How can I write the equivalent for
<cfset lang = Evaluate("SERVER.Locale.#LocaleName#.#SESSION.Locale#")>
without using Evaluate.
I tried something like
<cfset lang = SERVER[Locale][#LocaleName#][#SESSION.Locale#]>
after referring this, but it was not working.
UPDATE
<cfset localename = "test">
<cfset session.locale = "en">
<cfif Not IsDefined("SERVER.LOCALE")>
<cfset SERVER.Locale = StructNew()>
</cfif>
<cfif IsDefined("SERVER.Locale.#LocaleName#")>
<cfset StructDelete(SERVER.Locale, "#LocaleName#")>
</cfif>
<cfset "SERVER.Locale.#LocaleName#" = StructNew()>
<!---<cfset lang = Evaluate("SERVER.Locale.#LocaleName#.#SESSION.Locale#")>--->
<!---<cfset lang = SERVER["Locale.#LocaleName#.#SESSION.Locale#"]>--->
<cfset lang = SERVER.Locale[LocaleName][SESSION.Locale]>
<cfoutput>#lang#</cfoutput>
ERROR:
Element en is undefined in a CFML structure referenced as part of an expression.
This:
<cfset lang = Evaluate("SERVER.Locale.#LocaleName#.#SESSION.Locale#")>
Should be revised to this:
<cfset lang = SERVER.Locale[LocaleName][SESSION.Locale]>
You should not have the [Locale] in square brackets like that.
I think the error message (which you should always post with your question) probably actually explains that to you, dunnit?

I know this is fairly simple. But I can't find my cut paste code or something that works.
I am encrypting a string.
<cfset encrlink = encrypt("uid=WWWDDD&email=BOBEMAIL#BOB.COM", APPLICATION.AesKeyForMails, "AES", "HEX")>
Which works fine. And then I decrypt it.
<cfset dncrlink = decrypt("#encrlink#", APPLICATION.AesKeyForMails, "AES", "HEX")>
<cfoutput>[#dncrlink#]</cfoutput>
Which works fine. Gives out "uid=WWWDDD&email=BOBEMAIL#BOB.COM"
I need to get "uid=" and "email=" out and use as variables of the decrypted string. By parsing. I'm just a bit stuck. Is it Trim? Find? I kinda have this working. But not sure how to build the cfset.
<cfoutput>
<cfset theUrl = "#dncrlink#" />
<cfloop list="#theUrl#" index="URLPiece" delimiters="&">
<br>#listFirst(urlPiece, "=")# = #listLast(urlPiece, "=")# <br>
</cfloop>
</cfoutput>
I was able to do a CFIF for the Variables.
<cfloop list="#theUrl#" index="URLPiece" delimiters="&">
<br>#listFirst(urlPiece, "=")# = #listLast(urlPiece, "=")# <br>
<cfif #listFirst(urlPiece, "=")# is "uid"><cfset uid = "#listLast(urlPiece, "=")#"></cfif>
<cfif #listFirst(urlPiece, "=")# is "email"><cfset email = "#listLast(urlPiece, "=")#"></cfif>
</cfloop>
Too long for comments ...
You could also "genericize" the logic into something which could be used with any query string. Extract the parameters and store them in a structure
<cfset dncrlink = "uid=WWWDDD&email=BOBEMAIL#BOB.COM">
<cfset params = {}>
<cfloop list="#dncrlink#" index="elem" delimiters="&">
<cfset params[ elem.listFirst("=") ] = elem.listRest("=")>
</cfloop>
Then to access parameter values:
<cfoutput>
uid = #params.uid#<br>
email = #params.email#<br>
</cfoutput>
How do you track template path in ColdFusion?
I.E.
I have the following folder and file structure
index.cfm
<cfset ArrayAppend(request.Trace, '/')>
<cfdump var=#request.trace#>
foo
index.cfm
<cfset ArrayAppend(request.Trace, '/foo/')>
<cfinclude template='../'>
bar
index.cfm
ArrayAppend(request.Trace,'/foo/bar/')>
<cfinclude template='../'>
When I call foo/bar/index.cfm,
request.Trace equals:
'/foo/bar/'
'/foo/'
'/'
How could I do this without specifically declaring each folder name?
