Requirement:
If you want to add endpoint, let say “books” to CPT author, and wants to change view in template.
Solutions:
No need to use “add_rewrite_endpoint” function because as of today, we can not add endpoint to CPT only ( we can add endpoints to either page or archives or all links, etc using add_rewrite_endpoint function )
So how to do it ? Simple, only two functions and use if condition in template file to show list of books or whatever…
<?php
function myplugin_register_query_vars( $vars ) {
$vars[] = 'books';
return $vars;
}
add_filter( 'query_vars', 'myplugin_register_query_vars' );
function myplugin_rewrite_rule() {
add_rewrite_rule( 'author/([^/]+)/books/?', 'index.php?post_type=author&name=$matches[1]&books=true','top' );
}
add_action('init', 'myplugin_rewrite_rule', 10, 0); ?>
In template just check if condition as follow:
if( get_query_var('evaluate') ){
// modify view here
} else {
// default code could be the_content();
}
