I have this contact form, that functions. However, I am concerned because you are able to directly access "sendmessage.php" and it emails a blank message to my inbox. I am having trouble addressing the issue. Should I restrict the file to ajax requests? If so, how?

 

You can see it in action at tylerabell.com

 

 

HTML file

<!-- Trigger Link -->
<a class="modalbox last" href="#inline">Contact</a></div>

<!-- hidden inline form -->
<div id="inline">
<form id="contact" name="contact" action="#" method="post">
<div id="your_name">
<label for="name">Name</label>
<input type="name" id="name" name="name" class="txt">
</div>
<div id="your_email">
<label for="email">Email</label>
<input type="email" id="email" name="email" class="txt">
</div>
<div id="your_message">
<label for="message">Message</label>
<textarea id="message" name="message" class="txtarea"></textarea>
</div>
<button id="send">Send Message</button>
</form>
</div>

 

Script using jQuery:

// basic fancybox setup
function validateEmail(email) {
var reg = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return reg.test(email);
}


$(document).ready(function() {
$(".modalbox").fancybox();
$("#contact").submit(function() { return false; });



$("#send").on("click", function(){
var emailval = $("#email").val();
var messageval = $("#message").val();
var messagelen = messageval.length;
var nameval = $("#name").val();
var namelen = nameval.length;
var mailvalid = validateEmail(emailval);

if(mailvalid == false) {
$("#email").addClass("error");
}
else if(mailvalid == true){
$("#email").removeClass("error");
}

if(messagelen < 4) {
$("#message").addClass("error");
}
else if(messagelen >= 4){
$("#message").removeClass("error");
}


if(namelen < 2) {
$("#name").addClass("error");
}
else if(namelen >= 2){
$("#name").removeClass("error");
}

if(mailvalid == true && messagelen >= 4 && namelen >= 2) {
// if both validate we attempt to send the e-mail
// first we hide the submit btn so the user doesnt click twice
$("#send").replaceWith("<p>Sending your message...</p>");

$.ajax({
 type: 'POST',
 url: 'sendmessage.php',
 data: $("#contact").serialize(),
 success: function(data) {
 if(data == "true") {
 $("#contact").fadeOut("slow", function(){
 $(this).before("<p>Success, Your message has been sent.</p>");
 setTimeout("$.fancybox.close()", 1000);
 });
 }
 }
});
}
});
});

A http request made by ajax is no different from any other http request, even one made by a search engine spider indexing your site.

 

Your server-side php form processing code must check if a form was submitted at all and it must filter/validate all the submitted data before it uses it.

Oh gotcha, I have used a different script in the past however there is a php error when you directly access the php file.

 

<?php
if( isset($_POST) ){

$recipient   = "email@domain.com";
$msgsubject   = "Contact Form Submission";

//form validation vars
$formok = true;
$errors = array();

//sumbission data
$ipaddress = get_ip_address();
$host      = gethostbyaddr($_SERVER['REMOTE_ADDR']);
$agent     = $_SERVER['HTTP_USER_AGENT'];
$date = date('l, F, d Y');
$time = date('g:i:s a');

//form data
$name = $_POST['name'];
$email = $_POST['email'];
$telephone = $_POST['telephone'];
$message = $_POST['message'];

//validate form data

//validate name is not empty
if(empty($name)){
 $formok = false;
 $errors[] = "You have not entered a name";
}

//validate email address is not empty
if(empty($email)){
 $formok = false;
 $errors[] = "You have not entered an email address";
//validate email address is valid
}elseif(!filter_var($email, FILTER_VALIDATE_EMAIL)){
 $formok = false;
 $errors[] = "You have not entered a valid email address";
}

//validate message is not empty
if(empty($message)){
 $formok = false;
 $errors[] = "You have not entered a message";
}
//validate message is greater than 20 charcters
elseif(strlen($message) < 20){
 $formok = false;
 $errors[] = "Your message must be greater than 20 characters";
}

//send email if all is ok
if($formok){
 $headers = "From: {$email}" . "\r\n";
 $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

try changing the 

if(isset($_POST)){

to somthing like this : 

if($_SERVER['REQUEST_METHOD'] != "POST" || !isset($_POST['email']) || !isset($_POST['message'])){
header('Location: yourFormPage.php');
else{
//your email script
}

obviously you will need to change the "yourFormPage.php" to the actual form page name and location.

 

You should always check if things like $_POST / $_GET are not there, this avoids any udefined refference warnings on the page which can happen by checking if they are.
