Markup Google reCAPTCHA

Recommended Posts

MarkupGoogleRecaptcha

Google reCAPTCHA for ProcessWire.

This module simply adds reCAPTCHA V2 or Invisible reCAPTCHA to your form.


How To Install

  1. Download the zip file at Github or from the modules repository
  2. Drop the module files in /site/modules/MarkupGoogleRecaptcha
  3. In your admin, click Modules > Refresh
  4. 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

  1. Call the module : $captcha = $modules->get("MarkupGoogleRecaptcha");
  2. Call $captcha->getScript(); somewhere to get the javascript used by reCAPTCHA
  3. 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)
  4. 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;

Looks like you're running PHP 5.3 on the live system. You could fix this error by replacing the short array notation [...] used throughout the module with its verbose notation as array(...), but you should really think of switching to a more current PHP release.

I have a pull-request for this module, pull-request adding multi language support to reCAPTCHA and multiple usage on one page. You can see usage on screenshot.

For set reCAPTCHA language, (reCAPTCHA Language Codes) :

<?php if(modules()->isInstalled('MarkupGoogleRecaptcha')) { echo modules()->MarkupGoogleRecaptcha->render($lang = "en"); }; ?>

For multiple reCAPTCHA usage, after all form render, call multiple usage script :

<?php if(modules()->isInstalled('MarkupGoogleRecaptcha')) { echo modules()->MarkupGoogleRecaptcha->getScriptMulti(); }; ?>

Good day!

Thank you @flydev for the very useful module and @ukyo for making it possible to have multiple instances of reCAPCHA on the same page.

I am having just that: two forms on the same page both with reCAPCHA via the module. Both work using jQuery ajax. After an unsuccessful call I get response with error messages. Right here I need to reset reCAPCHA like described here in the JavaScript API section. But as I have two instances of reCAPCHA on the page I need to explicitly specify the opt_widget_id option. Is there a way to I get it with the module?

You have an option, don't call getScriptMulti(); function.

<?php if(modules()->isInstalled('MarkupGoogleRecaptcha')) { echo modules()->MarkupGoogleRecaptcha->getScriptMulti(); }; ?>

Write your own javascript by referencing getScriptMulti(); function.

    public function getScriptMulti() {
        $return = "<script type=\"text/javascript\">
                    var onloadReCaptchaCallback = function(){
                        jQuery('.g-recaptcha').each(function() {
                            var _this = jQuery(this);
                            var recaptchaID = _this.data('id'),
                                hl = _this.data('hl'),
                                sitekey = _this.data('sitekey'),
                                theme = _this.data('theme'),
                                type = _this.data('type'),
                                size = _this.data('size'),
                                index = _this.data('index');
                            if(recaptchaID !== undefined) {
                                var recaptchaWidget = grecaptcha.render(recaptchaID, {
                                    'hl' : hl,
                                    'sitekey' : sitekey,
                                    'theme' : theme,
                                    'type' : type,

                                grecaptcha.getResponse(recaptchaWidget);
                                // grecaptcha.reset(recaptchaWidget);

        return $return;

Just bumped the module to version 2.

- Added  Google Invisible reCAPTCHA.

 

To use it, no change is necessary on the frontend, you just have to configure the module to use reCAPTCHA V2 or Invisible reCAPTCHA.

I will update the readme to reflect the change made by @ukyo and the new available options.

I am wondering to add the reCAPTCHA to the login form of the Login-Register module.

I tried to make it by using the MarkupGoogleRecaptcha API in a hook, but without success:

// ready.php file
wire()->addHookAfter('LoginRegister::buildLoginForm', function($event) {

  $form = $event->return;

  // call the module and render reCAPTCHA
  $captcha = wire('modules')->get("MarkupGoogleRecaptcha");
  $captcha->render($form);

  // add JavaScript to the form
  $js = $captcha->getScript();
  // ... str_replace("</form>", "{$js}</form>", $form);

  // Call verifyResponse() to get the result.
  // ...

  $event->return = $form;

});

Furthermore, I do know if it is possible to add reCAPTCHA from within a hook.

Can someone help me in adding the reCAPTCHA to the login form of the Login-Register module?

