  1. For custom form, it is easy to add a recpatcha. But how about on default admin login form ?
  2. Simple Contact Form Using Google Recaptcha & Valitron validation library I just finished creating a simple Contact-Form for a client's website so i thought it would be really helpfull to share it with the community. The contact form uses: Google recaptcha for validating the user is not a robot (https://github.com/google/recaptcha) Valitron validation library for validating the form fields (https://github.com/vlucas/valitron) Twitter Bootstrap 3.0.0 for form HTML The contact-form is located inside a contact-page, so the bare minimum you need in order to setup your own is: contact.php (template file used by your contact-page) _contact-controller.php (file used as a controller for your contact-form functionality like send email, validate fields etc) 2 extra lines inside your composer.json file So, let's start: First you need to update your composer.json file adding 2 lines inside the require object: "vlucas/valitron": "^1.2", "google/recaptcha": "~1.1" Here is a sample composer.json file: { "name": "processwire/processwire", "type": "library", "description": "ProcessWire CMS/CMF", "keywords": [ "cms","cmf", "content management system" ], "homepage": "https://processwire.com", "authors": [ { "name": "Ryan Cramer", "email": "ryan@processwire.com", "homepage": "https://processwire.com", "role": "Developer" } ], "require": { "php": ">=5.3.8", "ext-gd": "*", "vlucas/valitron": "^1.2", "google/recaptcha": "~1.1" }, "autoload": { "files": [ "wire/core/ProcessWire.php" ] }, "minimum-stability": "dev" } open console and navigate to processwire root folder (where composer.json file is) on this step i assume you have already setup composer for your project, otherwise google it run the following command: composer update this will create a vendor folder (if it does not already exist) and download valitron and google recaptcha libraries. Then open your contact-page template file(usually named contact.php inside your templates directory) and add the following: * Note: The form below uses bootstrap 3.0.0 css, so if you are using something else you need to make the appropriate changes. <?php namespace ProcessWire; include('_contact-controller.php') ?> <div class="container"> <div class="row"> <div class=" col-md-4"> <h2>Contact Form</h2> <?php if($session->flashMessage):?> <div class="alert <?=!$session->sent && (!$v->validate() || !$resp->isSuccess()) ? 'alert-danger' : 'alert-success'?>" role="alert"> <?php echo $session->flashMessage;?> </div> <?php endif;?> <form id="contact-form" method="post"> <div class="form-group <?=$v->errors('name') ? 'has-error' : ''?>"> <label for="name">Name</label> <input class="form-control" name="name" id="name" type="text" value="<?=$sanitizer->text($input->post->name)?>"> </div> <div class="form-group <?=$v->errors('email') ? 'has-error' : ''?>"> <label for="email">Email</label> <input class="form-control" name="email" id="email" type="text" value="<?=$sanitizer->text($input->post->email)?>"> </div> <div class="form-group <?=$v->errors('message') ? 'has-error' : ''?>"> <label for="message">Message</label> <textarea class="form-control" name="message" id="message"><?=$sanitizer->text($input->post->message)?></textarea> </div> <div class="form-group"> <!-- Google Recaptcha code START --> <div class="g-recaptcha" data-sitekey="<?=$googleSiteKey?>"></div> <script type="text/javascript" src="https://www.google.com/recaptcha/api.js"> </script> <!-- Google Recaptcha code END --> </div> <button type="submit" class="btn btn-primary">SEND</button> </form> </div> </div> </div> <?php //here we remove the flash-message because it is already shown above the form. $session->remove('flashMessage'); //reset 'sent' variable for future submit $session->sent = false; ?> Next create a file inside you templates directory with name: _contact-controller.php: and set the required variables($googleSiteKey, $contactFormRecipient, $contactPageID) <?php namespace ProcessWire; /** * here we include Valitron & Google recaptcha libraries * make sure the path is correct in your template */ include(dirname(__FILE__) . "/../../vendor/vlucas/valitron/src/Valitron/Validator.php"); include(dirname(__FILE__) . '/../../vendor/google/recaptcha/src/ReCaptcha/ReCaptcha.php'); /** * here we add the form field values to Valitron */ $v = new \Valitron\Validator(array( 'name' => $sanitizer->text($input->post->name), 'email' => $sanitizer->email($input->post->email), 'message' => $sanitizer->text($input->post->message), ) ); /** * validation rules set for each form field * For more details on Valitron/Validator usage visit: * https://github.com/vlucas/valitron */ $v->rule('required', ['name', 'email', 'message']); $v->rule('lengthMin', 'name', 5); $v->rule('email', 'email'); /** * set Google recaptcha site-key & secret-key * create a new key from: https://www.google.com/recaptcha/admin */ $googleSiteKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'; $googleSecretKey = 'YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY'; /** * set the email of the contact form recipient(usually the website owner) */ $contactFormRecipient = 'your@company.com'; /** * set the id of contact-page in order to redirect there when the form is sent */ $contactPageID = '1045'; //here we check whether the 'name' field exists inside post variables (which means the form is posted) if ($input->post->name) { //if fields validation passes if ($v->validate()) { $reCaptcha = new \ReCaptcha\ReCaptcha($googleSecretKey); $resp = $reCaptcha->verify($input->post->{'g-recaptcha-response'}, $_SERVER["REMOTE_ADDR"]); //if google-recaptcha validation passes if ($resp->isSuccess()) { //This is the HTML message $message = ' <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Contact Form | ' . $input->post->name . '</title> </head> <body> <p>' . $input->post->message . '</p> </body> </html>'; //here we send the form to $contactFormRecipient wireMail($contactFormRecipient, $input->post->email, "Contact Form | " . $input->post->name, $message); //here we set a flash-message to notify the user that the form was successfully sent $session->flashMessage = 'Thank you for your message! We will get in touch with you shortly.'; //save in session that the form is sent $session->sent = true; //finally redirect user to contact-page $session->redirect($pages->get($contactPageID)->url); } else { //self explain $session->flashMessage = 'Error while validating you are not a robot!'; } } } ?> Thats all! You now have a simple contact-form working with captcha and field validation! I would be more than happy to help anyone having problems on the setup.
