OAuth2Login for ProcessWire

A Module which give you ability to login an existing user using your favorite thrid-party OAuth2 provider (i.e. Facebook, GitHub, Google, LinkedIn, etc.)..
You can login from the backend to the backend directly or render a form on the frontend and redirect the user to a choosen page.
Built on top of ThePhpLeague OAuth2-Client lib.

Registration is not handled by this module but planned.

 
Howto Install

Install the module following this procedure:

 - http://modules.processwire.com/modules/oauth2-login/
 - https://github.com/flydev-fr/OAuth2Login

Next step, in order to use a provider, you need to use Composer to install each provider

ie: to install Google, open a terminal, go to your root directory of pw and type the following command-line: composer require league/oauth2-google

Tested providers/packages :

  •     Google :  league/oauth2-google
  •     Facebook: league/oauth2-facebook
  •     Github: league/oauth2-github
  •     LinkedIn: league/oauth2-linkedin


More third-party providers are available there. You should be able to add a provider by simply adding it to the JSON config file.


Howto Use It

First (and for testing purpose), you should create a new user in ProcessWire that reflect your real OAuth2 account information. The important informations are, Last Name, First Name and Email. The module will compare existing users by firstname, lastname and email; If the user match the informations, then he is logged in.

ie, if my Google fullname is John Wick, then in ProcessWire, I create a new user  Wick-John  with email  johnwick@mydomain.com

Next step, go to your favorite provider and create an app in order to get the ClientId and ClientSecret keys. Ask on the forum if you have difficulties getting there.

Once you got the keys for a provider, just paste it into the module settings and save it. One or more button should appear bellow the standard login form.

The final step is to make your JSON configuration file.

In this sample, the JSON config include all tested providers, you can of course edit it to suit your needs :

{
  "providers": {
    "google": {
      "className": "Google",
      "packageName": "league/oauth2-google",
      "helpUrl": "https://console.developers.google.com/apis/credentials"
    },
    "facebook": {
      "className": "Facebook",
      "packageName": "league/oauth2-facebook",
      "helpUrl": "https://developers.facebook.com/apps/",
      "options": {
        "graphApiVersion": "v2.10",
        "scope": "email"
      }
    },
    "github": {
      "className": "Github",
      "packageName": "league/oauth2-github",
      "helpUrl": "https://github.com/settings/developers",
      "options": {
        "scope": "user:email"
      }
    },
    "linkedin": {
      "className": "LinkedIn",
      "packageName": "league/oauth2-linkedin",
      "helpUrl": "https://www.linkedin.com/secure/developer"
    }
  }
}

 

Backend Usage

In ready.php, call the module :

if($page->template == 'admin') { 
	$oauth2mod = $modules->get('Oauth2Login'); 
	if($oauth2mod) $oauth2mod->hookBackend(); 
}

 

Frontend Usage
Small note: At this moment the render method is pretty simple. It output a InputfieldForm with InputfieldSubmit(s) into wrapped in a ul:li tag. Feedbacks and ideas welcome!

For the following example, I created a page login and a template login which contain the following code :


    <?php namespace ProcessWire;

    if(!$user->isLoggedin()) {

            $options = array(
                'buttonClass' => 'my_button_class',
                'buttonValue' => 'Login with {provider}', // {{provider}} keyword
                'prependMarkup' => '<div class="wrapper">',
                'appendMarkup' => '</div>'
            );

            $redirectUri = str_lreplace('//', '/', $config->urls->httpRoot . $page->url);

            $content = $modules->get('Oauth2Login')->config(
              array(
                  'redirect_uri' => $redirectUri,
                  'success_uri'  => $page->url
              )
          )->render($options);
    }


The custom function lstr_replace() :

/*
 *  replace the last occurence of $search by $replace in $subject
 */
function str_lreplace($search, $replace, $subject) {
	return preg_replace('~(.*)' . preg_quote($search, '~') . '~', '$1' . $replace, $subject, 1);
}

The module got renamed and updated a bit as its not intended to run only on the backend, but work also on frontend side.

