我有日历，其日期已预订并保存在数据库中。我正在尝试从数据库中提取预订并在相应的日期下显示。一切都工作正常，除了事情，我希望日期只是文本而不是链接，当该日期有超过 5 个事件时。
我知道日历模板没有内容单元格和内容单元格。但是我希望日期在附加超过 5 个事件时没有链接。
我的模型：
public function bookingcalender($year=null,$month=null)
{
if(!$year)
{
$y = date('Y');
}
else
{
$y = $year;
}
if(!$month)
{
$m = date('m');
}
else
{
$m = $month;
}
$this->config = array(
'show_next_prev' => TRUE,
'next_prev_url' => 'http://joshuaflinn.com/CI/booking/show',

您拥有的选项是有限的，因为 Codeigniters 日历库在模板中只有两个伪变量cal_cell_no_content和cal_cell_content，可以根据您想要显示的内容进行播放。
快速查看门后会发现库使用 isset() 来确定使用两个伪变量中的哪一个。它调用str_replace {content} {day}，为一个有点黑客的解决方案打开了大门：
public function bookingcalender($year=null,$month=null)
{
if(!$year)
{
$y = date('Y');
}
else
{
$y = $year;
}
if(!$month)
{
$m = date('m');
}
else
{
$m = $month;
}
$this->config = array(
'show_next_prev' => TRUE,
'next_prev_url' => 'http://joshuaflinn.com/CI/booking/show',
'template' => '{table_open}<table class="availability-calendar">{/table_open}
{heading_row_start}<tr class="toolbar">{/heading_row_start}
{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
{heading_previous_cell}<th><a href="{previous_url}"><</a></th>{/heading_previous_cell}
{heading_next_cell}<th><a href="{next_url}">></a></th>{/heading_next_cell}

);
$this->load->library('calendar',$this->config);
$conf_data = $this->get_booked_dates($year,$month);
return $this->calendar->generate($year,$month,$conf_data);
}
public function get_booked_dates($year,$month)
{
$query = $this->db->select('client_name,booking_date')->from('bookings')->like('booking_date',"$year-$month")->get();
$cal_data = array();
foreach($query->result() as $row)
{
$dt = explode("-", $row->booking_date);
$k = intval($dt[2]); // MAKE INTEGER OF DAY NUMBER
if( @$cal_data[$k] == '' )
{
$cal_data[$k] = $row->client_name;
}
else
{
$cal_data[$k] .= ','.$row->client_name;
}
}
// LOOP THROUGH EACH DAY TO FIND THOSE WITH MORE THAN 5 EVENTS
foreach($cal_data as $key=>$val){
// COUNT THE NUMBER OF COMMAS THAT OCCUR IN STRING
$count = strlen($val) - strlen(str_replace(',','',$val));
if($count > 4){ // IF MORE THAN 4 COMMAS (> 5 EVENTS) THEN NO LINK...
$cal_data[$key] = '{day}<span class="date-data">'.$val.'</span>';
} else { // LINKED DAY
$cal_data[$key] = '<a href="#" data-toggle="collapse" data-target="#bookingform" data="'.$year.'-'.$month.'-{day}">{day}</a><span class="date-data">'.$val.'</span>';
}
}
return $cal_data;
}
注意：我在模板中更改了两行：{cal_cell_content}{content}{/cal_cell_content}和{cal_cell_content_today}<div class="highlight">{content}</div>{/cal_cell_content_today}
您现在只需要设置{content}因为{day}是在内容中指定的，内容也包含从查询返回的 html。
更新：我现在已经测试了解决方案，它似乎工作正常！
如果需要更灵活的解决方案，并且不想在查询返回的内容中混合模板 html，则必须操作或扩展日历库。
