ColdFusion ListToArray - includeEmptyField
Most ColdFusion developers have probably realized at some point that ListToArray ignores empty values between delimiters altogether. What I mean is that "a,,,b,c,d" would return an array with only 4 items in it, rather than 6 items with two of them being empty. This has been frustrating to say the least. ColdFusion 8 to the rescue, ListToArray now has a third arguments "includeEmptyField" that defaults to false, but if true will not ignore empty values. See the following code for an example:
ColdFusion:
-
<cfset letters="a,,,b,c,d" />
-
<cfdump var="#listToArray(letters,',',true)#" label="listToArray(letters,',',true)" />
-
<cfdump var="#listToArray(letters,',',false)#" label="listToArray(letters,',',false)" />
The above code results in the following output. Nothing unexpected here, but a welcome addition nonetheless.
I really have to read the docs better, I missed that extra attribute that was passed in.
very cool
I agree it is cool. However, I also maintain this is more of a fix than an enhancement since to me it seemed crazy that there was no way to account for blank values before outside of replacing empty values with a arbitrary value.