Hi @LAPS

try the following :  In ready.php put the following code :

$captchaobj = null;

    wire()->addHookProperty('LoginRegister::captcha', function ($event) {
        $event->return = wire('modules')->get("MarkupGoogleRecaptcha");
    });

    wire()->addHookAfter('LoginRegister::buildLoginForm', function ($event) {
        /* @var $form InputfieldForm */
        $obj = $event->object;
        $form = $event->return;
        $form->description = false; // remove the description
        $f = new InputfieldMarkup();
        $f->markupText = $obj->captcha->render();
        foreach ($form->children as $field) {
            if ($field instanceof InputfieldSubmit) { // find the submit button
                $form->insertBefore($f, $field);      // insert reCAPTCHA before the submit button
            }
        }

        $event->return = $form;
    });

    wire()->addHookBefore('LoginRegister::processLoginForm', function ($event) use (&$captchaobj) {
        $obj = $event->object;
        $captchaobj = $obj->captcha;
    });

    wire()->addHookBefore('Session::login', function ($event) use (&$captchaobj) {
        if (!is_null($captchaobj) && $captchaobj->verifyResponse() == false) {
            $event->arguments(0, '');
            $event->arguments(1, '');
            $event->arguments(2, false);
            $event->return = false;
        }
    });

 

Just one thing, I couldn't get the invisible mode to work with LoginRegister, only the reCAPTCHA v2.

edit:  a small hint about the getScript() :  you should call it from the main file, I mean, your "index.php" and only if the user isn't loggedin.

if(!$user->isLoggedin()) {
	echo $modules->get("MarkupGoogleRecaptcha")->getScript();
}

Hi @flydev,

thank you for you reply.

However, your code seems do not work. In particular, it seems do not output the JavaScript-related code ($captcha->getScript()). Can be this the problem?

Note: I am testing MarkupGoogleRecaptcha in localhost, so in Google Admin I added the domains 'localhost' and '127.0.0.1'.

Yes it is. Read my last edit in my previous post.

 

Localhost for testing is fine, no problem with that.

@flydev,

Thank you for your hint. Now the reCAPTCHA is visible in the login form (see the attached image).

However, even when submitting the correct user credentials, I get always the "Login failed" message. What's wrong?

Good, now I think that your google challenge is not successful. Be sure that you saved the changes in your list of supported domains once you added the localhost.

 

Anything in the developer console ?

In Google Admin I set 'localhost' and '127.0.0.1' (see attached image).

I tried to submit the login form from both 'http://localhost:8888/login' and 'http://127.0.0.1:8888/login' without success: I get the "Login failed" message.

 

Note: If it can help, in Google Admin I cannot set 'localhost:8888' nor '127.0.0.1:8888' since I get the error "URL starts with an invalid scheme".

Did the challenge work ? I mean, the reCapatcha widget is "green-checked" ?

To be sure that the problem is not in the code I give you (I am currently using the same snippet on a website) ,  you should try to get the challenge working on a regular module call in a regular form. Can you test it  and report back ?

I tested it in a regular form, and it works as expected. It does not work just for the Login-Register login form.

OK, we are close to the solution.

If it can help, I am using:

  • ProcessWire v3.0.62
  • Login/Register v0.0.2 with option "Features to use" set to all (including "Use email address for login rather that user name") and option "Profile form fields" set to "E-mail Address (required)" and "Set Password (required)" more "First name" and "Last name".

Furthermore, after the login form submission (failed) in the Session logs I get these 2 rows:

2 seconds ago --- Error: Failed login for '' - Unknown user:
2 seconds ago --- Error: Failed login for 'my_email-email.com' - Unknown user: my_email-email.com

Hi @flydev. Great module. I'm using it on a custom form. I'd like to add it to an existing site where I've used Ryan's Form Template Processor module. (It's a long form; I'd rather not start from scratch). I've had a look at what you did with the log in form above; would I take a similar approach? Is there an easy way to slot the Captcha form in before the submit button (instead of outside the generated form)? I'm pretty new to hooks, if that's what's needed. Any suggestions appreciated.

hi @strandoo thanks you.

 

I never used the module you are talking about but I read the module code on Github and it look like you can insert the ReCaptcha before the submit button by hooking into the function ___buildForm().

