But please do not use cookies to store a password as code! Cookies are human
readable with some add-ons....
Check like this:
if someone registers, insert it into a table:
<?php
$username = mysql_real_escape_string($_POST["username"]);
$password = md5($_POST["password"]);
mysql_query("INSERT INTO USER VALUES('" . $username . "','" . $password . "')");
header('location: register_success.php');
?>
Then, if someone wants to log in, use like this:
<?php
$username = mysql_real_escape_string($_POST["username"]);
$password = md5($_POST["password"]);
$sel = "SELECT * FROM USER WHERE USERNAME = '" . $username . "' AND PASSWORD =
'" . $password . "'";
$unf = mysql_query($sel);
$count = mysql_num_rows($unf);
if ($count == 1) {
header('location: login_success.php');
}
else {
echo "Login not successful!";
}
?>
If you want to store something into cookies, use a name which is not good
understandable, like a shortcut for a logical sentense:
Titcftmws ("This is the cookie for the main webSite") or something ^^
In there, you can save username and password, but PLEASE save the password at
least md5()-encryptet, so not everyone can save it.
Now you can check like this:
<?php
if ($_COOKIE['Titcftmws'] == mysql_real_escape_string($_POST["username"]) . "|"
. md5($_POST["password"])) {
//in the cookie is for the user with username 'jack' and password 'test'
this value: "jack|098f6bcd4621d373cade4e832627b4f6"
echo "you are logged in";
}
else {
echo "not logged in!";
}
?>
This is as far as I know a quite high level of security, in comparisions with
other ways.
