Facebook strategy for Opauth

Opauth-Facebook

Opauth strategy for Facebook authentication.

Implemented based on https://developers.facebook.com/docs/authentication/

Getting started

1. Install Opauth-Facebook:

   cd path_to_opauth/Strategy
   git clone https://github.com/opauth/facebook.git Facebook

   or

   composer require opauth/facebook
   

2. Create Facebook application at https://developers.facebook.com/apps/

   • Remember to enter App Domains
   • "Website with Facebook Login" must be checked, but for "Site URL", you can enter any landing URL.

3. Configure Opauth-Facebook strategy with at least App ID and App Secret.

4. Direct user to http://path_to_opauth/facebook to authenticate

Strategy configuration

Required parameters:

<?php
'Facebook' => array(
	'app_id' => 'YOUR APP ID',
	'app_secret' => 'YOUR APP SECRET'
)

Even though fields is an optional configuration parameter for Opauth-Facebook, for most cases you would like to explicitly define it. It should be defined in a comma-separated string.

Refer to Facebook Fields Reference for list of valid fields.

facebook's Issues

Add email scope to defaults

Since Facebook has changed Email as explicit param to be specified while making an API call. We should add it as default scope,

Change,

public $defaults = array(
    'redirect_uri' => '{complete_url_to_strategy}int_callback'
);

to

public $defaults = array(
    'redirect_uri' => '{complete_url_to_strategy}int_callback',
    'scope' => 'email'
);

Fatel Error : Config Parameter expected

Error: FacebookStrategy config parameter for "xxxxxxxxxxxxxxx" expected.

Any idea why I am getting this error?

Incorrect GET variables

The class uses

$error = array(
    'provider' => $this->strategy['provider'],
    'code' => $_GET['error'],
    'message' => $_GET['error_description'],
    'raw' => $_GET

But Facebook seems to return 'error_code' and 'error_message'...

Facebook folder is ignored by git

Hello...

I have encountered this problem while using Opauth Facebook.

I cloned this repository into the Strategy folder just like what is instructed in README file.

However, the Facebook folder is seemed to be ignored by git.
I was not able to push it into my project.
I tried checking gitignore files, but it is not included in gitignore.

Can anyone help me regarding this issue? Thank you so much in advance!

Still alive?

Hello,

I am sorry to be the one asking it, but... is this strategy still working? Last update was 3 years ago.

Thank you,
Guido

Latest

Is this currently working? I don't seem to be able to get it running and see it was last updated 2 years ago? .. So is this the latest branch?

Documentation bug: setting variables

This code being posted at the top of the class PHP file doesn't work:
'Facebook' => array(
'app_id' => 'YOUR APP ID',
'app_secret' => 'YOUR APP SECRET'
)

Second connect

If we try to connect for the second time using Opauth for Facebook (when we already connected), to extend access token. Facebook won't return expires value.

FacebookStrategy.php:76 will return an error because expires is not set in results

EDIT: Wrong repo!

EDIT: Wrong repo, sorry!

Process 'middle_name' element

Some people have a middle_name, like me.

First name: Kees
middle name: van
Last name: Dieren

When I login using Facebook, the 'info' hash contains:

        [info] => Array
            (
                [name] => Kees van Dieren
                [image] => ...
                [nickname] => ....
                [first_name] => Kees
                [last_name] => Dieren
                [urls] => Array
                    (
                        [facebook] => ...
                    )

            )

The middle_name is not present in info.

Solutions could be:

• add a middle_name key to info hash
• add middle_name as suffix to last name, e.g. making last_name 'van Dieren'

'Undefined index: error' in FacebookStrategy.php:112

I just found this in my logs. Luckily, I logged the callback url so I guess fixing it should not be an issue.

"/opauth/facebook/int_callback?error_code=2&error_message=Sorry%2C+this+feature+isn%27t+available+right+now%3A+An+error+occurred+while+processing+this+request.+Please+try+again+later."

Use of this from within Closure

Seems there are two spots where you're using $this inside the closures.

Please use $that = $this; and then use($that) on the Closures.

Undefined index: expires @ line 77

After login i have this error :

For info, Twitter and Google opauth's work fine

Intermittent warning with file_get_contents() OpauthStrategy.php, line 402

Hello,

I have a strange problem using OpAuth's Facebook strategy.

The strategy works correctly, I can connect via Facebook, but sometime I get this warning:

Error keys for Error-Callback wrong

The FacebookStrategy::int_callback() method fails when there is an error as the response keys are still at the old API. This concerns v0.3 of this package. PR ahead.

Undefined index when Facebook gives an error

I recently discovered that this strategy does not work properly when Facebook returns an error.

The strategy expects URL parameters of "error" and "error_description" for its error information. However it seems that they have recently modified the parameter names, causing this error. So I needed a few modifications like below to get it fixed.

I hope it helps you :)

Cheers.