Please try the following (not tested) and let me know. In ready.php put :

wire()->addHookAfter('FormTemplateProcessor::buildForm', function ($event) {
        /* @var $form InputfieldForm */
        $form = $event->return;
        $f = new InputfieldMarkup();
        $f->markupText = wire('modules')->get("MarkupGoogleRecaptcha")->render();
        foreach ($form->children as $field) {
            if ($field instanceof InputfieldSubmit) { // find the submit button
                $form->insertBefore($f, $field);      // insert reCAPTCHA before the submit button
            }
        }

        $event->return = $form;
    });

Hi @flydev My, that was quick! I did put this in my ready.php file, but don't see a captcha. Do I need to include your '$captcha = $modules->get("MarkupGoogleRecaptcha");' on the page? (I've tried it both ways). I've also tried this $f->markupText = 'Foobar'; (instead of your module) and 'Foobar' appears above the submit button, as expected.

      Page Query Boss
      Build complex nested queries containing multiple fields and pages and return an array or JSON. This is useful to fetch data for SPA and PWA.
      You can use the Module to transform a ProcessWire Page or PageArray – even RepeaterMatrixPageArrays – into an array or JSON. Queries can be nested and contain closures as callback functions. Some field-types are transformed automatically, like Pageimages or MapMarker.
      Installation
      Via ProcessWire Backend
      It is recommended to install the Module via the ProcessWire admin "Modules" > "Site" > "Add New" > "Add Module from Directory" using the PageQueryBoss class name.
      Manually
      Download the files from Github or the ProcessWire repository: https://modules.processwire.com/modules/page-query-builder/
      Copy all of the files for this module into /site/modules/PageQueryBoss/ Go to “Modules > Refresh” in your admin, and then click “install” for the this module. Module Methods
      There are two main methods:
      Return query as JSON
      $page->pageQueryJson($query); Return query as Array
      $page->pageQueryArray($query); Building the query
      The query can contain key and value pairs, or only keys. It can be nested and 
      contain closures for dynamic values. To illustrate a short example:
      // simple query: $query = [ 'height', 'floors', ]; $pages->find('template=skyscraper')->pageQueryJson($query); Queries can be nested, contain page names, template names or contain functions and ProcessWire selectors:
      // simple query: $query = [ 'height', 'floors', 'images', // < some fileds contain default sub-queries to return data 'files' => [ // but you can also overrdide these defaults: 'filename' 'ext', 'url', ], // Assuming there are child pages with the architec template, or a // field name with a page relation to architects 'architect' => [ // sub-query 'name', 'email' ], // queries can contain closure functions that return dynamic content 'querytime' => function($parent){ return "Query for $parent->title was built ".time(); } ]; $pages->find('template=skyscraper')->pageQueryJson($query); Keys:
      A single fieldname; height or floors or architects 
      The Module can handle the following fields:
      Strings, Dates, Integer… any default one-dimensional value Page references Pageimages Pagefiles PageArray MapMarker FieldtypeFunctional A template name; skyscraper or city
      Name of a child page (page.child.name=pagename); my-page-name A ProcessWire selector; template=building, floors>=25
      A new name for the returned index passed by a # delimiter:
      // the field skyscraper will be renamed to "building": $query = ["skyscraper`#building`"]  
      Key value pars:
      Any of the keys above (1-5) with an new nested sub-query array:
      $query = [ 'skyscraper' => [ 'height', 'floors' ], 'architect' => [ 'title', 'email' ], ]  
      A named key and a closure function to process and return a query. The closure gets the parent object as argument:
      $query = [ 'architecs' => function($parent) { $architects = $parent->find('template=architect'); return $architects->arrayQuery(['name', 'email']); // or return $architects->explode('name, email'); } ] Real life example:
