[問題] 有關cookie的問題
有關COOKIE的問題要懇請幫忙..
就是我有一個A網站：http://meeter1.ath.cx/selectmbrs.php
當我點選「人」時他會回傳值到上方的textarea
但是當我換部門點選時時，之前上方所選取的人都會不見..
請問是不是要用cookie來解決？
如果是該如何做呢？
這是A網站的CODE：
<?php
require './unempty.php';
require './config.php';
cnnt2db();
$dept = $_GET['dept'];
if(strlen($dept)==0){
$dept = $_SESSION['ssndepartment'];
}
//往上找嫡系部門ID,Name
function showupdept($dept){
cnnt2db();
$sql = "select `GroupName` from `Group` where `GroupNo` = '$dept'";
$result=mysql_query($sql);
$row=mysql_fetch_row($result);
$alldept[0] = $dept;
$alldept[1] = $row[0];
$pdept = dep_p($dept);
$i = 2;
while($pdept != "root"){
$sql = "select `GroupName` from `Group` where `GroupNo` = '$pdept'";
$result=mysql_query($sql);
$row=mysql_fetch_row($result);
$alldept[$i++] = $pdept;
$alldept[$i++] = $row[0];
$pdept = dep_p($pdept);
}
mysql_close();
return $alldept;
}
//找子部門ID,Name
function showdowndept($dept){
$cdep = explode(",", dep_c($dept));
cnnt2db();
$j = 0;
for ($i=0; $i<sizeof($cdep) ;$i++){
$sql = "select `GroupName` from `Group` where `GroupNo` = '$cdep[$i]'";
$result=mysql_query($sql);
$row=mysql_fetch_row($result);
$alldept[$j++] = $cdep[$i];
$alldept[$j++] = $row[0];
}
mysql_close();
return $alldept;
}
//找部門內員工ID,Name
function showdeptmembers($dept){
cnnt2db();
$sql = "select `UserNO`,`UserName` from `Users` where `Department` =
'$dept'";
$result=mysql_query($sql);
$i=0;
while($row = mysql_fetch_row($result)){
$members[$i++]=$row[0];
$members[$i++]=$row[1];
}
mysql_close();
return $members;
}
?>
