我正在我的网站上工作，我有一个基本的表来显示已经注册的人的成员。但是，我不想在表上显示管理员帐户。有没有办法从表中排除用户名/id？在这种情况下，是管理员？提前感谢Josh
这是我的成员列表表代码：
<?php
include("include/session.php");
/**
* displayUsers - Displays the users database table in
* a nicely formatted html table.
*/
function displayUsers(){
$levels = array('1'=>'Member','2'=>'Supporter','3'=>'Donor','4'=>'VIP','5'=>'Veteran','7'=>'Co-Founder','8'=>'Founder','9'=>'Admin');
//do_query
//loop results
$ulevel = mysql_result($result,$i,"userlevel"); $ulevel = $levels[$ulevel];
//continue loop
global $database;
$q = "SELECT username,userlevel,email,timestamp "
."FROM ".TBL_USERS." ORDER BY userlevel DESC,username";
$result = $database->query($q);
/* Error occurred, return given name by default */
$num_rows = mysql_numrows($result);
if(!$result || ($num_rows < 0)){
echo "Error displaying info";
return;
}
if($num_rows == 0){
echo "Database table empty";
return;
}
/* Display table contents */
echo "<table align='"left'" border='"1'" cellspacing='"0'" cellpadding='"3'">'n";
echo "<tr><td><b>Username</b></td><td><b>Level</b></td><td><b>Last Active</b></td></tr>'n";
for($i=0; $i<$num_rows; $i++){
$uname = mysql_result($result,$i,"username");
$ulevel = $levels[mysql_result($result,$i,"userlevel")];
$time = mysql_result($result,$i,"timestamp");
echo "<tr><td>$uname</td><td>$ulevel</td><td>$time</td></tr>'n";
}
echo "</table><br>'n";
}
?>
只需更新您的查询：
$q = "SELECT username,userlevel,email,timestamp "
."FROM ".TBL_USERS." where userlevel<>'Admin' ORDER BY userlevel DESC,username";
如果您使用PDO库：
...
$adminLevel = 'Admin';
$q = "SELECT username,userlevel,email,timestamp "
."FROM ".TBL_USERS." where userlevel <> ? ORDER BY userlevel DESC,username";
$statement = $database->prepare($q);
$result = $statement->execute(array($adminLevel));
... // Go on with the rest of your code
您可以相应地修改它。。
SELECT * FROM table WHERE level <> 'admin'
