我有一个具有两级访问权限的网站,管理员和客户.创建新帐户时,我希望管理员看到制作其他管理员或客户的选项.我希望客户只看到客户选项.我正在使用 PHP.这是我尝试过的： @H_777_5@

<?PHP
 foreach ($tyPEs as $type) {
    if (!isset($_SESSION['user_id'])) { //Anyone on the web can see
        echo "<option value=\"" . $type['Customer'] . "\">". $type['Customer'] . "</option>\n";
    }
    else 
    {
        if ($is_admin) { //Only admin can see this option
            echo "<option value=\"" . $type['user_type_id']. "\">" . $type['type_name'] . "</option>\n";
        }

    //Only customer can see
        echo "<option value=\"" . $type['Customer']. "\">" . $type['Customer'] ." </option>\n";
    }
}
?>

它没有完成我的意图.如果有人建议我可以尝试,那将是伟大的.如果您希望我的其他任何代码更好地理解逻辑,请告诉我.

<?PHP
 foreach ($types as $type) {
    if (!isset($_SESSION['user_id'])) { //Anyone on the web can see
        echo "<option value=\"" . $type['Customer'] . "\">". $type['Customer'] . "</option>\n";
    }
    else 
    {
        if ($is_admin) { //Only admin can see this option
            echo "<option value=\"" . $type['user_type_id']. "\">" . $type['type_name'] . "</option>\n";
        } else { // <-- here

    //Only customer can see
        echo "<option value=\"" . $type['Customer']. "\">" . $type['Customer'] ." </option>\n";
       }
    }
}
?>
