How to loop over all form fields, setting blank fields to "Null"
Posted on 2004-08-10
So far I have this:
<cfloop collection="#Form#" item="ThisField">
<cfif len(form[ThisField]) LT 1>
<cfoutput>
#ThisField# is blank<br>
</cfoutput>
<cfelse>
<cfoutput>
#ThisField# is populated<br>
</cfoutput>
</cfif>
</cfloop>
Which outputs the field name and if populated or blank.
How can I set the VALUE of each blank field to "NUll" or "EMPTY" or anything?
Should I be using a list?
<cfloop collection="#Form#" item="ThisField">
<cfif len(form[ThisField]) LT 1>
<cfoutput>
#ThisField# is blank<br>
</cfoutput>
<cfelse>
<cfoutput>
#ThisField# is populated<br>
</cfoutput>
</cfif>
</cfloop>

This should do it:
<CFLOOP LIST="#form.fieldnames#" Index="field">
<CFIF len(evaluate('form.'&field
<CFSET 'form.#field#' = "NULL">
#field# value is NULL<BR>
<CFELSE>
#field# value is #evaluate(field)#
</CFIF>
</CFLOOP>
<CFLOOP LIST="#form.fieldnames#" Index="field">
<CFIF len(evaluate('form.'&field
<CFSET 'form.#field#' = "NULL">
#field# value is NULL<BR>
<CFELSE>
#field# value is #evaluate(field)#
</CFIF>
</CFLOOP>
