CFIF/CFELSEIF/CFELSE

Used with CFELSE and CFELSEIF, CFIF lets you create simple and compound
conditional statements in CFML. The value in the CFIF tag can be any expression.
Syntax

Usage
Note that when testing for the return value of any function that returns a Boolean, you
do not need to explicitly define the TRUE condition. The following code uses IsArray as
an example:
<CFIF IsArray(myarray)>
When successful,
This method is preferred over explicitly defining the TRUE condition:
<CFIF IsArray(myarray) IS TRUE>
Note
<CFIF "11/23/1998 " GT "11/15/1998 ">
This switch is set on the ColdFusion Administrator Server Settings page. Please refer to

Example
<!--- This example shows the interaction of CFIF, CFELSE,
and CFELSEIF --->
...
<H3>CFIF Example</H3>
<P>CFIF gives us the ability to perform conditional logic
based on a condition or set of conditions.
<P>For example, we can output the list of Centers from the
snippets datasource by group and only display them <B>IF</B>
the city = San Diego.
<hr>
<!--- use CFIF to test a condition when outputting a query --->
<P>The following are centers in San Diego:
<CFOUTPUT QUERY="getCenters" >
<CFIF city is "San Diego">
<BR><B>Name/Address:</B>#Name#, #Address1#, #City#, #State#
<BR><B>Contact:</B> #Contact#<BR>
</CFIF>
evaluates to YES, the string equivalent of the Boolean TRUE.
IsArray
On UNIX, there is a switch that provides fast date-time parsing. If you
have enabled this switch, you must refer to dates in expressions in the
following order: month, day, and year. For example:
