谁能看到与以下问题相关的速记法有什么问题吗?
echo "<td><font size=1 color=#e4d6b5>" . ($row['tier']<$_SESSIONS['tier'] ? "ACCESS DENIED" : $row['contents']) . "</font></td>";
我的数据库中有两个表:
1.)成员(id,用户名,电子邮件,密码,盐,层)
2.)opwire(类别,内容,日期,用户标识,安全级别)
我试图根据其安全级别(引用成员级别与opwire的seclevel)来授予当前登录用户“内容”的访问权限或受限访问这些内容的权限。我也不完全确定自己正在使用http:// www.wikihow.com/Create-a-Secure-Login-Script-in-PHP-and-MySQL
通常,我可以通过以下方式获得当前用户:
$userId = $_SESSION['user_id'];
整个表构建php在下面。当前,具有任何层的用户在应限制其级别时,可能会错误地查看任何seclevel内容。
<?php
include_once 'functions.php';
include_once 'db_connect.php';
sec_session_start();
if(login_check($mysqli) == true) {
$con=mysqli_connect("localhost","mylogin","mypassword","mysqldatabase");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
function getColor($strOption)
{
switch ($strOption)
{
case "Case 1":
return "#cbae80";
case "Case 2":
return "#e59350";
case "Case 3":
return "#b7aaa4";
}
}
$result = mysqli_query($con,"SELECT opwire.*,members.username FROM opwire
LEFT JOIN members on opwire.userid=members.id order by date DESC");
echo "<table border='1'>
<tr>
<th>Category</th>
<th>Contents</th>
<th>Date/Time</th>
<th>Operative</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td><font size=1 color='".getColor($row['category'])."'> " . $row['category'] . "</font></td>";
echo "<td><font size=1 color=#e4d6b5>" . ($row['tier']<$_SESSIONS['tier'] ? "ACCESS DENIED" : $row['contents']) . "</font></td>";
echo "<td><font size=1 color=silver>" . $row['date'] . "</font></td>";
echo "<td><font size=1 color=gold>" . $row['username'] . "</font></td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
} else {
echo 'Access to this area requires security clearance. <br/>';
}
?>
最佳答案
我相信在每种情况下您都需要在结尾处加上“ BREAK”,否则它将一直贯穿到“#b7aaa4”;
function getColor($strOption)
{
switch ($strOption)
{
case "Case 1":
return "#cbae80";
break;
case "Case 2":
return "#e59350";
break;
case "Case 3":
return "#b7aaa4";
break;
}
}
