Laravel 4: undefined variable error when submitting data from the view - php

Question

I'm trying building a timer app - this form should submit the time (which it does) AND the client name as populated from the database, it looks like this:
{{ Form::open(array('action' => 'TasksController#store', 'name' => 'timer')) }}
{{ Form::select('client', $client , Input::old('client')) }}
{{ Form::hidden('duration', '', array('id' => 'val', 'name' => 'duration')) }}
{{ Form::submit('Submit', array('class' => 'btn btn-primary')) }}
{{ Form::close() }}
My controller that generates this page looks like this:
public function index()
{
$client = DB::table('clients')->orderBy('name', 'asc')->lists('name','id');
return View::make('tasks.index', compact('task', 'client'));
}
I am getting a "Undefined variable: client" when I submit the form. I can't see why.
What am I doing wrong?
EDIT: the store function in my TasksController looks like this:
public function store()
{
$input = Input::all();
$v = Validator::make($input, Task::$rules);
if($v->passes())
{
$this->task->create($input);
return View::make('tasks.index');
}
return View::make('tasks.index')
->withInput()
->withErrors($v)
->with('message', 'There were validation errors.');
}

Answer 1

You are returning the View::make() from your store() function, which is not the 'resourceful' way of doing it.
Your view is expecting to have $client included in it - but because store() does not return a $client - the error is generated.
Assuming you are using a resourceful controller - your store function should look like this:
public function store()
{
$input = Input::all();
$v = Validator::make($input, Task::$rules);
if($v->passes())
{
$this->task->create($input);
return Redirect::route('tasks.index'); // Let the index() function handle the view generation
}
return Redirect::back() // Return back to where you came from and let that method handle the view generation
->withInput()
->withErrors($v)
->with('message', 'There were validation errors.');
}
