从插件加载front-page.php以覆盖主题

I'm working on a WordPress plugin and thought that to load front-page.php from my plugin, all I had to do was add it to the root directory like I would in a custom theme, but that has not been the case.

How do I get front-page.php from my plugin to load and override any theme/child themes?

I've tried to use the locate_template override from the codex here, but it only flashes my front-page.php and then defaults to index.php.

Thoughts?

Thank you!

You could override the template include wordpress function. You do so when using the 'template_include' filter within your themes or plugins function.php.

add_filter('template_include', 'template_override');
function template_override($template) {
  if (is_front_page()) {
    return TEMPLATE_PATH . 'filename.php';
  }
  // default wordpress behavior
  return $template;
}

You also could run trouble when the static frontpage setting is configured. https://codex.wordpress.org/Creating_a_Static_Front_Page