 

- Now, the administrator can choose to activate or not the backend login buttons.

- The providers are added "dynamically". You have to simply edit a JSON config file which once saved, will show the required fields in the module settings.

 

For example the following JSON config will only provide Google as login provider :

{
  "providers": {
    "google": {
      "className": "Google",
      "packageName": "league/oauth2-google",
      "helpUrl": "https://console.developers.google.com/apis/credentials"
    }
  }
}

 

Small note for pw users :

If like me you did not know, there is another module that manages OAuth2 authentication. Feel free to use the one which suit your needs! more info there:

 

 

@jmartsch you should create a new module thread :)

Hey Horst,

I think that in the time the lib was made, Twitter was still using OAuth 1.0A - but looking at their doc (twitter) OAuth2 is now supported (?), their doc also stipulate they still use OAuth 1.0A...

https://dev.twitter.com/oauth

I will look at more closely.

Some more precisions : We can be able to code an adapter for Twitter application-only, and this is the list of what we can do with :

  • Pull user timelines;
  • Access friends and followers of any account;
  • Access lists resources;
  • Search in Tweets;
  • Retrieve any user information;

So I must assume we can get at least the email and/or the firstname/lastname or a nickname.

@horst let me know if you will think to code something about that or I will give a try.

Many thanks @flydev , for digging deeper!

I'm currently out of resources to code something like this. Was just searching for an already available solution to login via twitter.

Registration should be done via PW only, where the PW username is set to the twitter username.
(Frontend)-Login then should be done via Twitter only.

So, if we would be able to retrieve the email address too, it would be more than I currently need. :)

I quite played with their API (i am talking about Twitter here), its absolutely not possible to retrieve private information with the OAuth2 protocol (still waiting a confirmation on the twittercommunity) but no big hope here. We are forced to use the OAuth 1.a protocol for those sensible datas.

So, there I come with two propositions. I can make an exception and integrate Twitter and OAuth-1.a in this module or I publish a standalone module for Twitter login.

What do you think, a suggestion ?

@flydev: Really I'm not feeling in the right position to give suggestions here. I appreciate all the work and recherche you do here, so you should decide what is lesser work or fits better for you, for what ever reason. - If, at the end, a solution is available that let people login with their twitter account, it would be really great and is much more than there is atm. :-)

Hi @flydev ! Great plugin, works mostly like a charm! ;)

I had 2 issues tough:

1. with google, matching first- and last-name and usernames does not work with our setup (special chars in names that are not reflected in the username etc). I think, this makes the plugin somewhat unflexible. Would be great to have the option configure the matching, or at least an option to only match the users mail (checkbox in the backend). I just saw the "options" "scope" settings in your github json and wonder if this is already implemented but not documented?

2. We run our new page in a subdirectory and the redirect url is wrong (this is more of a process-wire issue since its not easy to get the absolute urls from the api) this results in path being present twice in the redirect url:

Problem: urls()->root + urls()->admin = //domain.com/path/ + /path/admin/ > //domain.com/path/path/admin/

This  solution would be the following:

// inside init()
$this->backendUrl = pages()->get('path="'.str_replace(urls()->root, '', urls()->admin).'", include=all')->httpUrl;

 

Keep up the great work!

@noelboss hey, glad you like it.  Thanks for the fix ! I will merge your PR today.

 

About the issue #1, I will try to implement it the next week-end. Lacking time here.

For the Github scope option, I also need to make it more flexible. The thing is that with Github, if we don't specify the scope, we can only get a public email, and only if the user has set his email "public", which by default is set to hidden, so its impossible to use email address to identify users, and I assume that most users don't want to set their email public..

And about the issue you posted on Github, I think I have already made this modification on my local dev module. I will check that at the same time as the "firstname/lastname" order issue.

