        if($size)
            $size = "?s=$size";
        if(!$userid) {
            if($this->data->showavt) {
                return "$set->url/img/private.png";
            }
        else if($this->data->gender) {
                if(!$gender == 'Male'){
                    return "$set->url/img/male.png";
                }
                else {
                    return "$set->url/img/female.png";
                }
            }
        }
        $u = $this->db->getRow("SELECT `email`, `showavt`, `gender` FROM `".MLS_PREFIX."users` WHERE `userid` = ?i", $userid);

        if(!$u->showavt){   
            return "$set->url/img/private.png";
            }
        else if($u->gender) 
                return "$set->url/img/male.png";
            else    
                return "$set->url/img/female.png";

    }

?>

如果用户是女性的男性，我无法显示头像。 如果用户隐藏他们的头像，我只设法显示私人头像。

试试这个：

<?php

    function getAvatar($userid = 0, $size = null) {
        global $set;
        if($size)
            $size = "?s=$size";
        if(!$userid) {
            if($this->data->showavt) {
                return "$set->url/img/private.png";
            }
        else if($gender = $this->data->gender) {
                if($gender == 'Male'){
                    return "$set->url/img/male.png";
                }
                else {
                    return "$set->url/img/female.png";
                }
            }
        }
        $u = $this->db->getRow("SELECT `email`, `showavt`, `gender` FROM `".MLS_PREFIX."users` WHERE `userid` = ?i", $userid);

        if(!$u->showavt){   
            return "$set->url/img/private.png";
            }
        else if($u->gender) // If gender field in DB is not boolean than try $u->gender == 'Male'
                return "$set->url/img/male.png";
            else    
                return "$set->url/img/female.png";

    }
