Subject: A new replacement for CFPARAM tag, huzzah!!!!
Hi all,
I've built a new CF_Param custom tag to be used in the place of CFPARAM.
It does exactly the same thing, except you get to provide a "search list"
of
variable names. If one these variables exists, then its value will be used
instaed of the default.
Take a look on http://Bjork.net/taggallery/index.htm
This has solved a problem I am always encountering, when building Custom
Tags that expect certain request-scope variables to exist. Of course, over
the eons, my naming conventions have changed, so the Custom Tag never knows
exactly which request-scope variable is actually being used. No worries,
with CF_Param, you can give the tag a list of possible names.
I look forward to any comments,
Thanks very much,
Lee (Bjork) Borkman

ps., Here is the readme text, if you're interested:
<CF_PARAM
NAME="title"
SEARCHLIST="request.title, request.page.title, request.app.title"
DEFAULT="RTA Web"
>
Syntax:
<CF_Param NAME="" SEARCHLIST="" DEFAULT="">
Description:
Replaces CFPARAM tag. Has the same effect as CFPARAM, except it searches
through a
list of variable names first. If one of these variables exists, then the
variable NAME
is set to that value.
Uses:
Great for reconciling inconsistent naming conventions, especially useful
for
request-scope
variables.
Example:
Say I am writing a Custom Tag to build a page header. The tag needs to
know
the width of
the page. That info is normally stored in #request.page.width#, but in old
applications
was stored in #request.pagewidth# and #request.width#.
A single call to CF_PARAM can set tyhe value of a new local "pagewidth"
variable:
<CF_PARAM
NAME="pagewidth"
SEARCHLIST="request.pagewidth, request.width, request.page.width"
DEFAULT="575"
>
If CF_Param finds that any of "request.pagewidth, request.width,
request.page.width" exist, then
that value will be copied into pagewidth (unless pagewidth already exists).
If none of these
variables exist, then the default of 575 will be used.
