PHP / MySQL简单清单

I currently have an internal intranet form that saves referral information from front line staff and makes it available to back office staff in a simple table. I have been asked to add check boxes to the form so the back office staff will know when certain steps in the referral process have been completed.

My question is, what would be the simplest way to add a check boxes that will stay checked on refresh if the staff has completed a certain step? Any help would be greatly appreciated, the bit of code below is where my table is generated. I have tried everything I can think of to make it work to no avail.

while($row = mysql_fetch_array($data)) {
    echo "<tr>";
    echo "<td><center>" . $row['subDate']   . "</center></td>";
    echo "<td><center>" . $row['mbr_name']  . "</center></td>";
    echo "<td><center>" . $row['acct']      . "</center></td>";
    echo "<td><center>" . $row['mbr_tel']   . "</center></td>";
    echo "<td><center>" . $row['mbr_email'] . "</center></td>";
    echo "<td><center>" . $row['alt_tel']   . "</center></td>";
    echo "<td><center>" . $row['msr_name']  . "</center></td>";
    echo "<td><center>" . $row['type']      . "</center></td>";
    echo "<td><center>" . $row['cata']      . "</center></td>";
    echo "</tr>";
}
