删除个人资料请求？

I am a newbie trying to delete a profile but this message pops up in address bar

http://thexyz.com/the/delete.php?id=1>

Am I making any syntax mistake my code is as below-

<?php 
    $i=1; 
    while($row=mysql_fetch_array($rw)) { ?>
        <tr>
            <td><?php echo $i; ?></td>  
            <td align="center">
                <a href="delete.php?id=<?php echo $row['Customer Id']; ?> "onclick="return chkstatus();">
                <img src="resources/images/icons/user_delete.png" width="16" height="16"/></a>delete
            </td>

Even delete is not working

My delete.php code is

<?php
    session_start();
    if($_SESSION['username']=="");
        include_once('db.php');

    if( isset($_GET['del']) ) {
        $id = $_GET['del'];
        $sql= "DELETE FROM opd WHERE Sno='$Sno'";
        $res= mysql_query($sql) or die("Failed".mysql_error());
        echo "<meta http-equiv='refresh' content='0;url=index.php'>";
    }
?>

You have to remove the > after ?>

Your <a href should look like this:

<a href="delete.php?id=<?php echo        
$row['Customer Id']; ?>" onclick="return chkstatus();">

In your delete.php

if($_SESSION['username']==""); // IT will do nothing here

above code will not do anything because your have terminated statement with semicolon ;

You are passing id not del.

so $_GET['del'] should be changed as $_GET['id']

$sql= "DELETE FROM opd WHERE Sno='$Sno'";

changed to

 $sql= "DELETE FROM opd WHERE Sno='$id'";
