Yii2完整日历事件过滤无效

Question

我在Yii2框架中使用Philipp Frenzel FullCalendar并且它工作得很好。我想在选项选择的日历基础上实现基本过滤器事件，但我的代码仍然无效。帮助将受到高度赞赏。

这是在EventController中：

            $events = $this->loadEvents($dbEvents);
        } else{

下面是我在index.php中评论'events'=> $ events时的屏幕截图结果（根据你的指示）。即使我选择通过选择选项，它也不会过滤事件

如果我取消评论'events'=> $ events，它会显示所有事件，但是当我通过select选项选择时，它不会过滤事件。屏幕截图下方：

Answer 1

您使用的扩展包括最新版本FullCalendar v3.9.0。因此，请参阅下面的所有文档参考的最新API版本3。

Approach

对我来说，如果我必须实现它，我将不会使用events选项，因为我们需要在运行时基于从下拉列表中选择的选项过滤事件，更好的选择是使用eventSources选项。它提供了一种指定多个事件源的方法。使用此选项而不是events选项。您可以将任意数量的event arrays，functions，JSON feed URLs或完整的Event Source Objects放入eventSources数组中。

基于javascript的简单示例

$('#calendar').fullCalendar({
  eventSources: [
    '/feed1.php',
    '/feed2.php'
  ]
});

如果你查看Fullcalendar的文档，他们有与事件相关的部分，名称为Event Data，你可以看到各种选项以及提到的选项。

Start From

我们将首先为eventSources提供日历事件的JSON提要的URL，然后删除选项events。如果你愿意的话，我会使用你可以拥有的单一来源，但我会保持简短。

更改窗口小部件的代码，并在窗口小部件的eventSources选项下添加clientOptions选项。

<?=
\yii2fullcalendar\yii2fullcalendar::widget(array(
    'id' => 'eventFilterCalendar',
    'clientOptions' => [
        'editable' => true,
        'eventSources' => ['/schedule/filter-events'],
        'draggable' => true,
        'droppable' => true,
    ],
    'eventClick' => "function(calEvent, jsEvent, view) {
        $(this).css('border-color', 'red');
        $.get('index.php?r=event/update',{'id':calEvent.id}, function(data){
            $('.modal').modal('show')
            .find('#modelContent')
            .html(data);
        });

        $('#calendar').fullCalendar('removeEvents', function (calEvent) {
            return true;
        });

    }",
));
?>

此时，如果您要刷新日历，您将看不到之前加载的任何事件，因为之前您使用'events'=>$events加载事件但现在我们提供了一个网址源'/schedule/filter-events'（将其更改为您想要的相关controller/action使用我将使用相同的URL作为示例）。

Second Part

所以你之前加载的$events现在必须通过我们要创建的新动作加载。如果您按照GitHub页面上提供的示例进行扩展并从数据库模型加载事件，然后使用for循环进行循环以将所有事件加载到\yii2fullcalendar\models\Events()模型，然后加载该数组。

由于您没有提供有关您用于数据库存储和加载事件到日历的模型的任何细节，我假设您的模型名称是MyEvents相应地更改它和查询中的字段column_name。

/**
 * 
 * @param type $choice
 * @return type
 */
public function actionFilterEvents($choice = null) {
    Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
    $query = MyEvents::find();

    if( is_null($choice) || $choice=='all'){
        //the function should return the same events that you were loading before
        $dbEvents = $query->all();

    } else{
        //here you need to look up into the data base 
        //for the relevant events against your choice
        $dbEvents = $query->where(['=', 'column_name', ':choice'])
                ->params([':choice' => $choice])
                ->asArray()
                ->all();
    }

    return $this->loadEvents($dbEvents);
}

/**
 * 
 * @param type $dbEvents
 * @return \yii2fullcalendar\models\Event
 */
private function loadEvents($dbEvents) {
    foreach( $dbEvents AS $event ){
        //Testing
        $Event = new \yii2fullcalendar\models\Event();
        $Event->id = $event->id;
        $Event->title = $event->categoryAsString;
        $Event->start = date('Y-m-d\TH:i:s\Z', strtotime($event->date_start . ' ' . $event->time_start));
        $Event->end = date('Y-m-d\TH:i:s\Z', strtotime($event->date_end . ' ' . $event->time_end));
        $events[] = $Event;
    }
    return $events;
}

