您好,这是我的代码,我想让它动态,请为我提供一个如何做到这一点的解决方案.
$start = strtotime($this->input->post('leave_from'));
$end = strtotime($this->input->post('leave_to'));
$days_between = ceil(abs($end - $start) / 86400 + 1);
if($this->input->post('leave_type') == 3){
$days_between = 0.5;
}
我想让这个动态如何使用查询.
$q = "set leave_applications.days = '0.5' on leave_applications where leave_type = 3 ";
$days_between = $this->leave_application_model->q_single($q);
不知道它是否正确但是它显示错误
Unknown system variable ‘days’ set leave_applications.days = ‘0.5’ on
leave_applications where leave_type = 3
帮帮我怎么做.
谢谢.
最佳答案
UPDATE `leave_applications` SET `days` = '0.5' WHERE `leave_type` = 3
