I'm unable to find a XML-RPC method called wp.getUsers
in wp-includes/class-wp-xmlrpc-server.php
. Could it be, that you're using an additional plugin that extends the basic behavior of WordPress?
A simple google search for 'wp.getUsers' points me to the the github repo of Max Cutler and the class wp-xmlrpc-modernization. There you have a method wp.getUsers
which accepts a filter
array as 4th parameter.
The optional $filter parameter modifies the query used to retrieve users.
* Accepted keys are 'number' (default: 50), 'offset' (default: 0), and 'role'.
EDIT
wp.getUsers
is using get_users
/ WP_Users_Query
in the background. Therefore you have to set the number
parameter to false
if you don't want a LIMIT
clause in the SQL statement.
Here is a snippet from the WP_Users_Query class which builts the SQL statement based on the parameters.
// limit
if ( $qv['number'] ) {
if ( $qv['offset'] )
$this->query_limit = $wpdb->prepare("LIMIT %d, %d", $qv['offset'], $qv['number']);
else
$this->query_limit = $wpdb->prepare("LIMIT %d", $qv['number']);
}
Unfortunately the wp-xmlrpc-modernization
plugin filters the parameter number
with the function absint
which sanitize a boolean into an integer. You have to edit the plugin and remove/change this filter on line 808.
$query['number'] = ( isset( $filter['number'] ) ) ? absint( $filter['number'] ) : 50;
