我正在实施登录功能。
javascript部分:
function login() {
var n = $('#userl').val();
var p = $('#passl').val();
if ( n != "" && p != ""){
$.post("functions.php",{userl: n, passl: p}).done(function(mesaj){
if(mesaj == "")
alert("!!!!!!!!!!EMPTY STRING!!!!!");
else
alert(mesaj);
});
}
else {
alert("Enter name and/or passwort");
}
};
来自function.php的函数看起来是:
function login($nume,$parola)
{
$sql = "SELECT id FROM `Users` WHERE nume ='".$nume."' ANY password = '".md5($parola)."'";
$q = mysql_query($sql);
if(!$q)
die(json_encode(array("mesaj" => "Invalid")));
else{
$x = mysql_fetch_array($q);
if (empty($x))
die(json_encode(array('mesaj' => 'The user does not exist')));
else {
// $user = new User($x['id']);
session_start();
$_SESSION['user_id'] = $x['id'];
$_SESSION['loggedin'] = "yes";
die(json_encode(array("mesaj"=>"you were logged")));
}
}
//this part may be useless
die(json_encode(array("mesaj"=>"you were not logged")));
}
if (isset($_POST['nume']) AND isset($_POST['parola']))
login($_POST['nume'], $_POST['parola']);
问题是它一直警告EMPTY STRING,我认为它甚至没有从php访问我的登录功能......所以消息以它的方式返回:空
答案 0 :(得分:3)
$.post("functions.php",{userl: n, passl: p})
将其与
进行比较if (isset($_POST['nume']) AND isset($_POST['parola']))
发现你的错误:)
您正在发送user1
和pass1
,而在PHP中,您正在检查显然不存在的nume
和parola
。 < / p>
