Wordpress 重写规则、端点并显示适当的模板

Question

I have been given a task that requires me to create a new endpoint/permalink.

Something like www.myswebsite.com/users where a list of users will be shown. Then www.mywebsite.com/users/1 will show the information of user 1.

THAT part if done. I have the url set, visiting the url serves the appropriate template to the user. The individual information is shown as intended.

However... I am making a mistake because the users.php template is being shown for ALL other urls. So the base url www.mywebsite.com is also showing www.mywebsite.com/users template. How can I fix this?

Below is the code in my plugin. Should you need more information from me, please don't hesitate to ask.

I know my problem is at the get_new_template function but I am not well versed in Wordpress to determine the correct if/else block.

<?php
/*
* Plugin Name: User Endpoint
* Description: Providing An Endpoint For Data Consumption
* Version: 1.0.0
*/

// Add a new var to query vars
function result_add_query_vars( $vars ){
    $vars[] = 'users';
    return $vars;
}
add_filter( 'query_vars', 'result_add_query_vars' );

// Register ReWrite-Rules
function myplugin_rewrite_tag_rule() {
    add_rewrite_endpoint( 'users', EP_ROOT );

    add_rewrite_rule(
        '^users/([^/]*)/?',
        'index.php?pagename=$matches[1]&param=foo',
        'top'
    );
}
add_action('init', 'myplugin_rewrite_tag_rule', 10, 0);

// Register Template To Show At End POint
function get_new_template( $original_template ) {
  if ( get_query_var('users/') ) {
        return dirname(__FILE__) . '/user.php';
    }   else {
        return dirname(__FILE__) . '/users.php';
    }
}
add_filter( 'template_include', 'get_new_template' );

// Flush Permalinks
function flush_permalinks() {
    flush_rewrite_rules();
}

register_activation_hook(__FILE__, 'flush_permalinks');

You are telling WP to use the same template for all here and your did not return the original template for other pages that do match your case. See code below for fix:

// Register Template To Show At End Point
function get_new_template($original_template)
{
    global $wp_query;

    // /users or /users/xxxx
    if (isset($wp_query->query['users'])) {
        // "user id"
        $page = $wp_query->query['users'];

        $template = $page >= 1 ? '/user.php' : '/users.php';

        return dirname(__FILE__) .  $template;
    }

    return $original_template;
}
add_filter('template_include', 'get_new_template');
