Codeigniter日历没有显示正确的数据和设置限制不起作用

Mr.*_* ED 8 php codeigniter

我正在使用CodeIgniter 日历库.

我有两个表,我从我的数据库中获取日历数据.

  1. 事件表
  2. extra_events表

问题我有2个foreach循环与第二个foreach循环$query2->result_array()它不让我从数据库表中获取每天的第一个事件extra_events我也试图能够设置额外事件表的限制但不工作.

从extra_events表中

例

Test 2 | Example 2
       | Example 3
Run Code Online (Sandbox Code Playgroud)

它应该产生 

Test 1 | Example 1 <!-- Missing
Test 2 | Example 2
       | Example 3
Run Code Online (Sandbox Code Playgroud)

问我怎样才能确保为$ query2-> result_array()得到所有正确的结果.

现在解决了

我不得不创建两个表,然后在模型函数中添加了这一行

$calendar[$event['day']] = '<br/>' . $event['event'];

下面是主事件的第一个foreach,然后是任何其他额外事件,使用存在数组键的第二个foreach.

现在,这也让我可以控制在foreach循环中的额外事件中显示的行数.

public function get_calendar_events($year, $month) {
        $calendar = array();

        $events = $this->get_events($year, $month);

        foreach($events as $event) {

            // Added line for main calendar event
            $calendar[$event['day']] = '<br/>' . $event['event'];

            // Passes main event id to extra_events get function
            $extra_events = $this->get_extra_events($event['events_id']);

            // checks if array key exists for extra event in side foreach loop
            foreach($extra_events as $extra_event) {
                if (array_key_exists($extra_event['day'], $calendar)) {
                    $calendar[$extra_event['day']] = $calendar[$extra_event['day']] . '<br/>' .  $extra_event['event'];
                } else {
                    $calendar[$extra_event['day']] =  $extra_event['event'];
                }
            }
        }
