How to Add ‘Show Posts by Author’ Filter Menu to Admin Posts List

Are you looking for a way to add ‘show posts by author’ filter menu to admin posts list? While there’s probably a plugin for this, we have created a quick code snippet that you can use to add ‘show posts by author’ filter menu to admin posts list in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

/*
add authors menu filter to admin post list for custom post type
*/
function restrict_manage_authors() {
	if (isset($_GET['post_type']) && post_type_exists($_GET['post_type']) && in_array(strtolower($_GET['post_type']), array('CUSTOM_POST_TYPE', 'CUSTOM_POST_TYPE_2'))) {
		wp_dropdown_users(array(
			'show_option_all'	=> 'Show all Authors',
			'show_option_none'	=> false,
			'name'			=> 'author',
			'selected'		=> !empty($_GET['author']) ? $_GET['author'] : 0,
			'include_selected'	=> false
		));
	}
}
add_action('restrict_manage_posts', 'restrict_manage_authors');

function custom_columns_author($columns) {
    $columns['author'] = 'Author';
    return $columns;
}
add_filter('manage_edit-CUSTOM_POST_TYPE_columns', 'custom_columns_author');

Make sure to replace CUSTOM_POST_TYPE to your post type name in the above code.
