Output Filters

Output filter plugins operate on a template's output, after the template is loaded and executed, but before the output is displayed.

string smarty_outputfilter_ name (string $template_output, object &$smarty)

The first parameter to the output filter function is the template output that needs to be processed, and the second parameter is the instance of Smarty invoking the plugin. The plugin is supposed to do the processing and return the results.
