Laravel Pluck - 试图获得非对象的属性

Question

I need to select the id and name field, pass the collection to the view and iterate over it to generate options for a select. However, I am getting the following error:

Trying to get property of non-object (View: ../resources/views/layouts/app.blade.php) (View: ../resources/views/layouts/app.blade.php)

Controller

public function index()
{
    $propertyTypes = PropertyType::pluck('name', 'id');
    return view('home', compact('propertyTypes'));
}

View

@foreach($propertyTypes as $propertyType)
    <option value="{{ $propertyType->id }}">
        {{ $propertyType->name }}
    </option>
@endforeach

Table

ID  Name
1   Detached
2   Semi-detached
3   Terraced
4   Flat
5   Bungalow
6   Land
7   Park Home

Answer 1

You're using the pluck method to get the results as key-value pair but in your view you're trying to access the value as an object which is causing this error.

Either you've to fetch your results as models or you've to update your view.

Option 1: Fetch results as models

public function index()
{
    $propertyTypes = PropertyType::select('name', 'id')->get();
    return view('home', compact('propertyTypes'));
}

Option 2: Iterate over collection as key-value

@foreach($propertyTypes as $id => $name)
    <option value="{{ $id }}">
        {{ $name }}
    </option>
@endforeach
