here is my code (html)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

<html>
<head>
<script type开发者_JAVA百科="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#login_form").submit(function() {
var uname = $("#username").val();
var upass = $("#password").val();
$.post("auth.php", { username: uname, password: upass}, function(data) {
$("#errorshow").html(data);
});
return false;
});
});
</script>
</head>
<body>
<form id="login_form" method="post">
<p>Username: <input type="text" id="username" /></p>
<p>Password: <input type="password" id="password" /></p>
<p><input type="submit" value="Login" /></p>
</form>
<div id="errorshow"></div>
</body>
</html>
here is the php (auth.php)
<?php
mysql_connect("","","") or die(mysql_error());
mysql_select_db("") or die(mysql_error());
$username = $_POST['username'];
$password = $_POST['password'];
$query = mysql_query("select username,password,active,role from tbl_logins where username = '$username'") or die(mysql_error());
while($row = mysql_fetch_assoc($query)) {
// CHECK FOR EMPTY FIELDS
if(empty($username) || empty($password)) {
print "the username or password is empty";
}
//CHECK FOR USERNAME EXISTANCE
elseif($db->num_rows($query) == 0) {
print "the username you entered doesnt exist";
}
//CHECK FOR PASSWORD IS CORRECT
elseif(sha1($password) != $row['password']) {
print "the password you entered is incorrect";
}
//CHECK IF ACCOUNT IS ACTIVE
elseif($row['active'] == 'no') {
print "your account is not active. please verify your email";
}
else {
//create cookie and login user.
$_SESSION['AUTHID'] = sha1($row['hash']);
//routh to appropriate role section
if($row['role'] == "0") {
$_SESSION['error'] = "";
header("Location: /_admin/dashboard.php");
} else {
$_SESSION['error'] = "";
header("Location: /worldex/_members/index.php");
}
}//end else
} //end while
?>
Try changing the line:
$(function() {
to
$(document).ready(function() {
As your script is trying to bind the 'submit' method to a form that doesn't exist (until the page has loaded)
