  1. I am trying to implement the new version of captcha on my website. What i did so far: Inside the FORM: echo '<div class="g-recaptcha" data-sitekey="XXXXXXXXXXXXXXXXXXXXXXXXXXXX"></div>'; Inside PHP: $recaptcha = $_POST['g-recaptcha-response']; if(!empty($recaptcha)) { $google_url = "https://www.google.com/recaptcha/api/siteverify"; $secret = 'YYYYYYYYYYYYYYYYYYYYYYYYYYY'; $ip = $_SERVER['REMOTE_ADDR']; $url = $google_url."?secret=".$secret."&response=".$recaptcha."&remoteip=".$ip; $res = getCurlData($url); $res = json_decode($res, true); if($res['success'] == 'false') { $captcha_error = "Please re-enter your reCAPTCHA."; } } The getCurlData function: function getCurlData($url) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_TIMEOUT, 10); curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16"); $curlData = curl_exec($curl); curl_close($curl); return $curlData; } What i want to achieve is to know when the no-Captcha box is checked. I want to throw an error to the user if he/she did not check that box. So far i only throw an error if the response from Google is "We are not sure if you are human, please proceed to our second level of verification" [if($res['success'] == 'false')]. PS: most of the code is written by Srinivas Tamada. You can find it here. Thanks in advance.
  2. Just a bit of background first: I have a contact form set up on one of my domains. It hasn't been updated in 7 years and recently I started getting about 3-8 spam messages daily through it. At some point I updated other sites with code that includes a CAPTCHA. Out of sheer laziness, instead of recoding the contact form that was getting spammed, I just copied & pasted one of the updated forms and changed the necessary details like which e-mail address, URL, etc. Unfortunately, this hasn’t worked out properly. For some reason the CAPTCHA image isn’t being displayed. I keep looking but can't find the error(s). Could someone please take a look at the code and tell me what went wrong? I’d be ever so grateful for any help! The code for the form itself: <form method="post" action="mail-e.php"> <p><input type="text" name="name" id="name" value="who are you?" size="25" /></p> <p><input type="text" name="email" id="email" value="you@whatever.bla" size="25" /></p> <p><input type="text" name="url" id="url" value="http://" size="25" /></p> <p><textarea name="comments" id="comments" rows="1" cols="20">Go on, then. Tell me a story, wingy!</textarea></p> <p><img src="http://echoing.org/captcha.php" alt="humanity check" /><br /> <input type="text" name="captcha" id="captcha" /> <br /> <p><input type="submit" name="submit" id="submit" value="sing to me" /> <input type="reset" name="reset" id="reset" value="out of key" /></p> </form> mail-e.php: <?php session_start(); //Encrypt the posted code field and then compare with the stored key if(md5($_POST['captcha']) != $_SESSION['key']) { die("Error: You must enter the code correctly"); }else{ echo 'You entered the code correctly'; } ?> <?php if (!isset($_POST['submit'])) { include('./header.php'); echo "<h1>HEY!!! You just encountered an error!</h1>\n <p>You don't belong here. <strong>Because it's <em>wrong</em>.</strong> Go back and try again, please.</p>"; include('./footer.php'); exit; } function cleanUp($data) { $data = strip_tags($data); $data = trim(htmlentities($data)); return $data; } $name = cleanUp($_POST['name']); $email = cleanUp($_POST['email']); $url = cleanUp($_POST['url']); $comments = cleanUp($_POST['comments']); if ((empty($name)) || (empty($email)) || (empty($comments))) { include('./header.php'); echo "<h2>Input Error!

Your message was successfully sent to me! I'll read it as soon as I can. I may even respond! Thanks for using the form, fruitcake </p>"; include('./footer.php'); } else { include('./header.php'); echo "<p>Something went awry. Your message didn't go through. Want to take another crack at it? Please do, I'd love to hear from you!</p>"; include('./footer.php'); } ?> captcha.php: <?php //Start the session so we can store what the code actually is. session_start(); //Now lets use md5 to generate a totally random string $md5 = md5(microtime() * mktime()); /* We dont need a 32 character long string so we trim it down to 5 */ $string = substr($md5,0,5); /* Now for the GD stuff, for ease of use lets create the image from a background image. */ $captcha = imagecreatefromjpeg("http://echoing.org/captcha.jpg"); /* Lets set the colours, the colour $line is used to generate lines.

