In this tutorial im going to share how to check auth login if user login then execute the under code other wise redirect to login page.

Error: –

Attempt to read property "id" on null

Solution :-

if (Auth::check()) {
    // User is logged in
    $users = User::where('id', '=', auth()->user()->id)->first();
    // Rest of your code...

    // Place the rest of your code here
    // ...

    // Return the view based on the user's role
    if ($getting_roll_id == 1) {
        return view('pages.viewprofile', compact('slug', 'users', 'org_slug', 'getting_roll_id', 'slug_id', 'profile_user_url', 'user_id', 'get_country_name', 'get_state_name', 'get_city_name', 'gets_image', 'mobile_id', 'pay_user'));
    } elseif ($getting_roll_id == 2) {
        return view('manager/viewprofile', compact('slug', 'users', 'org_slug', 'getting_roll_id', 'slug_id', 'profile_user_url', 'user_id', 'get_country_name', 'get_state_name', 'get_city_name', 'gets_image', 'mobile_id', 'pay_user'));
    } else {
        return view('user/viewprofile', compact('slug', 'org_slug', 'users', 'getting_roll_id', 'slug_id', 'profile_user_url', 'user_id', 'get_country_name', 'get_state_name', 'get_city_name', 'gets_image', 'mobile_id', 'pay_user'));
    }
