   To add a custom column, hook into this filter, and add an item to the $post_columns array. The key should be a string ID, and the value should be the human-readable text to display in the column’s header.

   <?php namespace DemoPlugin; const COLUMN_ID = 'publisher'; /** * Register the custom column. * * @param array $columns Existing columns. * @return array Columns with custom column added. */ function register_column( array $columns ) : array {	$columns[ COLUMN_ID ] = __( 'Publisher', 'demo-plugin' );	return $columns; } add_action( 'manage_posts_columns', __NAMESPACE__ . '\\register_column' ); // You will likely also want to hook into 'manage_posts_custom_column' to // output the column's value. function render_column( string $column_id ) {	if ( $column_id !== COLUMN_ID ) {	return;	}	$post = get_post();	echo esc_html( get_post_meta( $post->ID, '_demo_publisher', true ) ); } add_action( 'manage_posts_custom_column', __NAMESPACE__ . '\\render_column' );

   If the new custom column is only for the default post type, then it needs to check the post type.

   function my_add_new_columns($columns) { $post_type = get_post_type(); if ( $post_type == 'post' ) { $new_columns = array( 'my_featured' => esc_html__( 'Featured', 'text_domain' ), ); return array_merge($columns, $new_columns); } } add_filter( 'manage_posts_columns', 'my_add_new_columns' );

   • Note: If you are using “@Keramot UL Islam” solution, make sure to return a default $columns otherwise it will mess up other post type’s columns. I.E.

      function wpdocs_my_add_new_columns( $columns ) { $post_type = get_post_type(); if ( 'post' === $post_type ) { $new_columns = array( 'my_featured' => esc_html__( 'Featured', 'text_domain' ), ); return array_merge( $columns, $new_columns ); } // must return default $column value return $columns; } add_filter( 'manage_posts_columns', 'wpdocs_my_add_new_columns' );

   Example: To add custom featured image thumbnail column in the post.

   function wpdocs_posts_thumb_columns( $columns ) { $post_new_columns = array( 'post_thumbs' => esc_html__( 'Thumbs', 'text_domain' ), ); return array_merge( $columns, $post_new_columns ); } add_filter( 'manage_posts_columns', 'wpdocs_posts_thumb_columns', 5 ); function wpdocs_posts_custom_columns( $column_name, $id ) { if ( 'post_thumbs' === $column_name ) { the_post_thumbnail( 'thumbnail' ); } } add_action( 'manage_posts_custom_column', 'wpdocs_posts_custom_columns', 5, 2 );

   Example migrated from Codex:

   To add a column showing whether a post is sticky or not:

   function add_sticky_column( $columns ) {	$columns['sticky'] = __('Sticky'); return $columns; } add_filter( 'manage_posts_columns' , 'add_sticky_column' );

   To actually display whether or not a post is sticky, hook the manage_posts_custom_column action.