Have a look at:
expandPath(".")
getBaseTemplatePath()
getCurrentTemplatePath()
CGI.CF_TEMPLATE_PATH
CGI.PATH_TRANSLATED
CGI.SCRIPT_NAME
If you want the template stack trace, use this:
<cfset templateTrace = []>
<cfset tagTrace = createObject("java","java.lang.Exception").init().TagContext>
<cfloop array="#tagTrace#" index="tagInfo">
<cfset templateTrace.add(tagInfo.Template)>
</cfloop>
<cfdump var="#templateTrace#">
This will output all templates passed up to this call.
Not ideal but this worked for me.
<cfset currentFile = GetCurrentTemplatePath()>
<cfset currentDir = GetDirectoryFromPath(currentFile)>
<cfset webroot = expandPath("/")>
<cfset m_Trace = Replace(currentDir, webroot , '\')>
<cfset ArrayAppend (request.Trace, m_Trace )>
There is a new settings of Application.cfc in the coldfusion 10 which is:
this.smtpServersettings = as a structure
I can hard code the values here, but i am saving my mail settings in the database and i want to use those values here, is it possible or not to use the database settings here or not.
here is my Update:
<cfcomponent hint="File for the Website" output="false">
<cfsetting showdebugoutput="no">
<cfset this.name = "myProject1">
<cfset this.applicationTimeout = createTimeSpan(2,0,0,0)>
<cfset this.clientmanagement= "yes">
<cfset this.loginstorage = "session">
<cfset this.sessionmanagement = "yes">
<cfset this.sessiontimeout = CreateTimeSpan(0,0,40,0) />
<cfset this.setClientCookies = "yes">
<cfset this.scriptProtect = "all">
<cfset this.setDomainCookies = true>
<cfset this.customTagPaths = ExpandPath('customtags')>
<cfset this.datasource = {name="myDB"}>
<cfset this.smtpServersettings = {structur as username,password and mail settings}>
but that value needs to be through database, can you show me an example please
Yes, you should be able to set the value of the this.smtpServersettings variable from a database query. And for what it's worth, I think that setting as been available since ColdFusion 9.
All you would need to do is something like the following.
Run your query to get the values from the database
Create a new structure
Assign the three variables to that structure; server, username, and password
Assign the this.smtpServersettings variable to your new structure
Of course you will need to add some code to do something if/when your database query fails.
Update after the question was updated
Just do something like the following (pseudo code):
<cfcomponent hint="File for the Website" output="false">
<cfsetting showdebugoutput="no">
<cfset this.name = "myProject1">
<cfset this.applicationTimeout = createTimeSpan(2,0,0,0)>
<cfset this.clientmanagement= "yes">
<cfset this.loginstorage = "session">
<cfset this.sessionmanagement = "yes">
<cfset this.sessiontimeout = CreateTimeSpan(0,0,40,0) />
<cfset this.setClientCookies = "yes">
<cfset this.scriptProtect = "all">
<cfset this.setDomainCookies = true>
<cfset this.customTagPaths = ExpandPath('customtags')>
<cfset this.datasource = {name="myDB"}>
<!--- run your query here --->
<!--- check your query and do something appropriate if/when it fails --->
<cfset this.MyStructure = StructNew()>
<cfset this.MyStructure.server = this.MyQuery.ServerNameVariable>
<cfset this.MyStructure.username = this.MyQuery.UserNameVariable>
<cfset this.MyStructure.password = this.MyQuery.PasswordVariable>
<cfset this.smtpServersettings = this.MyStructure>
You also need to be aware that doing it this way will run that query on every page request. Make sure it runs fast.
I recently upgraded a system from CF8 to CF10 and have one bug that I'm having problems tracking down. It has to do with a remote API call that gets a JSON string back and that string then gets converted to a query object. That's where I'm coming across the error:
Element [n] is undefined in a Java object of type class coldfusion.runtime.Array. The problem is in the function that converts the string to a query.
