I am using ajax to retrieve data from my database into a select box. When i select a group, it should displays it contents respectively.

When i try to display the form, it says Undefined variable: packages but i have return package in the view in my controller.

Is there anything i am missing out ?

PackageController

 public function create()
    {
        $groups = Group::all();
       $selectedGroup = $group->pluck('id')->toArray();
        return view('group.detail',compact('selectedGroup','groups'));
    }


    public function getpackages($id)
   {
    $groups =  Group::findOrFail($id);
    $packages= $groups->packages;

    return view('group.detail',compact('packages'));
    return $id;

   }

group.details.blade.php

<div class="input-group control-group after-add-more">

          <div class="form-group">
          <!-- <label for="select" class="col-lg-2 control-label">Select Item</label> -->
          <div class="col-lg-10">
          <select class="form-control" id="group" name="group[]" mulitple>
          @foreach($groups as $group)
          <option value="{!! $group->id !!}" @if(in_array($group->id, $selectedGroup)) selected="selected" @endif >
                         {!! $group->name!!}
          </option>
              @endforeach
          </select>


          </div>


          </div>


          <div class="form-group">
          <!-- <label for="select" class="col-lg-2 control-label">Select Item</label> -->
          <div class="col-lg-10">
          <select class="form-control" id="remove_select" name="packages" mulitple>
          @foreach($packages as $package)
          <option value="{!! $package->id !!}" >
                         {!! $package->name!!}
          </option>
              @endforeach
          </select>



          </div>


          </div>


<script>
 $('#category').change(function(e)
 {
 e.preventDefault();

$y = $(this).val();
  alert($y);

$.ajax
 ({
 url: '{{ url('getpackages') }}/'+$y,
 type: 'GET',
 dataType: 'json',
 success: function(data)
 {
 console.log(data);
 }
 });
 });
 </script>

Both of your controller actions are using the same view, but neither of them are passing in all of the values that the view expects. When the create controller action loads the view, it does not define the $packages variable, which is why you are getting that notice.

You need to break your view into two separate views: One for the create controller action and one for the getpackages controller action.

I think the underlying issue here is that you are not treating your initial request and your ajax request separately.

Break view into two seperate views? How is that done as i am new to this
@LearnProgramming You need two separate blade templates, not one.
Then i would have to find a different way because i can't have separate views with what i want to achieve
@LearnProgramming There is definitely a higher level issue here that I don't have enough context to address. The immediate issue is that you are trying to combine two separate views into one blade template. That will not work. Your initial request and your ajax request are two entirely separate things and need to be treated as such.
I actually want them in the same controller. So when i select a group, it's content is displayed in another select box below
