如何使用雄辩的laravel 5.8匹配数组内的某个值?

In validation I didn't set the product field name to unique but want to it unique in some ways like products with same user_id, I want a single user have unique products name. So did some code to match value which is product field name to an array of product names from database.

    $products = Product::find(auth()->user()->id)->get();

    foreach ($products as $product) {
        $pro_name = $product->name;
    }

    $value = Input::get('name');

    if ($value == anyOf($pro_name) {
        return false;
    }

    i assume user_id is not the primary key to your product table. so you can't use find. do it like:

    $products = Product::where(user_id, auth()->user()->id)->get();
    

    you need an array of products name. get it like this:

    $pro_name = Product::where(user_id, auth()->user()->id)->pluck('name')->toArray();
    

    to check the array for a certain key use:

    if (in_array($value, $pro_name)) {
        return false;
    }
    

    also you can do the whole thing like this:

    $value = Input::get('name');
    
    $product = Product::where(user_id, auth()->user()->id)->where('name', $value)->first();
    
    if ($product){
    return false;
    }
