Wordpress : Custom columns for edit / post views in the admin

/ Published in: PHP

The code references a custom post type (mysite_listings) and adds custom columns for editing the listings in the admin. This adds custom fields onto the edit / list views.

Note: You will want to change instances of "mysite_listings" with your own post type as well update the column I've defined to match your own.

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

//custom columns
add_action("manage_posts_custom_column", "my_custom_columns_fields");
add_filter("manage_edit-mysite_listings_columns", "my_listing_columns");
 
add_action("admin_init", "admin_init");
 
//custom meta box below post description when editing 
function admin_init(){
  add_meta_box("my-custom-columns-meta", "Listing Details", "my_custom_columns", "mysite_listings", "normal", "low");
}
 
//define listing columns
function my_listing_columns($columns)
{
	$columns = array(
		"cb" => "<input type=\"checkbox\" />",
		"title" => "Listing Title",
		"description" => "Description",		
		"address" => "Address",
		"website" => "Website",
		"phone" => "Phone Number",
		"comments" => "Comments"
	);
	return $columns;
}
//show the custom columns per post->ID

{
	global $post;
	$custom = get_post_custom($post->ID);
 
	if ("ID" == $column) echo $post->ID;
