I'm very glad with using phptal:cache, especially with "per " parameter.
But now, I want to achieve something like that:
I have following template:
<div id="word" phptal:cache="1h per url">
Word of the day is: <span tal:content="word">word of the
day</span>
</div>
Now I do:
{{
// :my php code: to retrieve word which takes very long to execute
// returns $word
$tpl=new PHPTAL('test.html');
$tpl->word = $word;
}}
I'd like to execute {{...}} only when cache is not fetched, else just
display cached HTML.
IMHO the best solution is:
$tpl=new PHPTAL('test.html');
$tpl->word = new WordGetter();
Word of the day is: <span tal:content="word/getWord"/>
Pass to the template an object that is cheap to create and have it do
heavy work only on demand, e.g. when $word->getWord() is called. If the
template is cached, the method won't be called.
An even simpler version of the same is:
<span tal:content="php:word_of_the_day()"/>
