我想用脚本/ AJAX我的登录系统。到目前为止,我已经能够取回阵列的所有错误,如果登录成功后设置$ _SESSION ['身份证']:
I want to use script/ajax for my login system. So far I've been able to get back the array with all the errors and, if log in is successful set the $_SESSION['id']:
<script type="text/javascript">
$(document).ready(function() {
$("input[type=button]").click(function () {
var username = $('input[id=username]').val(); // get the username
var password = $('input[id=password]').val(); // and the password
if (username != '' || password !='') { // if not empty
$.ajax({
type: "POST",
url: "loginUser.php",
data : "username="+username+"&password="+password,
dataType: "json",
success: function (data) {
var success = data['success'];
if(success == 'false'){
var error = data['message'];
alert(error); // the array with all the errors
}else{
$('#mask , .login-popup').fadeOut(300 , function() {
$('#mask').remove();
});// end fadeOut function()
setTimeout("location.href = 'home.php';",1500);
}
}
});//end success function
} else {
alert('Enter some text ! '); // just in case somebody to click witout writing anything :)
}
});//end click function
});//end ready function
</script>
loginUser.php基本检查所有的功能,然后发回的数据是这样的:
loginUser.php basically check all the function and then send back the data like this:
if (empty($_POST)===false){
$email = sanitize($_POST['username']);
$password = sanitize($_POST['password']);
if (empty($email) === true || empty ($password) === true){
$errors[] = 'You need to enter a username and password';
} else if (mail_exists($email) === false){
$errors[] = 'we can\'t find that username. have you registered?';
}else if (user_active($email) === false){
$errors[] = 'you haven\'t activated your account!';
}else {
$login = login($email, $password);
if ($login === false){
$errors[] = 'username/password combination is incorrect!';
}else {
//set user session
$_SESSION['id'] = $login;
//redirect user to home
echo json_encode(array("success"=>'true'
));
}
}
echo json_encode(array("success"=>'false',
"message"=>$errors,
));
}
正如我所说的,我让所有的警报,如果用户名和密码不正确,我也得到了$ _SESSION设置,如果用户名和密码是正确的,但在弹出的保持显示和我没有得到重定向(但我可以,因为访问该会议确定的)。它是正确的测试,如果成功==真或假的== ???
as I said, I get ALL the alert if password and username are not correct and I get the $_SESSION set if password and username are correct but the popup stays shown and I don't get redirect (but I can access because of the SESSION set). Is it correct to test if success is == true or == false???
*的 * 的*编辑:固定的,问题是在PHP文件。看看我的答案......
*** fixed, the problem was in the php file. look at my answer....
固定!问题是在PHP文件中的if else逻辑:
fixed! the problem was in the if else logic in the php file:
