DTML Basics (part 2) - Welcome To The Matrix
( Page 4 of 8 )

In addition to the "if" statement, DTML also offers the "if-else" construct, used to define a block of code that gets executed when the conditional expression in the "if" statement evaluates as false.

The "if-else" construct looks like this:

<dtml-if condition-is-true>

do this!

<dtml-else>

do this!

</dtml-if>

As you can see, this construct can be used to great effect in the last example - instead of two separate "if" statements, we can combine them into a single "if-else" statement.

<dtml-if expr="name == 'neo'">

Welcome to the Matrix, Neo. Access granted.

<dtml-else>

I wonder if you've heard of Shakespeare, <dtml-var name>.

<p>He postulated that a rose by any other name would smell just as

sweet.</p> <p>Unfortunately for you, I disagree. Access denied.</p>

</dtml-if>
