[wp-hackers] edit.php custom post type customisations

[Erick Hitter]

There are two hooks, one action and one filter, that let you modify the
columns on the edit screen. The filter *manage_posts_columns* provides
access to the columns array, while the action *manage_posts_custom_column* is
used to add content to the new column(s).

The code below is used specifically for a custom post type. Since I
abstracted this from a custom post type class, there are some references to
class properties. This example adds a column to show custom taxonomy terms
associated with the posts, as well as their order.

function filter_manage_posts_columns( $columns ) {
global $pagenow;
 if( $pagenow == 'edit.php' && isset( $_GET[ 'post_type' ] ) && $_GET[
'post_type' ] == $this->post_type ) {
 $columns_a = array_slice( $columns, 0, 2 );
$columns_a[ $this->reports_taxonomy ] = 'Report Categories';
 $columns_a[ 'menu_order' ] = 'Order';
$columns_b = array_slice( $columns, 2 );
 $columns = array_merge( $columns_a, $columns_b );
}
 return $columns;
}
add_filter( 'manage_posts_columns', array( $this,
'filter_manage_posts_columns' ) );

function action_manage_posts_custom_column( $column, $postid ) {
if( $column == $this->reports_taxonomy ) {
 $report_categories = get_the_terms( $postid, $this->reports_taxonomy );
if( is_array( $report_categories ) && !empty( $report_categories ) ) {
 $i = 1;
foreach( $report_categories as $report_category ) {
echo $report_category->name;
 if( $i < count( $report_categories ) ) echo ', ';
 $i++;
}
}
 }
 if( $column == 'menu_order' ) {
 global $post;
echo $post->menu_order;
}
}
add_action( 'manage_posts_custom_column', array( $this,
'action_manage_posts_custom_column' ), 10, 2 );

Hope this helps,
Erick
