Find empty value on structure

[Guest]

I'm assigning values to my structure dynamically and I need to find if one or more of the value(s) is/are empty string value
I tried to use :
<cfset aResults = #StructFindValue(mystruct,"", "all" )#> and I got what I wanted but now I'm not sure how can I refer back to the Key for those empty value(s)?

For example if this is my structure:
<CFSET str_mystruct= structNew()>
<CFSET str_mystruct["FN"}="Sylvia">
<CFSET str_mystruct["LN"}="Smith">
<CFSET str_mystruct["Add"}="">
<CFSET str_mystruct["City"}="Bladensburg">
<CFSET str_mystruct["zip"}="">

The StructFindValue function found 2 keys with empty values,they are Add and Zip
what is the syntax for CFIF condition, for example if Add or Zip keys is "" do something?

Perhaps a better place for that if/else logic would be as you are populating the structure.

Get the array of results from the function then loop over that array. The array will only contain results for blank keys. So something like:

<cfloop from="1" to="#ArrayLen(Variables.aResults)#" index="ARY">
<!--- Lets reset the blanks --->
<cfset str_mystruct[Variables.aResults[ARY]['key']] = 'blank' />
</cfloop>

If you want to remove all the empty keys form your structure, you can make use of the "RemoveEmptyStructureKeys" UDF...
