Limiting get_users() results by meta value with LIKE wildcards — at Initial Version

I want to limit the results returned by get_users() to a subset of the users based on some criteria that will be stored in the User Meta table (e.g. all users whose first name begins with M).

Here arr the args I am passing to get_users(): (

[include] => [exclude] => [fields] => all_with_meta [meta_key] => last_name [meta_value] => M% [meta_compare] => LIKE


This is the query the WordPress constructs for me:

[01-Feb-2013 16:01:08 UTC] WP_User_Query Object (

[query_vars] => Array


[blog_id] => 1 [role] => [meta_key] => last_name [meta_value] => M% [meta_compare] => LIKE [include] => [exclude] => [search] => [search_columns] => Array

( )

[orderby] => login [order] => ASC [offset] => [number] => [count_total] => [fields] => all_with_meta [who] =>


[results] => Array

( )

[total_users] => 0 [query_fields] => wp_users.ID [query_from] => FROM wp_users INNER JOIN wp_usermeta ON (wp_users.ID = wp_usermeta.user_id) [query_where] => WHERE 1=1 AND ( (wp_usermeta.meta_key = 'last_name' AND CAST(wp_usermeta.meta_value AS CHAR) LIKE '%M
%%') ) [query_orderby] => ORDER BY user_login ASC [query_limit] =>

As you can see, the LIKE clause is escaped and wrapped with SQL wildcard operators. I can't figure out how to prevent this from happening as what I want is "LIKE 'M%'" to be my actually query.

Currently, "LIKE" prepends and appends wildcards, as in %term%. We could add "%LIKE" and "LIKE%", though that would not help with the situation where you want LIKE taken literally, potentially without % wildcards at all. (Such as using _ as a single-character wildcard, or looking for case insensitive matching.) Probably the best way to add to this API would be to allow for a 'like_escape' => false; that would accept your value as provided. If you'd like to submit a ticket (and patch), this can definitely find its way into 3.6.


I have prepared a patch to meta.php which allows escaped LIKE and NOT LIKE meta compares to work properly.
