# {fetch}
`{fetch}` is used to retrieve files from the local file system, http, or
ftp and display the contents.
## Attributes
| Attribute | Required | Description |
|-----------|----------|------------------------------------------------------|
| file | Yes | The file, http or ftp site to fetch |
| assign | No | The template variable the output will be assigned to |
- If the file name begins with `http://`, the website 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
> `$secure_dir` path of the security policy. See the
> [Security](../../programmers/advanced-features/advanced-features-security.md) section for details.
- If the `assign` attribute is set, the output of the `{fetch}`
function will be assigned to this template variable instead of being
output to the template.
## Examples
```smarty
{* include some javascript in your template *}
{fetch file='/export/httpd/www.example.com/docs/navbar.js'}
{* embed some weather text in your template from another web site *}
{fetch file='http://www.myweather.com/68502/'}
{* fetch a news headline file via ftp *}
{fetch file='ftp://user:password@ftp.example.com/path/to/currentheadlines.txt'}
{* as above but with variables *}
{fetch file="ftp://`$user`:`$password`@`$server`/`$path`"}
{* assign the fetched contents to a template variable *}
{fetch file='http://www.myweather.com/68502/' assign='weather'}
{if $weather ne ''}
<div id="weather">{$weather}</div>
