HTML
<form method="post" class="login"> <p id="login-error"></p>
<p>
<label for="login">Username:</label>
<input type="text" name="login" id="login" placeholder="username">
</p>
<p>
<label for="password">Password:</label>
<input type="password" name="password" id="password" placeholder="password">

<p class="login-submit">

</p>
<p class="forgot-password">Fill your username and password.</p> </form>
它什么也没显示!怎么了?有什么解决办法吗?id 名称是正确的
编辑:我还有另一个问题。不想为此提出另一个问题。我正在尝试从 validate.php 中获取 ajax 答案(它位于 /views/admin/validate.php - 它在打开 domain.com/validate 时运行)
$(document).ready(function() {
$('.login-button').click(function() {
var login = $("#login").val();
var password = $('#password').val();
$.ajax({
type: 'POST',
url: '/view/admin/validate.php',
data: {
login : login,
password : password
},
success: function(data){
$('#login-error').html(data);
}
});
});
});
验证.php
<?php
session_start();
$user = mysql_real_escape_string($_POST['login']);
$password = mysql_real_escape_string(sha1($_POST['password']));
$query = mysql_query("SELECT * FROM `users` WHERE name = '$user' AND pass = '$password' AND privileges = 'superuser'");
$num_rows = mysql_num_rows($query);
if($num_rows == '0') {
echo "Username and Password are incorrect! (Maybe you don't have permission!)";
}
elseif($num_rows == '1') {
$expire = time()*60*60*60*60;
setcookie("user","$user",$expire);
$_SESSION['user'] = $user;
include '/views/admin/admin.php';
}
?>
它应该返回用户名和密码不正确!(也许你没有权限!) - 但它没有..任何解决方案?
