    retrieve data from database

    i want to retrieve data only from a single person after he/she login into the system..here is the code for the retrieving page:

    <title>RETRIEVING</title>
    <?php
    // Connects to your Database
    $host="127.0.0.1"; // Host name
    $username="root"; // Mysql username
    $password=""; // Mysql password
    $db_name="OFCCC"; // Database name
    $tbl_name="register"; // Table name


    // Connect to server and select databse.
    mysql_connect("$host", "$username", "$password")or die("cannot connect");
    mysql_select_db("$db_name")or die("cannot select DB");


    $data = mysql_query("SELECT * FROM register WHERE u_name= 'username'")
    or die(mysql_error());
    Print "<center><table border cellpadding=5>";
    while($info = mysql_fetch_array( $data ))
    {
    Print "<tr>";
    Print "<th>Full Name:</th> <td>".$info['f_Name'] ." " .$info['l_Name']."</td> ";
    Print "<th>IC Number:</th> <td>".$info['ic_Num'] . " </td></tr>";
    Print "<th>Car Plat Number:</th> <td>".$info['plat'] . "</td> ";
    Print "<th>Car Type:</th> <td>".$info['type'] . " </td></tr>";
    Print "<th>Car CC:</th> <td>".$info['cc'] . " </td></tr>";
    Print "<th>Car Transmission:</th> <td>".$info['trans'] . " </td></tr>";
    }
    Print "</table>";
    ?>

    -->u_name : my title of the all of the username in the database
    -->username : the name of textbox in mt login page

    my prob here is what must i call from the registration page(the BOLD) so that the data that will come out only from the person who login to the system..tq

    If username is the name of textbox in mt login page, try
    PHP Code:
    // ...
    $username $_POST['username'];
    $data mysql_query("SELECT * FROM register WHERE u_name='$username'")
    or die(
    mysql_error()); 
    // ...

    hye..i dont know what is wrong,but it still get to error
    lets say i have this in my login.php form:
    <input name="login" type="text" class="textfield" id="login" />
    <input name="password" type="password" class="textfield" id="password"/>

    and this is in my register.php form:
    <form name="register" action="registerExec.php" method="post" >
    Username <input name="uname" type="text" />
    Password<input name="pswd1" type="password" /> <input type="submit" value="Register"/>
    </form>
    and also to insert the data from this page:
    $sql="INSERT INTO register (u_name, p_swd)
    VALUES('$_POST[uname]','$_POST[pswd1]')";

    now, i am success to register and login to the system. so, i think for the retrieve code, i will be like this rite:
    <?php
    // Connects to your Database
    $host="127.0.0.1"; // Host name
    $username="root"; // Mysql username
    $password=""; // Mysql password
    $db_name="retrieve"; // Database name
    $tbl_name="register"; // Table name


    // Connect to server and select databse.
    mysql_connect("$host", "$username", "$password")or die("cannot connect");
    mysql_select_db("$db_name")or die("cannot select DB");

    $user = $_POST['login'];
    $data = mysql_query("SELECT * FROM register WHERE u_name='user'")
    or die(mysql_error());

    while($info = mysql_fetch_array( $data ))
    {
    Print "<tr>";
    Print "<th>WELCOME:</th> <td>".$info['u_name'] ." </td></tr>";
    Print "<th>YOUR PASSWORD:</th> <td>".$info['p_swd'] ." </td></tr>";
    }

    ?>

    TQ =)

    The variable $user must have the $ sign in the sql query too:
    PHP Code:
    $data mysql_query("SELECT * FROM register WHERE u_name='$user'"