Lets add some lines in (static lines) to attempt to make the bots life a little harder */ imageline($captcha,0,0,39,29,$line); imageline($captcha,40,0,64,29,$line); /* Now for the all important writing of the randomly generated string to the image. */ imagestring($captcha, 5, 20, 10, $string, $black); /* Encrypt and store the key inside of a session */ $_SESSION['key'] = md5($string); /* Output the image */ header("Content-type: image/jpeg"); imagejpeg($captcha); ?> I don’t know where it all went wrong as I’m using pretty much the same code without problems here, here and here. The form isn't being used presently (apart from the spam) but I am itching to know what the problem is. P.S. The link to the CAPTCHA image wasn’t always http://echoing.org/captcha.php in the code. On the other forms and initially with this one the code was ./captcha.php but I changed it in case that was the problem. Looks like it isn’t. Thanks in advance!
  3. HI recently we have been starting to recieved about 30 spam emails aday. I read that the issue was how my forms were submitting and that it kept bypassing the javascript. I found some code i could use at http://chrisplaneta.com/freebies/php_contact_form_script_with_recaptcha/ but i cannot seem to get the form to function correctly. It is supposed to email me once the form is validated but the email does not seem to be sending. Also i would like the form to redirect to a thank you page once it has been agreed. I did try but it kept telling me the headers had already been called. i am calling the page in with php include. Can you please advise the best way for me to relocate. I have attached a copy of my form.php page which has every thing on. I have also included the code at the bottom of this email Also i would appreciate any comments on what i can include on my form to limit the spammers <?php //If the form is submitted: if(isset($_POST['submitted'])) { //load recaptcha file require_once('captcha/recaptchalib.php'); //enter your recaptcha private key $privatekey = "6Ld5Df4SAAAAAKciqwDco8dfvBR15fGeFVXWcvCO"; //check recaptcha fields $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); //Check to see if the invisible field has been filled in if(trim($_POST['checking']) !== '') { $blindError = true; } else { //Check to make sure that a contact name has been entered $authorName = (filter_var($_POST['formAuthor'], FILTER_SANITIZE_STRING)); if ($authorName == ""){ $authorError = true; $hasError = true; }else{ $formAuthor = $authorName; }; //Check to make sure sure that a valid email address is submitted $authorEmail = (filter_var($_POST['formEmail'], FILTER_SANITIZE_EMAIL)); if (!(filter_var($authorEmail, FILTER_VALIDATE_EMAIL))){ $emailError = true; $hasError = true; } else{ $formEmail = $authorEmail; }; //Check to make sure the subject of the message has been entered $msgSubject = (filter_var($_POST['formSubject'], FILTER_SANITIZE_STRING)); if ($msgSubject == ""){ $subjectError = true; $hasError = true; }else{ $formSubject = $msgSubject; }; //Check to make sure content has been entered $msgContent = (filter_var($_POST['formContent'], FILTER_SANITIZE_STRING)); if ($msgContent == ""){ $commentError = true; $hasError = true; }else{ $formContent = $msgContent; }; // if all the fields have been entered correctly and there are no recaptcha errors build an email message if (($resp->is_valid) && (!isset($hasError))) { $emailTo = 'carlycyber@hotmail.co.uk'; // here you must enter the email address you want the email sent to $subject = 'A new message from: immigration solicitors Manchester' ; $body = "Name :formAuthor \n\nEmail: $formEmail \n\nTelephone :formSubject \n\nContent: $formContent \n\n$formAuthor"; // This is the body of the email $headers = 'From: <'.$formEmail.'>' .

  4. Hello everyone, I run a small url shorting service. I have bought the script and everything which short long urls. And i want to use a php code in one of the pages. Let me explain you in detail first. My site is https://786.pw and user goes there and enter the long url and the short url becomes something like https://786.pw/shorturl ( for example) Now when this short url which is https://786.pw/shorturl is hit the user is redirected to the original long url. And thats how it is supposed to work. But in between i have the option to show a splash page which can be a advertisement or a timer or anything " The code of splash.php is :- <?php defined("APP") or die() // Media Page ?> <?php include_once("analyticstracking.php") ?> <section> <div class="container splash"> <?php echo $this->ads(728,FALSE) ?> <div class="row"> <div class="col-md-4 thumb"> <div class="panel panel-dark panel-body"> <img src="<?php echo $url->short ?>/i"> </div> </div> <div class="col-md-8"> <div class="panel panel-default panel-body"> <h2> <?php if (!empty($url->meta_title)): ?> <?php echo $url->meta_title ?> <?php else: ?> <?php echo e("You are about to be redirected to another page.") ?> <?php endif ?> </h2> <p class="description"> <?php if (!empty($url->meta_description)): ?> <?php echo $url->meta_description ?> <?php endif ?> </p> <br> <div class="row"> <div class="col-sm-6"> <a href="<?php echo $this->config["url"] ?>/?r=<?php echo base64_encode($url->url) ?>" class="btn btn-primary btn-block redirect" rel="nofollow"><?php echo e("Redirect me"); ?></a> </div> <div class="col-sm-6"> <a href="<?php echo $this->config["url"] ?>" class="btn btn-default btn-block" rel="nofollow"><?php echo e("Take me to your homepage") ?></a></a> </div> </div> <hr> <p class="disclaimer"> <?php echo e("You are about to be redirected to another page. We are not responsible for the content of that page or the consequences it may have on you.") ?> </p> </div> </div> </div> </div> </section> Now, I want to add solve media php script in it. Which means any user who is using our url shortner service needs to complete the captcha before he can be finally directed to the destination url. The script supports solvemedia captcha solving. I spoke to the creator of this script and he told me this. "You will need to have some basic php knowledge to achieve this. To add the catpcha you need to use <?php echo Main::captcha() ?> which will echo the captcha To validate the result you need to use <?php if(Main::check_captcha($_POST) == "ok") { // If captcha is ok do something here }else{ // else do something here } ?> " I dont have any php knoweldge., How can i enter this code in splash.php in order to show the captcha ? Please suggest. And ask any question if you need
