我有一个具有这种结构的用户表:
ID
用户名
密码
经销商(管理员)
现在我想检查登录,如果用户是经销商,经销商可以保持值0(普通用户)或1(管理员),但我不知道如何做到这一点(我是新手PHP)。
这是登录表单:
<form action="index.php?action=login" method="post" style="width: 50%;">
<input type="hidden" name="login" value="true" />
<?php if ( isset( $results['errorMessage'] ) ) { ?>
<div class="errorMessage"><?php echo $results['errorMessage'] ?></div>
<?php } ?>
<ul>
<li>
<label for="username">Username</label>
<input type="text" name="username" id="username" placeholder="Uw gebruikersnaam" required autofocus maxlength="20" />
</li>
<li>
<label for="password">Password</label>
<input type="password" name="password" id="password" placeholder="Uw wachtwoord" required maxlength="20" />
</li>
</ul>
<div class="buttons">
<input type="submit" name="login" value="Login" />
</div>
</form>
这是登录功能:
function login() {
$results = array();
$results['pageTitle'] = "Admin Login | Gemeente Urk";
$host = "localhost";
$mysqluser = "root";
$mysqlpass = "usbw";
$db = "wagenpark";
mysql_connect($host, $mysqluser, $mysqlpass);
mysql_select_db($db);
if ( isset( $_POST['login'] ) ) {
$gebruiker = $_POST['username'];
$wachtwoord = $_POST['password'];
$sql = "SELECT * FROM users WHERE username='".$gebruiker."' AND password='".$wachtwoord."' LIMIT 1";
$res = mysql_query($sql) or die (mysql_error());
if (mysql_num_rows($res) == 1) {
$_SESSION['username'] = $gebruiker;
header( "Location: index.php" );
} else {
// Login failed: display an error message to the user
$results['errorMessage'] = "Incorrect username or password. Please try again.";
require( TEMPLATE_PATH . "/admin/loginForm.php" );
}
} else {
// User has not posted the login form yet: display the form
require( TEMPLATE_PATH . "/admin/loginForm.php" );
}
}
谢谢。
答案 0 :(得分:1)
如果我理解正确,你有一个MySQL数据库,你可以在其中保存用户名,身份证,密码以及他/她是否为管理员。在这部分:
$res = mysql_query($sql) or die (mysql_error());
if (mysql_num_rows($res) == 1) {
$_SESSION['username'] = $gebruiker;
header( "Location: index.php" );
您可以获取结果的Admin值。它可能看起来像这样:
$res = mysql_query($sql) or die (mysql_error());
if (mysql_num_rows($res) == 1) {
$_SESSION['username'] = $gebruiker;
while($row = mysql_fetch_object($res))
{
$admin = $row->Admin;
}
if ($admin == 1) {Do something...}
else {Do something if he is not Admin}
header( "Location: index.php" );
然后你可以将它保存到$ _SESSION。
我跳了帮助,如果它不起作用,请告诉我。
