Array on where clause laravel - laravel

Question

I have an array of values I want to pass into my where clause when querying a model
How do I achieve this?
I have $categorypro variable getting below array in this format
Array
(
[0] => 4
[1] => 8
[1] => 5
)
Currently I am doing this in controller but not getting proper data some category
Below is my controller code :
function filter_each_video(Request $request){
if(request()->ajax()){
if($request->has('categorypro') && ($request->get('categorypro')!= null)){
$categorypro = $request->get('categorypro');
$item = Item::whereIn('category_id', $categorypro)->get();
}
}
}
If any one have better idea then let me know . Or something wrong in this then give some idea

Answer 1

Generally you would use a 'whereIn' clause:
MyModel::whereIn('attribute', ['value', 'value', 'value'])
->get();

Answer 2

First, you already have the $request in your method, so you don't need to call request(). Always make sure you're validating any data you're using from a request. Second, you can get the query first, then filter it if necessary depending on the post data. Only put your whereIn filter inside the if block.
public function filter_each_video(Request $request)
{
$request->validate([
'categorypro' => 'nullable|array',
'categorypro.*' => 'int'
]);
$query = Item::query();
if ($request->ajax() && $request->categorypro) {
$query->whereIn('category_id',$request->categorypro);
}
$categories = $request->categorypro
? Category::whereIn('id',$request->categorypro)->get()
: null;
$items = $query->get();
return view('myview',compact('items'));
}
