Scope of variables: Application.cfm vs Application.cfc - very confusing

• Application.cfm to Application.cfc: UNDEFINED Variables?

  I have an application that has been created in CF8... the previous programmer used Application.cfm. I prefer to use Application.cfc... so, I migrated the code to a .cfc... However, none of the variables seem to be defined. I placed the SystemFramework of onSessionStart, onRequestStart, rename the application whenever I change... I am constantly is UNDEFINED for my variables.

  Can someone tell me why this is?

  Second, for global variables such as serverRoot, secureServer, insecureServer, I guess that is the best place for these VARS SystemFramework... but for application objects, status, etc., it would be preferable to have these elsewhere? What is the harm in having all my variables global application within the SystemFramework?... .assuming they never defined. :/

  You are out of the method before anything can run. Remove the cfreturn or move it to the end of the function. Other than the lack of a few citations (maybe a problem of forum), it works fine.

  
           
  This will allow us to call any function object without instantiating
  APPLICATION.user = createObject ("component", "apps.com.User");

  These application variables must be declared in SystemFramework too. Otherwise, you re-create the shared components whenever a new user session starts.

• Question from newb on Application.cfc vs .cfm

  Sorry for the newb question total which is probably covered a bazillion times, but I have some difficulty to get things to work.  I know this, because I got the CF9 advanced training, but when you have 60,000 pages worth of content back to the office waiting to be converted into a new design, there is not much time to practice what you have learned in class .

  A lot of my Office Web site is rest when we were running CF 6.1, so what use the Application.cfm files.  Now that we have run CF8 (and could soon move to something even more recently), I would get everything upgraded, including obtaining my Application.cfm stuff in an Application.cfc file.  One of the reasons why I want to do this is because I have a few apps I want to use the OnRequestStart() methods for.

  My problem comes from the fact that our Application.cfm file done many things such as global variables, queries, and other things that I can't get to work within an Application.cfc file.  Particularly strange is the fact that I've recently implemented a CF10 site to the Web sites of the company of my wife and got done Application.cfc work without much trouble, leading me to suspect a problem installing with my office.

  I tried following the guide on the Hostek forum, but nothing helped.  I can't include the content of our old Application.cfm file in the new cfc.

  Any tips?

• The THIS Application.cfc and ranges of VARIABLES

  Traditionally this field stores the variables that are used outside the element and stores VARIABLES, well, variable, which are private to the component, right?

  I ask, because in my application.cfc BIFs (like onApplicationStart(), onRequestStart(), etc.), make calls to other components, and there are some values that are initially stored in the application.cfc that must be shared with these components (but I was told that I shouldn't do just these components inherit from the application.cfc)

  What I * WS * this has been calling these methods of a component and passing variables I * WAS * storing in the VARIABLES field as follows:

  <cfset componentObject.methodName(
       firstArg = VARIABLES.var1,
       secondArg = VARIABLES.var2
  ) />
  

  Thing, is that I found, these variables are often needed by a large number of functions throughout the application.cfc.  Should I be storing these values in the PRESENT application domain instead?  Someone told me she is sloppy to send simply all of THIS / VARIABLES of structure as an argument that is not yet defined in the function being called.

  I chose the scope of variables as this scope allows applications using my cfc to change the values of variables in their object.  I have rarely, if ever see a necessity to enable this.

  I suggest the way the values as arguments because my main use of the EFA is to produce reusable code.  In our configuration, (intranet with reusable code available for all applications), it is not sensible for a cfc directly using cfc another variables.  It might work, but it just seems wrong to me.

• Frequency of triggered application.cfc/cfm

  Hello, all,.

  You know... in all the years I've been coding in CFML, he never once came to ask me the question, but here it is...

