$ _SESSION [＆＃39;变量＆＃39;]不会被取消或更改

Question

$UserType = $row['UserType'];

$_SESSION['UserID'] = $row['UserID'];

//unset($_SESSION['UserType']);
$_SESSION['UserType'] = $UserType;
//unset($_SESSION['Dashboard']);
if ($UserType == 'read' OR 'edit' OR 'admin') {$_SESSION['Dashboard'] = 'YES';} 
else {$_SESSION['Dashboard']='NO';}

if ($_SESSION['Dashboard'] == 'YES') { ..... }

其他没有达到..为什么请？显然我也更喜欢TRUE或FALSE

Answer 1

更改此行

if ($UserType == 'read' OR 'edit' OR 'admin') {$_SESSION['Dashboard'] = 'YES';} 

到

if ($UserType == 'read' OR $UserType =='edit' OR $UserType =='admin') {$_SESSION['Dashboard'] = 'YES';} 

Answer 2

您的if语句不正确。目前的代码基本上是比较$ UserType ==＆＃39; ready＆＃39;或者编辑＆＃39;不是空的＆＃39;，或者管理员不是空的

你想：

if（$ UserType ==＆＃39; read＆＃39; OR $ UserType ==＆＃39; edit＆＃39; OR $ UserType ==＆＃39; admin＆＃39;）

Answer 3

运行您的支票

if ( ($UserType == 'read') OR ($UserType =='edit') OR ($UserType =='admin') ) {
$_SESSION['Dashboard'] = 'YES';
}else { 
$_SESSION['Dashboard']='NO';
}
