php - Laravel view rendering issue

Solution:

I imagine you want to callshowList from theindex function and not from the routes. If so, there's no return action from theindex function. In order to make it work, you need to return within theindex function what is returned fromshowList function, otherwise, the View will not be rendered. Try changing yourindex function to:

public function index($action = '', $id= '') {
    switch ($action) {
        case ''     :
        case 'list' : 
                    return $this->showList();
        case 'add'  : 
                    return $this->addCategories();
        case 'edit' : 
                    return $this->editCategories($id);
    }

}
Copy code

Solution:

here is the problem...remove the / from the return view line

public function showList($id_category =''){
    echo "testing";
    return View::make('welcome'); //it does not work here
Copy code

}
