Laravel sort Relationship - php

Question

How can I sort my result with related tables?
I have this tables: Clients and Managers (users table)
Client.php
<?php
class Client extends Eloquent {
protected $table = 'clients';
public function Manager(){
return $this->belongsTo('User','manager','id');
}
public function Transaction(){
return $this->hasMany('ClientTransaction','client','id');
}
}
Users.php (default Laravel's model)
My question is how can I query table clients to be sorted by Manager's name.
Here is my code so far:
public function getClients() {
// Sorting preparations
$allowed = array('name','contact','money');
$sort = in_array(Input::get('sort'), $allowed) ? Input::get('sort') : 'name';
$order = Input::get('order') === 'desc' ? 'desc' : 'asc';
// Get Clients from DB
if($sort == 'contact'){
$clients = Client::with(array('Manager' => function($query) use ($order) {
$query->orderBy('name', $order);
}));
} else {
$clients = Client::orderBy($sort, $order)->with('Manager');
}
// Filters
$cname = null;
if(Input::has('cname')){
$clients = $clients->where('name', Input::get('cname'));
$cname = '$cname='.Input::get('cname');
}
// Pagination
$clients = $clients->paginate(25);
// Return View
return View::make('pages.platform.clients')
->with('clients', $clients);
}
If I try to sort by Name it sorts OK by Clients name but if I try to sort by contact it needs to sort by User's (Manager's) name.

Try this.
$clients = Client::join('users as manager', 'manager.id','=','clients.manager')
->orderBy('manager.name', $order)
->select('clients.*') // avoid fetching anything from joined table
->with('Manager'); // if you need managers data anyway
Put this into your if statement if($sort == 'contact'){ /***/ }