<cffunction name="CFjsonToQuery" access="public" returntype="query" output="no">
<cfargument name="cfData" required="yes" type="struct"/>
<cfset var LOCAL = {}/>
<cfset LOCAL.tmpQry = QueryNew( ArrayToList(ARGUMENTS.cfData.Data.COLUMNS) ) />
<cfloop index = "i" from = "1" to = "#ArrayLen(ARGUMENTS.cfData.Data.DATA)#">
<cfset LOCAL.Row = QueryAddRow(LOCAL.tmpQry) />
<cfloop index="k" from="1" to="#ArrayLen(ARGUMENTS.cfData.Data.DATA[i])#">
<cfset LOCAL.colName = ARGUMENTS.cfData.Data.COLUMNS[K]/>
<cfset QuerySetCell(LOCAL.tmpQry,LOCAL.colName,ARGUMENTS.cfData.Data.DATA[i][k],LOCAL.Row)/>
</cfloop>
</cfloop>
<cfreturn LOCAL.tmpQry/>
</cffunction>
Anywhere the JSON returns 'null' (i.e. "...","19107-3609",null,null,null,"...") the error is thrown. I've tried using isNull to check if it's null in the cfloop:
<cfif isNull(ARGUMENTS.cfData.Data.DATA[i][k])>
<cfset ARGUMENTS.cfData.Data.DATA[i][k] = 'I AM NULL'/>
</cfif>
EDIT - here's a simplified example - the issue is the way the newer deserializeJson() works I believe:
<cfset jstr = '{"SUCCESS":true,"ERRORS":[],"DATA":{"COLUMNS":["ID","FNAME","LNAME"],"DATA":[[390132,"steve",null]]}}'/>
<cfset cfData = deserializeJson(jstr) />
<cfloop index = "i" from = "1" to = "#ArrayLen(cfData.Data.DATA)#">
<cfset Row = QueryAddRow(tmpQry) />
<cfloop index="k" from="1" to="#ArrayLen(cfData.Data.DATA[i])#">
<cfset colName = cfData.Data.COLUMNS[K]/>
<cfset QuerySetCell(tmpQry,colName,cfData.Data.DATA[i][k],Row)/>
</cfloop>
</cfloop>
I've tried all sorts of tests for empty string, isNull etc. and I'm still not sure how to get the query object built if deserializejson returns:
[undefined array element] Element 3 is undefined in a Java object of type class coldfusion.runtime.Array.
This does seem to work:
<cfset cfData = deserializeJson(returnData,'FALSE') />
<cfset qryData = cfData.data />
This lets me then use qryData as if it were a normal cfquery.
You can do a check if the element is undefined using the CF Function ArrayIsDefined(array, elementIndex)
What I've done for now is add 'FALSE' to the deserializeJSON strictMapping flag and that seems to automatically create a query object? I'll admit though this is getting into the underpinnings of CF10 and I could be wrong on that. I'll update my code above for visual clarity.
I've just had a strange issue with a client's website, my live domain was using my development domains Application settings. I've not had this issue before, and removing cflock around the Application.dsn (amongst other settings) resolved the issue.
As mentioned I have a live site *www.* and development site *dev.*, my development site is in a subfolder of the live site /dev/ and has it's own Application.cfc.
My first question is, if I have variables in my Application scope in the dev folder will this overwrite the Application scope variables in the folder above? Will it consider it the same scope? If so, then this might explain what the issue and if not then I am stumped.
My second question is, how should I correct cflock application scope variables in my application.cfc? Should I be doing this at all?
Here is my Application.cfc, advice would be greatly appreciated:

Why do you change your application name based on the environment it's in? That makes no sense. The application is still the same app, irrespective of whether it's in prod, or you're staging it, or developing it.
Equally, same with the source code. You've got your dev site within your live website? How does this make any sense?
I dunno what's going on with your application variables, but they're bound to the application name (this.name), not where the Application.cfc is in the directory structure.
I suspect your zero applicationTimeout is not helping matters much here. This basically means your application never actually persists... it'll be timing out every request. This makes no sense either.
You do not need to <cflock> that code in onApplicationStart(). ColdFusion will only allow one request to run onApplicationStart(): all other requests will be queued until it's completed, by which time the application has started, so the queued requests won't even attempt to run it.
I think your problem is most likely causes by your poor application framework design, and this weird thing you're doing having dev and prod in the same source code tree (which defies all logic).
Sort your source code out, and the problem won't arise.
You can use conditional logic to set your application name.
if ( YouAreHappy and YouKnowIt ) {
This.name = "ClapYourHands";
}
else {
This.name = "StompYourFeet";
}
In real life, your if condition would be something that differented the live and test environments. cgi.http_host is a good candidate.
