如何在laravel中填充select选项？来自硬编码选项

Question

我只想填充用于编辑保存在数据库中的数据的选择选项？有人能帮帮我吗？我刚刚开始学习laravel。

这里给出的代码来自create.blade.php文件，需要修改后才能编辑

<div class="input-field col s12 m6 l6 xl4 offset-xl2 ">
    <i class="material-icons prefix">person_outline</i>
    <select name="civil_status">
        <option value="" disabled {{ old('civil_status')? '' : 'selected' }}>Select a Civil Status</option>
        <option value="Married" @if (old('civil_status') == "Married") {{ 'selected' }} @endif>Married</option>
        <option value="Single" @if (old('civil_status') == "Single") {{ 'selected' }} @endif>Single</option>
        <option value="Divorced" @if (old('civil_status') == "Divorced") {{ 'selected' }} @endif>Divorced</option>
        <option value="Widowed" @if (old('civil_status') == "Widowed") {{ 'selected' }} @endif>Widowed</option>
        <option value="Seperated" @if (old('civil_status') == "Seperated") {{ 'selected' }} @endif>Seperated</option>
    </select>
    <label>Civil Status</label>
</div>

   public function edit($id)
    {
        $departments  = Department::orderBy('dept_name','asc')->get();
        $cities       = City::orderBy('city_name','asc')->get();
        $states       = State::orderBy('state_name','asc')->get();
        $genders      = Gender::orderBy('gender_name','asc')->get();

        $employee = Employee::find($id);
        return view('employee.edit')->with([
            'departments'  => $departments,
            'cities'       => $cities,
            'states'       => $states,
            'genders'      => $genders,
            'employee'     => $employee,
            'toBeEdited'   => $employee

        ]);
    }

您可以在edit.blade.php视图中执行以下操作：

<div class="input-field col s12 m6 l6 xl4 offset-xl2 ">
    <i class="material-icons prefix">person_outline</i>
    <select name="civil_status">
        <option value="" disabled {{ old('civil_status')? '' : 'selected' }}>Select a Civil Status</option>
        <option value="Married" {{ old('civil_status') == "married" || $toBeEdited->civil_status == "married" ? 'selected' : '' }}>Married</option>
        <option value="Single" {{ old('civil_status') == "Single" || $toBeEdited->civil_status == "Single" ? 'selected' : '' }}>Single</option>
        <option value="Divorced" {{ old('civil_status') == "Divorced" || $toBeEdited->civil_status == "Divorced" ? 'selected' : '' }}>Divorced</option>
        <option value="Widowed" {{ old('civil_status') == "Windowed" || $toBeEdited->civil_status == "married" ? 'selected' : '' }}>Widowed</option>
        <option value="Seperated" {{ old('civil_status') == "Separeted" || $toBeEdited->civil_status == "Separated" ? 'selected' : '' }}>Seperated</option>
    </select>
    <label>Civil Status</label>
</div>

您只需要通过您的控制器将要编辑的模型传递给您的视图，如下所示：

function edit($id)
{
    return view('edit', [
        'toBeEdited' => YourModel::find($id),
    ]);
}

或者你可以在你的编辑函数中使用依赖注入：

function edit(YourModel $model)
{
    return view('edit', [
        'toBeEdited' => $model,
    ]);
}

现在，您可以作为$toBeEdited变量访问视图中的model。

希望能有所帮助。
