Deleting multiple items from database using checkboxes

Hi people,. I have a guestbook admin page were i would like to delete one item or more items from the database if necessary. I have modified my normal guestbookpage so that it has checkboxes in front of every entry. This is my code: <input type=\"checkbox\" name=\"dele[]\" value=\"".$sql['entryID']."\"> Now i can select multiple items. But i have tried to delete em, but it only deletes one item from the database, my query looks like this : DELETE FROM gastenboek WHERE entryID=$dele . Can anyone help me. Thanks for your time.
