Functions
函数

Each Smarty tag either prints a variable or invokes some sort of function.
Functions are processed and displayed by enclosing the function and its attributes into delimiters like so: {funcname attr1="val" attr2="val"}.

smarty标签输出一个变量或者调用某种函数.
在定界符内 函数和其属性将被处理和输出.例如:
{funcname attr1="val" attr2="val"}.

Example 3-2. function syntax
例 3-2.函数语法

{config_load file="colors.conf"}

{include file="header.tpl"}

{if $name eq "Fred"}
	You are not allowed here
{else}
	Welcome, <font color="{#fontColor#}">{$name}!</font>
{/if}

{include file="footer.tpl"}

Both built-in functions and custom functions have the same syntax in the templates.
Built-in functions are the inner workings of Smarty, such as {if}, {section} and {strip}. They cannot be modified.
Custom functions are additional functions implemented via plugins. They can be modified to your liking, or you can add new ones. {html_options} and {html_select_date} are examples of custom functions.

在模板里无论是内建函数还是自定义函数都有相同的语法.
内建函数将在smarty内部工作,例如 {if}, {section} {strip}.他们不能被修改.
自定义函数通过插件机制起作用,它们是附加函数. 只要你喜欢,可以随意修改.你也可以自行添加.
例如 {html_options} and {html_select_date}
