Variable modifiers can be applied to variables, custom functions or strings. To
apply a modifier, specify the value followed by the |
(pipe) and the modifier name. A modifier may accept additional parameters
that affect its behavior. These parameters follow the modifer name and are
separated by : (colon).

$plugins_dir (also see:

Conventions) or can be registered explicitely (see: register_modifier). Additionally
all php-functions can be used as modifiers implicitely. (The
@count-example above actually uses php's
count-function and not a smarty-modifier). Using php-functions
as modifiers has two little pitfalls: First: Sometimes the order
of the function-parameters is not the desirable one
( {"%2.f"|sprintf:$float} actually works, but
asks for the more intuitive {For example:
$float|string_format:"%2.f"} that is provided by the
Smarty distribution). Second: with $security turned on all
php-functions that are to be used as modifiers have to be
declared trusted in the $security_settings['MODIFIER_FUNCS']-array.
capitalize
This is used to capitalize the first letter of all words in a variable.
将变量里的所有单词首字大写。
Example 5-2. capitalize
例 5-2.首字大写
index.php:
$smarty = new Smarty;
$smarty->assign('articleTitle', 'Police begin campaign to rundown jaywalkers.');
$smarty->display('index.tpl');
index.tpl:
{$articleTitle}
{$articleTitle|capitalize}
OUTPUT:
Police begin campaign to rundown jaywalkers.
Police Begin Campaign To Rundown Jaywalkers.
