html - Trying to get property 'name' of non-object when trying to click next page using pagination

Question

I get an error saying "Trying to get property 'name' of non-object" when I tried to click on next page using pagination.

Here is my Controller:

$websites = Website::all();
    $menu = Menu::with('categories')->whereHas('categories', function ($query) {
        $query->where('slug', request()->category);
    })->paginate(8);

    $categories = Category::all();
    $categoryName = $categories->where('slug', request()->category)->first()->name;

    return view('shopmenu')->with([
        'menu' => $menu,
        'categories' => $categories,
        'categoryName' => $categoryName,
        'websites' => $websites,
    ]);

The error is in this code:

 $categoryName = $categories->where('slug', request()->category)->first()->name;

How do I solve this?

You need to put check if you are getting any record then try to access name.

 $categoryName = $categories->where('slug', request()->category)->first();

 if ($categoryName) {
 $categoryName = $categoryName->name;
 }

Basically due to chaining when you get null in this query $categories->where('slug', request()->category)->first() and you try to access name property on null you get this error.
