I just improved my ColdFusion class website. I used more fileExists functions to automate the detection of the project files in the URL variables. Now I don’t have to worry about adding the projects to the cfswitch statement anymore. Here is the code snippet for one of my cfcase statements:

<cfcase value=”4″>
<cfif fileExists(filePath[4])>
<cfinclude template=”../projects/project4.cfm” />
<cfelse>
<div id=”noVal”>This project is not available yet!</div>
<cfinclude template=”index.cfm” />
</cfif>
</cfcase>

Noted that I used an array in the fileExists function. Here is the cfloop statement for the filePath array:

<cfloop from=”1″ to=”10″ index=”i”>
<cfset filePath[#i#] = ExpandPath(“projects/project#i#.cfm”)>
</cfloop>

As you can see, I used an array inside cfset statement to store 10 ExpandPath functions. This is my first time to use the array in a ColdFusion variable. In fact, I didn’t know anything about how to use ColdFusion array. I just applied the array based on the other programming languages that I have already known. According to course syllabus, we should learn ColdFusion array at later chapter.

At first, I used filePath#i# inside the loop to declare a regular ColdFusion variable. ColdFusion outputted an error stated that “ColdFusion was looking at the following text: #” . Then I tried the traditional method of adding an array by surrounding the loop variable with a pair of brackets. I was very surprised that it actually worked.

I applied the same technique to the title of each webpage so that I no longer forget about adding project title to the title.cfm when completed a project. Here is the code snippet for one of the cfcase statements:

<cfcase value=”7″><cfif fileExists(filePath[7])>#titleName[7]#<cfelse>#defaultTitle#</cfif></cfcase>

The defaultTitle variable is the default title on the site homepage.

The following are the additional updates for the site:

• Projects are now re-organized
• Project 1 has become homepage
• Project 2 has changed to project 1
• New project 2, Advanced SQL, was completed and added to the homepage
