Laravel - Routing to update error - php

Question

I encounter a error:
Some mandatory parameters are missing ("users") to generate a URL for route "users.update".
I have this set on my view:
{{ Form::open( array('action' => array('UsersController#update')) ) }}
<div> {{ Form::label('username', 'Username:') }}
{{ Form::text('username', $user->username , array('class' => 'form-control')) }}</div>
<div> {{ Form::label('email', 'Email Address:') }}
{{ Form::text('email', $user->email , array('class' => 'form-control')) }}</div>
<div> {{ Form::label('new_password', 'New Password:') }}
{{ Form::text('new_password', '', array('class' => 'form-control')) }} </div>
<div> {{ Form::label('old_password', 'Old Password:') }}
{{ Form::text('password', '', array('class' => 'form-control')) }} </div>
{{ Form::submit() }}
{{ Form::close() }}
I also have a function in my controller linked to update:
public function update() {
return 'This is an update';
}
And finally, when I check all the routes available in Artisan command, I found that the update has a route to: users/{users}
What's wrong with my codes? I'm trying to update a user and it throws this error.

Answer 1

Your route is defined in a way to expect a variable $users to be passed. because of the: {users}
Instead, you should define it like:
Route::post('users/update', 'UsersController#update');
and then in your function update() get the post variable by:
$users_data = Input::get();
OR
if you want to keep the parameter, redefine the form by passing additional parameter:
{{ Form::open( array('action' => array('UsersController#update', $id)) ) }}

Answer 2

The way you are opening the FORM, it is needs a route paramenter. If you dont want to pass parameters, just use the following:
{{ Form::open(array('action' => 'UsersController#update')) }}
Instead of:
{{ Form::open( array('action' => array('UsersController#update')) ) }}

Answer 3

Even when you're setting a action, you may still need a route for it. I STRONGLY recommend you to always use CLEARED DEFINED routes to your controllers. See if the Resource Controllers helps you, in case you don't wanna to define every god damm route (I DON'T).
And, finally answering your question: I think a
{{ Form::open(array('action' => 'UsersController#update')) }}
...may solve your problem. Hope it helps. Sorry for my bad english! :D
