Re: finding dynamic form fields after submission
and this should hold true for the other three variables po_, role_ and year_
here's the loop again with the suggested changes
For (i=1;i LTE Form.PE_Counter; i=i+1)
if(StructKeyExists(FORM,'play_'&i)){
session.NODA09_formStruct['play_'&i] = form['play_'&i];
}
if(StructKeyExists(FORM,'po_'&i)){
session.NODA09_formStruct['po_'&i] = form['po_'&i];
}
if(StructKeyExists(FORM,'role_'&i)){
session.NODA09_formStruct['role_'&i] = form['role_'&i];
}
if(StructKeyExists(FORM,'year_'&i)){
session.NODA09_formStruct['year_'&i] = form['year_'&i];
}
it seems to stop after the first if statement, even when the key/value
pair exists in FORM

Re: finding dynamic form fields after submission
I tried this method, the looping *seems to be working*
For (i=1;i LTE Form.PE_Counter; i=i+1)
if(StructKeyExists(FORM,'play_#i#')and
Trim("Form.play_#i#") IS NOT ''){
session.NODA09_formStruct.play_[i] = form[play_[i]];
<- error is in this line
}
However this code throws the following..
You have attempted to dereference a scalar variable of type class
java.lang.String as a structure with members.
When I start playing around with the bracketing, it starts throwing CF
errors...

Re: finding dynamic form fields after submission
As well as the form.fieldNames sugested by Barney and Charlie. Since the form and url scopes are structures, as are all variable scopes in CF, you can use any of the structure functions or tags to parse the data. Such as: #structKeyList(form)# OR #structKeyList(url)# OR #form[field]# OR #url[field]# ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:316997 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

The way I do this is to have each form field have an underscore in it.

Re: finding dynamic form fields after submission
you can loop over the form.fieldnames value to get the list of fields. or as your form is dynamically generating the fields, update a hidden value with the # of current fields. on the action page, loop from 1 to the value of that hidden field and generate the names dynamically (e.g. form['po' & loopIndex]) On Fri, Dec 19, 2008 at 11:57 AM, Scott Stewart wrote: > Hey all, > > I have a form with one of those wonderful dynamic "ad form row" widgets. > Because of this I never will know exactly what fields will be sent for > processing... > > the original four fields in the row are called "play", "po", "role", and > "year", the javascript generates "play1", "po1", "role1" and "year1" or > 2, or 3 ad Infinitum based on how many rows the user has selected. > on the processing side I need to write the form field values to a > structure because there will be credit card processing before I write to > the database. > > How can I loop over the form structure and find the dynamically > generated form fields and their values. > > -- > Scott Stewart > ColdFusion Developer > > Office of Research Information Systems > Research & Economic Development > University of North Carolina at Chapel Hill > > Phone:(919)843-2408 > Fax: (919)962-3600 > Email: saste...@email.unc.edu > > > > ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:316994 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
