Alright, so now you need to add back in the Google recaptcha code. Start by adding the below <script></script> block, in bold, to the form page, directly before the closing </body> tag, near the end of the page.
Add YOUR RECAPTCHA SITE KEY where indicated in the code. You need to keep the site key wrapped in quotes ' ' in the second instance, as shown below:
<script src="https://www.google.com/recaptcha/api.js?render=YOUR RECAPTCHA SITE KEY"></script>
<script>
grecaptcha.ready(function() {
grecaptcha.execute('YOUR RECAPTCHA SITE KEY' , {action: 'homepage'}).then(function(token) {
document.getElementById('token').value = token;
})
})
</script>
Now add an input field to your form directly before the closing </form> tag:
<input type="hidden" id="token" name="token">
</form>
This form field will be automatically populated with your site key by the javascript you added.
Now you have to add the recaptcha code to the 'ContactMail-new.php' page. The code in bold below (apart from the opening and closing <?php ?> tags) is what should already exit in your php page, so you just need to copy and add the code which is NOT in bold, so every thing looks like below.
Add your RECAPTCHA SECRECT KEY where indicated in the php code below (keep the ' ' around the secret key):
If successful your 'pages/contact_sent.html' page will be included in the 'ContactMail-new.php' page. You need to create a similar page for a failed result - 'pages/contact_failed.html' and put some message in that file plus a button back to the page the form is located on.
<?php
//set recaptcha url/secret-key/response
$recapture_url = 'https://www.google.com/recaptcha/api/siteverify';
$recaptcha_secret = 'YOUR RECAPTCHA SECRECT KEY';
$recaptcha_response = $_POST['token'];
//send information to recaptcha url
$recaptcha = file_get_contents($recapture_url . '?secret=' . $recaptcha_secret . '&response=' . $recaptcha_response);
$recaptcha = json_decode($recaptcha);
//check if recaptcha has been successful
if($recaptcha->success==true) {
if($recaptcha->score >= 0.5) {
// if recaptcha is successful and score is equal or more than 0.5 process the form information
$name = htmlspecialchars($_POST['Name']);
$email = htmlspecialchars($_POST['email']);
$message = htmlspecialchars($_POST['message']);
if(empty($name) || empty($email) || empty($message)) {
$error = true;
$status = "Failed";
}
elseif(filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
$error = true;
$status = "Failed";
}
// if no form errors are set then send the form information to the email address
if(!isset($error)) {
$formcontent=" From: $name \n Email: $email \n Message: $message";
$recipient = "RECIPIENT EMAIL ADDRESS";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
$status = "Successful";
}
}
// if recaptcha fails set a status
else {
$status = "Failed";
}
}
// if status is successful then include the contact_sent.html page
if($status === "Successful") {
include('pages/contact_sent.html');
}
else {
// if status is failed then include the contact_failed.html page
include('pages/contact_failed.html');
}
?>
Thats it!
