how to make a variable global to use in all of my cfm page?

Jan 15, 2012 11:33 AM

I have a problem with the variables.

i need to use a variable  " loginrecord" in all of my cfm pages, its created in my login.cfm and the value of this needed in other page and maybe i need to change it .

in ASP simply we can use SESSION to make a variable global , is there any way in coldfusion ?

 

also in ASP we have a command SESSION.SESSIONID ,  so return the unique number from browser and we can se it as a security check for each one of people login to our site and each one is seperate random and unique number , is there any similar in coldfusion ?

 

Thanks

Alireza

    You can also use session variables in ColdFusion.

    i set it in application.cfm

    <cfset request.loginsession=0>

    but when i change the value in other page, ( like index.cfm ) i can not retrive it in other page ( like clients.cfm )

    You just set a request variable, not a session variable.

     

    <cfset session.foo = "I am a session variable, and will be available on every page viewed by this user, or any program called by these pages, until the session expires">

    <cfset request.foo = "I am a request variable, and will be available in all programs called by this current page request.">

    <cfset application.foo = "I am an application variable, and will be available on every page within this application viewed by any user, or any program called by these pages, until the application expires">

    <cfset server.foo = "I am a server variable, and will be available on every page viewed by any user or any program called by these pages, anywhere on the server">

     

    I would strongly recommend you spend some time reading the documentation, which is very well written and all online.

    In addition to Dave's comments, if you are writing a new app, consider using Application.cfc instead of Application.cfm.  In the long run it will make things simpler.

    Thanks,

    the reason at the moment i stock with this command is i need to have login information available in all the pages to check the security. the good point i had in ASP is SESSION.SESSIONID   , it make a unique number base on browser and i can check it if user loged in or no , or if loged in is the same user or other user . i couldnt find same command in coldfusion , and now i use <cflogin> but if i can find the way to have a browser session it help me in other part of my program.

    i start coldfusion new ( near a month ) i have some book and Lynda DVDs, also online sources , and in this priod i re developed one of my program from ASP to coldfusion and its work. i am happy of this and help me to develop better and faster . in compare the coldfusion developed one realy is 40% original development in size and 50% faster . i have good background of ASP in last 8 years include MCSD and developed many program for a small and big companies. but i wanna to continue with coldfusion because i found it more helpfull than ASP specialy in FLASH development .

     

    BTW thanks for your help

    Session.loginrecord will make the variable available to all the CFM pages  visited during the session.

    ColdFusion has session.sessionID, too.
