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
$autoload_filters
variable. Smarty will pass the compiled template code as the first
argument, and expect the function to return the result of the
processing.
Example 14-3. using a template postfilter
<?php // put this in your application function add_header_comment($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... *}
