Question

I have the following array with a structure within each array (see this jsfiddle for what the array looks like).

How do I loop over the array, then get the structure within the array to pull out the userid? I keep getting errors with variations that I’ve tried. The most common error I’m getting is:

Must be a valid structure or COM object

Here is the code I have to loop over the array and structure that is generating the error above (see this jsfiddle for what the array looks like).

<cfloop from="1" to="#ArrayLen(getTeamDetails)#" index="s">
    #s#) #getTeamDetails[s][uid]#<br>   
</cfloop> 

Mark asked for some more code so I’ve included how I’m populating the array/structure:

<cfoutput query="getTeam">
    <cfset getTeamDetails[getTeam.currentrow] = StructNew()>
    <cfset a = StructInsert(getTeamDetails[getTeam.currentrow], "firstname", getTeam.firstname, 1)>
    <cfset a = StructInsert(getTeamDetails[getTeam.currentrow], "lastname", getTeam.lastname, 1)>
    <cfset a = StructInsert(getTeamDetails[getTeam.currentrow], "uid", getTeam.uid, 1)>
</cfoutput>

Answer 1

I think this should work:

<cfloop from="1" to="#ArrayLen(getTeamDetails)#" index="s">
    #s#) #getTeamDetails[s].uid#<br>   
</cfloop> 

I created your array and structure from scratch and loop through it to access the structkey you need to access.

<cfscript>
ThisArray = arrayNew(1);
for (i = 1; i lte 3; i=i+1) {
    ThisStruct = structNew();
    ThisStruct.UID = "123";
    arrayAppend(ThisArray, ThisStruct);
}
for (i = 1; i lte arrayLen(ThisArray); i=i+1) {
    ThisOutput = "#i#) #ThisArray[i].UID# <br>";
    writeOutput(ThisOutput); 
}
</cfscript>
