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' );Feedback
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' );— By merlinthewarlock —
To add a custom column, hook into this filter, and add an item to the
$post_columnsarray. 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' );Expand full source codeCollapse full source code
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 );Expand full source codeCollapse full source code
Example: This will remove the author, categories, tags and comment columns from backend Posts > All Posts section.
if ( ! function_exists( 'custom_manage_posts_column' ) ) { function custom_manage_posts_column( $columns ) { unset( $columns['author'] ); unset( $columns['categories'] ); unset( $columns['tags'] ); unset( $columns['comments'] ); return $columns; } } if ( has_filter( 'manage_posts_columns' ) ) { add_filter( 'manage_posts_columns', 'custom_manage_posts_column' ); }
