laravel 4-call_user_func_array() - php

Question

I am trying to insert some data in database. I have created form with all fields and controller.
CarController.php
public function create() {
// load the create form (app/views/pages/create.blade.php)
return View::make('pages.create');
}
public function store() {
// store
$data = new Car;
$data->id = Input::get('id');
$data->save();
// redirect
Session::flash('message', 'Successfully created data!');
return Redirect::to('pages/cars');
}
routes.php
Route::resource('cars', 'CarController');
Route::post('desc', array('uses' => 'CarController#show'));
Route::post('create', array('uses' => 'CarController#create'));
Route::post('store', array('store' => 'CarController#store'));
create.blade.php
{{ Form::open(array('url' => 'store', 'class'=>'form-horizontal')) }}
<div class="form-group">
{{ Form::label('id', 'Vehicle ID',array('class'=>'control-label col-lg-4')) }}
<div class="col-lg-8">
{{ Form::text('id', Input::old('textId'), array('class' => 'form-control', 'placeholder'=>'Vehicle ID')) }}
</div>
</div>
{{ Form::submit('Create the Car!', array('class' => 'btn btn-primary')) }}
</div>
The problem is that it shows the following error:
expects parameter 1 to be a valid callback, no array or string given
I dont know what I have done wrong because I am new at laravel

Answer 1

You are using a resource controller and that's why you only need one route declaretion for this, like:
Route::resource('cars', 'CarController');
You have also declared following routes:
Route::post('desc', array('uses' => 'CarController#show'));
Route::post('create', array('uses' => 'CarController#create'));
Route::post('store', array('store' => 'CarController#store'));
Actually you don't need these route declarations, only use first route and this will create routes for your resource controller. For example, your routes would look like these:
Method | Url | Action | Route Name
--------------------------------------------
GET | /cars/create | create | cars.create // domain.com/cars/create using GET
POST | /cars | store | cars.store // domain.com/cars using POST
There are more, you should check the Resource Controllers. In this case, you have two methods in your controller and if you use a url like yourdomain.com/cars/create using GET method (if you navigate from browser's address bar) then it'll invoke create method and if you submit a form using POST method to yourdomain.com/cars then it'll invoke the store method and all your form fields will be available in the $_POST array and you can use Input::get('id') to get id field's value. Check the socumentation for more information.

Answer 2

change this line in the route.php file
Route::post('store', array('store' => 'CarController#store'));
to
Route::post('uses', array('uses' => 'CarController#store'));
'uses' specify which function to call when you access the route