      $query = [ 'title', 'subtitle', // naming the key invitation 'template=Invitation, limit=1#invitation' => [ 'title', 'subtitle', 'body', ], // returns global speakers and local ones... 'speakers' => function($page){ $speakers = $page->speaker_relation; $speakers = $speakers->prepend(wire('pages')->find('template=Speaker, global=1, sort=-id')); // build a query of the speakers with return $speakers->arrayQuery([ 'title#name', // rename title field to name 'subtitle#ministry', // rename subtitle field to ministry 'links' => [ 'linklabel#label', // rename linklabel field to minlabelistry 'link' ], ]); }, 'Program' => [ // Child Pages with template=Program 'title', 'summary', 'start' => function($parent){ // calculate the startdate from timetables return $parent->children->first->date; }, 'end' => function($parent){ // calculate the endate from timetables return $parent->children->last->date; }, 'Timetable' => [ 'date', // date 'timetable#entry'=> [ 'time#start', // time 'time_until#end', // time 'subtitle#description', // entry title ], ], ], // ProcessWire selector, selecting children > name result "location" 'template=Location, limit=1#location' => [ 'title#city', // summary title field to city 'body', 'country', 'venue', 'summary#address', // rename summary field to address 'link#tickets', // rename ticket link 'map', // Mapmarker field, automatically transformed 'images', 'infos#categories' => [ // repeater matrix! > rename to categories 'title#name', // rename title field to name 'entries' => [ // nested repeater matrix! 'title', 'body' ] ], ], ]; if ($input->urlSegment1 === 'json') { header('Content-type: application/json'); echo $page->pageQueryJson($query); exit(); } Module default settings
      The modules settings are public. They can be directly modified, for example:
      $modules->get('PageQueryBoss')->debug = true; $modules->get('PageQueryBoss')->defaults = []; // reset all defaults Default queries for fields:
      Some field-types or templates come with default selectors, like Pageimages etc. These are the default queries:
      // Access and modify default queries: $modules->get('PageQueryBoss')->defaults['queries'] … public $defaults = [ 'queries' => [ 'Pageimages' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus', ], 'Pagefiles' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'filesize', 'filesizeStr', 'hash', ], 'MapMarker' => [ 'lat', 'lng', 'zoom', 'address', ], 'User' => [ 'name', 'email', ], ], ]; These defaults will only be used if there is no nested sub-query for the respective type. If you query a field with complex data and do not provide a sub-query, it will be transformed accordingly:
      $page->pageQueryArry(['images']); // returns something like this 'images' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus'=> [ 'top', 'left', 'zoom', 'default', 'str', ] ]; You can always provide your own sub-query, so the defaults will not be used:
      $page->pageQueryArry([ 'images' => [ 'filename', 'description' ], ]); Overriding default queries:
      You can also override the defaults, for example
      $modules->get('PageQueryBoss')->defaults['queries']['Pageimages'] = [ 'basename', 'url', 'description', ]; Index of nested elements
      The index for nested elements can be adjusted. This is also done with defaults. There are 3 possibilities:
      Nested by name (default) Nested by ID Nested by numerical index Named index (default):
      This is the default setting. If you have a field that contains sub-items, the name will be the key in the results:
      // example $pagesByName = [ 'page-1-name' => [ 'title' => "Page one title", 'name' => 'page-1-name', ], 'page-2-name' => [ 'title' => "Page two title", 'name' => 'page-2-name', ] ] ID based index:
      If an object is listed in $defaults['index-id'] the id will be the key in the results. Currently, no items are listed as defaults for id-based index:
      // Set pages to get ID based index: $modules->get('PageQueryBoss')->defaults['index-id']['Page']; // Example return array: $pagesById = [ 123 => [ 'title' => "Page one title", 'name' => 123, ], 124 => [ 'title' => "Page two title", 'name' => 124, ] ] Number based index
      By default, a couple of fields are transformed automatically to contain numbered indexes:
      // objects or template names that should use numerical indexes for children instead of names $defaults['index-n'] => [ 'Pageimage', 'Pagefile', 'RepeaterMatrixPage', ]; // example $images = [ 0 => [ 'filename' => "image1.jpg", ], 1 => [ 'filename' => "image2.jpg", ] ] Tipp: When you remove the key 'Pageimage' from $defaults['index-n'], the index will again be name-based.
       
      Debug
      The module respects wire('config')->debug. It integrates with TracyDebug. You can override it like so:
      // turns on debug output no mather what: $modules->get('PageQueryBoss')->debug = true; Todos
      Make defaults configurable via Backend. How could that be done in style with the default queries?

