将属性/参数添加到类中的现有方法

Question

I have a class admin user which has some rights to modify user data. I want to add two or more attributes to this method to complete the required functionality.

function update_user_by_admin($new_level, $user_id, $def_pass, $new_email, $active, $confirmation = "no", $staff_salary, $set_duty_timings) {
    $this->user_found = true;
    $this->user_access_level = $new_level;
    $this->set_staff_salary=$staff_salary;
    if ($def_pass != "" && strlen($def_pass) < 4) {
        $this->the_msg = "Password is too short use the min. of 4 chars.";
    } else {
        if ($this->check_email($new_email)) {
            $sql = "UPDATE %s SET access_level = %d, email = '%s', active = '%s', salary='salary'";
            $sql .= ($def_pass != "") ? sprintf(", pw = '%s'", md5($def_pass)) : "";
            $sql .= " WHERE id = %d";
            $sql_compl = sprintf($sql, $this->table_name, $new_level, $new_email, $active, $user_id);
            if (mysql_query($sql_compl)) {
                $this->the_msg = "Data is modified for user with id#<b>".$user_id."</b>";
                if ($confirmation == "yes") {
                    if ($this->send_confirmation($user_id)) {
                        $this->the_msg .= "<br>...a confirmation mail has been sent to the user.";
                    } else {
                        $this->the_msg .= "<br>...ERROR no confirmation mail is sent to the user.";
                    }
                }
            } else {
                $this->the_msg = "Database error, please try again!";
            }
        } else {
            $this->the_msg = "The e-mail address is invalid!";
        }
    }
}

how do I add new parameter code here?

Answer 1

Your choices are to edit the class itself, or to code a new class that inherits from the class and implements your two extra methods.

If you go for the inheritance approach, you would then need to update any code that instantiates that class and make it instantiate your class instead as required.
