如何在laravel中将数据从组合选择显示到文本字段

// 创建数据库表的迁移文件
php artisan make:migration create_selections_table --create=selections

// 在迁移文件中定义表结构
Schema::create('selections', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->timestamps();
});

// 生成模型
php artisan make:model Selection

// 在模型中定义关联关系
class User extends Model
{
    public function selection()
    {
        return $this->belongsTo(Selection::class);
    }
}

class Selection extends Model
{
    public function users()
    {
        return $this->hasMany(User::class);
    }
}

<form action="/save-selection" method="POST">
    @csrf
    <select name="selection_id">
        <option value="1">Option 1</option>
        <option value="2">Option 2</option>
        <option value="3">Option 3</option>
    </select>
    <input type="text" name="text_field">
    <button type="submit">Submit</button>
</form>

// 在控制器中处理表单提交
public function saveSelection(Request $request)
{
    $user = new User;
    $user->selection_id = $request->input('selection_id');
    $user->text_field = $request->input('text_field');
    $user->save();

    return redirect('/')->with('success', 'Selection saved successfully');
}

@foreach ($users as $user)
    <p>Selection: {{ $user->selection->name }}</p>
    <p>Text Field: {{ $user->text_field }}</p>
@endforeach
