Cffunction & cfreturn

First, has anyone used BlogCFC? this is dealing with it.
I have put parts of the pods and main content into iframes.
I now need every link to escape & target the top.
I have a problem with this code it seems...
quote:
<cfoutput><a href="#application.blog.makeLink(id)#"
target="_top">#title#</a><br></cfoutput>
And then in the blog.cfc file I find....
quote:
<cffunction name="makeLink" access="public"
returnType="string" output="false"
hint="Generates links for an entry.">
<cfargument name="entryid" type="uuid"
required="true">
<cfset var q = "">
<cfset var realdate = "">
<cfquery name="q" datasource="#instance.dsn#">
select posted, alias
from tblblogentries
where id = <cfqueryparam cfsqltype="cf_sql_varchar"
value="#arguments.entryid#" maxlength="35">
</cfquery>
<cfif q.alias is not "">
<cfset realdate = dateAdd("h", instance.offset,
q.posted)>
<cfreturn
"#instance.blogURL#/#year(realdate)#/#month(realdate)#/#day(realdate)#/#q.alias#">
<cfelse>
<cfreturn
"#instance.blogURL#?mode=entry&entry=#arguments.entryid#">
</cfif>
</cffunction>
Does anyone see from this why target="_top" does not work?
And am I missing the actual creation of makeLink?
seems like the cffunction just is getting the query for it.
I don't deal with cffunctions.

Both are correct and will work, but cffunction has some
advantages. The biggest one is the cfargument tag which gives you
more control over the datatypes coming in. You could code all those
in cfscript, but it's now unnecessary.

CFFunction CFReturn Strings Chopping Results?

I have a routine that I can run straight up and it will return a list (pipe-delimited) of 1278 results.
I put it in a function in the same program and I get 1278 results.
I put it in a function in its own CFC and I get 279 results.
Anyone ever experienced something like this? I'm sure I'm screwing up somewhere, but this is quite odd. May have to switch to structure or something to test it in another way.
ColdFusion 8 on Windows server 2003.
RLS

Yep, egg on the face. Because this routine had to go to an external API to retrieve results and because that API would only return 500 results at a time, I had to loop through it. Part of my loop included calling another internal function to parse an XML. That internal routine and this one shared a variable, the crucial variable returned with cfreturn.
Oh, well. Let that be a reminder for anyone who stumbles onto this problem/answer on the internet. Declare your local variables! http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=buildingComponents_29.ht ml, see "Function local variables"

Calling CFM from CFC

Greetings to all
I not enough work with ColdFusion.
My question: How I can receive function parametres in *.CFM file from a *.CFC component?
OR
How I can calling functions in CFM from Flex Application?
For example:
In CFM:
<cffunction>
<cfreturn HelloVariable>
</cffunction>
How I can recieve HelloVariable in my Flex Application?
Sorry for my English

In your cfc, add a cfinclude to the cfm file and then you have access to the function.

Don't understand cffunction and cfcomponent

I am trying to alter Forta's ajax related select tutorial to fit my needs. I am having trouble understanding the details of this .cfc though.
<cfcomponent output="false">
    
    <cffunction name="get_states" access="remote" returnType="array">
        <cfset data="">
        <cfset result=ArrayNew(2)>
        <cfset i=0>
        
        <cfquery name="data" datasource="mydsn">
        SELECT id,states
        FROM state
        </cfquery>
        
        <cfloop index="i" from="1" to="#data.RecordCount#">
            <cfset result[i][1]=data.id[i]>
            <cfset result[i][2]=data.state[i]>
        </cfloop>
        <cfreturn result>
    </cffunction>
    
    <cffunction name="get_waters" access="remote" returnType="array">
        <cfargument name="location" type="string" required="true" default="">
        
        <cfset var data="">
        <cfset var result=ArrayNew(2)>
        <cfset var i=0>
        
        <cfquery name="data" datasource="mydsn">
        SELECT id,name
        FROM waters
        WHERE bow_state = '#arguments.location#'
        </cfquery>
        
        <cfloop index="i" from="1" to="#data.RecordCount#">
            <cfset result[i][1]=data.id[i]>
            <cfset result[i][2]=data.name[i]>
        </cfloop>
        
        <cfreturn result>
    </cffunction>
</cfcomponent>
When I put '#arguments.id#' into the second query, I get results. However, I'd like to query by the name instead, so I am trying location. I don't fully understand so I am hacking around with this a bit but I'd like to 1 - get results by name instead of id and 2 - understand the arguments variable so I really know what is going on.
Thanks!

