RE: Finding matching values in a structure?

[Nick Han]

StructFindValue(us,62|-213) returns an array of match instances, so
you cannot evaluate it in an if statement like that.

Instead, first check for StructFindValue returned value is an array and
loop through it if you had than nested structures.

cfset us = StructNew()
cfset us[andy] = 62|-213
cfset us[jones] = 207|-86
cfset us[cherry] = 42|-220

cfset result=StructFindValue(us,62|-213,ALL)

cfoutput
cfloop from=1 to=#ArrayLen(result)# index=i
 #result[i].key#br
/cfloop
/cfoutput

Subject: Finding matching values in a structure?

I've got a structure containing coordinates for a grid. I've named each
line
for the person who should appear at those coordinates. I've found a
function
called StructFindValue() that says it can do what I need, but
everytime
I try to use it, I get an error.

According to the docs it Searches recursively through a substructure of
nested arrays, structures, and other elements for structures with values
that match the search key in the value parameter..

It says that it returns An array that contains structures with values
that
match the search key value. If none are found, returns an array of size
0.

I determined that I can't use it in a CFIF statement because it returns
an
array. So how would I go about finding a key containing the value?
Here's
my code listed below:

cfset us = StructNew()
cfset us[andy] = 62|-213
cfset us[jones] = 207|-86
cfset us[cherry] = 42|-220

cfdump var=#StructFindValue(us,62|-213)#

cfif StructFindValue(us,62|-213,ALL)
gotcha
/cfif

could do  cfif arraylen(structfindvalue(us,62|-213,ALL)
