I should solve a problem with a contact form and I don't know where to put my hands anymore.
I have a form in HTML, then a validation in JS and finally an email sending in PHP.
The form data are: Name, Clinic, Email, Phone, Address and Valutation.
In the email I receive the data are:
Name: name entered in the form
Email: email entered in the form
Clinic: undefined
Phone: undefined
Address: undefined
Valutation: undefined
This is the code (HTML + JS):
// JavaScript Document
$(document).ready(function() {
"use strict";
$(".contact-form").submit(function(e) {
e.preventDefault();
var name = $(".name");
var email = $(".email");
var clinic = $(".clinic");
var phone = $(".phone");
var address = $(".address");
var valutation = $(".valutation");
var subject = $(".subject");
var msg = $(".message");
var flag = false;
if (name.val() == "") {
name.closest(".form-control").addClass("error");
name.focus();
flag = false;
return false;
} else {
name.closest(".form-control").removeClass("error").addClass("success");
}
if (email.val() == "") {
email.closest(".form-control").addClass("error");
email.focus();
flag = false;
return false;
} else {
email.closest(".form-control").removeClass("error").addClass("success");
}
var dataString = "name=" + name.val() + "&email=" + email.val() + "&subject=" + subject.val() + "&msg=" + msg.val() + "&clinic=" + clinic.val() + "&phone=" + phone.val() + "&address=" + address.val() + "&valutation=" + valutation.val();
$(".loading").fadeIn("slow").html("Loading...");
$.ajax({
type: "POST",
data: dataString,
url: "php/contactForm.php",
cache: false,
success: function(d) {
$(".form-control").removeClass("success");
if (d == 'success') // Message Sent? Show the 'Thank You' message and hide the form
$('.loading').fadeIn('slow').html('<font color="#48af4b">Mail sent Successfully.</font>').delay(3000).fadeOut('slow');
else
$('.loading').fadeIn('slow').html('<font color="#ff5607">Mail not sent.</font>').delay(3000).fadeOut('slow');
}
});
return false;
});
$("#reset").on('click', function() {
$(".form-control").removeClass("success").removeClass("error");
});
})
<div class="row justify-content-center">
<div class="col-lg-10 col-xl-8">
<div class="form-holder">
<form class="row contact-form" method="POST" action="php/contactForm.php" id="contactForm">

<div class="col-lg-12 contact-form-msg">

</div>
</form>
</div>

</div>
And this is the PHP code:
<?php
$name = $_REQUEST["name"];
$email = $_REQUEST["email"];
$clinic = $_REQUEST["clinic"];
$phone = $_REQUEST["phone"];
$address = $_REQUEST["address"];
$valutation = $_REQUEST["valutation"];
$to = "myemail@email.com";
if (isset($email) && isset($name)) {
$email_subject = "Request to access to the Price List";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "From: ".$name." <".$email.">\r\n"."Reply-To: ".$email."\r\n" ;
$msg = "From: $name<br/> Email: $email <br/> Clinic: $clinic <br/> Phone: $phone <br/> Address: $address <br/> Valutation: $valutation";
$mail = mail($to, $email_subject, $msg, $headers);
if ($mail) {
echo 'success';
} else {
echo 'failed';
}
}
?>
Your issue is your selectors. You only use classes name
and email
for all your inputs.
<input type="text" name="phone" class="form-control name" ...>
should actually be:
<input type="text" name="phone" class="form-control phone" ...>
and so on for all the other inputs. Change your selectors to the appropriate classNames.
Also, never just use i.e: $(".name");
, $(".email");
etc. as your selectors. As you know already $(".name");
will get every class="name"
in your document. Same goes for all the other selectors. Instead, use the second argument (ParentElement) that will limit the search only to the children elements of the provided parent:
var name = $(".name", this);
or rather, use attribute selectors like:
var clinic = $(`[name="clinic"]`, this);
IMPORTANT NOTE about validation:
never trust the client.
JS validation should be used minimally, just as a UX tool to help, inform the user about basic errors/typos. The real validation, as well as all the related error responses, should be handled on the backend side.
Currently your PHP seems quite open to XSS attacks.
You don't need a HTML <form>
in order to send data to the server. All it takes to an attacker is to find your route/path (usually exposed via the form's action
attribute), take a look at the names in the source and manually construct a HTTP request, and send dangerous arbitrary data to your server. Just so you keep in mind.
