i can achieve that separation in phplib using blocks, i.e blocks of template
that may be repeatedly replaced, hierarchically if so desired. presumably
smarty has something equivalent. but, naturally, this doesn't meet your
"pull" requirement.
hoever, i sometimes find that some mixing is inevitable. for example, if i
am listing music recordings but not using a table, just a list. my template
might be (leaving out the classes and ids. and humor me in my old-fashioned
tag preferences):
<!-- BEGIN songblock -->
<li><b>{artist}</b>, {disk} <i>{label}</i></li>
<!-- END songblock -->
that works but if my database entry for a given disk has no information on
the label then the html output looks a but nasty:
<li><b>Mika Miko</b>, We Be Xuxa <i></i></li>
which sort of works but offends my sensibilities. since phplib doesn't have
a way to make a chunk of template conditional (other than with a block,
which would become a pita as you can imagine from the above), i sigh, shrug
and move the <i></i> in the conditional in the script. oh well. purity is
idealistic.
a possible solution would be to define macros in the template, maybe...
{MACRO:label=, <i>{label}</i>}
that would give me an optional comma and get rid of the space if there's no
label data while keeping all html out of the script.
while this achieves the ideal of separation i'm not sure it's really more
practical than the impurity of having some html bits in the script. having
practical experience with just one approach i can only speak theoretically
of the other.
(btw: macros can in fact be done in phplib templates by putting each macro
in a template file of its own, but that doesn't sound too practical in the
long run, does it?)
on another different topic, i would make independence of the output language
a requirement of the template scheme. e.g. besides html, i use phplib
templates to generate plain text emails, sql files, json ajax responses,
whatever...
