  1. This module allows you to integrate hCaptcha bot / spam protection into ProcessWire forms. hCaptcha is a great alternative to Google ReCaptcha, especially if you are in the EU and need to comply with privacy regulations. The development of this module is sponsored by schwarzdesign. The module is built as an Inputfield, allowing you to integrate it into any ProcessWire form you want. It's primarily intended for frontend forms and can be added to Form Builder forms for automatic spam protection. There's a step-by-step guide for adding the hCaptcha widget to Form Builder forms in the README, as well as instructions for API usage. Features Inputfield that displays an hCaptcha widget in ProcessWire forms. The inputfield verifies the hCaptcha response upon submission, and adds a field error if it is invalid. All hCaptcha configuration options for the widget (theme, display size etc) can be changed through the inputfield configuration, as well as programmatically. hCaptcha script options can be changed through a hook. Error messages can be translated through ProcessWire's site translations. hCaptcha secret keys and site-keys can be set for each individual inputfield or globally in your config.php. Error codes and failures are logged to help you find configuration errors. Please check the README for setup instructions.

  2. MarkupGoogleRecaptcha Google reCAPTCHA for ProcessWire. This module simply adds reCAPTCHA V2 or Invisible reCAPTCHA to your form. How To Install Download the zip file at Github or from the modules repository Drop the module files in /site/modules/MarkupGoogleRecaptcha In your admin, click Modules > Refresh Click "install" for "MarkupGoogleRecaptcha" Official install/uninstall doc: http://modules.processwire.com/install-uninstall/ API You must create an API key prior to use this module. Goto https://www.google.com/recaptcha/admin to create your own. Next, add the API keys information to the module's settings. Usage Call the module : $captcha = $modules->get("MarkupGoogleRecaptcha"); Call $captcha->getScript(); somewhere to get the javascript used by reCAPTCHA Render reCAPTCHA in a standard HTML <form></form> by calling $captcha->render() or Render reCAPTCHA in an InputfieldForm by passing as argument your form to the render function: $captcha->render($form) Call verifyResponse() to get the result. It return TRUE if the challenge was successful. Example Using ProcessWire's form API : $out = ''; $captcha = $modules->get("MarkupGoogleRecaptcha"); // if submitted, check response if ($captcha->verifyResponse() === true) { $out .= "Hi " . $input->post["name"].", thanks for submitting the form!"; } else { $form = $modules->get("InputfieldForm"); $form->action = $page->url; $form->method = "post"; $form->attr("id+name", "form"); $field = $this->modules->get('InputfieldText'); $field->name = "name"; $field->placeholder = "name"; $form->add($field); // CAPTCHA - our form as argument, the function will add an InputfieldMarkup to our form $captcha->render($form); // add a submit button $submit = $this->modules->get("InputfieldSubmit"); $submit->name = "submit"; $submit->value = 'Submit'; $form->add($submit); $out .= $form->render(); // include javascript $out .= $captcha->getScript(); } echo $out; Example using plain HTML Form : $captcha = $modules->get("MarkupGoogleRecaptcha"); // if submitted check response if ($captcha->verifyResponse() === true) { $out .= "Hi " . $input->post["name"] . ", thanks for submitting the form!"; } else { $out .= "<form method='post' action='{$page->url}'>\n" . "\t<input type='text' name='name'>\n" . $captcha->render() // render reCaptcha . "\t<input type='submit'>\n" . "</form>\n"; $out .= $captcha->getScript(); } echo $out;
  3. I was wondering if anyone has successfully integrated Securimage with Processwire 3. I've tried the suggested fixes posted here, but I haven't managed to get the captcha image to display. This might be because the instructions relate to Processwire version 2.x where I am working with version 3. Any ideas/steps what to do would be appreciated.
