Attention folks,
the following patch is pre-pre-pre-beta ;-) But it should work well with
Smarty 2.5.0.
Here's what can be done with it:
Imagine you have a cached template but want some parts to never get cached.
In this case you needed to use an insert tag {insert type="foo"}. I don't
like this approach even if I know alot other people do ;-) It splits my
templates too much because I use alot of user-specific buttons and links.
After applying this patch the following is possible:
{* This is a cached template *}
This is cached: {$foo}
{nocache}This is not cached: {$foo}{/nocache}
This is cached again: {$bar}
It work's pretty well for me even if it's not that fast anymore because I am
using an eval() call :-( Perhaps this can be fixed in a later version... But
hey, it's faster than not using any caching at all.
For outputting the value of a single variable you can do
{nocache}{$foo}{/nocache} or even {$foo|nocache} which prevents $foo from
beeing cached too. You can even prevent a plugin function from beeing
cached: {foo|nocache bar="blah"}
Attention: You cannot use the nocache modifier with function parameters yet.
Things like {foo bar=$foo|nocache} won't work for now. I'll implement this
asap.
What I want to do now is to change the register_function to use an
additional parameter "cached". This way you could do something like
$smarty->register_function("foo", foo, false). That's because {nocache} tags
and modifiers gives too much possibilities to our designers. A designer
shouldn't need to care if a specific function needs to be cached or not.
It's better to let the developer decide, isn't it?
ATTENTION AGAIN: The following patch is not testet in a productive
environment. It works well for me but who knows if it works for you ;-)
What do you think? Any ideas?
Bye,
André
