After upgrading to WordPress 3.6, I found a lot of the following error messages in the debug log:
Notice: wpdb::escape is deprecated since version 3.6! Use wpdb::prepare() or esc_sql() instead.
The meaning of this error message is that WordPress 3.6 will discard the escape method of the $wpdp class if it is set. It is recommended to use the preprae method or the esc_sql method instead. Deprecated means that although this version of this method can be used, it will not be updated in the future until it is deleted, so we will finally modify the plug-in that uses this method. Let your blog upgrade in the future without going wrong.
After a round of investigation, it was found that neither plug-ins nor themes used this function for filtering. Finally, it was found that the problem was caused by the sunrise.php file of Multisites.
However, since the sunrise.php file is referenced before the esc_sql() file is defined, we cannot use the esc_sql() function, and $wpdb->prepare cannot be used in the sunrise.php line. Finally, I found that it can be replaced by the $wpdb->_escape method.
So the final modification is to add the following line in the wp-content/sunrise.php file:
$dm_domain = $wpdb->escape( $_SERVER[ 'HTTP_HOST' ] );
Modify to:
