{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 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.

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
