Template postfilters are PHP functions that your templates are ran through
after they are compiled. Postfilters are processed in the order they are
registered or loaded
from the plugin
directory. Smarty will pass the compiled template code as the first
argument, an expect the function to return the result of the
processing.
Example 7-2. using a template postfilter <?php
// put this in your application
function add_header_comment($tpl_source)
{
return "<?php echo \"<!-- Created by Smarty! -->\n\" ?>\n".$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... *} |
