Question

我是Laravel的新手，一直在努力找出处理简单任务的最佳方法。我有一个View，它有一个用于添加或编辑事件的表单（对于此示例）。当表单用于添加事件时，所有输入字段都是空白的。当它用于编辑事件时，输入由MySQL列填充。

我遇到的棘手问题是找出最佳方式告诉View我要么在验证失败时使用旧表单输入要么在我们＆＃39时使用MySQL数据;第一次打开表格进行编辑。

这就是我目前在控制器中所拥有的，它是非常长的，我确信有更好的方法，只是不确定它会是什么。

基本上，我将每个表单值分配给一个多维数组，然后将该数组返回给View。每个数组值都是有条件的 - 如果有旧的Input值，请使用它。否则，请使用表中的值。

public static function action_edit_event($id, $slug) {
    $eventDetails = Calendar::find($id);
    $event['id'] = $id;
    $event['slug'] = $slug;
    $event['title'] = (Input::old('admin_events-form-title')) ?
    Input::old('admin_events-form-title') : $eventDetails->title;
    $event['type'] = (Input::old('admin_events-form-type')) ?
    Input::old('admin_events-form-type') : $eventDetails->calendartype_id;
    $event['date_start'] = (Input::old('admin_events-form-date-start')) ?
    Input::old('admin_events-form-date-start') : $eventDetails->start_date;
    $event['allDay'] = (Input::old('admin_events-form-all-day')) ?
    Input::old('admin_events-form-all-day') : $eventDetails->day;
    $event['time-start_hour'] = (Input::old('admin_events-form-time-start_hour')) ?
    Input::old('admin_events-form-time-start_hour') : (($eventDetails->start_time != null) ?
                                    date("H", strtotime($eventDetails->start_time)) : '');
    $event['time-start_minute'] = (Input::old('admin_events-form-time-start_minute')) ?
    Input::old('admin_events-form-time-start_minute') : (($eventDetails->start_time != null) ?
                                    date("i", strtotime($eventDetails->start_time)) : '');
    $event['date_end'] = (Input::old('admin_events-form-date-end')) ?
    Input::old('admin_events-form-date-end') : $eventDetails->end_date;
    $event['time-end_hour'] = (Input::old('admin_events-form-time-end_hour')) ?
    Input::old('admin_events-form-time-end_hour') : (($eventDetails->end_time != null) ?
                                    date("H", strtotime($eventDetails->end_time)) : '');
    $event['time-end_minute'] = (Input::old('admin_events-form-time-end_minute')) ?
    Input::old('admin_events-form-time-end_minute') : (($eventDetails->end_time != null) ?
                                    date("i", strtotime($eventDetails->end_time)) : '');
    $event['description'] = (Input::old('admin_events-form-description')) ?
    Input::old('admin_events-form-description') : $eventDetails->description;
    return View::make('admin.event-post')->with('event', $event);
}

视图中的表单..

{{ Form::open('admin/events/event', 'POST', array('id' => 'admin_events-form')) }}
    <fieldset>
        <legend>Event Details</legend>
        <p>
            {{ Form::label('admin_events-form-title', 'Event Title:')}}
            {{ Form::text('admin_events-form-title', isset($event) ? $event['title'] : '') }}
            {{ $errors->first('title', '<span class="ui-state-error">:message</span>') }}
        </p>
        <p>
            {{ Form::label('admin_events-form-type', 'Event Type:') }}

        </p>
        <p class="center">
            {{ $errors->first('description', '<span class="ui-state-error">:message</span>') }}
        </p>
    </fieldset>
    {{ Form::hidden('mode', isset($event) ? 'edit' : 'add') }}
    @if (isset($event))
    {{ Form::hidden('slug', $event['slug']) }}
    {{ Form::hidden('id', $event['id']) }}
    @endif
{{ Form::close() }}

任何建议都将不胜感激。谢谢！

我假设您实际验证和存储事件的代码是在控制器中的另一个方法（即action_save_event）？

如果验证失败，我只会将视图与该方法的输入数据一起返回。

例如：

public function action_edit_event($id, $slug)
{
  $eventDetails = Calendar::find($id);
  $event['id'] = $id;
  $event['slug'] = $slug;
  return View::make('admin.event-post')->with('event', $event);
}

public function action_store_event($id, $slug)
{
  // Validate the input data
  // If valid store to the database
  // Else, assemble $event from the old input data
  $event['id'] = $id;
  $event['slug'] = $slug;
  $event['title'] = Input::old('admin_events-form-title');
  $event['type'] = Input::old('admin_events-form-type');
  // ...
  // Return the view with $event
  return View::make('admin.event-post')->with('event', $event);
}

根据验证，在显示表单时使用表中的存储值或提交的表单数据
