Re: FN-FORUM: Displaying tabular data across recordsets.

date posted 10th September 2007 12:13

The alternative is to do the check on the recordset within the =20
server-side code (whether ASP or PHP)

Create two variables called (for example) old_val and new_val
At the start of the loop, set new_val to the course code.
When you're printing the first part of the row (i.e. the course code) =20
then use the following (pseudo-code) if/then...





That way, if the course code has changed, it'll print the new course =20
code. If not, it'll print nothing, and you'll have an empty cell.

Hope that helps.

Me.