Sorry, didn't see this before I posted.
But I think my suggestion was in keeping with the example. If you need to select on "state", then make the "state" column of your first query to be the first value in the array that you return:

<cfquery name="data" datasource="mydsn">
     SELECT id,states
     FROM state
</cfquery>

<cfloop index="i" from="1" to="#data.RecordCount#">
     <cfset result[i][1]=data.state[i]>
     <cfset result[i][2]=data.state[i]>
</cfloop>
This will make your select look something like this in the rendered HTML:
<select id="states" name="whatever...">
     <option value="Alabama">Alabama</option>
     <option value="Alaska">Alaska</option>
</select>
So then, on your second, dependent select, you'd specify the binding like so (just like you did, really):
<cfselect name="waters" bind="cfc:_ffc_cfc_select_jump.get_waters({states})" bindonload="false"></cfselect>
However, now, because the value of the "states" select options are state names, rather than ids, you should now be able to use the argument in your query based on state names:

<cffunction name="get_waters" access="remote" returnType="array">
     <cfargument name="location" type="string" required="true" default="">
     
     <cfset var data="">
     <cfset var result=ArrayNew(2)>
     <cfset var i=0>
     
     <cfquery name="data" datasource="mydsn">
        SELECT id,name
        FROM waters
        WHERE bow_state = <cfqueryparam value="#arguments.location#" cfsqltype="varchar" /> 
     </cfquery>
     
     <cfloop index="i" from="1" to="#data.RecordCount#">
          <cfset result[i][1]=data.id[i]>
          <cfset result[i][2]=data.name[i]>
     </cfloop>
     
     <cfreturn result>
</cffunction>

Cffunction returntype question

I've got a function (below) in a CFC that executes a stored
procedure. The procedure has 2 input parameters and a single output
parameter. I want to cfoutput the value of the output parameter in
the procedure. The procedure does it's job in CF if I don't return
the output parameter. I keep having problems with the
returnvariable type. I've output returntypes of query in the past
without any problem, but never a single calculated value. The value
being output by the procedure is a long integer.

<cffunction name="myFunctTest" hint="ProcedureTest"
returntype="??????">
<cftry>
<cfstoredproc procedure="myProc" username='#this.user#'
password='#this.pass#' datasource='#this.dSource#'>
<cfprocparam type="Out" cfsqltype="cf_sql_integer"
variable="OutputID">
<cfprocparam type="In" cfsqltype="CF_SQL_INTEGER"
value='#this.par1#' dbvarname="myPar1">
<cfprocparam type="In" cfsqltype="CF_SQL_VARCHAR"
value='#this.par2#'dbvarname="myPar2">
</cfstoredproc>
<cfcatch type="any">
<cfreturn "Error in Function...">
</cfcatch>
</cftry>
<cfreturn ??????>
</cffunction>

<cfinvoke component="cfc.myCFC" method="myFunctTest"

<cfinvokeargument name="par1" value="#Form.MyPar1#">
<cfinvokeargument name="par2" value="#Form.MyPar2#">

Thanks in advance

Combine,
Are your stored procedure parameters defined in the same
order you are using them in your CFSTOREDPROC tag? Bear in mind
that the dbvarname attribute is ignored in CF6+.

What is it about CFFUNCTION that slows things down???

I have some code that imports the contents of an Excel
spreadsheet into my database, during the import process I also do a
fair amount of data massaging. When I run this code straight from a
URL it completes in about 90 seconds. When I encapsulate the exact
same code into a CFC function and call it from my Flex application
the run time jumps to around 10 minutes. Is there something about
calling a CFC function from within Flex that I am missing here? The
only differences in the code are a few passed in variables (which
are hard coded in the URL version) and the CFFunction tags. The
differences are trivial so I don't see how they could be accounting
for the extra time.
Any thoughts on why the CFC runs so much slower than the
CFM??? Oh... I am running CF 7.02 and my client will be on that
platform for the foreseeable future.

I think it is something to do with how the end of the
function processes. I am able to watch the records get wrote into
my database table. From the time the last record gets wrote to the
time the end of the function is processed is about 19 seconds for
500 records. That time goes up when more records are processed too.
Here is the code at the end of my loop that processes the data
prior to the end of the function. When the /CFLOOP is reached is
when the last record is wrote to the table.
<CFSILENT>

<CFTRANSACTION>
<cftry>
<CFLOOP QUERY="GetData">
<cftransaction action = "commit"/>
</CFLOOP>
<cfcatch type="database">
<cfthrow message="function = ADD records, MyFlag =
#MyFlag# #cfcatch.Message# #cfcatch.Detail#">
</cfcatch>
</cftry>
</CFTRANSACTION>

</CFSILENT>
<CFSET MyReturnString = GoodCnt & ',' & BadCnt1
& ',' & BadCnt2 & ',' & BadCnt3>
<CFRETURN MyReturnString>
</CFFUNCTION>
I have been playing with adding a CFTRANSACTION into the code
to see if that helps or hurts. So far it has not made a difference.
Bottom line is after the data is processed the function is not
returning to Flex in a timely manner.

