#9873 closed defect (bug) (wontfix)

enforce a consistent home and siteurl www. pref

Seen on a few sites. home and siteurl with inconsistent www prefs prevents the admin user's cookie from getting picked up properly, upon logging in.

code I currently use to prevent the issue is this:

add_action('login_head', 'fix_www_pref');

function fix_www_pref() {
	$home_url = get_option('home');
	$site_url = get_option('siteurl');
	$home_www = strpos($home_url, '://www.') !== false;
	$site_www = strpos($site_url, '://www.') !== false;
	if ( $home_www != $site_www ) {
		if ( $home_www )
			$site_url = str_replace('://', '://www.', $site_url);
			$site_url = str_replace('://www.', '://', $site_url);
		update_option('site_url', $site_url);
} # fix_www_pref()

there's probably a better way and a better location for this.

Explicit COOKIE_DOMAIN for www inconsistency

It seems to me that overriding a user's chosen preference in the options table is the wrong way to fix this bug. Since the problem is that it causes inconsistencies in cookie behavior, it makes more sense to me to fix this issue by forcing a value for COOKIE_DOMAIN if a www. inconsistency is detected.

I struggle to believe that this is such a common occurrence that core needs to handle this.

In addition, both of the proposed solutions will break sites which use a different domain name for home and siteurl (eg. and

Feel free to re-open if there's a common situation which leads to this that I'm not accounting for, and/or if someone wants to write a comprehensive patch with unit tests.
