CodeIgniter的日曆沒有顯示某些條目從數據庫表

Question

我用笨的日曆庫從數據庫表中填充數據，但顯然它有以下問題：

• 不超過1個reocrd顯示
• 項低於當月9日當其他所有工作都不顯示時

爲什麼會發生這種情況？

型號：

class reminders_model extends CI_Model { 

var $conf; 

function reminders_model() { 
    parent::__construct(); 
    $this->conf = array(
     'start_day' => 'monday', 
     'month_type' => 'long', 
     'day_type' => 'long' 
     ); 
    $this->conf['template'] = ' 
     {table_open} 
      <table class="calendar"> 
     {/table_open} 

     {week_day_cell} 
      <th class="day_header">{week_day}</th> 
     {/week_day_cell} 

     {cal_row_start}<tr class="days">{/cal_row_start} 
     {cal_cell_start}<td class="day">{/cal_cell_start} 

     {cal_cell_content} 
      <span class="day_listing">{day}</span>&nbsp;&bull; {content}&nbsp;{/cal_cell_content} 
     {cal_cell_content_today} 
      <div class="today"><span class="day_listing">{day}</span>&bull; {content}</div>{/cal_cell_content_today} 
     {cal_cell_no_content} 
      <span class="day_listing">{day}</span>&nbsp;{/cal_cell_no_content} 
     {cal_cell_no_content_today} 
      <div class="today"><span class="day_listing">{day}</span></div>{/cal_cell_no_content_today} 
     '; 
} 

function get_calendar_data($year, $month) { 
    $query = $this->db->select('date, reason')->from('reminders')->like('date', "$year-$month", 'after')->get(); 

    $cal_data = array(); 

    foreach ($query->result() as $row) { 
     $cal_data[substr($row->date, 8, 2)] = $row->reason; 
    } 

    return $cal_data; 
} 

function generate($year, $month) {  
    $this->load->library('calendar', $this->conf); 

    $cal_data = $this->get_calendar_data($year, $month); 

    return $this->calendar->generate($year, $month, $cal_data); 

} 

控制器：

<?php 

class reminders extends CI_Controller { 

function index($year = null, $month = null) { 

    if (!$year) { 
     $year = date('Y'); 
    } 
    if (!$month) { 
     $month = date('m'); 
    } 

    $this->load->model('/summary/reminders_model'); 

    if ($day = $this->input->post('day')) { 
     $this->reminders_model->add_calendar_data(
      "$year-$month-$day", 
      $this->input->post('reason') 
      ); 
    } 

    $data['calendar'] = $this->reminders_model->generate($year, $month); 
    $this->load->view('summary/reminders_view', $data); 
} 

查看：

<?php echo $calendar; ?>

爲了把多個項目進入了一天，說15日你將有創建一個多維數組以獲取多個約會。例如。

function get_calendar_data($year, $month) { 
    $query = $this->db->select('date, reason')->from('reminders')->like('date', "$year-$month", 'after')->get(); 

    $cal_data = array(); 

    foreach ($query->result() as $row) { 
     $day = date('j',$row->date); 
     $cal_data[$day][] = $row->reason; 
    } 

    return $cal_data; 
} 

至於你只得到9的原因，我猜它與你的SUBSTR做（）
