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: 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' ); }
