Re: [WEB400] Can CGI Do this ???

[Rich Duzenbury <rduz@xxxxxxxxxxxxxxxxxxx>]

CGI doesn't have a subfile concept.  You are on the right track in that you
need to check all fields for changes.

If you need to check for differences, one way might be to output your data
field to an inputbox as you are currently doing, and then under a similar
name output the data field to a hidden field.  They will both be returned
when the form is posted, and you could then check them for differences.  If
a difference is found, post the changes for that record to your database.

Another possibility would be to compute and store a checksum for each
record in a hidden field tied to your record.  When the form is posted,
calculate a checksum for each posted record, and then compare the two
checksums.  If the checksums are different, post the record to your database.
