{fetch} {#language.function.fetch}
|
||
|
|
=======
|
||
|
|
|
||
|
|
`{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.
|
||
|
|
|
||
|
|
> **Note**
|
||
|
|
>
|
||
|
|
> 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.
|
||
|
|
|
||
|
|
> **Note**
|
||
|
|
>
|
||
|
|
> If security is enabled and you are fetching a file from the local
|
||
|
|
> file system, `{fetch}` will only allow files from within the
|
||
|
|
> `$secure_dir` path of the securty policy. See the
|
||
|
|
> [Security](#advanced.features.security) section for details.
|
||
|
|
|
||
|
|
- If the `assign` attribute is set, the output of the `{fetch}`
|
||
|
|
function will be assigned to this template variable instead of being
|
||
|
|
output to the template.
