Вопрос
I have a site with a fairly complex structure of Smarty templates. For this question, suppose I have an outer template which includes (with {include}) one or more inner templates that are optionally included, depending on the data being displayed:

RussianOuter Template (with <html>, <head>, and <body> tags)
- Inner Template A (various content)
- Inner Template B (more content)
Sometimes, one of these inner templates needs to reference additional CSS files. I would prefer to have these within my <head> tag, for efficiency and to avoid FOUC. Is it possible to set some variable from Inner Template A that adds the appropriate <link> tag to <head> within Outer Template?
I was able to find someone who created a module to do something similar, but I don't know how I would set the necessary variables from the template to make it work in my case. I am using Smarty 3.

I had a similar issue some time ago. My solution is maybe dirty but maybe it could help you.
$css = '<link rel="stylesheet" type="text/css" href="/css/file.css">';
$smarty->registerFilter('output',create_function('$output','return preg_replace(\'/(<\/head>)/i\',\''.$css.'$1\',$output,1);'));
If you wrap this in a function, you can simply add css to your head section from everywhere.

Idea 1:
Wrap the same logic around the style sheet in your head that you use for displaying template A or B.
Idea 2:
Template 1 (Top Level):
<link rel="stylesheet" type="text/css" href="whatevs1">
{block name="childStyles"}
{/block}
Template 2 (Child Template):
{block name="childStyles"}
<link rel="stylesheet" type="text/css" href="whatevs2">
{/block}
A side note:
I understand the want to be W3 compliant using includes for stylesheets in HEAD but including them within the body wont break your html, even in IE7...
I encountered a similar obstacle a few years ago. Since smarty templates are almost all the time filled with php code, my solution is just declaring a special variable/array for this purpose in php, then looping through the array in your head template / outer template.
Example:
$your_special_css = array('css1.css', 'css2.css');
Somewhere else in your code...
$your_special_css[] = 'css3.css';
...and then give it to the template:
$your_smarty_template->assign('your_css', $your_special_css);
Then your outer template would look like this:
<head>
...
{foreach $your_css as $css}
<link rel="stylesheet" type="text/css" href="/css/{$css}">
{/foreach}
...
</head>
Same works for jscript-files, too.