Cffunction valitation error

Hi,
I have a form where I fill a customer-no. into an input field and get the customer name using databinding.
This works fine, but when I put non-numeric values into customer-no I get following error:
Error invoking CFC customer.cfc : The CUST_ID argument passed to the getcustomer function is not of type numeric. [Enable debugging by adding 'cfdebug' to your URL parameters to see more information]
The message is correct, but how can I avoid to run the getcustomer function when the value is not numeric?
Here is my code:
The form:
<cfinput type="text" name="customer_no" style="width:140;background-color:yellow" maxlength="10" validate="integer" validateat="onblur"   message="Customer No. format is integer">

That is a trick question! The attribute bind="cfc:customer.getcustomer({customer_no})" implies that the function will run automatically, whether or not customer_no is numeric.

Might not be an issue but, while your Team variable can be null, the cfargument tag types the variable as a numeric value (as opposed to any or whatever). Depending on what you're supplying this could be a source of the error.
As mentioned we would have to see the code. But that could well be the problem. There is really no concept of a "null" form field. If you are passing in the values of text fields, empy fields will be treated as an empty string "". Since an empty string is not numeric, it would cause exactly the error you are describing.

<cfset form.someField = "" />

Cffunction - Accepting and Returning PDFs in memory

Hello,
This is something that I should probably know by now in my CF career, but up until now I have never thought/had to do this type of thing.
I have defined a couple functions that I would like to handle accepting, manipulating, and returning PDFs in memory. What data types should I be using for accepting and returning the PDF in memory between functions? I would prefer to stay away from "any" if possible, but let me know if that is the only choice.

Advance Thanks

Adding the output="no" property to the the <cffunction...> tag so that ColdFusion does not include any whitespace from the function may help.
You may also want to consider some of ColdFusion's other whitespace management features. <cfsilent>...</cfsilent> <cfsetting enableCFoutputOnly="Yes"> being a couple of the most utilized.

CFFUNCTION not working

ColdFusion cannot determine how to process the tag

If you are using tags whose names begin with CF but are not
ColdFusion tags you should contact Allaire Support.

Hi,
Try doing it using <cfscript>
<cfscript>
function myFunction() {

I do not think you can do it that way in CF 5. Is it possible
for you to upgrade to at least ColdFusion MX? If so then your code
would work I presume.

CFFUNCTION question

I am trying to run a function like:
<cfoutput>#F_name#</cfoutput>
<CFFUNCTION NAME="F_name">
... generates some tables and reports ...
</cffunction>
Instead of the tables, I have a coded string of characters.
Am I missing something here ?
Should the function be in CF component ?
Thanks for help !

If your function generates output, then the below would work.
<cfoutput>#F_name()#</cfoutput>
But I'm guessing you're not generating output and just doing
calculations, you need to return the value using something like
<cffunction name="F_name">
<cfset a = 1>
<cfset b = 2>
<cfreturn a + b>
</cffunction>

CFFUNCTION returntype error

"The value returned from the addRequirement function is not
of type query" is what I get when I execute the below function.
This works fine in 7, but in 8 I get that error. Any ideas?
<CFFUNCTION NAME="addItem" output="false"
returntype="query">
<CFARGUMENT NAME="userid" TYPE="numeric"
REQUIRED="true">
<CFARGUMENT NAME="title" TYPE="string"
REQUIRED="true">
<cfset var addRequirement = "">
<CFQUERY NAME="addItem" datasource="#variables.dsn#">
INSERT INTO test(userID,title)
VALUES (#ARGUMENTS.userID#,'#arguments.title#')
</CFQUERY>
<cfreturn addItem>
</CFFUNCTION>

In addition to the insert not returning a result set, you
have your var declared as 'addRequirement'
but your query name and return value are 'addItem'
If it were me, I'd set the return type to boolean, then set a
var result = 'FALSE'. Wrap the insert query in a CFTRY and if it's
sucessful, set result = 'TRUE' and then return result

