## shortcode – How to change page title (from a plugin) in twentytwentyone theme

Question

First, is it even possible to change the page title from a plugin (specifically, from a shortcode defined in a plugin)? This answer says no, but there are certainly reasonable use cases for it. Like, say, my use case (the shortcode displays detail page content for an item of a collection … so, I put the shortcode on a page; what’s the page title supposed to be? It depends on the detail item.).

I have tried every method I can find:

$_SESSION['custom_page_title'] =$eventData['eventtitle'];

//attempt 1
function my_custom_title( $title ) { //$title is an array of title parts, including one called title

$title['title'] = stripslashes($_SESSION['custom_page_title']);

return $title; } //attempt 2 add_filter("pre_get_document_title", "my_callback"); function my_callback($old_title){
return stripslashes($_SESSION['custom_page_title']); } //attempt 3 add_filter('the_title','some_callback'); function some_callback($data){
return stripslashes($_SESSION['custom_page_title']); } //attempt 4 add_filter( 'wp_title', 'custom_titles', 10, 2 ); function custom_titles($title, $sep ) { //Check if custom titles are enabled from your option framework if ( ot_get_option( 'enable_custom_titles' ) === 'on' || (1 == 1)) {$title = stripslashes($_SESSION['custom_page_title']); } return$title;
}


But none of them work (with default twentytwentyone theme).

Is it possible, and if so, how?
