If I set the return value to another variable, I get the output I expect. This is what I get when I run the code below. Anyone know why this is? I can find any documentation on this affect.<br /><br />Some text here: THE TEST STRING<br />THE TEST STRING<br />Some text here:THE TEST STRING<br /><br /><cffunction name="myFunction" returntype="string"><br /> <cfargument name="myFunctionString" type="string" required="yes"><br /> <cfset whatItDoes = UCase(myFunctionString)><br /> <cfreturn whatItDoes><br /></cffunction><br /><br /><cfset temp = myFunction('the test string')><br /><br /><cfoutput><br />Some text here:#myFunction('the test string')#<br><br />#myFunction('the test string')#<br><br />Some text here:#temp#<br><br /></cfoutput> January26 0 0 2005-02-14T11:13:33 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#21681 To return a component from cffunction, use the dot notation "folder.folder.cfcname". btw, slash "/" doesn't work here.<br /><br /><cfcomponent><br /><cffunction name="myMethod" returntype="myVersion.myPackage.myComponent" access="public"><br /> <cfset result = CreateObject("component", "myVersion.myPackage.myComponent")><br /> <cfreturn result><br /></cffunction><br /></cfcomponent> awetiaue 0 0 2004-09-23T15:50:56 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#19712 I needed to know if we could pass more than 1 arguments and return long strings...wondered for a while, tried to search for examples for a while and then decided to give it a shot. Here is a function I used to populate a <select> menu:<br /><br />in the main program sequence, here is how I call the function:<br /><br /><cfoutput>#createoption("yan","Yankton")#</cfoutput><br /><br />in the function, I compare a form element called stationz with "yan" (or any other short form for a station). If they are equal, I return an <option> tag with "selected" property otherwise I simply return the <option> tag.<br /><br />Here goes the function:<br /><br /><cffunction name="createoption" returntype="string"><br /> <cfargument name="whatstation" type="string"><br /> <cfargument name="propercasewhatstation"> <br /> <br /> <cfif #stationz# eq #whatstation#><br /> <cfreturn "<option value='#whatstation#' selected>#propercasewhatstation#</option>"><br /> <cfelse><br /> <cfreturn "<option value='#whatstation#'>#propercasewhatstation#</option>"><br /> </cfif><br /></cffunction><br /><br />This helped me reduce coding of 19 stations and it is going to help me for 180 more stations. I hope someone can get the idea from here and modify it to their own use.<br /><br />Chirag Shukla. zedfox 0 0 2004-08-06T20:52:00 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#15963 The void entry was incorrectly removed from the list of cffunction returnType attribute values. <br>You can use void as a returnType attribute value for all cffunction tags except for those where the access attribute is remote. <br>A function that is accessed remotely, such as by a web service, must return a value; otherwise, attempts to use the function remotely will cause errors. halL 1 1 2004-06-02T13:33:39 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#14930 The question about "void" return type still have no answer... I'm interested too: it's supported or not? It's deprecated? If I use it could I run into problems with newer versions of CF?<br /><br />I miss the "history" part of this tag too, like in "cfinvokeargument", for example, we read: "ColdFusion MX: Added this tag." Several tags in the documentation doesn't have this history information (like cfargument, cfcomponent, etc). You could review it. fstrevisan 0 0 2004-05-17T13:02:16 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#10099 I think the information you want is available from this link: http://www.macromedia.com/support/coldfusion/ts/documents/cfmlhistory.htm jrunrandy 1 0 2004-03-08T05:47:22 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#10019 Does this tag available in ColdFusion 5, I am sure not after spending 4 to 5 hours.<br /><br />Along with the tag documentation Cold Fusion provides the versions as well on which these tag works! 0 0 2004-03-07T10:23:54 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#5564 Got a problem with understanding returnType = a component name although I am not new to CF. Never seen it used (or didn't noticed). Could someone post an example of when to use it and how to use it? michalg 0 0 2004-01-20T09:20:26 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#5048 I use void all the time w/o a hitch Dross.2 0 0 2004-01-09T08:20:28 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#4602 Is returnType="void" still valid and supported? The MX doc includes it, but the MX 6.1 doc here does not (see MX doc page http://livedocs.macromedia.com/coldfusion/6/CFML_Reference/Tags-pt145.htm#2852457 ) cfdevel 0 0 2003-12-16T11:10:55 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#4452 Allen's comment has to do with the wording of the error message. jrunrandy 1 0 2003-12-11T11:15:08 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#4450 Why is that a bug? It should be a wanted feature to have the type Integer but Allen should use type Numeric until then. 0 0 2003-12-11T11:03:51 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#3904 This has been entered as bug 53756. jrunrandy 1 0 2003-11-18T08:44:47 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/tags-p43.htm#3902 Hey guys. Love the livedocs.<br /><br />CFFunction gave me a confusing error when I tried to pass in a return type of integer: <br /><br /><cffunction name="AddCustomer" access="public" returntype="integer"><br /><br />it should say that 'integer' isn't a valid return type rather than the return type isn't of type integer.<br /><br />HTH,<br />Take Care,<br />Allen Manning, Prismix Ltd.
