Populate dropdown in laravel with more than 2 attributes - php

Question

So far I know how to populate dropdown using Eloquent (and pluck) is this
public function create()
{
$items = Item::all()->pluck('name', 'id');
return view('admin.item.create', compact('items'));
}
And with this
{!! Form::select('item_id', $items, null, ['class' => 'form-control']) !!}
I can generate this
<select name="items" class="form-control">
<option value="1">Item 1</option>
<option value="2">Item 2</option>
<option value="3">Item 3</option>
</select>
But now I want to create something like this
<select name="items" class="form-control">
<option value="1">Item 1 - Location</option>
<option value="2">Item 2 - Location</option>
<option value="3">Item 3 - Location</option>
</select>
I can only use pluck with 2 attributes. But now I want it to display 3 attributes. How do I do that? I'm using Laravel 5.3 by the way. Thanks for the help.

Answer 1

You have an array like [1=> "something",2=>"else"]. So you task is to either iterate the array and edit the values or select the the locations from the database and the use foreach or array_filter
So something like the following:
$items=[];
foreach(Item::all() as $item){
$items[$item->id] = $item->name . " - " . $item->location->name; // build string to display here
}
Edit:
Your comment said location is at the same table so it would look like...
$items=[];
foreach(Item::all() as $item){
$items[$item->id] = $item->name . " - " . $item->location; // build string to display here
}

Pluck location also
public function create()
{
$items = Item::all()->pluck('name', 'id', 'location');
return view('admin.item.create', compact('items'));
}
Generate like this
<select name="items" class="form-control">
#foreach($items as $item)
<option value="{{ $item->id }}">{{ $item->name }} - {{ $item->location }}</option>
#endforeach
</select>

Best way to create list of array is.
public function create(){
$items = Item::where('id','<>','')->lists('name', 'id');
return view('admin.item.create', compact('items'));}
