Creating Custom Post Types in WordPress (using a plugin)

Post Types refers various structured data. WordPress come up with default Post Types. Such as post, page, attachment, revision and nav-menu-item. What happens if you want to create your own post type. That could be possible and obviously WordPress support for Custom Post Types. Lets see how we can use this feature in WordPress.

Before starting the coding you need to know there were reserved Post Types and we can’t use those because WordPress is using.

  • post
  • page
  • attachment
  • revision
  • nav_menu_item
  • custom_css
  • customize_changeset

Addition to these following Post Types should not be used.

  • action
  • author
  • order
  • theme

Other than these any name you can use for creating Custom Post Types. If you can prefix the Custom Post name, that is a good practice.

Definition for registering a post type is

<?php register_post_type( $post_type, $args ); ?>

$post_type – Name of the Post_type. Name should be a String and it is Required. Also can contain maximum of 20 characters without any capital letters or spaces.

while($loop->have_posts()) : $loop->the_post();
?>
<div class="book-item">
    <?php the_post_thumbnail(); ?>
