How would I convert the following Java code into DTML? This is just an example, I don't understand how methods are used in DTML.
String getFirstName(String name) { String lastName = name.substring(0, name.indexOf(' ')); return (lastName); }
I would like to see a DTML method which does this, how it is called and how the result is used in the calling method. Thanks.
This sounds like more of a task for Python than DTML. Snippets of Python can be pretty easily embedded in DTML documents. Off the cuff (i.e. UNTESTED CODE FOLLOWS), here's how I'd do it: <dtml-var "name[:_.string.find(' ', name)]"> The Python above essentially mimics the behavior of your Java method. It returns a substring (or "slice", in Python) of "name" from the beginning of the string to the first occurrence of a space. If you know a thing or two about Python slices, this should probably make sense. If you don't, there's copious documentation at http://www.python.org (or just email me privately and I'll try to help). That half-line above is all you need, presuming "name" is defined somewhere in your namespace (e.g. as a document property or a variable passed from an HTML form). No DTML methods are necessary, as you can see, though you could almost as easily stick that line into a separate DTML method and insert it with: <dtml-var dtml-method-name> But I don't know why you'd want to do that. Instead, you probably want to include any part of the document which needs to use the first name in a dtml-let tag: <dtml-let first_name="name[:_.string.find(' ', name)]"> Hi there, <dtml-var first_name>! </dtml-let> Hope this helps.
