error like "Object of class std Class could not be converted to string"

Question

This is my controller

function index()
    {
        $name_list = DB::table('customers')
            ->groupBy('first_name')
            ->get(); 
      $name_list2 = DB::table('customers')
      ->where('first_name', $name_list)->first();

     return view('dynamic_field')->with('name_list2',$name_list2); 
    }

This is my view i am retriving this in javascript.

@foreach($name_list2 as $name)
        '<option value="{{ $name->first_name}}">{{ $name->first_name }}</option>'+
        @endforeach

You are using first().It will take only one entry..So don't need to use foreach() in view.foreach used when you have a collection to print.. — Jithesh Jose

check the answer..if you are passing $name_list to view,you could have to use foreach()..But in case of $name_list2 no need of foreach() — Jithesh Jose

You don't need to foreach $name_list2 as this is a single record being fetched from the database as per your query.

You can try this without using foreach:

{{ $name->first_name}}

Hope it helps!

What are you trying to achieve by this query? $name_list2 = DB::table('customers')->where('first_name', $name_list)->first();

i am trying to get dynamic dependent select box through query

I am not so sure about your requirements however the where() clause of your query isn't correct.

If you can show us your desired result, it will help.

You can use $name_list2 as

@if(isset($name_list2))
  {{$name_list2->first_name}}
@endif

No need of foreach()

can you check whether the value is coming to the frontend or not.

Try var option = "<option value='"+{{$name_list2->first_name}}+"'>"+{{$name_list2->first_name}}+"</option>"; Then append option to dropdown..` $("#district").append(option); `
