I have the above code in my header which I include in my app.blade.php as #include('user.layouts.header') then I use app.blade.php as my layout.
How do I pass data to the header so that I can stop getting the below error if that's the reason I'm getting the error!
Undefined variable: categories (View: /home/alphy/blogEngidaFinal/resources/views/user/layouts/header.blade.php)

Answer 1

See the documentation.
You can pass params while including the header view,
#include('view.name', ['some' => 'data'])
In your case,
#include('user.layouts.header', ['categories' => ['food', 'drink', 'dessert'])
