One of my client faced issue with Autor drop down which is in Admin section.
Display the authors in dropdown menu using hooks.
While creating the New post there was problem with the Author field. There are hundreds of irrelevant selections (users) and it’s difficult to select the right one.
WordPress is by default showing all the users in author drop down. I don’t want to show the other users in author drop down.
Hook/Filter – In wordpress Admin -Add new Post section -Display the authors in a dropdown menu using wp_dropdown_users One of my client faced issue with Autor drop down which is in Admin section. Display the authors in a dropdown menu using hooks
I searched for wp_dropdown_users hook or filter. But I did not found any proper solution.
Following articles are found helpful to me.
http://wordpress.org/support/topic/filter-for-post-quick-edit-author-drop-down
http://codex.wordpress.org/Function_Reference/wp_dropdown_users
Using that code I modified the code and I am able to fix the issue. You can put following code in to functions.php file.
/*
* Hook for showing Admin and Author in Add new Post - Admin section dropdown menu
*/
function wpapi_override_wp_dropdown_users($output) {
global $post, $user_ID;
//get the Admin-role users IDs
$admins = getUsersWithRole('admin');
//get the author-role users IDs
$authors = getUsersWithRole('author');
//merge the array
$result = array_merge($admins, $authors);
//array converted into comma seprated string
$authorsall = implode(",", $result);
// return if this isn't the theme author override dropdown
if (!preg_match('/post_author_override/', $output))
return $output;
// return if we've already replaced the list (end recursion)
if (preg_match('/post_author_override_replaced/', $output))
return $output;
// replacement call to wp_dropdown_users
$output = wp_dropdown_users(array(
'echo' => 0,
'name' => 'post_author_override_replaced',
'selected' => empty($post->ID) ? $user_ID : $post->post_author,
'include_selected' => true,
'include' => $authorsall
));
// put the original name back
$output = preg_replace('/post_author_override_replaced/', 'post_author_override', $output);
return $output;
}
add_filter('wp_dropdown_users', 'wpapi_override_wp_dropdown_users');
/*
* Find User IDs by Role
*/
function getUsersWithRole($role) {
$wp_user_search = new WP_User_Search($usersearch, $userspage, $role);
return $wp_user_search->get_results();
}
Using above code, you can load multiple role users in author drop down.

If you want to disable post revision system permanently, you can add following line in wp_config.php file.
define('WP_POST_REVISIONS', false);
But it has some bad issues also. If you have 5 to 10 revision per post and 200 posts then you will have at least 1500 to 2000 entries in table. Most important part is all revisions are unuseful. Each additional revision increase the size of your database thus making the processing time slower and slower.

For getting the wordpress posts we use the following methods. In every wordpress theme we always use the get_posts() vs WP_Query vs query_posts() methods for creating the wordpress theme. We should know about wordpress methods first.
get posts vs new wp_query in wordpress theme
query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the query. It is inefficient (re-runs SQL queries) and will outright fail in some circumstances (especially often when dealing with posts pagination). Any modern WP code should use more reliable methods, like making use ofpre_get_posts hook, for this purpose. TL;DRdon’t use query_posts() ever;
get_posts() is very similar in usage and accepts same arguments (with some nuances, like different defaults), but returns array of posts, doesn’t modify global variables and is safe to use anywhere;
WP_Query class powers both behind the scenes, but you can also create and work with own object of it. Bit more complex, fewer restrictions, also safe to use anywhere.
As per my opinion you should use the WP_Query() method. This is secure to use. If you have a choice, go with WP_Query. Both of the other functions (query_posts() andget_posts()) call WP_Query indirectly.