  If I have a page as such:

  <!DOCTYPE html>
  <html>
    <head><title>Unknown Comic</title></head>
    <cfinclude url="menu.cfm"/>
    blah blah blah - foo bar
    <cfinclude url="footer.cfm" />
  </html>
  

  Does the trigger application.cfc only once (for the document itself)?  Or it triggers once for the document, and then once for each (total of three times for example above) include?

  V/r,

  ^_^

  (Forgive the n00b question - it just never came to mind so far).

  URL of attribute side, traction cfincludes 'in' the existing .cfm page content, so appropriate Application.cfc methods would be called only once.  It is always considered as a single application.

• Difference between Application .cfc and .cfm?

  Title says it all. I'm a little confused about the difference between Application.cfc and .cfm.
  
  I understand a little more about the .cfc, where you define the onRequestStart methods, etc.
  Yet, in one example, that I am following, they use .cfm and the tag < cfapplication >. The two seem to have called, but should I only use a single file? Or?
  
  Also, since both can be used what is the order by ColdFusion or is ignored if either is present?

  application. CFC gives you more control when the code is running. In an application.cfm file, all code in this file is processed at the beginning of each page request. With application.cfc you can assign code snippets to the appropriate method.

  Hi, im using flash remoting to call CFCS and I want to use the application.cfc to determine the environment (the APPLICATION.environment defines a DSN that is used in flash to CFC calls).

  I think you should read the operation expanded in the CF.  Read this entire section of the documentation:

  I can't guess where in your code you put the CFDUMP, so I can't really comment on the rest.

• Application.CFC and the directory mapping

  Hello

  We have a request that we would like to migrate to use Application.cfm to Application.cfc. It is a management application that is implemented on various websites (hosting us) with an "app directory" which is defined as a virtual site directory, with a few variables specific to the site (mostly just a couple of unique customer ID) located in an XML file at the root of each site definition offshore. In other words:

  www.site1.com is customer web app and /configfolder/appvars.xml

  www.site2.org is the same web application for client B and /configfolder/appvars.xml

  The actual application is a virtual directory, say:

  www.site1.com/Mgmt/

  www.site2.org/Mgmt/

  The /mgmt/ folder contains all the real application code - the only thing the root directories do is to hold the handle of the client-specific variables.

  "Historically, what we have done is to have an Application.cfm file in the app folder make a /mgmt/ < cfinclude template ="... / Application.cfm "> so that the same code runs for all sites, but tire of the credentials of the unique site of the folder parent site." But Application.cfm is a bit long in the tooth.

  The problem is that the server does not appear to 'find' the Application.cfc in the parent folder and I'm not sure, there is an equivalent ' cfinclude the file of a directory to the high "(sauf si vous pouvez cfinclude un CFC, dont je ne pense pas que vous pouvez le faire?)."extends"won't be not cut either because we would define a mapping to the top and know what specific Application.cfc" , we will expand when the only thing we know is that the data that we want to be in / configfolder /.

  The only solution I can think of is to use a single Application.cfc and put it in / mgmt /, transfer our customer-specific variables in the XML file, that we read in via cffile to a CF page that can be included in the Application.cfc (if we do not need to know the absolute directory name, as we do now) and then put things like Application.name dynamically , but I do not know if this is kosher. I would have preferred that each site has its own Application.cfc (perhaps by dint of him being a virtual directory?), but when you go to connect to www.site1.com/mgmt/, it does not use www.site1.com/Application.cfc. I have other traditional sites where Application.cfc 'filter' to subdirectories, but there it is in the root folder, you log in to the root folder, and when you navigate to a subdirectory, CF seems to be aware that you are always in the same application.

  I apologize if I did not explain this well and I'm pleased to say whatever it is - would appreciate advice on how to better implement Application.cfc in a scenario of multiple-sites-on-a-codebase.

  Ah, if it's a virtual folder you will have problems. The ApplicationProxy is "the way" it's done, but (as you guessed it) CF looks at the file level and is not aware of any IIS mappings.

