Why use eval at all?
<cfloop from="1" to="20" index="i">
<cfif structKeyExists(form, 'post#i#_data')>
<cfset variables['column_#i#'] = form['post#i#_data']>
</cfif>
</cfloop>

Any time you have nested hash marks, that's a good sign things aren't
right. Replace
<cfset column_#i#="#evaluate("post#i#_data")#">
with
<cfset "column_#i#" = evaluate("post" & i & "_data")>
or
<cfset Variables["column_#i#"] = evaluate("post" & i & "_data")>
or
<cfset Variables["column_" & i] = evaluate("post" & i & "_data")>
Or consider using an array for your column values.
