Php mysql if/else速记

有人能看出与下面的问题相关的速记有什么问题吗

echo "<td><font size=1 color=#e4d6b5>" . ($row['tier']<$_SESSIONS['tier'] ? "ACCESS DENIED" : $row['contents']) . "</font></td>";

下面是整个表构建php。当前，任何层的用户都可能错误地查看任何seclevel内容，而他们的层应该对其进行限制

<?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/>';
}

?>

我相信每个案例的结尾都需要“BREAK”，否则它会一直掉到“#b7aaa4”

那么到底是什么不起作用呢？第一个出现的问题是什么？粗略地看一看，这里有一大堆错误，所以一次从一个问题开始。（$row['tier']当tier 2的用户登录时，他们会看到表中与“内容”相关的所有内容。他们应该只看到设置为seclevel 2或更低级别的每一个内容行。我使用开关的
