Question

Firstly, apologies for the phrasing in the question – I couldn’t come up with anything better, sorry!

Here’s the scenario – I’m working with a JS Front-end that I have little control over, and a Coldfusion backend that I do control.

Everything is working fine, with one slight exception – which I’m hoping will be an easy fix! The database currently stores only the filename of an image, however the front-end requires the full url. Therefore, I somehow need to append the domain (which will always be the same) prior to SerializeJson. I’ve tried a few things without success so far, and haven’t been able to find any syntax examples.

My existing code is below;

<cfquery name="qryNames">
    SELECT ID, imgthumb, imgfull 
    FROM   images 
    ORDER BY ID DESC
</cfquery>

<cfset data = [] />

<cfoutput query="qryNames">
    <cfset obj = {
                   "thumb" = ImgThumb,
                   "image" = Imgfull
                 } />
    <cfset arrayAppend(data, obj) />
</cfoutput>

<cfprocessingdirective suppresswhitespace="Yes">
<cfoutput>
    #serializeJSON(data)#
</cfoutput>
</cfprocessingdirective>

<cfsetting enablecfoutputonly="No" showdebugoutput="No">

For clarity, this is what I’m looking for…

<cfset obj = {
                "thumb" = http://mydomain/ImgThumb,
                "image" = http://mydomain/Imgfull
    } />

Pointers much appreciated!

You can append things to variables like this:

<cfset newThumb = "http://mydomain/"&ImgThumb>
<cfset newImage = "http://mydomain/"&Imgfull>

Hopefully that works for you.
