I actually have an example for this kind of form. Say I have two Records, Person 124 and Person 532.
Well come to find out, record 124 and 532 are the exact same person who signed up twice. I want to merge the two records together and leave with just one, but oh noes 532 has more up to date info than 124. So I want to display both records, side by side, with some radio buttons A and B for each record. If the radio button has A as a value when it comes in, I take from Record A( in this case, Person 124)., If the radio button has a value of B, I take record 532. So in this case, I cannot use SQLFORM (I could, but its much easier to just use a manual form, and manually validate the request.vars) -Thadeus On Thu, Apr 1, 2010 at 6:34 PM, Yarko Tymciurak <resultsinsoftw...@gmail.com> wrote: > On Apr 1, 5:04 pm, carlo <syseng...@gmail.com> wrote: >> sorry for this "out of sync" answer but though I managed some "tricks" >> to tackle the (problem of) validation in pure html forms during these >> years, I would be curious about an answer to Mengu's request of >> "showing how to make validation with manual forms". > > When I need to do this, I do it with making a memory-based table, and > SQLFORM or SQLFORM.factory, and do whatever validation I need. > >> >> Sorry DenesL but you did not answer the question as you supposed a >> model in place, so I would really appreciate a simple html form which >> preserves validation.