@rareyush  sorry, its a custom function, you can copy paste the code in _func.php or where you want :

 

/*
 *  replace the last occurence of $search by $replace in $subject
 */
function str_lreplace($search, $replace, $subject) {
	return preg_replace('~(.*)' . preg_quote($search, '~') . '~', '$1' . $replace, $subject, 1);
}

Hi @quickjeff

It should work out of the box. Just put the code after the LoginRegister execute() function call, done.

      Hi! I've created a small Inputfield module called InputfieldFloatRange which allows you to use an HTML5 <input type="range" ../> slider as an InputField. I needed something like this for a project where the client needs to be able to tweak this value more based on 'a feeling' than just entering a boring old number. Maybe more people can use this so I'm hereby releasing it into the wild. 
      EDIT: You can now install it directly from the Modules directory: http://modules.processwire.com/modules/inputfield-float-range/
       
      What is it?
      The missing range slider Inputfield for Processwire. 
      What does it do?
      This module extends InputfieldFloat and allows you to use HTML5 range sliders for number fields in your templates.
      It includes a visible and editable value field, to override/tweak the value if required.  
      Features
      Min/max values Precision (number of decimals) Optional step value (Read more) Optional manual override of the selected value (will still adhere to the rules above) Configurable rounding of manually entered values (floor, round, ceil, disable) Usage
      Clone / zip repo Install FieldtypeFloatRange, this automatically installs the Inputfield Create new field of type `Float (range)` or convert an existing `Float`, `Integer` or `Text` field. To render the field's value simply echo `$page->field` Demo
      A field with Min=0, Max=1, Step=0.2, Precision=2

      Field with settings Min=0, Max=200, Step=0.25, Precision=2

       
      Todo
      Make the display-field's size configurable (will use the Input Size field setting)  Hopefully become redundant  
      Changelog
      004 (current version)
      - Make rounding of manually entered values configurable (floor, round, ceil or disable)
      - Fix small JS bug when the value-display field was not displayed
      - Update README
      003
      - Code cleanup, add some ModuleInfo data & LICENSE
      - Submit to PW Modules directory (http://modules.processwire.com/modules/inputfield-float-range/)
      002
      - Fix issue where setting the step value to an empty value created problem with validation
      - Make the display-field optional
      001
      - Initial release
       
      Thanks!

      If you like, you can also submit feature requests and suggestions for improvement. I also accept pull requests.
      ---- INITIAL POST FROM 2019-05-25 ----
      I wanted to let you know that I am currently working on a new ProcessWire module that fully integrates the Snipcart Shopping Cart System into ProcessWire. (this is a customer project, so I had to postpone the development of my other module GroupMailer).
      The new module SnipWire offers full integration of the Snipcart Shopping Cart System into ProcessWire.
      Here are some highlights:
      simple setup with (optional) pre-installed templates, product fields, sample products (quasi a complete shop system to get started immediately) store dashboard with all data from the snipcart system (no change to the snipcart dashboard itself required) Integrated REST API for controlling and querying snipcart data webhooks to trigger events from Snipcart (new order, new customer, etc.) multi currency support self-defined/configurable tax rates etc. Development is already well advanced and I plan to release the module in the next 2-3 months.
      I'm not sure yet if this will be a "Pro" module or if it will be made available for free.
      I would be grateful for suggestions and hints!
      (please have a look at the screenshots to get an idea what I'm talking about)

      Another little admin helper module...
      Template Field Widths
      Adds a "Field widths" field to Edit Template that allows you to quickly set the widths of inputfields in the template.

      Why?
      When setting up a new template or trying out different field layouts I find it a bit slow and tedious to have to open each field individually in a modal just to set the width. This module speeds up the process.
      Installation
      Install the Template Field Widths module.
      Config options
      You can set the default presentation of the "Field widths" field to collapsed or open. Field widths entered into the Template Field Widths inputfield are only applied if the Edit Template form is submitted with the Template Field Widths inputfield in an opened state. "Collapsed" is the recommended setting if you think you might also use core inputs for setting field widths in a template context. You can choose Name or Label as the primary identifier shown for the field. The unchosen alternative will become the title attribute shown on hover. You can choose to show the original field width next to the template context field width.
