Exclude certain pages and posts?

Hi Ratethetrainers,

On the faq page I have some examples of excluding posts:

function dfi_skip_page ( $dfi_id, $post_id ) {
  if ( $post_id == 23 ) {
    return 0; // invalid id
  }
  return $dfi_id; // the original featured image id
}
add_filter( 'dfi_thumbnail_id', 'dfi_skip_page', 10 , 2 );

Do you know how to implement this or do you need more guidance?

NP.

Create wp-content/plugin/dfi-exceptions.php

<?php
/**
 * Plugin Name: Default Featured Images Exceptions.
 * Plugin URI: https://ww.wp.xz.cn/support/topic/exclude-certain-pages-and-posts-1
 * Version: 0.9
 * License: GPL2
 */

function dfi_exceptions_skip_page ( $dfi_id, $post_id ) {
  $exclude_ids = array(
    2,  // 1 id per line and don't forget the comma
    8,
  );
  if ( in_array($post_id, $exclude_ids) ) {
    return 0; // don't display DFI
  }
  return $dfi_id; // the original featured image id
}
add_filter( 'dfi_thumbnail_id', 'dfi_exceptions_skip_page', 10 , 2 );

And enable the plugin in the wp-admin.
I’s can be found in the edit page in the url.
Hope this helps.
Let me know how it goes.

Do you know how to add/edit files for WordPress? With FTP or something like that.
