Boolean values can be a time trimmer when you're crunching 10 hours of code in a 5 hour deadline. IF statements can become quite burdensome at times, constantly typing out the conditional. With boolean values, you can shortcut that conditional typing slightly. Here is why.
<cfset flag = 1 /> <cfset results = "" /> <cfif flag eq 1> <cfset results = "foo" /> <cfelse> <cfset results = "bar" /> </cfif>
Pretty simple, right? No hidden functionality here. Let's take a "little off the top", barbershop-style, showing you how I do it.
Voila! Overall, it's not much, but with IF statements in bulk this can be a helluva little trick.
How does it work? Well, the value of flag is set to "1". In boolean terms, 1 means true/on, while 0 means false/off (Access DB users will notice this as well). Since an IF statement, at its base, merely checks one of two possible conditions for a variable, this works perfectly.
<cfif flag> literally processes to <cfif 1>, and since 1 means "true", that part of the IF statement is executed.
Coincidentally, this technique can be done if your variable is has a value of "TRUE" or "FALSE", as ColdFusion treats these two words in the same manner as 1/0. Now, back to your regularly scheduled program.
