Codeigniter日历如何每天获得多个事件
我目前正在开发codeIgniter 3日历库，我可以在每个月的每一天向数据库添加新的信息行
如果一天有2行插入，我应该能够看到当天的两个日历事件。
2015-12-25必须如图所示行。
我希望能够展示而不仅仅展示一个活动，而是展示当天的活动。
问题：我如何让get_calendar_data函数能够获取日历当天的行。目前在2015-12-25它只显示一行。
获取数据功能
public function get_calendar_data($year, $month) {
$cell_data = array();
$query = $this->db->get('calendar');
if ($query->num_rows() > 0) {
$row = $query->row();
$this->db->select('*');
$this->db->from('calendar');
$this->db->where('year', $year);
$this->db->where('month', $month);
$this->db->where('day', $row->day);
$query = $this->db->get();
foreach ($query->result() as $result) {
$cell_data[$result->day] = $result->data;

return $cell_data;

解决！
经过很长一段时间搜索网页并尝试新事物后，我发现下面的代码函数 array_key_exists 让我每天都能获得多个事件。
public function get_events($year, $month) {
$calendar = array();
$this->db->where('year', $year);
$this->db->where('month', $month);
$query = $this->db->get('calendar');
$results = $query->result_array();
foreach ($results as $event) {
if (array_key_exists($event['day'], $calendar)) {
$calendar[$event['day']] = $calendar[$event['day']] .'<ul class="list-unstyled"><li>'. anchor(base_url() .'report/events/'. $year .'/'. $month .'/'. $event['calendar_id'], $event['data']) . '</li></ul>';
} else {
$calendar[$event['day']] = '<ul class="list-unstyled"><li>' . anchor(base_url() .'report/events/'. $year .'/'. $month .'/'. $event['calendar_id'], $event['data']) . '</li></ul>';
}
}
return $calendar;
}

答案 1 :(得分：0)
这是一个很好的答案，我试图修改 codeigniter 日历制作 MY_calendar ，但这要好得多。 我仍然没有添加事件的链接。
public function get_datos_calendario($year, $month)
{
$this->db->like('fecha', "$year-$month", 'after');
$query = $this->db->get('tareas');
$datos_calendario = array();
$results = $query->result_array();
foreach ($results as $event) {
$day = ltrim(substr($event['fecha'], 8, 2), '0');
if (array_key_exists( $day, $datos_calendario ) ) {
$datos_calendario[$day] = $datos_calendario[$day] .'<ul class="list-unstyled"><li>'. $event["descripcion"] . '</li></ul>';
} else {
$datos_calendario[$day] = '<ul class="list-unstyled"><li>' . $event["descripcion"] . '</li></ul>';
}
}
