How to insert Captcha Code


Recommended Posts

Ok I am having an issue and can't think of a way to solve it as I only have basic PHP knowledge


I am trying to insert code from reCAPTCHA from google into my current form.  The problem is that it requires the method set to verify.php as I already have a form method of contact.php (this is the name of the page for the form)


I am pretty lost so if I can get a detailed explanation of how to get this to function properly I would really appreciate it.


The code that needs to be inserted in the form is:

<?php require_once('recaptchalib.php');
  $publickey = "your_public_key"; // you got this from the signup page
  echo recaptcha_get_html($publickey); ?>

The code that is supposed to be in verify.php and that I am hoping I can just inject into contact.php is:


  $privatekey = "your_private_key";
  $resp = recaptcha_check_answer ($privatekey,

  if (!$resp->is_valid) {
    // What happens when the CAPTCHA was entered incorrectly
    die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . ")");
  } else {
    // Your code here to handle a successful verification


And finally here is the contact.php page I have:


// Set email variables
$email_to = 'info@stay-seo.com';
$email_subject = 'Website Inquiry';

// Set required fields
$required_fields = array('fullname','email','comment','phone','address','city' );

// set error messages
$error_messages = array(
    'fullname' => '(X) Enter Your Name',
    'email' => '(X) Enter Your Email',
    'comment' => '(X) Enter a Message',
    'phone' => '(X) Enter Your Phone',
    'address' => '(X) Enter Your St Address',
    'city' => '(X) Enter Your City',

// Set form status
$form_complete = FALSE;

// configure validation array
$validation = array();

// check form submittal
if(!empty($_POST)) {
    // Sanitise POST array
    foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));
    // Loop into required fields and make sure they match our needs
    foreach($required_fields as $field) {        
        // the field has been submitted?
        if(!array_key_exists($field, $_POST)) array_push($validation, $field);
        // check there is information in the field?
        if($_POST[$field] == '') array_push($validation, $field);
        // validate the email address supplied
        if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
    // basic validation result
    if(count($validation) == 0) {
        // Prepare our content string
        $email_content = 'New Website Comment: ' . "\n\n";
        // simple email content
        foreach($_POST as $key => $value) {
            if($key != 'submit') $email_content .= $key . ': ' . $value . "\n";
        // if validation passed ok then send the email
        mail($email_to, $email_subject, $email_content);
        // Update form switch
        $form_complete = TRUE;

function validate_email_address($email = FALSE) {
    return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;

function remove_email_injection($field = FALSE) {
   return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
