Laravel PHP 8 刀片 -> 获取所有父表记录的列表，将它们列在 select 元素中并根据外文ID选择记录->名称

Question

So to break that title down... I have 2 tables -> bosses (parent table) & employees (child) bosses hasMany employees and employees hasOne boss

What I need to accomplish is to list all the bosses in an element and "select" the current boss. And if I change the boss from the list, it should change the id of the element to the new selection.

@foreach ($bosses as $boss) 
  <option value="{{ $boss->id }}" {{ $boss->id == ($employee->boss_id) ? 'selected' : '' }}>
    {{ $boss->full_name }}
  </option>
@endforeach

With the above code I'm getting all of the $publishers listed by name but it is not selecting the the boss associated the the boss_id foreign key.

Thanks in advance!!!

You could use the helper method old() for this.

For example:

<select name="boss_id>
@foreach ($bosses as $boss) 
<option value="{{$boss->id}}" {{ old('boss_id', $boss->id)==($employee->boss_id) ? "selected" : '' }}>
