Re: Loop over field names
Right but that doesn't help if the field names are username_1, id_1, username_2, id_2, etc. He needs to be able to organize multiple sets of form data into the proper format on the server. Simply looping over the form scope won't help with that. The hard way is to loop over the form data and try to parse and extract the separate sets of data. The easy way is to use my Form Utilities component that I mentioned earlier, which will create the proper data structures automatically.

Loop over field names
Hi All, Having brain freeze on this... Basically have a form, part of the form is populated from a query within an unknown number of field elements. The form code snippet would look something like this. cfoutput query=someQuery input name=anID#currentRow# value=#anID# / input name=someField#currentRow# value=#someFieldValue# / input name=otherField#currentRow# value=#otherFieldValue# / /cfoutput I want to be able to take the form and run either update or creates for the form. How would I go about referencing the form fields to insert/update my DB?

RE: Loop over field names
A few ways, pass the record count along in a hidden field then loop: cfloop from=1 to=#FORM.recordCount# index=i cfoutput#FORM[anID i]#/cfoutput /cfloop Or requery on the next page and work out the record count there. Or do a conditional loop with an IsDefined(FORM.anID#i#) and a counter to increment i.

RE: Loop over field names
Use the same query to loop over them again and reference them such as... cfloop query=someQuery #form[anID currentRow]# #form[someField currentRow]# #form[otherField currentRow]# /cfloop -Original Message- From: Richard Cooper [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 15, 2008 7:14 AM To: CF-Talk Subject: Loop over field names Hi All, Having brain freeze on this...

Re: Loop over field names
You can also just use my Form Utilities component ( http://formutils.riaforge.org/) to automatically translate array or structure notation into complex data structures on the server side. So it would become: cfoutput query=userQuery input name=user[#currentRow#].userID value=#userID# / input name=user[#currentRow#].firstName value=#firstName# / input name=user[#currentRow#].lastName value=#lastName# / /cfoutput And on the server you get back an array of structures. So assuming the query had 3 rows, you'd get an array named user with three elements. Each element would be a structure with keys of userID, firstName, and lastName, with the appropriate values. It beats the heck out of trying to parse out numbers from field names! :-) On Tue, Jul 15, 2008 at 7:14 AM, Richard Cooper [EMAIL PROTECTED] wrote: Hi All, Having brain freeze on this...

Re: Loop over field names
Another idea is instead of naming them like you intend with the currentRow: cfoutput query=someQuery input name=anID#currentRow# value=#anID# / input name=someField#currentRow# value=#someFieldValue# / input name=otherField#currentRow# value=#otherFieldValue# / /cfoutput Give the form fields that have the same data the same name, removing the currentRow appendage: cfoutput query=someQuery input name=anID value=#anID# / input name=someField value=#someFieldValue# / input name=otherField value=#otherFieldValue# / /cfoutput In JavaScript these fields that are named the same are treated as an array. You can have a hidden form field or write out a JavaScript variable with the number of records in the query: var numberOfRows = #someQuery.recordcount# - 0; // - 0 is a trick to indicate variable is numeric function someFunction() ( var row3 = document.myForm.anID[2].value; // JavaScript arrays are 0 based ) On the server side when the form is submitted, ColdFusion treats these form fields that are named the same as a list: cfset row3 = ListGetAt(anID, 3, ,) Hope this helps.
