reCaptcha integration problems

iVazanity · November 4, 2015

Hello im very new to PHP and I got a problem with integrating reCaptcha into my Form. Step one worked pretty good but im failing on Step 2 which is: If your users send the form with integrated reCAPTCHA, you will receive among other things, a string containing the name "G-recaptcha-response". If you want to find out if Google has verified the user in question, send a POST request with the following parameters:

URL: https://www.google.c.../api/siteverify

Secret (required) MY_SECRET_CODE Response (required) Value of 'g-recaptcha-response' remoteip The IP address of the end user

Heres my HTML Code:

<!DOCTYPE html>
<html >
  <head>
    <meta charset="UTF-8">
	<meta name="description" content="Kontaktieren Sie hier Mario Fracasso">
	<meta name="keywords" content="contact,kontakt,mario,fracasso,mariofracasso,schreiben,websites,offer">

			<link rel="stylesheet" href="css/style.css">
				<script src='https://www.google.com/recaptcha/api.js'></script>
  </head>

  <body>

    <div id="form-main">
  <div id="form-div">
	<h1>Contact - Mario </h1>
	<hr>
    <form action="php/form_process.php" method="post" class="form" id="form1">
      
      <p class="name">
        <input name="name" type="text" class="validate[required,custom[onlyLetter],length[0,100]] feedback-input" placeholder="First Name, Last Name" id="name" />
      </p>
      
      <p class="email">
        <input name="email" type="email" class="validate[required,custom[email]] feedback-input" id="email" placeholder="Email" />
      </p>
      
      <p class="text">
        <textarea name="text" class="validate[required,length[6,300]] feedback-input" id="comment" placeholder="Message"></textarea>
      </p>
      
<div class="g-recaptcha" data-sitekey="MY_CODE"></div>

      <div class="submit">

    </form>
<footer>

And heres my PHP Code:

<?php
 
if(isset($_POST['email'])) {

    $email_to = "MY-EMAIL";

    function died($error) {
 
        // your error code can go here
 
        echo "We are very sorry, but there were error(s) found with the form you submitted. ";
 
        echo "These errors appear below.<br /><br />";
 
        echo $error."<br /><br />";
 
        echo "Please go back and fix these errors.<br /><br />";
 
        die();
 
    }
 
     
 
    // validation expected data exists
 
    if(!isset($_POST['name']) ||
 
        !isset($_POST['email']) ||
 
        !isset($_POST['text'])) {
 
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
 
    }
 
     
 
    $name = $_POST['name']; // required
 
    $email_from = $_POST['email']; // required
 
 
    $text = $_POST['text']; // required
 
     
 
    $error_message = "";
 
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
 
  if(!preg_match($email_exp,$email_from)) {
 
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
 
  }
 
    $string_exp = "/^[A-Za-z .'-]+$/";
 
  if(!preg_match($string_exp,$name)) {
 
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
 
  }
 
  if(strlen($text) < 2) {
 
    $error_message .= 'The text you entered do not appear to be valid.<br />';
 
  }
 
  if(strlen($error_message) > 0) {
 
    died($error_message);
 
  }
 
    $email_message = "Form details below.\n\n";
 
     
 
    function clean_string($string) {
 
      $bad = array("content-type","bcc:","to:","cc:","href");
 
      return str_replace($bad,"",$string);
 
    }
 
     
 
    $email_message .= "First Name: ".clean_string($name)."\n";
 
 
    $email_message .= "Email: ".clean_string($email_from)."\n";
 
 
    $email_message .= "text: ".clean_string($text)."\n";
 
     
 
     
 
// create email headers
 
$headers = 'From: '.$email_from."\r\n".
 
'Reply-To: '.$email_from."\r\n" .
 
'X-Mailer: PHP/' . phpversion();
 
@mail($email_to, $email_subject, $email_message, $headers);  
 
?>
 
 
 
<!-- include your own success html here -->

So, heres my question: How do I implement this reCaptcha? Is there any solution? I hope you can help me - oh and hey, im sorry for my bad english.

As explained in googles recaptcha documentation for verifying the recaptcha response you need to send a POST request to https://www.google.com/recaptcha/api/siteverify containing both your google recaptcha's secret key and the g-recaptcha-response value in order for google to verify the users recpatcha value is valid when your form has been submitted.

To do this you would use curl, take a look at the post by printf's here for the code to do this. Note you will need to set the value of $key here

$key         = 'my key';

to your google recaptcha secrete key. And also replace

            echo 'Recaptha Result: ';


            var_dump ( $result['success'] );

With

            if($result['success'])
            {
                // YOUR CODE FOR SENDING THE EMAIL GOES HERE
            }

            {
                // YOUR CODE FOR SENDING THE EMAIL GOES HERE
            }

Thank you for your answer!

But if I paste this code into my Page, it gets me an error which is: Curl Error: ' . curl_error ( $curl_init ); } else { $result = json_decode ( $response, TRUE ); if($result['success']) { // YOUR CODE FOR SENDING THE EMAIL GOES HERE } } curl_close ( $curl_init ); } }

What sending code for the email is supposed to be here?

The Code:

        curl_setopt ( $curl_init, CURLOPT_SSL_VERIFYPEER, FALSE );

            }

        }


        curl_close ( $curl_init );

    }

}
<?

What did I do wrong?

And another question: Should I place this PHP code into my PHP file or just paste it into my html file?

Thanks advance for your help!

No the PHP code for verifying the recaptcha needs to go in the file where your form is being submitted to, which is php/form_process.php

Alright. Got ya.

The error message is gone. what about this part?

            if($result['success'])
            {
                // YOUR CODE FOR SENDING THE EMAIL GOES HERE
            }

As I said in the comment, replace it (the comment line, not the if statement) with your code that is processing/sending the email

This is so the email is only sent if the recpatcha response is valid.

iVazanity · November 4, 2015

It gets me another error in reCaptcha itself. Which is: ERROR: Invalid domain for site key

I've set the right domain..I thought.

Thanks for your help. It was my fault. lol.

It worked!

Hi,

I did that as you said but the refreshing"bug" is still there.. heres the part of the code:

      {

            $result = json_decode ( $response, TRUE );


            if($result['success'])
            {
            echo 'Recaptcha Result: ';


            var_dump ( $result['success'] );
            }

        }

Thank you so much for your help!

Ch0cu3r · November 4, 2015

I did that as you said

No you haven't I said this

As I said in the comment, replace it (the comment line, not the if statement) with your code that is processing/sending the email

You should know what part of your code is processing/sending the code if you have wrote the code

iVazanity · November 4, 2015

No you haven't I said this

You should know what part of your code is processing/sending the code if you have wrote the code

Alright I did that. Now it gives me the error Parse error: syntax error, unexpected end of file in /var/customers/webs/ni61032_1/mario/php/form_process.php on line 220

EDIT: If the Captcha isn't used the mail won't be sent! Hooray!

But if you use the captcha it doesn't send the email either.

I have re-organised your code/clean it up a little. Try

    die();
