fetch() — returns the template output
Description
string fetch(string template,
string cache_id,
string compile_id);
This returns the template output instead of
displaying it.
Supply a valid template resource
type and path. As an optional second parameter, you can pass a
$cache id, see the caching
section for more information.
As an optional third parameter, you can pass a
$compile_id.
This is in the event that you want to compile different versions of
the same template, such as having separate templates compiled
for different languages. You can
also set the
$compile_id variable once instead of passing
this to each call to this function.
Example 14.21. fetch()
<?php
include('Smarty.class.php');
$smarty = new Smarty;
$smarty->setCaching(true);
// set a separate cache_id for each unique URL
$cache_id = md5($_SERVER['REQUEST_URI']);
// capture the output
$output = $smarty->fetch('index.tpl', $cache_id);
// do something with $output here
echo $output;
?>
Example 14.22. Using fetch() to send an email

{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.
{/textformat}
The php script using the PHP
mail() function
<?php
// get $contact_info from db or other resource here
$smarty->assign('contact_info',$contact_info);
$smarty->assign('login_url',"http://{$_SERVER['SERVER_NAME']}/login");
mail($contact_info['email'], 'Thank You', $smarty->fetch('email_body.tpl'));
?>
