to read multiple cfreturn

[capik79]

Hi All,

I'm just exploring the CF component function. I've face oe problem which is to
read more than1 cfreturn. Here the code and file name :

File name : currency.cfc
<!--- File name Currency.cfc --->
<!--- componet file to change currency --->


<cfcomponent name="currency_converter">
<cffunction name="curr_converter" access="remote" returntype="any">
<cfargument name="country">
<cfargument name="myr">
<cfquery name ="get_val" datasource="ScratchDB">
Select curr from currency
Where Currency_type = '#arguments.country#'
</cfquery>
<cfset curr_val = #arguments.myr#*#get_val.curr#>
<cfset country_curr =#get_val.curr#>

<cfreturn curr_val>
<cfreturn country_curr>
</cffunction>
</cfcomponent>

CF file : currency_converter.cfm

<cfoutput>
<cfset curr_req = #form.val#>
<cfset curr_country =#form.country#>
<cfinvoke component="currency" method="curr_converter"
returnVariable="final_val">
<cfinvokeargument name="country" value="#curr_country#">
<cfinvokeargument name="myr" value="#curr_req#">
</cfinvoke>
<cfinvoke component="currency" method="return_currency"
returnvariable="cntry_val">
</cfinvoke>

<br>
<br>Original Currency : #curr_country#
<br>Original Value : #curr_req#
<br>RM 1 = #cntry_val# <!--- this value wil return from cfc file, cfreturn
country_curr --->
<br>Malaysia Value : RM #final_val#
<br>

</cfoutput>

now my program only read <cfreturn curr_val>, not <cfreturn country_curr>.
So is it possible to return more than 1 data in one function?

thanks in advance

return what you need as an array or structure.

[capik79]

Thx Paul,

Can you provide me an example for that.
Array in cffunction and how do I grab in cfinvoke.

Thanks
Shaffiq

[PaulH]

a structure might be a better choice.


<cfcomponent name="currency_converter">
<cffunction name="curr_converter" access="remote" returntype="struct">
<cfargument name="country" required="Yes" type="string">
<cfargument name="myr" required="Yes" type="numeric">
<cfset var thisCurrency=structNew()>
<cfset var curr_val=0>
<cfset var country_curr="">
<cfquery name ="get_val" datasource="ScratchDB">
SELECT curr
FROM currency
WHERE Currency_type = '#arguments.country#'
</cfquery>
<cfset thisCurrency.curr_val = arguments.myr*get_val.curr>
<cfset thisCurrency.country_curr =#get_val.curr#>
<cfreturn thisCurrency>
</cffunction>
</cfcomponent>

<cfinvoke component="currency" method="curr_converter"
returnVariable="final_val">
<cfinvokeargument name="country" value=curr_country>
<cfinvokeargument name="myr" value=curr_req>
</cfinvoke>

<cfoutput>
#final_val.curr_val#
<br>
#final_val.country_curr#
</cfoutput>

Try using a Stucture
Change
<cfreturn curr_val>
<cfreturn country_curr>

Change the return type on your <cffunction> to returntype="struct"
then do something like this
<cfscript>
returnObj = StructNew();
returnObj.curr_val = #curr_val#;
returnObj.country_curr = #country_curr#;
</cfscript>
and return the structure
<cfreturn returnObj>

Back in your currency_converter.cfm page you can output #final_val.curr_val#
and #final_val.country_curr#.
