Outputting number of form fields submitted as well as values

[infocusweb]

Hi Folks - How do I output the number of form fields submitted as well as the form field values? Thanks in advance.

#ListLen(FORM.fieldnames)#

will give you the total number of form fields submitted, whether they had a value or not. (it will also give you all named field elements, if your submit button has a name attribute- it will be counted)

if you only want to count fields with values, you can do this

<cfset fieldcount = 0>

<cfloop list="#FORM.fieldnames#" index="i">

	<cfset current_field = "FORM." & #i#>
	<cfset current_value = Evaluate(#current_field#)>
	
		<cfif Len(#current_value#)>
			<cfset fieldcount = fieldcount + 1>
		</cfif>
		
</cfloop>
<br>
<cfoutput>#fieldcount#</cfoutput>

I realize there is probably a much more efficient way of getting the form value, but it's late and this is all i can come up with.

Hi,

As MX returns scopes as a structure you can use the collection attribute of the cfloop and iterate through them like this:

<CFLOOP COLLECTION="#Form#" ITEM="i">
<CFOUTPUT>
#i#&nbsp;&nbsp;#Form#<br>
</CFOUTPUT>
</CFLOOP>

This will mean that you then don't have to use the slow Evaluate function as well, which MM recommends to avoid.

I am not sure if you care about the format, but if you just want a list of form fields and their values for debugging purposes, you can use cfdump:

<cfdump var="#FORM#">
