checkbox + sql

[nominator]

hi, i am doing a member system. at the admin panel which have a list of user, has a checkbox each at the side. I did a loop to display all user from db and set the checkbox value to the id accordingly

[code]
$result =mysql_query("Select * from staff");
if($myrow = mysql_fetch_array($result));
{
do{
printf("             <tr>
                <td width=100><span class=text>%s</span></td>
                <td width=100><input type=checkbox name=check value=%s></td>
             </tr>",$myrow[name],$myrow[staff_id]);
            
}while($myrow=mysql_fetch_array($result));
}[/code]

then for my action delete,

[code]    if($action == 'delete')
    {
        $check = $_POST['check'];
        connect();
        mysql_query("Delete from staff where staff_id='$check'");
    }[/code]

i select a few user to delete, but it only delete one...how can i make it delete whatever i checked.
