这里是我从WordPress插件（由汤姆·麦克法林启发）添加页面模板代码解决方案。
这是为插件而设计的（在插件的根目录下搜索模板文件）。这些文件的格式也与它们直接包含在主题中的格式完全相同。这可以根据需要进行更改 - 请查看我的完整教程http://www.wpexplorer.com/wordpress-page-templates-plugin/以获取有关此解决方案的更多详细信息。
要自定义，只需编辑__construct方法中的以下代码块;
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
Full code;
class PageTemplater {
/**
* A Unique Identifier
*/
protected $plugin_slug;
/**
* A reference to an instance of this class.
*/
private static $instance;
/**
* The array of templates that this plugin tracks.
*/
protected $templates;
/**
* Returns an instance of this class.
*/
public static function get_instance() {
if(null == self::$instance) {
self::$instance = new PageTemplater();
}
return self::$instance;
}
/**
* Initializes the plugin by setting filters and administration functions.
*/
private function __construct() {
$this->templates = array();
// Add a filter to the attributes metabox to inject template into the cache.
add_filter(
'page_attributes_dropdown_pages_args',
array($this, 'register_project_templates')
);
// Add a filter to the save post to inject out template into the page cache
add_filter(
'wp_insert_post_data',
array($this, 'register_project_templates')
);
// Add a filter to the template include to determine if the page has our
// template assigned and return it's path
add_filter(
'template_include',
array($this, 'view_project_template')
);
// Add your templates to this array.
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
}
/**
* Adds our template to the pages cache in order to trick WordPress
* into thinking the template file exists where it doens't really exist.
*
*/
public function register_project_templates($atts) {
// Create the key used for the themes cache
$cache_key = 'page_templates-' . md5(get_theme_root() . '/' . get_stylesheet());
// Retrieve the cache list.
// If it doesn't exist, or it's empty prepare an array
$templates = wp_get_theme()->get_page_templates();
if (empty($templates)) {
$templates = array();
}
// New cache, therefore remove the old one
wp_cache_delete($cache_key , 'themes');
// Now add our template to the list of templates by merging our templates
// with the existing templates array from the cache.
$templates = array_merge($templates, $this->templates);
// Add the modified cache to allow WordPress to pick it up for listing
// available templates
wp_cache_add($cache_key, $templates, 'themes', 1800);
return $atts;
}
/**
* Checks if the template is assigned to the page
*/
public function view_project_template($template) {
global $post;
if (!isset($this->templates[get_post_meta(
$post->ID, '_wp_page_template', true
)])) {
return $template;
}
$file = plugin_dir_path(__FILE__). get_post_meta(
$post->ID, '_wp_page_template', true
);
// Just to be safe, we check if the file exist first
if(file_exists($file)) {
return $file;
}
else { echo $file; }
return $template;
}
}
add_action('plugins_loaded', array('PageTemplater', 'get_instance'));
