##

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. Another use for compile_id is when you use more than one $template_dir but only one $compile_dir. Set a separate `compile_id` for each $template_dir, otherwise templates of the same name will overwrite each other. You can also set the $compile_id variable once instead of passing this to each call to this function.

Example 1. fetch
`<?php include("Smarty.class.php"); $smarty = new Smarty; $smarty->caching = true; // only do db calls if cache doesn't exist if(!$smarty->is_cached("index.tpl")) { // dummy up some data $address = "245 N 50th"; $db_data = array( "City" => "Lincoln", "State" => "Nebraska", "Zip" => "68502" ); $smarty->assign("Name","Fred"); $smarty->assign("Address",$address); $smarty->assign($db_data); } // capture the output $output = $smarty->fetch("index.tpl"); // do something with $output here echo $output; ?>`
