Postfilters

Template postfilters are PHP functions that your templates are ran through after they are compiled. Postfilters can be either registered or loaded from the plugins directory by using load_filter() function or by setting $autoload_filters variable. Smarty will pass the compiled template code as the first argument, and expect the function to return the result of the processing.

<?php

// put this in your application

function add_header_comment($tpl_source, &$smarty)

{

    return "<?php echo \"<!-- Created by Smarty! -->\n\" ?>\n".$tpl_source;

}



// register the postfilter

$smarty->register_postfilter("add_header_comment");

$smarty->display("index.tpl");

?>



{* compiled Smarty template index.tpl *}

<!-- Created by Smarty! -->

{* rest of template content... *}
