This returns the template output instead of [displaying](#api.display)
|
|
it. Supply a valid [template resource](#resources) type and path. As an
|
|
optional second parameter, you can pass a `$cache id`, see the [caching
|
|
section](#caching) for more information.

// set a separate cache_id for each unique URL

{textformat wrap=40}
|
|
This is some long-winded disclaimer text that would automatically get wrapped
|
|
at 40 characters. This helps make the text easier to read in mail programs that
|
|
do not wrap sentences for you.

// get $contact_info from db or other resource here
