How Do I Index a Variable During a CFloop? 1

[3dColor]

Instead of repeating the same code over and over 15 times:

<cfif GetNewImages.photo1 NEQ "">
	- Lots of code to process the image on to my server -
</cfif>

<cfif GetNewImages.photo3 NEQ "">
	- Lots of code to process the image on to my server -
</cfif>

<cfif GetNewImages.photo4 NEQ "">
	- Lots of code to process the image on to my server -
</cfif>

    ...repeat until 15

I would rather do something like this:

<cfloop
    index="image"
    from="1"
    to="15"
    step="1">

    <cfif GetNewImages.photoX NEQ "">
		- Lots of code to process the image on to my server -
    </cfif>
    
</cfloop>

But how do I loop through the variable GetNewImages.photoX 15 times?

GetNewImages.photo1
GetNewImages.photo2
GetNewImages.photo3
etc.

the index name is image, so you would write...

<CFIF Evaluate("GetNewImages.photo" & #image#) NEQ "">

Thanks Rudy, I really appreciate it!

or you can avoid evaluate which has a lot of overhead and use structure syntax.

ex.

<cfset x = evaluate("form.fieldName" & i)>

would be

<cfset x = form["fieldName" & i]>

or

<cfset x = form["fieldName#i#"]>

I prefer the first alternative syntactically; however, the second option is a bit more efficient according different concatenation tests I've run.

In the case of your query you would want to use

<cfif variables.getNewImages["photo#image#"][getNewImages.currentRow] neq "">

if getNewImages isn't a query you would simply use

<cfif variables.getNewImages["photo#image#"] neq "">

Yes, associate array notation is preferred. But as an aside, the naming convention does raise questions about the table structure ..
