help for login page in php

I am new in php. I am using mysql database and can save the customer username, password and address through php page.
Now i would like to know that how to display that customer individual data in the php page, means when user login it should display his/her data to be edit. I created one page for login and can login easily but not able to see the users individual information which user can edit...below is the login page code:

<?php
// Connects to your Database
mysql_connect("localhost", "root") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());

//Checks if there is a login cookie
if(isset($_COOKIE['ID_my_site']))

//if there is, it logs you in and directes you to the members page
{
$username = $_COOKIE['ID_my_site'];
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check ))
{
if ($pass != $info['password'])
{
}
else
{
header("Location: members.php");

}
}
}

//if the login form is submitted
if (isset($_POST['submit'])) { // if form has been submitted

// makes sure they filled it in
if(!$_POST['username'] | !$_POST['pass']) {
die('You did not fill in a required field.');
}
// checks it against the database

if (!get_magic_quotes_gpc()) {
$_POST['email'] = addslashes($_POST['email']);
}
$check = mysql_query("SELECT * FROM users WHERE username = '".$_POST['username']."'")or die(mysql_error());

//Gives error if user dosen't exist
$check2 = mysql_num_rows($check);
if ($check2 == 0) {
die('That user does not exist in our database. <a href=registration.php>Click Here to Register</a>');
}
while($info = mysql_fetch_array( $check ))
{
$_POST['pass'] = stripslashes($_POST['pass']);
$info['password'] = stripslashes($info['password']);
$_POST['pass'] = md5($_POST['pass']);

//gives error if the password is wrong
if ($_POST['pass'] != $info['password']) {
die('Incorrect password, please try again.');
}

else
{

// if login is ok then we add a cookie
$_POST['username'] = stripslashes($_POST['username']);
$hour = time() + 3600;
setcookie(ID_my_site, $_POST['username'], $hour);
setcookie(Key_my_site, $_POST['pass'], $hour);

//then redirect them to the members area
header("Location: members.php");
}
}
}
else
{

// if they are not logged in
?>
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
<table border="0">
<tr><td colspan=2><h1>Login</h1></td></tr>
<tr><td>Username:</td><td>
<input type="text" name="username" maxlength="40">
</td></tr>
<tr><td>Password:</td><td>
<input type="password" name="pass" maxlength="50">
</td></tr>
<tr><td colspan="2" align="right">
<input type="submit" name="submit" value="Login">
</td></tr>
</table>
</form>
<?php
}

?>
Many thanks

what do you mean? I'm not sure...

----
{ if cookie is set}
$uid=mysql_real_escape_string($HTTP_COOKIE_VARS['cookie1']);

$getdetails=mysql_query("SELECT * FROM table WHERE username='$uid'");
$detailsarray=mysql_fetch_array($getdetails);

$detailname1=$detailsarray['detailname1'];
$detailname2=$detailsarray['detailname2'];
$detailname3=$detailsarray['detailname3'];


echo"$detailname1 $detailname2 $detailname3";

{else die or whatever}

quite new to it myself so..

 

I think you are able to do it using frameworks like zend
