Cannot get old values of multi-select dropdown in laravel blade

<div class="form-group">
  <select name="team[]" id="team" class="selectpicker" multiple>
    @foreach ($tdropdown as $tdrop =>$id) 
      <option value="{{$id}}" {{ (old("team[]") == $tdrop ? "selected":"") }}>{{$tdrop}}</option>   
    @endforeach
  </select>
</div>

@loyd I tried with your code. But still same result. The selected values doesn't come in the edit form.

I tried with this way too. But didn't work for me.

<option value="{{$id}}" {{ (collect(old('team'))->contains($id)) ? 'selected':'' }}>{{$tdrop}}</option>  

Any idea?

This will work.

<div class="form-group">
    <select name="team[]" id="team" class="selectpicker" multiple>
        @foreach ($tdropdown as $tdrop => $id) 
            <option value="{{ $id }}" {{ in_array($id, old('team')) ? 'selected' : '' }}>{{ $tdrop }}</option>   
        @endforeach
    </select>
</div>

Because you use as value $id, so you have to compare $id.

@michaloravec I tried with your code. But it still doesn't display the multi-select drop down selected names in the edit form. When I go to the edit mode of a user, it remains as nothing is selected from the multi-select drop down. But the multi-select drop down selected names are already saved in the database.

@mayuri0606 old() is used for getting selected values when you validation fails.

If you want to get selected from your database you need to compare it with that data in the database.

<div class="form-group">
    <select name="team[]" id="team" class="selectpicker" multiple>
        @foreach ($tdropdown as $tdrop => $id) 
            <option value="{{ $id }}" {{ $employee->teams->contains($id) ? 'selected' : '' }}>{{ $tdrop }}</option>   
        @endforeach
    </select>
</div>

But the multi-select drop down selected names are already saved in the database

the names are stored or the ids?

You have to compare if the model contains the select element that you are currently iterating over

it will only work if you are comparing the same things, keys or values.

@michaloravec

Wow.. your answer is superb. It works perfectly. Thanks a million.

but if validation fails (elsewhere) then the select list will revert to its previous values because you don't use the old helper

@snapey Yes, you are right.

@mayuri0606 This is the combination with old when your validation fails.

<div class="form-group">
    <select name="team[]" id="team" class="selectpicker" multiple>
        @foreach ($tdropdown as $tdrop => $id) 
            @if (old('team'))
                <option value="{{ $id }}" {{ in_array($id, old('team')) ? 'selected' : '' }}>{{ $tdrop }}</option>   
            @else
                <option value="{{ $id }}" {{ $employee->teams->contains($id) ? 'selected' : '' }}>{{ $tdrop }}</option>
            @endif 
        @endforeach
    </select>
</div>

Once again thank you so much @michaloravec . It works fine in validation fails.

@snapey & @michaloravec - Both of you are marvelous. Thumbs up.

its simpler than that, you can pass the teams as the second parameter to old

more like

<option value="{{ $id }}" {{ old('teams',$employee->teams)->contains($id) ? 'selected' : '' }}>{{ $tdrop }}</option>

but I cant remember if old returns a collection or plain array. It may be you have to use array method rather than contains

This is cleaner and better way:

{{ ( in_array($id, old('team')?: [])) ? 'selected' : '' }}

because in_array expect array and when in first place you haven't any old values the old() will return null which is not in_array except. to avoid this put another condition to check if old() is empty return and empty array

@peymanator how does that work with values you already have? You no longer have access to the EXISTING values.

Here the best example you can the best example to get or retain old value in multiple select option in laravel blade:
