Checkboxes value to be stored in the database

Hii friends,
I have written following code in the profile form creation part...

form name="form1" method="post">
table>
tr>
td>input type="checkbox" name="chkBox" value="1">

td>Architecture

td>input type="checkbox" name="chkBox" value="2">

td>Art

td>input type="checkbox" name="chkBox" value="3">

td>Business

td>input type="checkbox" name="chkBox" value="4">

td>Community

/tr>

tr>
td colspan="2">

/tr>
/table>
input type="hidden" name="allBoxes" value="1,2,3,4">
*/

i want this checkbox values to be stored in the database and also can be retrieved next time ... while editing

How can I do it?

Thanks in advance...
