Cold
Fusion Web Hosting Tips
Cold fusion is defined as “A
scripting language for web designers that wish to do advanced
development and/or
database interfacing. Cold fusion supports MS Access, dBASE,
FoxPro, and Paradox databases.” A more detailed definition
of cold fusion is, “An application development tool from Allaire
Corporation, MA, (www.allaire.com), for writing Web pages that
interact with databases. Instead of writing tedious CGI and
Perl scripts, operations are coded in the Cold Fusion Markup
Language (CFML) which uses HTML-like tags embedded in the Web
pages. The Cold Fusion Engine, which interfaces with a Windows-based
Web server, interprets the codes, accesses the database and
delivers the results as HTML pages for the Web browser.”
Cold
fusion webhosting is all about making use of content within
a specific time frame. Just as products in the grocery
store have a shelf life (and expiration date), so does content
that appears over the Internet. Cold fusion makes it possible
for you to design a time frame system that can work to your
advantage and your “timeline” for content. Cold fusion has
functions that make publishing as well as getting rid of information
as simple as can be. These include cold fusion’s Now ( ) function
as well as the CFIF tag and CreateDateTime ( ).
The CFIF tag is one of the most useful and also one of the
most popular tags used in cold fusion web hosting. It is made
use of in order to “hide or display content based on comparing
a set date to the time that the page is parsed for the visitor.”
On the other hand, the function of the CreateDateTime ( ) is
to take the boundaries of certain dates and times and then
create a cold fusion “date/time object.” There is a very specific
formula to how CreateDateTime looks- it goes like this (year,
month, day, hour, minute, second). So another words if it was
10:02 am on April 16, 2006 it would look like this in cold
fusion terms- (2006, 4, 16, 10, 02, 0). The Now ( ) component
of cold fusion also deals with dates and times but it has no
limitations put upon it. Now ( ) devises a cold fusion date/time
object for the date and time in question and it takes into
account time down to the very second.
The above elements of cold fusion are very helpful when it
comes to, for example setting a date in the future for a contest
to end. With these functions in place developers can set dates
on their websites for announcement, campaigns, events, etc.
ahead of schedule and won’t have to physically do it on a certain
date. You can have your content be near or far and can, on
your own timetable make it “appear or disappear” as you wish.
Another tip about cold fusion webhosting are the templates
that are used and these are cold fusion custom tags. Very similar
to other files in the CFML format, cold fusion custom tags
are specifically designed with the purpose of using them over
again. Custom tags save a tremendous amount of time for coders
especially if they are to be used often. As well free and/or
cheap custom tags can “add functionality” to the entire set
up. Cold fusion custom tags are broken down into two basic
categories- one makes use of the CFML code and the other includes
C + +, Java and/or other languages.
A simple custom tag (or CFML based tag) is put to use on a
page and then code is added to the selected template and there
are no inputs involved. In order to add a “custom tag’s functionality”
to your web page you will need to open up the custom tag directory
and include the custom tag in it. It is a good idea to make
sure that the custom tag is placed in the exact folder that
it was assigned to via the Cold Fusion Administration panel.
In order to create a simple custom tag it is necessary to
save a certain percentage of the code as a template of cold
fusion. Attributes that are used in designing a custom tag
make it imperative to “reference the attributes using the attributes
scope.” It is within CF_States is such that nonverbose and
selected (attributes.nonverbose and attributes. selected) are
used as references in the cold fusion custom tag.
