How do you get the parsed HTML of a page on the back end? (Within an Extension Using PHP) EE5

2 Answers 2


I believe you use this extension hook:



Here is an example of how this could work. Set up your extension and register it to run this method on the hook:

public function my_template_post_parse_function($template, $is_partial, $site_id)
    return str_replace("<my-tag>", "My-tag's output!", $template);

Read over the documentation on extension development for more information on how to use extensions and hooks:


  • How do I send the $this->final_template? Where does it come from? Example? Commented Dec 13, 2018 at 21:03
  • I added a simple example.

Just in case someone else is looking for the answer: If after your extension is called you can rebuild the template using the following code

function your_function($obj){
$template_group = "template_group_name"; \\(string)
$template = "template_name"; \\(string)
ee()->uri->page_query_string = $obj->entry('entry_id');\\assign your own entry_id (int)
ee()->load->library('template', NULL, 'TMPL');
ee()->TMPL->fetch_and_parse($template_group, $template, FALSE);
$rendered = ee()->TMPL->parse_globals(ee()->TMPL->final_template);
echo $rendered;

Of course you can display it or set values how ever you want.
