php - Codeigniter 日历不显示正确的数据并且设置限制不起作用

标签 php codeigniter

我正在使用 CodeIgniter Calendar图书馆。

我有两个表，我从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 循环和第二个 foreach 循环 $query2->result_array()它不允许我每天从数据库表 extra_events 中获取第一个事件我也在尝试能够从额外事件表中设置限制但不起作用。

来自extra_events表格

例子

Test 2 | Example 2
       | Example 3

它应该产生

Test 1 | Example 1 <!-- Missing
Test 2 | Example 2
       | Example 3

Question how can I make sure I get all the results correct for $query2->result_array().

获取函数

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

        $this->db->select('*');
        $this->db->from('events');
        $this->db->where('year', $year);
        $this->db->where('month', $month);
        $query1 = $this->db->get();

        foreach ($query1->result_array() as $event) {

            $this->db->select('*');
            $this->db->from('extra_events');
            $this->db->where('events_id', $event['events_id']);
            $this->db->where('year', $year);
            $this->db->where('month', $month);
            //$this->db->limit(2);
            $query2 = $this->db->get();

            foreach ($query2->result_array() as $result) {

                if (array_key_exists($event['day'], $calendar)) {

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

                } else {

                    $calendar[$event['day']] = '<br/><b>From Events Table</b> <i class="fa fa-long-arrow-down"></i><br/>' . $event['event'] . '<hr><b>From Extra Events Table</b> <i class="fa fa-long-arrow-down"></i>' ;

                }

            }
        }

        return $calendar;

    }

最佳答案

已解决

我必须创建两个表，然后在模型函数上添加这一行

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

下面是主要事件的第一个 foreach，然后任何其他额外事件使用第二个 foreach 并存在数组键。

This now also lets me control how many rows are now displayed in extra events foreach loop.

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'];
                }
            }
        }


        return $calendar;
    }
