I have the following constract when parsing .json file:

<cfset line_items = jsonData.order.line_items>

<cfloop array="#line_items#" index="line_item">

<cfset line_item_sku = #line_item.sku#>

</cfloop>

This time, for some reason "sku" is not defined (Element SKU is undefined in LINE_ITEM.). Question: how do I make sku = 'XX' if it's not defined. I've tried Elvis notation, but without success (<cfset line_item_sku = #line_item.sku#?:"XX">)

I would use use

structKeyExists()

to check if it exists in the struct. BTW, you don't need the pounds (

#...#

) around the variable when you are setting

line_item_sku

.

You can use a safe navigation operator. This tries to use the json value and if it doesn't exist will return your default value

<cfset line_item_sku = line_item?.sku ?: 'XX'>

Thank you all for your replies. Question about # signs. I thought I need them because I am setting line_item_sku to then "value" of line_item.sku, so I'd need inclose it into #s.

If you're not within a string literal, you don't need it.

<cfset mystring = "My name is #name#" />

<cfset myOtherString = aVariable />

Thanks again. I can only imagine how many of those I need to remove :-)
