Laravel L5 complex validation of array data

Question

In my application, have a form that could (theoretically) have infinite task and I want to define a validation rule in my Request that checks that none of them is equals to each others:

From:

<select name="task[1][id][]" class="form-control">

..

<select name="task[2][id][]" class="form-control">

..
..

<select name="task[n][id][]" class="form-control">

Since I am still not familiar enough with Laravel validations, I was naiv and tried things like:

'task[1][id][]' => 'different:task[2][id][]', 'task[2][id][]' => 'different:task[1][id][]'

or:

'task[1][id][*]' => 'different:task[2][id][*]', 'task[2][id][*]' => 'different:task[1][id][*]'

or:

'task[*][id][*]' => 'different:task[*][id][*]'

I do not get any error, but the validation always passes. I am pretty sure, that there is a good way to get this thing running, but I think that I am on the wrong way..

edit: (additional information as requested)

<select name="task[1][id][]" class="form-control">
      <option value="">&nbsp;</option>
      @foreach ($users as $user)
          <option value="{{ $user->id }}">{{ $user->email }}</option>
      @endforeach
</select>

<select name="task[2][id][]" class="form-control">
      <option value="">&nbsp;</option>
      @foreach($users as $user)
         <option value="{{ $user->id }}">{{ $user->email }}</option>
       @endforeach
</select>

For now, I am using "hardcoded" <select>. Nothing special...

  'task.*.id.*'=>'distinct'
]

'task.*'=>'distinct' but also 'task.id.*' => 'distinct'is not working.

show your view code, your select form code, this should work fine for arrays

Sohel0415 Over a year ago

show your real view code, something like generating select field with foreach may be,, or you could dd($request) and show us

Sorry to bother you again, but there is one last thing: how could I ignore "empty" ìd`?
