exists as we're relying on it." You can also also do other things with it
but that's the basic deal.
Here's a custom tag I knocked together this morning which is similar to
cfparam but a bit more featureful. You call it like this:
<cf_param name="attributes.chunksize" type="numeric" default="10" min="1"
max="100">
Instead of throwing an error it simply fixes up the data. It's not very
tested but feel free to play. There're probably better versions around.
<cfparam name="attributes.name" type="string">
<cfparam name="attributes.type" type="string" default="">
<cfparam name="attributes.min" default="">
<cfparam name="attributes.max" default="">
<cfif structkeyexists(caller, attributes.name)>
<cfset value = caller[attributes.name]>
<cfelseif structkeyexists(attributes, "default")>
<cfset value = attributes.default>
<cfelse>
<cfset value = "">
</cfif>
<cfif attributes.type eq "numeric">
<cfset value = val(value)>
</cfif>
<cfparam name="value" type="#attributes.type#">
<cfif attributes.type eq "numeric">
<cfif len(attributes.min)>
<cfif value lt attributes.min>
<cfset value = attributes.min>
</cfif>
</cfif>
<cfif len(attributes.max)>
<cfif value gt attributes.max>
<cfset value = attributes.max>
</cfif>
</cfif>
</cfif>
<cfset caller[attributes.name] = value>

Where do you set the cfparam? In the receiving template such as
<cfparam name="exp_months" default="">
I've always struggled with CFPARAM

The standard way is a cfparam.

Subject: passing empty form field entry
If a web site visitor completes a form without entering data in a field
(which in this case may be OK), how do you set up the coding for
inserting that "blank" entry into a database (or ignoring that field).
If I include the field in the SQL insert statement, I get an error
"resolving parameter"
I'm trying to avoid a bunch of CFIF statements (ie. CFIF "field EQ '',
then such and such CFELSE such and such)
TIA
Tim
