Laravel 5.2 paginating
remove all() function, your code should be:
$content = content::paginate(10);
As suggested by Gouda Elalfy you should remove the call to all().
Explanation
The method paginate() is available on Eloquent\Builder which is what you implicitly have when you call content::paginage(10).
However content::all() returns a Collection or an array of Model, not a Builder.
Here it explains how to do it https://laravel.com/docs/5.2/paginationand based on that you should do:
1) In your controller change the line $content = content::all()->paginate(10);
to be
$content = content::paginate(10);
2) In your view you could use this
{{ $content->appends(Request::except('page'))->links() }}
This will do what you want!!
