Add Member’s birthdate from Backend and shows it on frontside [closed]

Step – 1

Create a custom post type called Birthday

add_action( 'init', 'register_birthday_content_type' );
function register_birthday_content_type() {
    register_post_type( 'birthday', array(
      'labels' => array(
        'name' => 'Birthdays',
        'singular_name' => 'Birthday',
       ),
      'description' => 'Your description',
      'public' => true,
      'menu_position' => 20,
      'supports' => array( 'title', 'editor', 'custom-fields' )
    ));
}

Step – 2

Since you have a birthday date field, I prefer using ACF (http://www.advancedcustomfields.com/)

Install ACF and add additional fields such as birth date and position

Step – 3

Write query to fetch the posts which has birth date = Today.

Here is the documetation: http://www.advancedcustomfields.com/resources/query-posts-custom-fields/

This is one of the quickest way.

I hope this helps.
