任务是为一个页面设置特定模板。模板文件放在我的插件目录中,我找不到正确的方法来获取它作为update_post_meta函数的第三个参数。
我试过了:
update_post_meta( $pas_tasks_page_id, "_wp_page_template", "task-list-template.php" );
和这一个:
update_post_meta( $pas_tasks_page_id, "_wp_page_template", ( ABSPATH . "wp-content/plugins/self-manage/task-list-template.php" ) );
但没有任何作用。我可以在插件中创建模板吗?

指向插件目录中文件的最佳方法是使用plugins_url()
。
关于您的上一个问题,您可以在插件中创建菜单页面(模板)。以下是几个页面的示例:
// Put this in your main script
add_action( 'admin_menu', 'membership_menu' ) ; // Register Admin Menus
// Holds the absolute path to the plugin directory, without trailing slash.
if ( !defined( 'PLUGIN_DIR' ) ) define( 'PLUGIN_DIR', __DIR__ );
// Holds the directory name where the plugin was installed, without slashes.
if ( !defined( 'PLUGIN_DIRNAME' ) ) define( 'PLUGIN_DIRNAME', basename( PLUGIN_DIR ) );
// And this in the same script or your plugin's functions script.
public function membership_menu() {
$OptionsPath = PLUGIN_DIRNAME . '/modules/-options.php';
add_menu_page( 'Membership', 'Membership', 'administrator', $OptionsPath, '', plugins_url( '/' . PLUGIN_DIRNAME . '/images/.png' ) );
add_submenu_page( $OptionsPath, 'Membership Settings', 'Settings', 'administrator', $OptionsPath, '' );
}

您 CAN 从插件中添加页面模板。
这是我的代码解决方案(受Tom McFarlin启发)。
注意 - 这是页面的解决方案,但您还需要配置自定义帖子类型以接受页面模板。
这是为插件设计的(在插件的根目录中搜索模板文件)。如果需要,可以更改此内容 - 有关此解决方案的更多详细信息,请查看我的完整教程http://www.wpexplorer.com/wordpress-page-templates-plugin/。这些文件的格式也完全相同,就像它们直接包含在主题中一样。
要自定义,只需在__construct方法中编辑以下代码块;
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
完整代码;
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 );

);
// Just to be safe, we check if the file exist first

return $file;

else { echo $file; }
