Question

我知道如何创建单个页面和存档页面，但现在我正在尝试将所有内容移动到自定义插件中。到目前为止，我创建了自定义帖子类型“位置”，并创建了我的文件

/templates/archive-location.php
/templates/single-location.php

如何让mysite.com/locations在我的自定义插件中读取我的archive-location.php。

*** ****更新我能够让我的单页工作。现在我该怎么做才能将它包含在任何网站中？例如，我不知道他们的布局，我应该包括页眉和页脚吗？

我需要它，所以如果我删除我的插件，mysite.com/locations就不存在了。

以下是在自定义插件激活期间动态创建自定义模板的代码。

假设我想创建第一个和第二个页面，我想为其分配自定义模板。

将自定义插件的主要文件中的代码放在自定义插件的索引文件下面。

/* Runs when plugin is activated */
register_activation_hook(__FILE__,'news_plugin_install'); 

/* Runs on plugin deactivation*/
register_deactivation_hook( __FILE__, 'news_plugin_remove' );

function news_plugin_install() {
    $newsGagPages = array(
                        'First Page',
                        'Second Page'
                        );

    foreach ($newsGagPages as  $postTitle) {
        $my_post = array(
                    'post_title'    =>$postTitle,
                    'post_status'   => 'publish',
                    'post_author'   => 1,
                    'post_type' => 'page',
                    'post_status'=>'publish');

         if(!get_page_by_title($postTitle))
         {
             $pageID = wp_insert_post($my_post,true);
         }

         if($postTitle =="First Page" ){
            add_post_meta( $pageID, '_wp_page_template', 'template-first.php' );
