Validation unique values from array

Question

I have a {{ Form::textarea('name') }} for add an array.

In a controller I use:

$input = $request->all();
$name = explode(PHP_EOL, $input['name']);

$this->validate($request, [
    'name' => Rule::unique('table1')->where(function ($query) {
        global $name;
        $query->whereIn('name', $name);
    })
]);

But it does not work. How to validation array for unique values?

Sorry for my english.

Doesn't work because name is a single string, not an array — MohamedSabil83

Just a tip : if you want to use $name inside of the anonymous function, add use ($name) like this : function($query) use ($name){ // ... } — Drown

The easy approach. If you want better control and ability to use this with the validate method then i'd suggest creating a custom validation rule.

$data = [
    'name' => explode(PHP_EOL, $request->input('name'))
];

$validator = \Validator::make($data, [
    'name.*' => 'unique:table1,name',
]);

if ($validator->fails()) {
    // Handle failed logic
}

Sorry. Maybe you know. I use return redirect('...')->withErrors($validator) ->withInput(); for output errors. It output errors as The name.0 has already been taken. How to show the value instead of name.0.
