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.
|
|

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)

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.
