How is an array structure sort executed?

[Guest]

I have created a one dimension array structure with the structure elements of id number and matches. I want to collect all of the id numbers and loop through all of the matches. When the matching criteria is finished, I would like to show the id numbers with the most matches. How do I sort a structured array? I have tried the following:

<cfset applicant_array = arraynew(1)>
...start matching loop...
,,,
<cfset applicant_array[idx] = StructNew()>
<cfset applicant_array[idx].matches = applicant_array[idx].matches+1>
<cfset applicant_array[idx].id = #applicant2characteristic.applicant_id#>
...end matching loop

<cfset temp=#ArraySort(applicant_array, "text", "desc")#>

The sort fails because it is on a structure. I tried using the structure element, but that fails as well. Is there a command for sorting a structure array by a specific element?

TIA,

Jim

So you have an array of structures, if I understand you correctly. If so, this code should work to sort that array based on the number of matches:

<cfset a = ArrayNew(1) />
<cfset a[1] = StructNew() />
<cfset a[1].id = "1" />
<cfset a[1].matches = "3" />
<cfset a[2] = StructNew() />
<cfset a[2].id = "2" />
<cfset a[2].matches = "4" />
<cfset a[3] = StructNew() />
<cfset a[3].id = "3" />
<cfset a[3].matches = "1" />

<cfloop from="1" to="#ArrayLen(a)#" index="i">
<cfloop from="#i#" to="#ArrayLen(a)#" index="j">
<cfif a .matches LT a.matches>
<cfset ArraySwap(a, i, j) />
</cfif>
</cfloop>
</cfloop>