Cfreturn variable is not recognized when outputing content

I have a page that i wish to display total invoices paid to a particular contractor. This Page is Runnign CF9. I'm using a CFC page to write my queries and a action page to display the output via a search box from a search page. Whenever i input the invoice id, coldfusion throws the error: Variable RECENT_INVOICE is undefined" Am i missing something? my syntax is written below:

<cfcomponent>
<cffunction name="getinvoice" access="public" returntype="query">
<cfquery name="recent_invoice" datasource="w9">
SELECT invoice.*, project.*, bid.*, CONCAT(w9.w9fname,' ', w9.w9lname,' ', w9.w9businessname) AS Contractor, w9.*
FROM invoice, project, bid, w9
WHERE invid = #form.invid#
AND INVOICE.invcontractor = W9.w9ID
AND INVOICE.invproject = PROJECT.proID
AND INVOICE.invproject = BID.bidproject
AND INVOICE.invcontractor = BID.bidcontractor
</cfquery>
<cfreturn recent_invoice>
</cffunction>
</cfcomponent>

<cfinvoke
component="invoice.componets.test"
method="getinvoice"
returnvariable="recent_invoice">

</cfinvoke>

<cfoutput>#recent_invoice.invdate# - #recent_invoice.invjob1# - #recent_invoice.invamt1#</cfoutput>

Looks like you are referencing a form field in your query; form.invid. You are not submitting a form, you are calling a cfc so you probably want to add an argument to your function and pass the value when you call it. Change like so:

<cfcomponent>
<cffunction name="getinvoice" access="public" returntype="query">
<cfargument name="invid" type="numeric" required="true" />
<cfquery name="recent_invoice" datasource="w9">
SELECT invoice.*, project.*, bid.*, CONCAT(w9.w9fname,' ', w9.w9lname,' ', w9.w9businessname) AS Contractor, w9.*
FROM invoice, project, bid, w9
WHERE invid = <cfqueryparam cfsqltype="cf_sql_integer" value="#arguments.invid#" />
AND INVOICE.invcontractor = W9.w9ID
AND INVOICE.invproject = PROJECT.proID
AND INVOICE.invproject = BID.bidproject
AND INVOICE.invcontractor = BID.bidcontractor
</cfquery>
<cfreturn recent_invoice>
</cffunction>
</cfcomponent>

<cfinvoke
component="invoice.componets.test"
method="getinvoice"
invid="#yourInvoiceNumber#"

Why setting var in CFFUNCTION causes error

As far as my knowledge goes, the BEST practise when setting
local variable inside a CFFUNCTION is to use the word "var" in
front of the variable name, for example: <CFSET var
myVariable="whatever">
I'm doing it now and all I get is an error message saying:
Error invoking CFC name_of_cfc:local variable myVariable on
line 60 must be grouped at the top of the function body!
I'm using CF8 and I need to use cfswitch within the
cffunction, so when I do <cfcase value="SomeValue"><cfset
var myVariable="TheValue"></cfcase> etc I got that error.
When I tested with just CFSET var MyVariable="TheVariable"
with no cfswitch/cfcase I still get that error
when I took out the word "var" from cfset, I have no error, I
put these variables directly after my cfarguments. Does anyone know
why this is happening to me?
I thought if I don't use the "var" word for my variable set
within cffunction there will be possibilities when later on setting
up another variables outside this function and if the name happen
to be the same, will override each other and causing disaster to my
application.
Please help!!

Yes, this is the best practice to make the variable local to
the
function. But you only need to use the var keyword once when
you define
the variable. And you must define the local variables with
the var
keyword at the very beginning of the function body. The only
content
allowed before this happens are the argument definitions,
i.e. the
<cfargument ...> tags.
If you have a variable that you don't need to use, you just
need to
define it with a default and|or dummy value in the beginning
of the
function. Then you can set it's value appropriately later in
the
function when it is required. This is often done with query
tag return
variables.
I.E.
<cffunction name="myQryFunction"...>
<cfargument name="someArgument"...>
<cfset var localQry = "">
<cfquery name="localQry"...>
SQL
</cfquery>
<cfreturn localQery>
</cffunction>
Because of this necessity to define all local variables at
the beginning
of the function, a lot of developers use a standard where
they define a
local structure. They can then just append new keys and
values to this
local structure throughout the function. Personally I don't
see much
advantage to doing this, but to each his|her own.
I.E.
<cffunction name="myQryFunction"...>
<cfargument name="someArgument"...>
<cfset var local = structNew()>
<cfset local.something = "FooBar">
<cfreturn local.something>
</cffunction>

Cffunction & cfreturn
