{$smarty} reserved variable

The reserved {$smarty} variable can be used to access several special template variables. The full list of them follows.

保留的 {$smarty} 變數可以用來取得某些相當特殊的樣版變數，這些變數的說明如 下。

Request variables

The request variables such as get, post, cookies, server, environment, and session variables can be accessed as demonstrated in the examples below:

要求變數如 get, post, cookies, server, environment 與 session 等變數取 得方式如下：

Example 4-6. 展示所要求的變數

{* display value of page from URL (GET) http://www.example.com/index.php?page=foo *}
{$smarty.get.page}

{* display the variable "page" from a form (POST) *}
{$smarty.post.page}

{* display the value of the cookie "username" *}
{$smarty.cookies.username}

{* display the server variable "SERVER_NAME" *}
{$smarty.server.SERVER_NAME}

{* display the system environment variable "PATH" *}
{$smarty.env.PATH}

{* display the php session variable "id" *}
{$smarty.session.id}

{* display the variable "username" from merged get/post/cookies/server/env *}
{$smarty.request.username}

Note: For historical reasons {$SCRIPT_NAME} can be accessed directly though {$smarty.server.SCRIPT_NAME} is the proposed way to access this value.

提醒： 因為使用習慣的原因，我們建議使用 {$smarty.server.SCRIPT_NAME} 變數取得 {$SCRIPT_NAME} 的值。

{$smarty.now}

The current timestamp can be accessed with {$smarty.now}. The number reflects the number of seconds passed since the so-called Epoch (January 1, 1970) and can be passed directly to date_format modifier for display purposes.

我們可以使用 {$smarty.now} 取得現在的時間戳記，得到的數字代表從1970 年1月1日開始到現在的秒數，我們可以將得到的數字傳給 date_format 修飾字。

Example 4-7. 使用 {$smarty.now}

{* use the date_format modifier to show current date and time *}
{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}

{$smarty.const}

You can access PHP constant values directly.

我們可以直接取得 PHP 常數變數。

Example 4-8. 使用 {$smarty.const}

{$smarty.const._MY_CONST_VAL}

{$smarty.capture}

The output captured via {capture}..{/capture} construct can be accessed using {$smarty} variable. See section on capture for an example.

由 {capture}..{/capture} 獲得的輸出變數可以使用 {$smarty} 取得，範例 請參閱 capture。

{$smarty.config}

{$smarty} variable can be used to refer to loaded config variables. {$smarty.config.foo} is a synonym for {#foo#}. See the section on config_load for an example.

{$smarty} 變數可以用來參照到已載入的組態變數，如 {$smarty.config.foo} 同義於 {#foo#}，範例請參閱 config_load。

{$smarty.section}, {$smarty.foreach}

{$smarty} variable can be used to refer to 'section' and 'foreach' loop properties. See docs for section and foreach.

{$smarty} 變數可以用來參照到 'section' 與 'foreach' 等遞迴屬性，請參 閱 section 與 foreach 文件。

{$smarty.template}

This variable contains the name of the current template being processed.

此參數內容為現在正在處理的樣版名稱。

{$smarty.version}

This variable contains the version of Smarty the template was compiled with.

此參數內容為 Smarty 的版本數字。

{$smarty.ldelim}

This variable is used for printing the left-delimiter value literally. See also {ldelim},{rdelim}.

此變數用來列印出左阻斷符號，請參閱 {ldelim},{rdelim}。

{$smarty.rdelim}

This variable is used for printing the right-delimiter value literally. See also {ldelim},{rdelim}.

此變數用來列印出右阻斷符號，請參閱 {ldelim},{rdelim}。
