HybridAuth and running it in a 3rd party script

Hello,

I've run in to a bit of a hurdle. I can get this snippet running when using the standard path, document and set up, eg, website.com/index.php?id=19

However, I am trying to run this from a different location, using custom files from a different path so I can access the ModX db - and do cool stuff. eg, website.com/test/index.php

I've done minimalist test file example, and I'm a little stuck.
This is the code I've put in my /test/index.php: (This is not to be confused with the main modX /index.php file. )

<?php
session_start();
$sess_id = session_id();

require_once('../config.core.php');
require_once MODX_CORE_PATH.'model/modx/modx.class.php';
$modx = new modX();
$modx->initialize('web');
$modx->getService('error', 'error.modError');

// run HybridAuth (add your config params to the array)
$HybridAuth = $modx->runSnippet('HybridAuth', array('providers' => "Facebook")); 
 
echo $HybridAuth;

?>

So what I'm getting loaded is just a page with "You can authorize on site with: " and a link that says "Facebook" (no pretty icon like last time), and this result in the source code:

You can authorize on site with: 
<br/>
<a href="http://www.website.com/test/index.php?hauth_action=login&provider=Facebook" class="ha-icon facebook" rel="nofollow" title="Facebook">Facebook</a>

When I click on the link, I just get the url linking back to itself, with the parameters growing with more "&hauth_action=login&provider=Facebook" appended to the page url and the link url.

I'd also updated my FB dev account to test this out too, and set the URL to the /test/ path, but it doesn't want to work either.

Any thoughts?

I noticed that in "normal" document that the css code gets put in automatically in the head code.
Am I missing something else that needs to be triggered, such as the plugin?

Cheers,
Steve

Righto.

I'm a little less frustrated now. This is for others in a similar boat:

<?php

error_reporting(E_ALL);
ini_set('display_errors', '1');
session_start();
$sess_id = session_id();

require_once('../config.core.php');
require_once MODX_CORE_PATH.'model/modx/modx.class.php';
$modx = new modX();
$modx->initialize('web');
$modx->getService('error', 'error.modError'); 

// Shows all the stuff about who you are logged in as etc
if ($modx->context->key != 'web' && !$modx->user->id) {
        if ($user = $modx->getAuthenticatedUser($modx->context->key)) {
                $modx->user = $user;
                $modx->getUser($modx->context->key);
        }
}

if ($modx->user->isAuthenticated($modx->context->key)) {
        if (!$modx->user->active || $modx->user->Profile->blocked) {
                $modx->runProcessor('security/logout');
                //$modx->sendRedirect($modx->makeUrl($modx->getOption('site_start'),'','','full'));
                $modx->sendRedirect($modx->getOption('ha.startURL'));
                
        }
}

// end showing logged in stuff 

if (!empty($_REQUEST['hauth_action']) || !empty($_REQUEST['hauth_start']) || !empty($_REQUEST['hauth_done'])) {
        
        if (!$modx->loadClass('hybridauth', MODX_CORE_PATH . 'components/hybridauth/model/hybridauth/', false, true)) {return;}
        $config = !empty($_SESSION['HybridAuth'][$modx->context->key])
                ? $_SESSION['HybridAuth'][$modx->context->key]
                : array();
        $HybridAuth = new HybridAuth($modx, $config);

        if (!empty($_REQUEST['hauth_action'])) {
                switch ($_REQUEST['hauth_action']) {
                        case 'login':
                                $HybridAuth->Login(@$_REQUEST['provider']);
                                break;
                        case 'logout':
                                $HybridAuth->Logout();
                                break;
                }
        }
        else {
                $HybridAuth->processAuth();
        }
} 

//$css = $modx->getOption('ha.frontend_css');
//echo $css;

 ?>
  <link rel="stylesheet" href="/assets/components/hybridauth/css/web/default.css" type="text/css" />
<?php
  
// run HybridAuth (add your config params to the array)
$HybridAuth = $modx->runSnippet('HybridAuth', array('providers' => "Facebook")); 
 
echo $HybridAuth;

?>

You'll notice that the CSS is hardcoded, as I don't know how (I'm sure someone can assist with it), but it comes out looking like this and not compiled: [[+assetsUrl]]css/web/default.css

I couldn't get the plugin to execute and load and do what it should, instead because it was so small, I just pasted it in. It was using the "OnHandleRequest" plugin, for System, Default, 10.

This instead works.

I did however make at least one change to the main source code:

/core/components/hybridauth/model/hybridauth/hybridauth.class.php
Line: 140 (approx)

'base_url' => $this->modx->getOption('ha.startURL'),

What I was finding is that all it wanted to do was go to the start page each time, and not where it had begun. So I made a new System Setting in the 'web' context called "ha.startURL" with the value of "http://websitename.com/test/".

So far so good. I'm sure there will be a couple more tweaks out there to make, but wanted to share.

Just remember the little gotachas. I had one, of putting in the wwws vs not put them in. The session thinks it's a different site, and when you are calling it from Facebook in your Dev account, it must be the same. [ed. note: vrdriver last edited this post 12 years, 11 months ago.]

I ran into a similar type issue with HybridAuth as I was developing with my modx install in a different folder to web root.

www.example.com/development/test

The login link generated by HybridAuth would be www.example.com/development/test/development/test/?hauth_action=login&provider=Google

Resulting in landing on the error page when trying to log in. Setting the &loginResourceId and &logoutResourceId pages in the call resolved my problem.

[[!HybridAuth?providers=`Google`
&loginResourceId=`374`
&logoutResourceId=`372`
]]

Yeah, I have to do it this way, because I'm outside of the MODX "CMS path". I want the goodness of the CMS and the user permissions, but still need full control and custom files. This is what I LOVE about MODX.

I'm basically doing something like this

/root/
     /assets/
     /core/ 
     /test/

Which is making it a little more complex than just storing the resource IDs. I was nearly ready to start using cookies and things for storing URL variables, as my /test/ path is using an index file that must be referenced, and is a unique parameter, but fortunately FB returns back to the path it came from with all of the parameters and values. I was very happy about that discovery.

So, basically this path index.php?steve=reallycool has the hybridauth code, a user authenticates with FB, and returns to the same page, with only one slightly different parameter: index.php?steve=reallycool#_-_
And this I can live with.

I'm just glad I'm not the only one in the boat.
