Grab logged_in user info in PHP template and assign variables

Question

can you help me writing this lines of code for grab in a EE template the information about a logged_in user, using php.

I'm using Vanilla Forum, and i want to use the JsConnect to pass the logged_in user information to the Vanilla Log in. Here's the guide:

Implementing Vanilla jsConnect Single-Signon on your Site

I found that libraries to include in system

PHP jsConnect client library

And the code to include in my page template is this:

<?php
require_once dirname(__FILE__).'/functions.jsconnect.php';

// 1. Get your client ID and secret here. These must match those in your jsConnect settings.
$clientID = "1234";
$secret = "1234";

// 2. Grab the current user from your session management system or database here.
$signedIn = true; // this is just a placeholder

// YOUR CODE HERE.

// 3. Fill in the user information in a way that Vanilla can understand.
$user = array();

if ($signedIn) {
   // CHANGE THESE FOUR LINES.
   $user['uniqueid'] = '123';
   $user['name'] = 'John PHP';
   $user['email'] = 'john.php@anonymous.com';
   $user['photourl'] = '';
}

// 4. Generate the jsConnect string.

// This should be true unless you are testing. 
// You can also use a hash name like md5, sha1 etc which must be the name as the connection settings in Vanilla.
$secure = true; 
WriteJsConnect($user, $_GET, $clientID, $secret, $secure);

How can i call the logged_in user info here

// 2. Grab the current user from your session management system or database here.
$signedIn = true; // this is just a placeholder

// YOUR CODE HERE.

with this

{if logged_in}
UniqueID={member_id}
Name={username}
Email={email}
PhotoUrl={photo_url}{photo_filename}
{/if}

And assign that the variables to pass to

// 3. Fill in the user information in a way that Vanilla can understand.
$user = array();

if ($signedIn) {
   // CHANGE THESE FOUR LINES.
   $user['uniqueid'] = '123';
   $user['name'] = 'John PHP';
   $user['email'] = 'john.php@anonymous.com';
   $user['photourl'] = '';
}

To generate a json file that vanilla JsConnect can read?

I think also

<?php
require_once dirname(__FILE__).'/functions.jsconnect.php';

return error in ExpressionEngine

Please somebody can tell me how can solve this.

Thank you in advance Alessio

Answer 1

If this is in a template you can just use: {member_id} {username} {email}

If you want to use all php you can use the Session class: http://ellislab.com/expressionengine/user-guide/development/usage/session.html

$user['uniqueid'] = $this->EE->session->userdata('member_id');
$user['name'] = $this->EE->session->userdata('username');
$user['email'] = $this->EE->session->userdata('email');

You'd probably be better off writing an extension that takes care of this at login than in a template.
