Use some javascript?

// Make sure input as an ID
// e.g. <input type="text" id="message">
// put this in Javascript in for when the user has submitted the form

below is my code..

<?php
$server = 'localhost';
$user = 'root';
$password = '';
$database = 'studentaccount';
$con = mysql_connect ($server,$user,$password);
$db = mysql_select_db($database);
 if (!$db || !$con)
 {
     die ('<h3>SERVER DOWN BE BACK LATER</h3>');
 }
 else
     {
     $user_id=$_GET['user_id'];
     $query = "SELECT * FROM users WHERE user_id=$user_id";
     $result = mysql_query($query);
     $records = mysql_fetch_array($result);
     //$cur_prev = $records ['previledge'];
     //echo $user_id;


     if (isset($_POST['update']))
     {
            $uname = strtoupper($_POST ['uname']);
            $prev = strtoupper($_POST ['prev']);
            $user = md5($_POST ['user']);
            $pass = md5($_POST ['pass']);
            $date = date("Y-m-d");
            $repeatpass = md5($_POST ['repeatpass']);
           // echo "$uname/$prev/$pass/$date/$repeatpass";
            $user_box = $_POST ['user'];
            $pass_box = $_POST ['pass'];
            $repeat_box = ($_POST ['repeatpass']);

            $query = "UPDATE users 
                      SET name='$uname',
                        previledge ='$prev',
                        password = '$pass',
                        date = '$date'
                      WHERE user_id = '$user_id';";

            if (($user_box)=='' || ($pass_box)=='' || ($repeat_box)=='')
            {

Try this, there is probably an easier way to just attach a function and onclick to your submit but try that :)

<?php
$server = 'localhost';
$user = 'root';
$password = '';
$database = 'studentaccount';
$con = mysql_connect ($server,$user,$password);
$db = mysql_select_db($database);
if (!$db || !$con)
{
die ('<h3>SERVER DOWN BE BACK LATER</h3>');
}
else
{
$user_id=$_GET['user_id'];
$query = "SELECT * FROM users WHERE user_id=$user_id";
$result = mysql_query($query);
$records = mysql_fetch_array($result);
//$cur_prev = $records ['previledge'];
//echo $user_id;


if (isset($_POST['update']))
{
?>
<script type="text/javascript">
var input = document.getElementById('user');
input.value="";
</script>
<?
$uname = strtoupper($_POST ['uname']);
$prev = strtoupper($_POST ['prev']);
$user = md5($_POST ['user']);
$pass = md5($_POST ['pass']);
$date = date("Y-m-d");
$repeatpass = md5($_POST ['repeatpass']);
// echo "$uname/$prev/$pass/$date/$repeatpass";
$user_box = $_POST ['user'];
$pass_box = $_POST ['pass'];
$repeat_box = ($_POST ['repeatpass']);

$query = "UPDATE users 
SET name='$uname',
previledge ='$prev',
password = '$pass',
date = '$date'
WHERE user_id = '$user_id';";

if (($user_box)=='' || ($pass_box)=='' || ($repeat_box)=='')
{
echo "ALL FIELDS ARE REQUIRED!";
}
else if(($pass)!= ($repeatpass))
{
echo "PASSWORD MISMATCH";
} 
else 
{ 
$result = mysql_query($query);
if ($result)
{
echo "SUCCESSFULLY SAVED!";
}
else
{

echo "SAVE FAILED";
} 
}
} 
if (isset($_POST['delete']))
{


$query = "DELETE FROM users
WHERE user_id = '$user_id'";
$result = mysql_query($query);


if ($result)
{
echo "Successfully Deleted!";
}
else
{
echo "Delete Failed!";
}

}
}
?>



<form method="POST" action="" >
<table align="center">
<tr>
<td>Name:</td>
<td><input type="text" name="uname" value="<?php echo$records['name'];?>"></td>
</tr>
<tr>
<td>Previledge:</td>
<td>
<?php
$query = "SELECT * FROM previledges";
$result = mysql_query($query);
echo "<select name='prev'>";
while($records = mysql_fetch_array($result))
{
echo "<option>{$records ['prev_desc']}</option>";
}
echo "</select>";
?>
</td>
</tr>
<tr>
<td>Username</td>
<td><input type="text" name="user" ></td>
</tr>
<tr>
<td>Password</td>
<td><input type="password" name="pass"></td>
</tr>
<tr>
<td>Repeat Password</td>
<td><input type="password" name="repeatpass"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="update" value="Update" ><input type="submit" name="delete" value="Delete"></td>

</tr>
</table>

</form>
