Hi, I am new to Laravel and have a issue passing valu from a view to a controller and I get Missing required parameters for [Route: / xxxxx error. Bellow is my code. Why am I getting this error? View: <a href="{{ route('/first_letter', ['f_letter'=>'A']) }}">A</a> Route: Route::get('/first_letter/{$f_letter}','ProductController@first_letter')->name('/first_letter'); Controller: public function index() {
$products=DB::table('products') ->join('families','products.id_family','=','families.id') ->select('products.name') ->where('products.name','like',$this->letter.'%') ->get(); return view('product.index', compact('products'));