  One reason they cannot not just in physical directories? Even using something as a junction of Windows is that they are physically located in a different place?

• CF 9: FC ajax is not compatible with Application.cfc?

  Hello

  Background:
  I use the Application.cfc framework.  I like the onMissingTemplate, onError, and other features that it offers.  I worked with Application.cfc since CF 7.

  I started working on a project that required of CF 9.  I wanted to use a control controls cfgrid and also some of the features of ajax for a form.  I met problems with cfgrid controls immediately.  The problem was with the attribute of link calling a remote function in a CFC.  Here is a sample of the error message that I am able to get help from? cfdebug = 1 parameter to URL:

  JSON parsing failure: expected ' "' character 2: '&' in {& quot;}" page & quot; : 1, & quot; pageSize & quot; : 10 & quot; sortColumn & quot; : & quot; & quot; & quot; SLEEP tDirection & quot; : & quot; CSA & quot ;}

  Notice that all of the characters in double quotes are somehow be transposed to be html encoded values '& quot;'.  That's what the JSON parser complains.

  I went from the tasks and began working on a simple form that uses an autosuggest feature.  While I started to test the form, I found almost the same exact error:

  JSON parsing failure: expected ' "' character 2: '&' in {& quot;}" vcSuggestValue & quot; : & quot; 5 & quot ;}

  After you change the settings without success, I decided to rename all the files in my Application.cfc and create a Basic Application.cfm file.  It worked!

  Then, I tried to find out what was broken in my file Application.cfc I thought that, maybe, I got something screwed up.  I found myself in a file like this:

  
  < cfproperty >
  < cfset myIdName = "abc_admin" >
  < cfset variables.dsn = 'abc' >

  < name cffunction output = "onRequestStart" = "true" returntype = "boolean" index = "Runs at the start of a query" >
  < name cfargument = "TargetPage" type = "string" required = "Yes" hint = "Path of the web root to the requested page." / >

  
  < cfset request.dsn = variables.dsn >
  < cfset request.vcProductName = "abc.org" >

  
  < cfreturn true / >
  < / cffunction >
  < / cfproperty >

  As you can see the file Application.cfc preceding has almost nothing in it apart from a few names and a data source definition.  Controls the cfgrid and autosuggest < cfinput > tag are still not working.

  I took my project and moved to CF 8 server where these features worked well.

  I tried to use Application.cfc on a CF 9 server running on IIS 6 and IIS 7.5.  Two of them are failing, so I do not think it is caused by the web server.

  At this point, I am inclined to think that Application.cfc features CF ajax is broken for ColdFusion 9.  If you have a solution to this problem, please reply to this message with a response.  If you have ColdFusion 9, please try a simple autosuggest field on a form and see if it works with a website of Basic Application.cfc, please reply with your results.

  Best regards

  You probably need to add an onCfcRequest() Manager to your Application.cfc file...

• How you include the doctype in Application.cfc?

  I am trying to convert an Application.cfm-Application.cfc file and in the cfm file, I got the following:

  <! - set the content type to ISO-8859-1, otherwise the default is UTF - 8->
  < cfcontent type = text/html"; charset = ISO-8859-1 ">"

  <! - set the doctype for all documents - >
  < ! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict / / IN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" > ""
  " < html xmlns =" http://www.w3.org/1999/xhtml ">

  I think I put the cfcontent in the SystemFramework function as well as other application variables.  No matter what I do, nothing happens the doctype to appear on the pages. Where do you put that in the SWC file?

  Thank you!

  If you want the OUTPUT of the OnRequestStart function, you must use OnRequest() and include the generated output.

  Really, which means you could probably do all what you want just in the OnRequest method, but which belongs to you.

  It is not that OnRequest() breaks webservices, ajax called ect.  OnRequest runs for ALL applications before the Web service request, ajax calls ect.

  Then, if anything method OnRequest adds content, such as the content of your topic, all applications, including Web services and ajax calls.  99.9% of the time, which added content will break the format and avoid thus the functionality of these web service and ajax requests.

