// Add callback to admin menu
add_action( 'template_redirect', 'uploadr_redirect' );
// Callback to add menu items
function uploadr_redirect() {
global $wp;
$plugindir = dirname( __FILE__ );
// A Specific Custom Post Type
if ( $wp->query_vars["post_type"] == 'uploadr' ) {
$templatefilename = 'custom-uploadr.php';
if ( file_exists( TEMPLATEPATH . '/' . $templatefilename )) {
$return_template = TEMPLATEPATH . '/' . $templatefilename;
} else {
$return_template = $plugindir . '/themefiles/' . $templatefilename;
}
do_theme_redirect( $return_template );
}
}
function do_theme_redirect( $url ) {
global $post, $wp_query;
if ( have_posts ()) {
include( $url );
die();
} else {
$wp_query->is_404 = true;
}
}
提前谢谢 在对代码进行了大量修改后，我实际上能够与我的一位开发人员朋友交谈 这是
<?php
register_activation_hook( __FILE__, 'create_uploadr_page' );
function create_uploadr_page() {
$post_id = -1;
// Setup custom vars
$author_id = 1;
$slug = 'event-photo-uploader';
$title = 'Event Photo Uploader';
// Check if page exists, if not create it
if ( null == get_page_by_title( $title )) {
$uploader_page = array(
'comment_status' => 'closed',
'ping_status' => 'closed',
'post_author' => $author_id,
'post_name' => $slug,
'post_title' => $title,
'post_status' => 'publish',
'post_type' => 'page'
);
$post_id = wp_insert_post( $uploader_page );
if ( !$post_id ) {
wp_die( 'Error creating template page' );
} else {
update_post_meta( $post_id, '_wp_page_template', 'custom-uploadr.php' );
}
} // end check if
}
add_action( 'template_include', 'uploadr_redirect' );
function uploadr_redirect( $template ) {
$plugindir = dirname( __FILE__ );
if ( is_page_template( 'custom-uploadr.php' )) {
$template = $plugindir . '/templates/custom-uploadr.php';
}
return $template;
}
?>
以下是我从Wordpress插件（受Tom McFarlin启发）添加页面模板的代码解决方案 这是为插件设计的（在插件的根目录中搜索模板文件）。这些文件的格式与直接包含在主题中的格式完全相同。如果需要，这可以更改-查看我的完整教程，了解有关此解决方案的更多详细信息 要定制，只需在_构造方法中编辑以下代码块
$this->templates = array(
'goodtobebad-template.php' => 'It\'s Good to Be Bad',
);
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;
}
/**

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',
);
}
/**

*/
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;
}

public function view_project_template( $template ) {

)] ) ) {
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;

add_action( 'plugins_loaded', array( 'PageTemplater', 'get_instance' ) );
我希望这能帮助您完成以下任务：）我为那些希望从插件向帖子添加模板的人提供了一个通用解决方案。使用过滤器
<?php
add_filter( 'single_template', 'add_custom_single_template', 99 );
function add_custom_single_template( $template ) {
if ( get_post_type() == 'post-type-name'; ) {
return plugin_dir_path( __FILE__ ) . 'path-to-page-template-inside-plugin.php';
}
return $template;
}
?>
wp\u insert\u post'page\u template'=>'goodtobebad template.php'single.php<?php
add_filter( 'single_template', 'add_custom_single_template', 99 );
function add_custom_single_template( $template ) {
if ( get_post_type() == 'post-type-name'; ) {
return plugin_dir_path( __FILE__ ) . 'path-to-page-template-inside-plugin.php';
}
