>' + data.godaddyuser_msg + '</li>';
$("div#output").removeClass('alert-success').addClass('alert-error').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p> Could not complete your request. See the errors below!' + errors + '</p>');
}
else if (data.success == 1) {
$("div#output").removeClass('alert-error').addClass('alert-success').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p>You message has been sent successfully!</p>');
}
},
error: function (error) {
$("div#output").removeClass('alert-success').addClass('alert-error').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p> Could not complete your request. The Function returned an error!</p>' + error.statusText); }
});
return false;
}
This is contact.php (where the request is sent to):
<?php

That is because you have two undefined variables on your send_email() function.
Here you have this if statement..
if($message=='message')$message=''; // $message is not available inside this function.
and here
mail($send_email_to, $subject, $message,$headers); //$subject is also undefined.

$.post not returning data on one server, does on another

I have a simple contact form that uses js to post via php, and read the response to do some simple appending/css to list errors and a successful send. It normally pops up an error on the field if you have left it blank / if it is not a proper address, and when succesful, removes the form and appends a thank you note.
The problem is, while it works perfectly on my own server, it sends the mail without giving error/success on the production
I'm not using cross-domain requests, and I have tried disabling compression to no avail. Caching is enabled, though it should not matter.
The javascript
$('.contact-us').submit(function(e) {
e.preventDefault();
$('.contact-us input, .contact-us textarea').removeAttr('style');
$('.error').remove();
var postdata = $('.contact-us').serialize();
$.ajax({
type: 'POST',
url: 'contact2.php',
data: postdata,
dataType: 'json',
success: function(returned_data) {
var j = 0;
var submit_ok = true;
$.each(returned_data, function(key, value) {
if(value != '') {
$('.contact-us .' + key).attr('style', 'border-color: #e67632; -moz-box-shadow: none; -webkit-box-shadow: none; box-shadow: none;');
$('.contact-us .' + key).focus();
$('.contact-us').append('<div class="error"> ' + value + '</div>');
$('.error').css('top', (j*52) + 'px');
$('.error').fadeIn('slow');
submit_ok = false;
return false;
}
j++;
});
if(submit_ok) {
$('.contact-us').append('<p style="display: none;">Thanks for contacting us! We will get back to you very soon.</p>');
$('.contact-us input, .contact-us textarea, .contact-us button').remove();
$('.contact-us p').fadeIn('slow');
}
}
});
});
The php
<?php
