Dynamic form problem

[kelryu]

I have a form that generates dynamic fields that the user can fill. The problem
I'm having is with the form processing. So for example if a user created three
new lines each containing 4 fields of input (eg. name, addr, zip) i need to
check that each line has every single line filled before i process it.

As for now I name every field the same thing but add a number to it, so for
instance if the user creates a new line then the name field is "name1" because
it is in line 1 line 2 would contain "name2".

The problem is in the processing, i have an idea of what i want to do but cant
do it. I create an index loop and loops through but when i try to create
form.name#i# i get an error. The error says form.name does is undefined, so it
does not add the #i# variable to form.name before evaluating. I also tried
form.name&#i# and i still get the same error.

So right now I'm stuck. I dont know how to evaluate the dynamic fields. Any
ideas?

Thanks.

FORM is like a structure. You can access form field values using array
syntax, like:

<cfloop .... index="i">
<cfset localName = FORM["name"& i]>
<cfoutput>#localName#</cfoutput>
</cfloop>

Btw, you may also want to search the forums. Handling dynamic form fields is
a popular question :-)
