[opencms-dev] Trying to include a file and have template applied

[Polizzi, Jim]

Matt,

It's OBVIOUS that you've been down this road before.  It's like you're reading my thoughts!

Yes - the reason that I was wanting to have a template applied is because I want to have differant "formats" of SideArea - or BodyArea, etc.  Possibly to allow with one "BodyArea" sub-template the ability to create a 2 column body - with a separate "page" for each column... The idea is to allow the content editor to be able to assemble various templates together and piece them together into a page.  Possibly with the following structure (for some page of the site - but a completely differant structure for another page of the site):

Main Template and page
	Two Part Body Area Template
		Content 1
		Content 2
	Multi-Part Side Area
		Nav Index
		Feature 1
		Feature 2

Has that been done?  Does that capability exist?  If so - where?

Also - Thanks for the tip on: "multiple content bodies option".  I'll research it.  This might be Exactly what I need for several things that I'm trying to do!

This would be a regular template, right. I mean, this is what a template 
usually does.

And again, this is pretty easy to do in the template. See if the file 
exists. If yes, then include it.

Now this is where I'm starting to get hazy. Why have a template defined 
for what equates to a snippet of code? Wouldn't you just put the 
"template" inside of the page template you spoke of above? I mean, if 
it's just a table, it would be better and faster to just use the main 
template to do the formatting.

The exception to this would be if you wanted to do many different 
formats for the SideArea file (e.g. 6 or 7 different complex table 
layouts depending on what info is inside the SideArea.html file). In 
that case, you would have to basically create a recursive template 
parser/processor, as others have already suggested.

>I can imagine several of these types of elements (SideArea / Feature Area / etc.)... that will be included in the page if they exist... the main point being that I want to provide Templates for each of these Page Sub-Elements - to simplify the work that the User (content editor) has to do to compose a rich page - that is consistant across the site.

I don't particularly see a problem with multiple additions. Your 
template may get bigger, but that is still preferable to implementing 
recursive template processing (for performance _and_ complexity reasons)

Again, I think this solution is the more complex way of solving the problem.

In the past, I've done the type of include that I'm explaining as a way 
of providing HTML ads, as well as dynamic or static content ("tip of the 
day" or extra bits of text). It works fairly well, and isn't hard to do.

Others have done something slightly different: they have enabled the 
multiple content bodies option and used the extra body fields to add the 
additional text. For more on that, you may want to search through the 
list archives or check out the forums.