  4. Hi everybody, As much as we hate the CAPTCHA, it is still used. I decided to share my solution of using ProcessWire forms with CAPTCHA. My goals were quite simple: 1. Create a form and customize it. 2. Get an Inputfield for a page field and append this Inputfield to the form. 3. Display a CAPTCHA. 4. Process the form and check its fields for correctness. 5. Check the CAPTCHA. 6. If steps 4-5 fail, display the form back with the user input intact. What I found to be not quite easy was how to push a different CAPTCHA into an already submitted form. (A spoiler: this is done quite smoothly with the power of ProcessWire's Inputfields.) Let's start, then. My Form class has several methods: appendFields() accepts an array of field names, gets their Inputfields from a template and appends these to the form displayForm() adds a CAPTCHA and returns the form's HTML processForm() checks the CSRF session ID and user input and delegates CAPTCHA verification getCAPTCHA() returns the html for the CAPTCHA checkCAPTCHA() checks the user input against the CAPTCHA and sets the verification flag to true or false. That's mostly it. Now to the code itself. class Form { public $form; public $captchaVerificationResult; // captcha verification flag (bool) public function __construct () { // form is created upon class instantiation $form = wire('modules')->get("InputfieldForm"); $form->action = wire('page')->path; $form->method = 'post'; $form->attr("id+name", 'form'); $form->attr("class", 'pure form'); // I use PureCSS class name here as an example // how form items are displayed can be customized $form->setMarkup(array ( 'list' => "\n{out}\n", 'item' => "\n\t{out}\n\t", 'item_label' => "\n\t\t<label class='pure-form' for='{for}'>{out}</label>", 'item_content' => "\n\t{out}\n\t", 'item_error' => "\n<p><span class='ui-state-error'>{out}</span></p>", 'item_description' => "\n<p class='description'>{out}</p>", 'item_head' => "\n<h2>{out}</h2>", 'item_notes' => "\n<p class='notes'>{out}</p>", ) ); // form classes can also be customized $form->setClasses(array ( 'list' => 'Inputfields', 'list_clearfix' => 'ui-helper-clearfix', 'item' => '', 'item_required' => '', 'item_error' => 'ui-state-error InputfieldStateError', 'item_collapsed' => '', 'item_column_width' => '', 'item_column_width_first' => '', ) ); $this->form = $form; } public function appendFields ($fields) { /* * $fields is an array of field names * * for each field name a corresponding Inputfield is fetched from a page * and appended to the form * */ $page = wire('pages')->get("999999999"); // this is the page that has your fields foreach ($fields as $f_name) { $field = wire('fields')->get($f_name); $if = $field->getInputfield($page); // this page must have field name $f_name among its fields! $this->form->append($if); } /* * * CAPTCHA placeholder */ /* * create an InputfieldMarkup field, * give it an ID and append to the form * * Later this Inputfield can be easily found by its ID. * * */ $inputfield = new InputfieldMarkup; // inputfield markup is appendable to form! $inputfield->id = 'captcha1'; // id of the InputfieldMarkup with CAPTCHA $this->form->append($inputfield); /** * finally, the SUBMIT button * */ $submit = wire('modules')->get('InputfieldSubmit'); $submit->skipLabel = Inputfield::skipLabelBlank; // remove the label $submit->name = 'submit_save'; $submit->value = "Save"; $this->form->append($submit); } public function get () { return $this->form; } public function displayForm ($form) { /* * Each time the form is displayed, the CAPTCHA should be there * * So, behore doing $form->render() let's get an InputFieldMarkup field by ID * and pour some fresh CAPTCHA in it * * */ $form->children->findOne("id=captcha1")->value .= $this->getCAPTCHA(); return $form->render(); } public function processForm ($form) { try { $form->processInput(wire('input')->post); wire('session')->CSRF->validate(); } catch (WireCSRFException $e) { die ($this->displayForm($form)); } $this->checkCAPTCHA(); // sets class property $captcha_verification_result to false/true if (!$this->captcha_verification_result) { $form->children->findOne("id=captcha1")->value = "Wrong captcha, try again <br />"; // this will go before the CAPTCHA code die($this->displayForm($form)); } else { // let's do some simple checks // you can and should do more of yours, of course $email = $form->get("b_email"); if (filter_var($email->value, FILTER_VALIDATE_EMAIL)) { $email->error = "Incorrect email format"; } if ($form->getErrors()) { // the form contains errors, display it with user input die($this->displayForm($form)); } else { echo "Thanks for the submission!"; // everything is just right } } } public function getCAPTCHA () { /* * * $captcha_html = your CAPTCHA code * */ return $captcha_html; // have a lovely CAPTCHA } public function checkCAPTCHA () { /* * * get some response and check it * * */ if ($response->failed) { $this->captchaVerificationResult = false; } else { $this->captchaVerificationResult = true; } } } Here's how this can be used: $form = new Form(); $formFields = array ("name", "email"); $form->appendFields($formFields); $newForm = $form->get(); if ($input->post->submit_save) { // user submitted the form, process it and check for errors $form->processForm($newForm); // the form was processed successfully because nothing die()'d. Now it's time to play with what's been submitted. } else { echo $form->displayForm($newForm); // if it's not been submitted, just display it and the CAPTCHA } With this being just a generic idea on how to do form processing with CAPTCHA, I hope portions of this code will prove helpful in your development. Your comments, corrections and suggestions are very much welcome.
  5. I'm use inputfieldForm module for custom form at front-end on my project and except CFRS there is necessary an input Captcha, it would be healthy if it is available in modules by default!
