If you don’t wish to always click the “Title” column to sort your posts by title, you can place this code in either your currently active WordPress theme’s functions.php file, or within a plugin. This will automatically always sort your posts for you, so you don’t have to click the title column every time.
You can use this for setting default sort order on post types.
/* Sort posts in wp_list_table by column in ascending or descending order. */
function custom_post_order($query){
/*
Set post types.
_builtin => true returns WordPress default post types.
_builtin => false returns custom registered post types.
*/
$post_types = get_post_types(array('_builtin' => true), 'names');
/* The current post type. */
$post_type = $query->get('post_type');
/* Check post types. */
if(in_array($post_type, $post_types)){
/* Post Column: e.g. title */
if($query->get('orderby') == ''){
$query->set('orderby', 'title');
}
/* Post Order: ASC / DESC */
if($query->get('order') == ''){
$query->set('order', 'ASC');
}
}
}
if(is_admin()){
add_action('pre_get_posts', 'custom_post_order');
}
You can use some of these example conditions…
/* Effects all post types in the array. */
if(in_array($post_type, $post_types)){
}
/* Effects only a specific post type in the array of post types. */
if(in_array($post_type, $post_types) && $post_type == 'your_post_type_name'){
}
/* Effects all post types in the array of post types, except a specific post type. */
if(in_array($post_type, $post_types) && $post_type != 'your_post_type_name'){
}
If you wanted to apply this sorting on ALL post types, regardless of whether or not they are “built-in”…
Change this:
$post_types = get_post_types(array('_builtin' => true), 'names');
To this:
$post_types = get_post_types('', 'names');
