Hi vijukumar,

You should make it so that the login form posts to the same page as with the login form $_SERVER;

Upon successful login you should have it show a link for the user to click and look at the resume.

Upon successful login:

//code to check login

$login = 1;

if($login == 1 && isset($_SESSION['username']) { // user logged in
 $username = $_SESSION['username'];

$sql = "SELECT user_id FROM `users` WHERE user_name='$username'";
$result = mysql_query($sql) or die("Error in Sql: ".mysql_error());

$row = mysql_fetch_array($result);
$count = mysql_num_rows($result);

$uid = $row['user_id'];

if($count == 1) {

echo "<a href='resume_page.php?uid=$uid' target='_self'>View Resume</a>";

} else {

}
}

On the resume page you'll use GET like this:

if(isset($_GET['uid']) && is_numeric($_GET['uid']) { //is_numeric stops people changing it to text or an array, which might cause problems.

$uid = htmlspecialchars($_GET['uid']); // again more protection, better to be safe than sorry.

$sql = "SELECT * FROM post_my_resume WHERE user_id='$uid'";
$result = mysql_query($sql) or die("Error in SQL: ".mysql_error());
$row = mysql_fetch_array($result);

//user $row['field'] now to format your page as you want it.

} else {
//if uid is not set, or if it is not numeric. Show them an error message.
}

Hope that helps,

Sam
