Laravel 9 in_array(): Argument #2 ($haystack) must be of type array, null given [duplicate]

Question

I'm working on a Laravel 9 project and I'm trying to add arrays of staff access passcodes but I keep getting this error every time I type in the correct passcode: in_array(): Argument #2 ($haystack) must be of type array, null given

Heres the code:

public function access(Request $request) 
{
    $access_pass = config('web.offlinePass');

    if (!in_array($request->pass, $access_pass))

        return back()->withErrors(['The password entered is incorrect!']);

    session()->put('admins_only', $request->pass);
    
    session()-save();

    return redirect()->route('website.dash.dash');
}

Your second parameter $access_pass in the in_array is null. Double check your web.php config. — vstruhar

From what I see, you would have to have config/web.php file and inside return ['offlinePass' => ['array', 'of', 'values']];. Variable admins_only is used in session from what I see. — vstruhar

It works, now I got this error. Call to undefined function App\Http\Controllers\save() — CryptoPath

That's a different issue. Check your route, looks like you didn't define it properly. — vstruhar

Replace your array, which has the value null with an empty array. (of course only if it is null):

in_array($request->pass, $access_pass ?? [])

you have to make sure that the variable you are checking is an array, so you can verify it with print_r($variable_name) before checking code in_array()

Pluck method return a collection, which is not an array.

$payaments = Equipment::where('vehicle_id', $id)->pluck('equipment_value')->toArray();

in this example the $access_pass = config('web.offlinePass'); not array . you check by function dd($access_pass); , for that you need to change to array by function toArray() to check is in array or not
