Same here…
I’ve got a wp3 site with thousands of users (subscribers).
Currently they’re sending me articles via email.
When I create a new post and try to set the author from the authors’ dropdown list, it takes ages, because the dropdown list is huge.
What can be done?
Thanks.
P.
Yeah this is horrible. the newest version of WordPress required TWO core hacks now to break this instead of just one.
I had to comment out the calls to wp_dropdown_users in these two files, otherwise even my (quite flexible) PHP configuration wound up sending 502 Bad Gateways off and on.
wp-admin/includes/class-wp-posts-list-table.php
wp-admin/includes/meta-boxes.php
There was a ticket for this at one point. It was “fixed” but it really wasn’t. Discussions about optimizing the db queries and only fetching the columns in question were the bulk of it. Really, I want something to be able to short-circuit the code from executing. I tried to hook it by removing the “authordiv” meta box, that didn’t seem to help. Can’t seem to find a plugin method to short-circuit or break this without returning false just to stop the function moving forward to execute the queries/etc…
Agreed. The way WordPress handles users is one of the few complaints I have about it. I’ve found I can’t use some of the functions because of execution time issues. I really think the problem ultimately rests on a less that desirable roles/capability implementation, but that is another fight.
You can use “pre_user_query” filter and “debug_backtrace” to handle query.
HI, i would like to know How do I post under this forum???… i have an advance question…
hi evryone.I can’t login in my admin panel .I got this error message:
Warning: Cannot modify header information – headers already sent by (output started at /home/clakup/public_html/wp-content/themes/evolve/functions.php:5261) in /home/clakup/public_html/wp-includes/pluggable.php on line 897
It gonna be super cool if you guys will help me .
I’m new here ,so sorry if I post in the wrong place.
I think you probably delete: wp_head() in header.php or wp_footer() in footer.php.
It was a empty space in the code in fontion.php .Thanks for your help anyway
I think that version is bad and … I have used it in my own bussines loced in bussines strathfield
Thanks to Oleg Dudkin – for some reason all the digging I did I could not locate the pre_user_query hook.
I wound up doing this:
function _break_user_list(&$object) {
global $wpdb;
$object->query_from = 'FROM '.$wpdb->posts;
$object->where_where = 'WHERE ID=1';
}
add_filter('pre_user_query', '_break_user_list');
This forced it to only look up user ID #1, instead of every user in the database (which was the default behavior due to our role setup)
Voila, no more hacking core!
