include

Attribute Name	Type	Required	Default	Description
file	string	Yes	n/a	The name of the template file to include
assign	string	No	n/a	The name of the variable that the output of include will be assigned to
[var ...]	[var type]	No	n/a	variable to pass local to template

属性	类型	是否必须	缺省值	描述
file	string	Yes	n/a	待包含的模板文件名
assign	string	No	n/a	该属性指定一个变量保存待包含模板的输出
[var ...]	[var type]	No	n/a	传递给待包含模板的本地参数，只在待包含模板中有效

Include tags are used for including other templates in the current template. Any variables available in the current template are also available within the included template. The include tag must have the attribute "file", which contains the template resource path.

Include 标签用于在当前模板中包含其它模板. 当前模板中的变量在被包含的模板中可用. 必须指定 file 属性，该属性指明模板资源的位置.

You can optionally pass the assign attribute, which will specify a template variable name that the output of include will be assigned to instead of displayed.

如果设置了 assign 属性，该属性对应的变量名用于保存待包含模板的输出，这样待包含模板的输出就不会直接显示了。

Example 7-6. function include
例 7-6. include 函数演示

{include file="header.tpl"}

{* body of template goes here *}

{include file="footer.tpl"}

You can also pass variables to included templates as attributes. Any variables explicitly passed to an included template as attributes are only available within the scope of the included file. Attribute variables override current template variables, in the case they are named alike.

可以在属性中传递参数给待包含模板. 传递给待包含模板的参数只在待包含模板中可见. 如果传递的参数在待包含模板中有同名变量，那么该变量被传递的参数替代.

Example 7-7. function include passing variables
例 7-7. 带传递参数的 include 函数演示

{include file="header.tpl" title="Main Menu" table_bgcolor="#c0c0c0"}

{* body of template goes here *}

{include file="footer.tpl" logo="http://my.domain.com/logo.gif"}

Use the syntax for template resources to include files outside of the $template_dir directory.

包含 $template_dir 文件夹之外的模板请使用模板资源说明的格式.

Example 7-8. function include template resource examples
例 7-8. 使用外部模板资源的 include 函数演示

{* absolute filepath *}
{include file="/usr/local/include/templates/header.tpl"}

{* absolute filepath (same thing) *}
{include file="file:/usr/local/include/templates/header.tpl"}

{* windows absolute filepath (MUST use "file:" prefix) *}
{include file="file:C:/www/pub/templates/header.tpl"}

{* include from template resource named "db" *}
{include file="db:header.tpl"}
