[pLog-svn] Roadmap/performance

[Mark Wu]

Forgot {dynamic} tag, I will remove it from 1.1 I think..

I don't think we can solve {dynamic} problem easily, it is smarty's
limitation.

For example , you have two template file, a.template and b.template

a.template
=======
{assign var=xxx value=yyy}

b.template
=======
{include file="a.template"}
{dynamic}{$xxx}{/dynamic}

You know, what's the problem?

In the fisrt time you run this template, there will no error message, and
the template will show yyy ...

But, in second time you run this template, it will shows you the $xxx is
undefined, because a.template is cached ... 

The situation will happened in everywhere... :(

How to solve this?

According to smarty's forum (I discuss with them for 2 months ago, I think)
, there is no way to solve this, unless you make  make a  "smarty plugin"
and set the $xxx = yyy in this plugin  ...

It is too complicated for every situation.

That's' why I propose using "another way"

Maybe
1. Disable your cache (the easiest way)
2. PHP Cookie(then we use javascript to read cookie and add the content to
html page)
3. Ajax (through xmlhttprequest)
4. Ajax without xmlhttprequest
(http://www.phpit.net/article/ajax-php-without-xmlhttprequest/)

And, AJAX is not MAGIC, it is an old technology but with new application.
