fetch

Attribute Name Type Required Default Description
file string Yes n/a the file, http or ftp site to fetch
assign string No n/a the template variable the output will be assigned to

属性 类型 是否必须 缺省值 描述
file string Yes n/a 待请求的文件,http或ftp方式.
assign string No n/a 输出值将被赋给模板变量的名称

fetch is used to fetch files from the local file system, http, or ftp and display the contents. If the file name begins with "http://", the web site page will be fetched and displayed. If the file name begins with "ftp://", the file will be fetched from the ftp server and displayed. For local files, the full system file path must be given, or a path relative to the executed php script.

fetch 用于从本地文件系统、HTTP或FTP上取得文件并显示文件的内容. 如果文件名称以"http://"开头,将取得该网站页面并显示. 如果文件名称以"ftp://"开头,将从ftp服务器取得该文件并显示.

If you supply the special "assign" attribute, the output of the fetch function will be assigned to this template variable instead of being output to the template. (new in Smarty 1.5.0)

如果指定了 "assign" 这个特殊属性,该函数的输出值将被赋给由 assign 指定的模板变量,而不是直接输出.(Smarty 版本 1.5.0 新特性)

Technical Note:This will not support http redirects, be sure to include a trailing slash on your web page fetches where necessary.

技术要点:该函数不支持HTTP重定向,如果要取得web默认页,比如想取得www.domain.com的主页资料,但是不知道主页的具体名称,可能是index.php或index.htm或default.php等等,可以直接使用该站点的url,记得在url结尾处加上反斜线.

Technical Note:If template security is turned on and you are fetching a file from the local file system, this will only allow files from within one of the defined secure directories. ($secure_dir)

技术要点:如果模板的安全设置打开了,当取本地文件时只能取位于定义为安全文件夹下的资料. ($secure_dir)

Example 8-5. fetch
例 8-5. fetch 函数演示

{* include some javascript in your template *} {fetch file="/export/httpd/www.domain.com/docs/navbar.js"} {* embed some weather text in your template from another web site *} {fetch file="http://www.myweather.com/68502/"} {* fetch a news headline file via ftp *} {fetch file="ftp://user:password@ftp.domain.com/path/to/currentheadlines.txt"} {* assign the fetched contents to a template variable *} {fetch file="http://www.myweather.com/68502/" assign="weather"} {if $weather ne ""} {$weather} {/if}
