[cfaussie] RE: How To Determining if specific Variable Arrays exist

Fri, 30 Jan 2004 17:09:36 -0800

when I use the arraylen() function eg:
 
<cfif ArrayLen(aTDWDoc.atdw_data_results.product_distribution.product_record.max_star_rating.XmlText) LTE i>
 
generates the following error message
 
(I need to include "product_record.max_star_rating" ) as that is the specific array element I am testing for to see whether it exists hence the reason for initially trying to use isdefined() function
 
Object of type class java.lang.String cannot be used as an array
 
The error occurred in D:\inetpub\webhost\4301\www\aus\ATDW\query_products_26_01_04.cfm: line 60
58 :       <cfset prodn = QuerySetCell(myquery, "product_description", aTDWDoc.atdw_data_results.product_distribution[i].product_record.product_description.XmlText, i)>
59 : 	  </cfif>
60 : 	  <cfif ArrayLen(aTDWDoc.atdw_data_results.product_distribution.product_record.max_star_rating.XmlText) LTE i>
61 :       <cfset prodn = QuerySetCell(myquery, "star_rating", aTDWDoc.atdw_data_results.product_distribution[i].product_record.max_star_rating.XmlText, i)>
62 : 	  </cfif>

You cant use isDefined() for arrays
 
You could try using ArrayLen
 
so
 
<cfif ArrayLen(aTDWDoc.atdw_data_results.product_distribution) LTE i>
<cfset prodn = QuerySetCell(myquery, "star_rating", aTDWDoc.atdw_data_results.product_distribution[i].product_record.max_star_rating.XmlText, i)>
</cfif>

That might do you

I am trying to use the isdefined function to determine with a variable within an array exists. The code is in bedded within the cfloop with index=I
 
when using the syntax in line 60 below the following error message occurs
 
wondering what is the correct syntax in order to be able to determine whether specific variables within the are defined.
 
I look forward to your input
 

Parameter 1 of function IsDefined, which is now &quot;aTDWDoc.atdw_data_results.product_distribution[i].product_record.max_star_rating.XmlText&quot;, must be a syntactically valid variable name.

The error occurred in D:\inetpub\webhost\4301\www\aus\ATDW\query_products_26_01_04.cfm: line 60
60 : 	  <cfif  isdefined('aTDWDoc.atdw_data_results.product_distribution[i].product_record.max_star_rating.XmlText')>
61 :       <cfset prodn = QuerySetCell(myquery, "star_rating", aTDWDoc.atdw_data_results.product_distribution[i].product_record.max_star_rating.XmlText, i)>
62 : 	  </cfif>
