根据帖子类型[关闭]在function.php中包含文件

Question

I want to include different file in function.php file of my wordpress theme based on different custom post type using admin_init hook. Is it possible?

I found the solution and added as an answer.

Answer 1

add_action('admin_init', 'include_files');

function include_files()
{
    global $pagenow;

    if ('post.php' == $pagenow && isset($_GET['post']) )
    {
        $post_type = get_post_type(esc_attr($_GET['post'])) ;
    }

    else if ('post-new.php' == $pagenow && isset($_GET['post_type']) )
    {
        $post_type = $_GET['post_type'];
    } 

    if($post_type == 'custom_post'){
        include_once('file1.php');
    }else{
        include_once('file2.php');
    } 
}
