RE: [PHP Template] load template from string var

I agree completely that this would be useful. I'm using my own home grown
template system right now that allows loading of the template via a variable
and I would say that this is a must.

Besides loading from a database one of the things that this allows is that I
can load a different template with the tmpl_fetch() of an already loaded
template. 

I have a loop that loads a list of templates out of a database and each pass
through the loop I call a specialized function that knows how to work with
each specific template. 

The first template in the loop is my generic template that pretty much every
page on the entire site uses. This template contains things like the main
site navigation, copyright footer, etc. Then the rest of the templates are
loaded for the features that are specific to a single page. The result of
each template is passed into the load of the next template. This way
template 2 can assign values to something in template 1, like the page
title.

Here is an example of what I mean:

1) Call the generic_function() passing the path of the generic_template.tpl
as a parameter.
The generic function does the tmpl_load() and tmpl_assign() for the
generic_template.tpl.

2) The generic_function() returns the parsed results of the
generic_template.tpl into a variable called $Holding

3) Call specific_function1() passing in the path of a specific_template1.tpl
and $Holding as parameters. specific_function1() does the tmpl_load() and
tmpl_assign() on _both_ the specific_template1.tpl and the $Holding
variable. The $Holding variable has tags for { PAGE_TITLE } and rather than
having generic_function() assign the page title, specific_function1() does
the assignment. There is a tag in the generic_template.tpl called {
MAIN_BODY } that is assigned the contents of specific_template1.tpl.

4) The specific_function1() returns the combined result of
generic_template.tpl and specific_template1.tpl into the $Holding variable,
replacing whatever it contained before.

This loop can go on and on loading as many templates as needed to build the
page.

Hope I explained this reasonably well. If not I can post some actual code.

My two cents,

Jonathan

Subject: [PHP Template] load template from string var


This may already be possible with the current API but I couldn't tell for
sure from the spec file, so here goes:

I just wanted to be sure that it's possible to load a template from the
contents of a PHP variable as well as from files.  This allows for the
possibility of storing templates in a database so that for example, I could
load $my_template from the database and then make it a template with
something like:

tmpl_load_from_var(resource tmpl, string varname)
    Loads a template from the contents of a string.

tmpl_load_from_var('my_template.tpl', $my_template);


So, is this possible by some other means currently defined in the spec?
