George Whiffen,

a) Nested Loops
One problem that I see is that if I have nested loops:

<!-- BEGIN DYNAMIC BLOCK: loop1 -->
        <!-- BEGIN DYNAMIC BLOCK: loop2 -->
        <!-- END DYNAMIC BLOCK: loop2 -->
<!-- END DYNAMIC BLOCK: loop1 -->

I can assign values and get the predicted result, but if I try to use the
fastTemplate method clear_dynamic("loop2") I do not get the predicted
result.  The above situation is rather uncommon, and I work around it by
including HTML code into the php page, and assigning the result to a
fasttemplate variable.  This special consideration works fine for the few
pages that need the above nested loop, and the problem only appears if I
need to clear() a nested loop, which is another rare thing.  A good point
though, but relatively rare in my experience.  Even following my process for
handling nested loops in php using fasttemplate, it is likely less
complicated than attempting the same loop without fasttemplate.

b) Extra Luggage
Extra luggage, maybe, but would your prefer to stuff all your clothes into
one suitcase, or organize them nicely into two?  To further elaborate on the
analogy, it sure would be a lot easier to travel with companion using two
suitcases.  Using a templating system, like FastTemplate, saves countless
hours in a redesign, especially if all your doing is redesigning the HTML.
The designers I work with are on the extreme end of the print design world,
they need to see exactly what the page will look like.  The fasttemplate
{VARIABLES} have never been an issue.

c) Implications of php4 output buffering control
If you do not use CachedFastTemplate, then I would certainly look into using
the buffered output for caching.  Aside from cachinc, I have no further
experience with output buffering.

d) Dreaweaver library files/php includes
This indeed will remain an awkward arrangement.  Possible?  Yes, of course,
most things are, but awkward indeed.

e) Making variable place holders more useful to designers
This is a neat idea.  If end up setting up php up pages to process the page,
then echo variables, this sounds like a great idea.

If you need up update the html pages from command line or basic text editor,
you still can.  Dreamweaver's library items remain consist across all of the
applied pages, I just do a find on all open documents with EditPad, and the
site is updated the same way Dreamweaver would have updated the pages.

Subject: Re: [PHP] php includes === Dreamweaver library items


Your time and trouble in going through the issues are much appreciated, and
I'm starting to warm to the idea of FastTemplate.  It seems DYNAMIC BLOCK is
the answer
to the itty bitty little html file problem, but I'm still not entirely

a) Nested Loops
I notice the warnings about unpredictable results with nested DYNAMIC
Does that mean I can't have two levels of detail e.g. a list
of invoices and their detail lines (if any) on the same page?

b) Extra Luggage
I have a strong preference for using as few tools as possible.  This is why
I like php so much and why I don't like Perl.  With php 99% of the
is built-in to the the core and you don't have to worry about picking up
extra utilities.  I can't see the case for FastTemplate is overwhelming,
that php is ALREADY a templating language. Apart from an extra level of
indirection that allows for cleaner tags in the html, I can't see that it
that much. On the other hand it's clearly less powerful than "raw" php.

c) Implications of php4 output buffering control
I wonder if the new facilities for processing output buffers in php4 have
an impact on the best approach for templating.  Now that you have full
over the php output buffer, doesn't that reduce the importance of templating
systems such as FastTemplate whichpre-process output before it gets to
php's output buffer? I have the feeling that if you were/are designing
a templating system from scratch for php4, you could get a lot more
for less work now e.g. it would be easy to allow full embedding of php, by
carrying out the template parse after the first round of php processing
than before.

d) Dreaweaver library files/php includes
Having tried the .lbi/php include trick i.e. use Dreamweaver library files
as server includes, it does work, but not brilliantly.  Funnily enough, my
main problem was that Dreamweaver insists on library items consisting of
complete "blocks" so my header and footer each had to split in two to
draw out the side columns from the top and bottom sections.

e) Making variable place holders more useful to designers
The other unpleasantness I found with Dreamweaver is that "php" tags don't
so nice as variable names as the variable place holders.  However I think I
may have an even more attractive alternative than a cute variable name...
{STATE}         is informative when viewing via Dreamweaver/browser
<?= $state;>    just turns into a "PHP" placeholder
<?php //?>Washington<?php; print $state;?> appears as "Washington" in

This becomes even more attractive for text blocks e.g.
<?php /*?>
Washington is an absolutely great state
that we should all visit at least 5 times per year.
<?php*/; print $state_description;?>

The idea is that instead of a variable name the designer gets a practical
example of how the data may actually look, that simply disappears once it's
evaluated by php.

FINALLY, I really do agree with you that it would be nice to let Dreamweaver
do all the work on library items, but I don't want to get locked into always
depending on Dreamweaver to maintain the templates and their includes.  It's
much nicer in an emergency if I can just change the one include via any text
editing tool and know the site will still work properly.

Once again, thanks for some very interesting comments and advice,
