if(isset($_POST['btnsave']))
{
    $event =   trim($_POST['event']);
    $other_event = trim($_POST['other_event']);
    $date = date("Y-m-d", strtotime($_POST['date']));
    $info = trim($_POST['notes']);
    $upd_date = date('Y-m-d H:i:s');//upl_date
    $ucode = md5(uniqid(rand()));
     if(empty($event) || ($other_event =='others' && empty($other_event)))
     {
         $errMSG = "Please enter camera name";
     }
     else
     {
        $event_name =  ($event =='others') ?  $other_event : $event;

Answer 1

您缺少value="others"收音机的name="event"。和

if(empty($event) || ($other_event =='others' && empty($other_event)))

应该是

if(empty($event) || ($event =='others' && empty($other_event)))
