Hello, I have just recently completed a blog system with PHP. I am now
enhancing it with jQuery, but I have come across some problems.
My login form is in a toggle div, so I submit the form info
asynchronously to the db via jQuery and it's ajax features. However
when I do this the form does everything correctly, and reloads the
page...but for some reasons the sessions do not work, therefore you
are not logged in.
I have also noticed that a javascript reload will work with jQuery but
an html meta refresh will not, does anyone know why this is?
The code for my login form is this...
<?php
echo "<form name='loginsub' method='post' action='db.php'>\n";
echo "Username <input type='text' name='username' id='username'
autocomplete='off' /> \n";
echo "Password <input type='password' name='password'
id='password' autocomplete='off' /> \n";
echo "<input type='submit' value='Login' id='loginsubmit' />\n";
echo "</form>\n";
?>
The code for db.php is this...
<?php
@include('connect.php');
$user = $_POST['username'];
$pass = $_POST['password'];
$pass = md5( $pass );
$passm = sha1( $pass );
$passn = md5( $passm );
$passo = sha1( $passn );
$passp = md5( $passo );
if($user && $pass){
$sql = "SELECT * FROM `users` WHERE `username`='$user'";
$res = mysql_query($sql) or die(mysql_error());
if(mysql_num_rows($res) == 1){
$epass = md5($pass);
$sql2 ="SELECT * FROM `users` WHERE `username`='$user' AND
`password`='$passp'";
$res2 = mysql_query($sql2) or die(mysql_error());
if(mysql_num_rows($res2) == 1){
//successful login
echo "Currently logging you in, $user\n";
$row = mysql_fetch_assoc($res2);
$_SESSION['uid'] = $row['id'];
echo "<script
type='text/javascript'>setTimeout('location.reload
(true)',3000)</script>\n";
//echo "<meta http-equiv='refresh' content='4' />\n";
}else {
echo "<b>Username or password incorrect</b>\n";
}
}else {
echo "<b>Username or password incorrect</b>\n";
}
}else {
echo "<b>All fields need to be filled in</b>\n";
}
?>
Then finally the jQuery for the form is this...
$(function(){
$('#loginsubmit').click(function(){
var username = $('#username').val();
var password = $('#password').val();
$.ajax({
url: 'db.php',
type: 'POST',
data: 'username=' + username + '&password=' + password,
success: function(result) {
$('#response').remove();
$('#navloginf').fadeOut("slow");
$('#nave').slideDown("fast");
$('#nave').append('<p id="response">' + result + '</
p>');
}
});
return false;
});
});
If anyone could help me out on why the sessions are not work, that
would be very nice.
