我已经创建了一个自定义贴子插件。

在这个插件中创建新的自定义帖子时，我需要添加预定义的文本/值。

是否可以在我的插件中处理这些预定义的文本/值。php文件，并使其处于活动状态？

<?php

add_action( \'init\', \'create_movie_review\' );


function create_movie_review() {
register_post_type( \'movie_reviews\',
array(
\'labels\' => array(
\'name\' => \'Grand Prix Autíčka\',
\'singular_name\' => \'Movie Review\',
\'add_new\' => \'Přidat Nový\',
\'add_new_item\' => \'Add New Movie Review\',
\'edit\' => \'Upravit\',
\'edit_item\' => \'Edit Movie Review\',
\'new_item\' => \'New Movie Review\',
\'view\' => \'View\',
\'view_item\' => \'View Movie Review\',
\'search_items\' => \'Search Movie Reviews\',
\'not_found\' => \'No Movie Reviews found\',
\'not_found_in_trash\' =>
\'No Movie Reviews found in Trash\',
\'parent\' => \'Parent Movie Review\'
),
\'public\' => true,
\'menu_position\' => 15,
\'supports\' =>
array( \'title\', \'editor\', \'comments\',
\'thumbnail\',  ),
\'taxonomies\' => array( \'\' ),
\'menu_icon\' =>
plugins_url( \'images/image.png\', __FILE__ ),
\'has_archive\' => true
)
);
}

add_action( \'admin_init\', \'my_admin\' );

我添加了此代码，但它显示在我需要的所有新帖子/页面中default content only for plugins new post

add_filter( \'default_content\', \'my_editor_content\' );

function my_editor_content( $content ) {

    $content = "This is some custom content I\'m adding to the post editor because I hate re-typing it.";

    return $content;
}

请告知，谢谢

function my_editor_content( $content ) {
$content = "";    
if ( \'movie_reviews\' == get_post_type() ) {
        $content = "This is some custom content I\'m adding to the post editor because I hate re-typing it."; }

        return $content;
