Disable Posts in WordPress

Last modified: October 8, 2018

In sounds kind of funny but sometimes you don’t want to use posts in WordPress. If you are not planning on using them, they should definitely be disabled. Here is how you do that:

Disable Posts in the WordPress Admin

Add a new file in your FTP called disableposts.php and paste this into it:

<?php

/*
Plugin Name: WP Disable Posts
Plugin URI: http://tonykwon.com/wordpress-plugins/wp-disable-posts/
Description: This plugin disables the built-in WordPress Post Type `post`
Version: 0.1
Author: Tony Kwon
Author URI: http://tonykwon.com/wordpress-plugins/wp-disable-posts/

class WP_Disable_Posts

{

  public function __construct()

  {

    global $pagenow;

    /* checks the request and redirects to the dashboard */

    add_action( 'init', array( __CLASS__, 'disallow_post_type_post') );

    /* removes Post Type `Post` related menus from the sidebar menu */

    add_action( 'admin_menu', array( __CLASS__, 'remove_post_type_post' ) );

    if ( !is_admin() && ($pagenow != 'wp-login.php') ) {

      /* need to return a 404 when post_type `post` objects are found */

      add_action( 'posts_results', array( __CLASS__, 'check_post_type' ) );

      /* do not return any instances of post_type `post` */

      add_filter( 'pre_get_posts', array( __CLASS__, 'remove_from_search_filter' ) );

    }

  }

  /**

   * if the user attempts to access any `post` related links

      case 'post-new.php':

        if ( !array_key_exists('post_type', $_GET) && !array_key_exists('taxonomy', $_GET) && !$_POST ) {

          wp_safe_redirect( get_admin_url(), 301 );

          exit;

        }

        break;

    }

    $done = false;

    foreach( $menu as $k => $v ) {

      foreach($v as $key => $val) {

          case 'Posts':

            unset($menu[$k]);

      /* exclude post_type `post` from the query results */

      unset( $post_types['post'] );

    }

    $query->set( 'post_type', array_values($post_types) );

    return $query;

  }

}

new WP_Disable_Posts;

Add the following to functions.php:

include "disableposts.php";

Now when you refresh your admin you won’t see posts anymore.
