Contact Form 7: reCaptcha Issue

I’m using the latest version Contact Form 7.

When I added recaptcha field to the form, I got error, couldn’t send email. But, when I removed recaptcha field, the form worked fine.

I checked by adding the following code after the line 81 in modules\recaptcha.php:

var_dump($response)

and got the result:

object(WP_Error)#5494 (2) {
  ["errors"]=>
  array(1) {
    ["http_request_failed"]=>
    array(1) {
      [0]=>
      string(35) "cURL error 6: name lookup timed out"
    }
  }
  ["error_data"]=>
  array(0) {
  }
}

So, I tried to solve this issue by replaced the “verify” function with the following functions:

public function verify( $response_token ) {
		$is_human = false;

		if ( empty( $response_token ) ) {
			return $is_human;
		}

		$url = self::VERIFY_URL;
        $sitekey = $this->get_sitekey();
        $secret = $this->get_secret( $sitekey );
        $response = file_get_contents($url ."?secret=" . $secret . "&response=" . $response_token . "&remoteip=" .$_SERVER['REMOTE_ADDR']);

        if ( 200 != $this->parseHeaders($http_response_header)["reponse_code"] ) {
            return $is_human;
        }
		
		$response = json_decode( $response, true );

		$is_human = isset( $response['success'] ) && true == $response['success'];
		return $is_human;
	}
	
	private	function parseHeaders( $headers ) {
        $head = array();
        foreach( $headers as $k=>$v )
        {
            $t = explode( ':', $v, 2 );
            if( isset( $t[1] ) )
                $head[ trim($t[0]) ] = trim( $t[1] );
            else
            {
                $head[] = $v;
                if( preg_match( "#HTTP/[0-9\.]+\s+([0-9]+)#",$v, $out ) )
                    $head['reponse_code'] = intval($out[1]);
            }
        }
        return $head;
    }

Thus, the form works well with recaptcha. 🙂
