Hi Rich,
Yes it can be done. What I understand that want to do is to ensure that there
is something returned from the database when the user submits the form, and
that this result is then passed to a hidden field on the ack page (which can
be a second form if you want).
Set your config file as per normal for the dbfetch plugin, and in the rules
file use the following rule.
REQ ($PHORM_DBFRSLT[NUM]['NAME'] == "") >> non_existant_field >> 1
No result returned from database
###
Explanation: This is a conditional REQ. What it says is, if there is nothing
in the column name specified of the specified record, then the information in
a field that does not exist is required. This of course will cause the error,
as there is nothing in that non-existant field. Please note the quote
characters in the conditional section. These are required as that is a php
condition, not a Phorm parsed condition. (like $_GET['foo'])
On your ack page use {{PHORM_DBFRSLT[NUM][NAME]}}
In both cases, NUM and NAME should be replaced with the record number and the
database column name respectively, and >> should be replaced with the tab
character.
Hope this helps,
