14 Developing Web Applications with ColdFusion

Adding More Variables to the Application

Applications can use many different variables. For example, the calldept.cfm

application page can set and display values for department, city, and salary.

To modify the application:

1. Return to the file calldept.cfm in ColdFusion Studio,

2. Modify the code so that it appears as follows:

<HTML>

<HEAD>

<TITLE>Call Department</TITLE>

</HEAD>

<BODY>

<STRONG>Call Department</STRONG>

4

4 <CFSET City="Boston">

4 <CFSET Salary="110000"

4

4 I’d like to talk to someone in #Department# in #city# who earns at

least #Salary#.

</CFOUTPUT>

</BODY>

</HTML>

3. Save the file.

4. View the page in your Web browser by entering the following URL:

http://127.0.0.1/myapps/calldept.cfm

Development Considerations

The same development rules that apply for any programming environment apply to

ColdFusion. You should also follow the same programming conventions that you

would with any other language:

• Comment your code as you go.

HTML comments use this syntax:

CFML comments add an extra dash:

• File names should be all one word, begin with a letter and can contain only

letters, numbers and the underscore.

• File names should not contain special characters.
