{fetch} is used to retrieve 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.Замечание
This will not support http redirects, be sure to include a trailing slash on your web page fetches where necessary.
If the file name begins with
ftp://, the file will be downloaded from the ftp server and displayed.-
For local files, either a full system file path must be given, or a path relative to the executed php script.
Замечание
If security is enabled and you are fetching a file from the local file system,
{fetch}will only allow files from within the$secure_dirpath of the securty policy. See the Security section for details. If the
assignattribute is set, the output of the{fetch}function will be assigned to this template variable instead of being output to the template.