  It is not hard to get around.

  (1) have a smarter onRequest method which includes when he meets the demands of ajax or Web service and not to provide content that will break.

  (2) make your resource webservice and ajax inside a different directory with another Application.cfc file with a different (or no) onRequest method.

  (3) as Adam said, don't put content in your Application.cfc but use any number of other methods to apply this type of standard output to all views.

• Tracking users in the Application.cfc, please help

  Hello;
  I wrote a small system for my website. I am trying the upfrade he works in CF 8. Here's what I do.
  
  I got this code on my site index.cfm page. I'm trying to move it to the Application.cfc file. When I do, it fits into the DB whenever the user hits a page or click on a link. I don't want to do this. I don't want that he tell me when they hit the site, and if I can what page they came in.
  
  Here is my code:
  < cfquery name = "tracking" datasource = "my - DB" dbtype = "ODBC" >
  INSERT INTO followed (HTTP_USER_AGENT, TRACK_DATE, REMOTE_ADDR, PageID)
  VALUES (' #REMOTE_ADDR #', ' #HTTP_USER_AGENT #', #CreateOdbcDateTime (now ()) #)
  < / cfquery >
  
  My pageID is go wherever I want information about what the user came on the page.
  I placed the query inside a function of session code, but it does not work at all right now, I need to limit the shots counted by the Application.cfm, if I place it within the area of application which is for global variables, it adds information to the DB every time, they click on a link, and I don't want that. With respect to the entry of the user page, I'm doing so that if someone enters the site leaves the floor on the about.cfm page, which is added to the db and so on. Is this possible? If so how would I do that?
  
  Here is my code so far application.cfc:
  
  < cfproperty output = "false" >
  < cfset myIdName = 'my web' >
  < cfset this.sessionManagement = "yes" >
  < cfset this.clientManagement = true >

  OK, I did a dump of the CF to the cgi on the server.
  

  He came back with all the cgi can be used on the server, it looks like I want to use cgi's PATH_INFO
  When I put it there, I get an error using this code: can I use this code instead? y at - it a big difference?

  Thank you.

• What executed Application.cfc?

  I'm working on a clients system that has a library of CFC in a folder called/Admin/cfcs.   Inside this folder is an Application.cfc file.

  There is also an Application.cfc file in the root directory.  Other folders as well as in the Admin folder are out of the root directory.

  When I run the model /Members/Index.cfm executed some of the methods of the SWC library.

  If they are not all calls to the library of CFCS that I'm 100% sure the Application.cfc in the root folder is run when I run one of the templates in any folder on the root folder.

  My question is that if a pattern such as/Members/Index.cfm, calls a method of the CFC library is the Application.cfc model in the folder/Admin/cfcs executed or is the root Application.cfc that executed.

  I think it's just the one root, but I'm not 100% sure.

  Any thoughts?  Have an Application.cfc in the library folder causes problems?

  Thanks in advance for the help!

  Your assumption is correct.  The application.cfc in/Admin/cfc is not running at all, unless there is a .cfm file that is somehow used.  The CF Server first searches the document .cfm file current application.cfc/cfm; If he does not, she keeps looking for records lower and lower until he finds an application.cfc/cfm and runs it recursively.  CFCS in a file with an application.cfc/cfm does not run another application.cfc/cfm; they rely on one that was already executed before loading the requested .cfm file.

  HTH,

  ^_^

• What is the problem with my Application.cfc file

  What have I done wrong?

  It comes in two models that you include in your function onRequest()?  They give really any content?

  You don't have the requested page being included.  You must add an argument to the upper part of the function to receive the requested page:

  Then you must add another to include this page:

  You will have to figure out if this includes should come before or after your existing includes.

  Yes, you must implement the cflogin code in your Application.cfc OnRequestStart method so that it works on all applications.
