Plugin API/Filter Reference/manage edit-post type columns

Contents

Description

Applied to the list of columns to print on the manage posts screen for a custom post type. Filter function argument/return value is an associative array where the element key is the name of the column, and the value is the header text for that column.

In WP 3.1, manage_edit-${post_type}_columns has been supplanted by manage_${post_type}_posts_columns.

See also the action manage_posts_custom_column, which alters the column information for each post in the edit table.

Built-in Column Types

Note: Listed in order of appearance. By default, all columns supported by the post type are shown.

cb 
Checkbox for bulk actions.
title 

Post title.

Includes "edit", "quick edit", "trash" and "view" links. If $mode (set from $_REQUEST['mode']) is 'excerpt', a post excerpt is included between the title and links.

author 
Post author.
categories 
Categories the post belongs to.
tags 
Tags for the post.
comments 
Number of pending comments.
date 
The date and publish status of the post.


Examples

Add Columns

Suppose you have a 'books' custom post type and you want to add the publisher and book author in the edit page but remove the post author. 

function set_edit_book_columns($columns) {
    unset($columns['author']);
    return array_merge($columns, 
              array('publisher' => __('Publisher'),
                    'book_author' =>__( 'Book Author')));
}
add_filter('manage_edit-books_columns' , 'set_edit_book_columns');

Replace Columns

Here's another example that completely replaces the columns, rather than adding and removing specific ones. 

function set_edit_book_columns($columns) {
    return array(
        'cb' => '<input type="checkbox" />',
        'title' => __('Title'),
        'date' => __('Date'),
        'publisher' => __('Publisher'),
        'book_author' =>__( 'Book Author')
    );
}
add_filter('manage_edit-books_columns' , 'set_edit_book_columns');

Note the header for the 'cb' column is a checkbox, so that the checked posts can be toggled between all and none.
