Form submission uses only the element name; jQuery and other
JavaScript/DHTML references, as well as HTML certification, require a
unique ID.
These 2 can be set independently and still work correctly.
As Klaus said, having the IDs as non-unique is adding problems for yourself.
If you can get the database to generate the form element's "*name*" tag
but add some sort of unique prefix/suffix to the form's "*id*" tag, you
should be OK; simply reference the unique ID (prefix/suffix + the
original name) when using jQuery.
