我正在使用CodeIgniter Calendar庫。Codeigniter日曆不顯示正確的數據和設置限制不起作用

我有兩個表，我從我的數據庫中獲取日曆數據。

事件表
extra_events表

我有2的foreach與第二foreach循環$query2->result_array()環路的問題不會讓我從數據庫表extra_events我在每一天的第一事件也試圖能夠從額外的事件表中設置限制，但無法工作。

從extra_events表

例

Test 2 | Example 2 
     | Example 3

應該產生

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

問題我怎麼能保證我得到的所有結果正確的$ query2- > result_array（）。

Get函數

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; 

    }

只是限制get_events您的foreach（）函數中。您可以通過使用迭代變量來限制foreach，如$ i = 0;並運行foreach而$ i <1; 我希望它能爲你工作。 –

@AliShan你可以用我的代碼顯示它。 – user4419336

@ wolfgang1983嘿，你可以用你所期望的更清楚一點。以及添加'print_r（$ query-> result_array（））'結果 –

現在解決

我不得不創建兩個表，然後在模型函數中添加此行

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

低於第一的foreach的主要事件，然後任何其他額外的事件使用數組鍵存在的第二個foreach。

這現在還可以讓我控制多少行現在顯示在額外的事件foreach循環中。

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; 
    }

您可以限制foreach只得到2個事件。

限制get_events（）函數中的foreach循環。

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

     $this->db->where('year', $year); 
     $this->db->where('month', $month);

     $results = $query->result_array(); 

     $i = 0; 
     foreach ($results as $event) { 
      if ($i < 2) {  // getting/fetching/extracting value from foreach for 2 times only 
       if (array_key_exists($event['day'], $calendar)) { 

        $calendar[$event['day']] = $calendar[$event['day']] . '

不起作用，出於某種原因現在只能顯示整個日曆的2個結果。在26日的形象日曆上有3它應該顯示2 – user4419336
