函数类似于__construct函数，但是对于LARAVEL上的特定函数

Question

function like __construct function but for specific function.

my route

Route::resource('form00', 'Form00Controller');
Route::resource('form001', 'Form001Controller');
........ and more

my __contsruct in Form00Controller

public function __construct()
    {
        $this->validate(request(), [
            'projectName' => 
                array(
                    'required',
                    'regex:/(^([a-zA-Z]+)(\d+)?$)/u'
                )
        ];
    }

my another Form00Controller function

    public function create()// this function and another not effected
    {
        return view('form00.create');
    }

    public function store(Request $request)//__construct just for this function
    {

        $requestData = $request->all();

        Form00::create($requestData);

        return redirect('form00')->with('flash_message', 'Form00 added!');
    }

i need validate just for function store and not change that function.

This is the perfect example for Custom Form Requests you can follow this tutorial

Basically you'll end up with

public function store(StoreFormFormRequest $request)//__construct just for this function
    {

        $requestData = $request->all();

        Form00::create($requestData);

        return redirect('form00')->with('flash_message', 'Form00 added!');
    }

And you'll have a StoreFormFormRequest class into app/Http/Requests which will be something like

class StoreFormFormRequest extends FormRequest {

    public function rules() {
        return [
            'projectName' => 'required|regex:/(^([a-zA-Z]+)(\d+)?$)/u'
        ]    
    }
}

Validation will be triggered automatically and, if it passes, the controller's code will be executed.
