I will use the category a lot of places in my views to show, is there a way to insert somewhere so that I can use it in every view without getting this error Undefined variable: categories
At the moment i am doing it like this for every view:
$categories=Category::all();
return view('posts.create',compact('categories'));
$categories=Category::all();
return view('posts.edit',compact('categories'));
and so on..
You could do something like this in the constructor of your base controller
$categories=Category::all();
View::share('categories', $categories);
Here is more info in the laravel docs
https://laravel.com/docs/7.x/views#sharing-data-with-all-views
You need AppServiceProvider to do that on app\Providers\AppServiceProvider.php :
public function boot()
{
$categories=Category::all();
$view->with('categories', $categories);
}
@bumperbox's solution is good!
An alternative is to add a view composer with the wildcard * in your AppServiceProvider.
View::composer(['*'], function ($view) {
return $view->with([
'categories' => Category::all(),
]);
});
