validating inputs in Laravel 5.8

Question

I am trying to validate input quantity of an item in Laravel. How will I do this using request()->validate([])? I want to validate if the input quantity from user is greater than the quantity of item from database.

Also, is it possible to return an error message if the entered quantity is greater than the quantity from database?

Here's my validation, I know this is wrong.

public function deduct(Request $request)
{

    $item = Inventory::findOrFail($request->itemid);
    request()->validate([
        'quantity' => $item->quantity > $request->quantity
    ]);
}

I think this link will help you if you not find item https://stackoverflow.com/questions/19838978/laravel-redirect-back-with-message — mukesh kumar, Sep 10 '19 at 05:55

You can use min, max and digits_between

   $rules = ['test' => 'digits_between:2,5'];

or

   $rules = ['test' => 'numeric|min:2|max:5'];

Set $item->quantity is the minimum value.

public function deduct(Request $request)
{

    $item = Inventory::findOrFail($request->itemid);
    $validatedData = $request->validate([
        'quantity' => 'min:'.(int)$item->quantity
    ]);

}