上面要注意的事情

• $choice中的actionFilterEvents参数，null作为列出第一次加载日历时所有事件的默认值。
• 将搜索到的事件从数据库加载到loadEvents()的\yii2fullcalendar\model\Events方法确实使用您将使用的相关模型字段名称而不是foreach更改MyEvents中使用的字段名称。

此时，如果您在刷新页面时完成了所有操作，则会在日历中看到加载的默认事件。

Actual part

现在，根据下拉列表的选择过滤事件。对于服务器端，我们已经完成了上面的工作，else部分将处理从数据库中过滤所有事件，方法是将所选选项与所需的列column_name进行比较（将其替换为您要与之比较的字段名称）。还有待完成的部分是客户端，我们将绑定下拉列表的onchange事件，然后主要使用fullcalendar提供的这3个methods

• removeEventSource，动态删除事件源。源中的事件将立即从日历中删除。
• addEventSource，动态添加一个事件源。源可以是一个数组/ URL /函数，就像在events选项中一样。活动将立即从此来源获取并放置在日历上。
• refetchEvents，重新获取所有来源的活动并在屏幕上重新呈现它们。

每次我们选择一个选项时，前一个eventSource被移除并添加一个新的eventSource所以如果选择schedule/filter-events?choice=all，基本上将构建url All Tech，如果选择schedule/filter-events?choice=0则构建Hendy Nugraha，依此类推。

在您已初始化窗口小部件的视图顶部添加以下javascript。

确保#select_name下方使用的选择器与您的下拉列表的实际id匹配。

$js = <<< JS

        var eventSource=['/schedule/filter-events'];

        $("#select_name").on('change',function() {

        //get current status of our filters into eventSourceNew
        var eventSourceNew=['/schedule/filter-events?choice=' +  $(this).val()];

        //remove the old eventSources
        $('#eventFilterCalendar').fullCalendar('removeEventSource', eventSource[0]);
        //attach the new eventSources
        $('#eventFilterCalendar').fullCalendar('addEventSource', eventSourceNew[0]);
        $('#eventFilterCalendar').fullCalendar('refetchEvents');

        //copy to current source 
        eventSource = eventSourceNew;
    });
JS;

$this->registerJs($js, \yii\web\View::POS_READY);

按照上面的说明执行所有操作，它将开始工作，并在您更改下拉列表中的选项时立即显示已过滤的结果。

注意：我已经使用Yii2.0.15.1和最新的可用扩展从正在运行的项目中提供了上述解决方案。

EDIT

我很惊讶你无法区分服务器端，HTML和javascript，我提供的与javascript相关的代码需要粘贴在视图中event-index在heredoc内部你必须复制粘贴它但不知何故你结束了将qavascript包装在<script>标签内并删除了heredoc？而且你在脚本标签内调用$this->registerJs()而不是<?php ?>标签？ ¯\ _（ツ）_ /¯。

你甚至没有更改var eventSource=['/schedule/filter-events']; javascript代码的URL中的控制器名称你的控制器是Event而不是schedule，我写的每一点，我假设一个模型或控制器名称相应地更改它，甚至你的小部件代码不是相应更新它也有'eventSources' => ['/schedule/filter-events'],它应该是'eventSources' => ['/event/filter-events'],。

所以这次只需复制粘贴下面的整个视图代码，不要改变任何东西。因为你必须把它标记为正确，我不会再用勺子喂你了，虽然这是正确的答案，应该被授予赏金。

在集成代码时，解决和修复语法错误是您需要解决的问题。提供的解决方案是有效的，你没有集成它并不意味着它不是正确的答案。
