查询wordpress数据库[关闭]

Can anyone see whats wrong with this syntax? I've consulted the wordpress codex page and the syntax seems to be correct..

$result = $wpdb->query($wpdb->prepare( "SELECT * FROM {$wpdb->prefix}users WHERE username = %s AND password = %s, array( $username, $password )"));

Thanks

try:

 $result = $wpdb->query($wpdb->prepare( "SELECT * FROM     {$wpdb->prefix}users WHERE username = %s AND password = %s", array( $username, $password )));

your quotes are incorrect.