      General
      This is a lightweight alternative to other newsletter & newsletter-subscription modules.
      It can subscribe, update, unsubscribe & delete a user in a list in Mailchimp with MailChimp API 3.0. It does not provide any forms or validation, so you can feel free to use your own. To protect your users, it does not save any user data in logs or sends them to an admin.
      This module fits your needs if you...
      ...use Mailchimp as your newsletter / email-automation tool ...want to let users subscribe to your newsletter on your website ...want to use your own form, validation and messages (with or without the wire forms) ...don't want any personal user data saved in any way in your ProcessWire environment (cf. EU data regulation terms) ...like to subscribe, update, unsubscribe or delete users to/from different lists ...like the Mailchimp UI for creating / sending / reviewing email campaigns You can find it here: https://github.com/danielstieber/SubscribeToMailchimp
      Let me know what you think and if I should add it to the Modules Directory.
      Setup
      Log into your Mailchimp account and go to  Profile > Extras > API Keys. If you don't have an API Key, create a new one. Copy your API Key and paste it in the module settings (Processwire > Modules > Site > SubscribeToMailchimp). Back in Mailchimp, go to the list, where you want your new subscribers. Go to Settings > List name and defaults. Copy the List ID an paste it in to the module settings.
      Usage
      To use the module, you need to load it into your template:
      $mc = $modules->get("SubscribeToMailchimp"); Now you can pass an email address to the module and it will try to edit (if the user exists) or create a new subscriber in your list.
      $mc->subscribe('john.doe@example.com'); You can also pass a data array, to add additional info.
      $mc->subscribe('john.doe@example.com', ['FNAME' => 'John', 'LNAME' => 'Doe']); You can even choose an alternative list, if you don't want this subscriber in your default list.
      $mc->subscribe('john.doe@example.com', ['FNAME' => 'John', 'LNAME' => 'Doe'], 'abcdef1356'); // Subscribe to List ID abcdef1356 If you want to unsubscribe a user from a list, you can use the unsubscribe method.
      $mc->unsubscribe('john.doe@example.com'); // Unsubscribe john.doe@example.com from the default list $mc->unsubscribe('john.doe@example.com', 'abcdef1356'); // Unsubscribe john.doe@example.com from the list abcdef1356 If you want to permantly delete a user, you can call the delete method. Carefully, this step cannot be undone
      $mc->delete('john.doe@example.com'); // Permanently deletes john.doe@example.com from the default list $mc->delete('john.doe@example.com', 'abcdef1356'); // Permanently deletes john.doe@example.com from the list abcdef1356  
      Important Notes
      This module does not do any data validation. Use a sever-sided validation like Valitron Make sure that you have set up your fields in your Mailchimp list. You can do it at Settings > List fields and *|MERGE|* tags Example
      Example usage after a form is submitted on your page:
      // ... validation of form data $mc = $modules->get("SubscribeToMailchimp"); $email = $input->post->email; $subscriber = [ 'FNAME' => $input->post->firstname, 'LNAME' => $input->post->lastname, ]; $mc->subscribe($email, $subscriber);  
      Troubleshooting
      In case of trouble check your ProcessWire warning logs.
      I can't see the subscriber in the list
      If you have enabled double opt-in (it is enabled by default) you will not see the subscriber, until he confirmed the subscription in the email sent by Mailchimp
      I get an error in my ProccessWire warning logs
      Check if you have the right List ID and API Key. Check if you pass fields, that exist in your list. Check if you pass a valid email address. Go to Mailchimps Error Glossary for more Information

      As threatened in the Pub sub forum in the "What are you currently building?" thread, I've toyed around with Collabora CODE and built file editing capabilities for office documents (Libre-/OpenOffice formats and MS Office as well as a few really old file types) into a PW module.
      If you are running OwnCloud or NextCloud, you'll perhaps be familiar with the Collabora app for this purpose.
      LoolEditor
      Edit office files directly in ProcessWire
      Edit your docx, odt, pptx, xlsx or whatever office files you have stored in your file fields directly from ProcessWire's page editor. Upload, click the edit icon, make your changes and save. Can be enabled per field, even in template context.
      Currently supports opening and saving of office documents. Locking functionality is in development.
      See the README on GitHub for installation instructions. You should be reasonably experienced with configuring HTTPS and running docker images to get things set up quickly.
      Pull requests are welcome!
      Here is a short demonstration:

      An Images field allows you to:
      Rename images by clicking the filename in the edit panel or in list view. Replace images, keeping metadata and filename (when possible) by dropping a new image on the thumbnail in the edit panel. Introduced here. But neither of these things is possible in File fields, which prompted this module. The way that files are renamed or replaced in this module is not as slick as in the Images field but it gets the job done. The most time-consuming part was dealing with the UI differences of the core admin themes. @tpr, gives me even more respect for the work that must go into AdminOnSteroids.
      Most of the code to support the rename/replace features is already present in InputfieldFile - there is just no UI for it currently. So hopefully that means these features will be offered in the core soon and this module can become obsolete.
       
