我正在检查我的mysql数据库中的用户级别,如果匹配则显示链接。
这是我目前的代码:
<?php
$mysqli = new mysqli('host', 'name', 'psw', 'db');
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if ($result = $mysqli->query("SELECT user_level FROM users WHERE user_level = 1 ")) {
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
}
/* until here everything works fine - the code below seems to be not working */
if ($result == $_SESSION['userlevel']) {
$link = 'AdminLayout.php';
printf ('<a href="' .$link. '">Adminpanel </a>');
/* close result set */
$result->close();
}
/* close connection */
$mysqli->close();
?>
printf("Result set has %d rows.\n", $row_cnt);
仅用于检查连接是否正常,并且检测到user_level = 1。
我将$_SESSION['userlevel']
存储在我的登录表单中:
if(isset($_POST['submitted']))
{
session_start();
$mysqli = new mysqli('host', 'name', 'psw', 'db');
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
else ($result = $mysqli->query("SELECT user_level FROM users WHERE user_level = 1 ")) {
if (mysqli_num_rows($result == 1) {
$ulevel = $mysqli_fetch_array($result);
$ulevel = $_SESSION['userlevel'];
}
}
}
?>
不幸的是,我的登录表格不再适用于添加这些行。
有人可以帮助我让它发挥作用吗?如何正确存储登录帐户的用户级别,以便在另一个站点上调用它?
长话短说:我想检查我的MySQL数据库中的用户级别,如果已登录的用户匹配,则显示该链接。

请更正您的代码,如下所示。 登录页面:
operator
和其他代码:
if(isset($_POST['submitted']))
{
session_start();
$mysqli = new mysqli('host', 'name', 'psw', 'db');
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
elseif ($result = $mysqli->query("SELECT user_level FROM users WHERE user_level = 1 ")) {
if (mysqli_num_rows($result) == 1) {
$_SESSION['userlevel'] = $mysqli_fetch_array($result);
}
}
}
?>
