You're basically abusing the to have a button with a background image. The represents an image map. The mouse position on the button is been sent as cmd_delete.x and cmd_delete.y parameters. But you are not interested in the mouse position. Replace it by a normal and use CSS to specify a background image. E.g.

with

input.delete {
    background-image: url('bin/images/common/delete.png');
    width: 20px;
    height: 20px;
    border: 0;
    cursor: pointer;
}

and check it as follows

if (isset($_GET['cmd_delete'])) {
    // Delete button pressed.
}