      Files Rename Replace
      Allows files to be renamed or replaced in Page Edit.

      Usage
      Install the Files Rename Replace module.
      If you want to limit the module to certain roles only, select the roles in the module config. If no roles are selected then any role may rename/replace files.
      In Page Edit, click "Rename/Replace" for a file...
      Rename
      Use the text input to edit the existing name (excluding file extension).
      Replace
      Use the "Replace with" select to choose a replacement file from the same field. On page save the file will be replaced with the file you selected. Metadata (description, tags) will be retained, and the filename also if the file extensions are the same.
      Tip: newly uploaded files will appear in the "Replace with" select after the page has been saved.

      So I decided to wade into module development and created a wrapper module around ImageOptim, a service that compresses and optimizes images in the cloud. ImageOptim currently handles JPG, PNG and GIF files and, depending on the settings you use, shaves off between 15% and 60% in filesize. Great for bandwidth and great for users, especially on mobile.
      This module handles the part of uploading images to ImageOptim via their official API, downloading the optimized version and storing it alongside the original image.
       

       
      Download & Info
      GitHub / Module directory / Readme / Usage
       
      Why ImageOptim?
      There are other image optimization services out there, some of them free, that have outstanding ProcessWire modules. A few things make ImageOptim the best tool for most of my customers: It's not free, i.e. it will probably be around for a while and offers support. However, it's cheaper than some of the bigger competitors like Cloudinary. And it does PNG compression better than any of the free services out there, especially those with alpha channels.
       
      Installation
      Install the module like any other ProcessWire module, by either copying the folder into your modules folder or installing it via the admin. See above for downloads links on GitHub and in the module directory.
       
      Requirements
      To be able to upload images to the service, allow_url_fopen must be set on the server. The module will abort installation if that's not the case.
      I have only tested the module on ProcessWire 3.x installations. I don't see why it shouldn't work in 2.x, if anyone wants to try it out and report back.
       
      ImageOptim account
      To compress images, you first need to sign up for an ImageOptim account. They offer free trials to try the service.
       
      Usage (manual optimization)
      Images can be optimized by calling the optimize() method on any image. You can pass an options array to set ImageOptim API parameters.
      $image->size(800,600)->optimize()->url $image->optimize(['quality' => 'low', 'dpr' => 2]) // Set quality to low and enable hi-dpi mode
      Automatic optimization
      The module also has an automatic mode that optimizes all image variations after resizing. This is the recommended way to use this module since it leaves the original image uncompressed, but optimizes all derivative images.
      $image->size(800,600)->url // nothing to do here; image is optimized automatically
      To change compression setting for single images, you can pass an options array along with the standard ImageResizer options. Passing false disables optimization.
      $image->size(800, 600, ['optimize' => 'medium']) $image->size(800, 600, ['optimize' => ['quality' => 'low', 'dpr' => 2]]) $image->size(800, 600, ['optimize' => false])
      For detailed usage instructions and all API parameters, see the usage instructions on GitHub.
       
      Filenames
      Optimized images will be suffixed, e.g. image.jpg becomes image.optim.jpg. You can configure the suffix in the module settings.
       
      Roadmap
      Asynchronous processing. Not really high on the list. Image variations need to be created anyway, so waiting a few seconds longer on first load is preferable to adding complexity to achieve async optimization. Optimize image variations created by other modules. CroppableImage comes to mind. I don't use any of these, so if somebody wants to help out and submit a pull request — all for it! Add a dedicated page in the setup menu with a dashboard and detailed statistics. ImageOptim's API is very barebones for now, so not sure if that's feasible or even necessary.
      Stability
      I've been using this module on production sites for some time now, without hiccups. If you do notice oddities, feel free to comment here or investigate and submit PRs.
