Conceptually what I want to do is super simple. In my plugin, I want to add a single path/route to my wordpress site:


... that loads a particular file, like:


I have played with wp-rewrite, flush_rules, add_filter('rewrite_rules_array', xxx), but all I got was for the site to accept the path but display the home page.

Clearly I'm missing something really simple, but I've googled for a while without finding what I need. Any ideas?

The idea is just to programmatically create a path/url in a plugin for a WordPress site (like, "[mysite]/mypath"), and then load an arbitrary html or php file. In case anyone else is looking for something similar, this works for me (in my main plugin function file):

register_activation_hook(__FILE__, 'myplugin_activate'); 
function myplugin_activate () {

function create_custom_page($page_name) {
  $pageExists = false;
  $pages = get_pages();     
  foreach ($pages as $page) { 
    if ($page->post_name == $page_name) {
      $pageExists = true;
  if (!$pageExists) {
    wp_insert_post ([
        'post_type' =>'page',        
        'post_name' => $page_name,
        'post_status' => 'publish',
// End Plugin Activation

//Start Catching URL
add_filter( 'page_template', 'catch_mypath' );
function catch_mypath( $page_template ) {
    if ( is_page( 'mytestpath' ) ) {
        $page_template = __DIR__.'/mypage.html';
    return $page_template;


  • Am I wrong, or could the admin delete the page that was added during plugin activation? Would there be a method of doing this that would not leave a vulnerable page behind? Mar 3, 2018 at 19:07
