  1. In Topic: Problem : There is no wireless interface on the system

    Posted 5 May 2016

    If it's not working at all, it's not going to get a lot worse.

    The primary method for solving issues like these is screwing around with the drivers and settings until something happens, unless you already have an idea what the actual problem is. Mostly stuff like this is just driver issues, or some oddity in the configuration. Windows is built to be more or less idiot proof, so there isn't a great deal of damage you can do within the Windows GUI, or even the CMD emulator.


    The alternative to that is hardware problems, which you wouldn't fix yourself at any rate.

    I'd reiterate my suggestion to boot a Live DVD/USB from a Linux distro (like Ubuntu, for example) and see if the networking works there. If it does, at least you know the problem is with the software, not the hardware.

    First, the obvious question: "Have you tried turning it off and on again?" :)/>

    If the laptop were sitting in front of me, I'd probably start by fiddling with the drivers, and generally just messing around with the settings inside Windows to see if I can shake something loose.

    If that didn't do anything, I might plug in a Live CD/USB for a random Linux distro, and see if the networking works there. That would, at least, eliminate hardware failure as the cause.
  3. In Topic: [Help] User Access Level - Using PHP7 & MySQLi

    Posted 5 May 2016

    Regardless of the group name, my point still stands. It's clearer to use an actual name, rather than a numeric ID or some unclear reference to a name.

    You quite often see this implemented in larger systems with the use of constants, to make the code more readable.
    class User {
        const ROLE_ADMIN = 1;
        const ROLE_STANDARD = 2;
    
        // ... Insert code to fetch and manage user data.
    
        public function hasAdminPrivileges() {
            return $this->getUserLevel() == self::ROLE_ADMIN;
        }
    }
    
    


    I personally don't see a problem with using "admin" as a group name. But then, it's been a long time since I've worked on a system where the group/permission system is so simple you would hard-code group names into PHP conditions. My approach is normally to enable/disable things based on permissions, and then dynamically assign those to groups via a control panel.

    Within my phpmyadmin database...

    Just to clarify, because it has to be said: phpMyAdmin is not actually a database system, just a simple web-based GUI for MySQL databases.

    May seem like an insignificant detail, but it's an important distinction :)/>

    How can I use my UserLevel to decide what an admin can see that a user cannot.

    Like ArtificialSoldier says, store the access level in the session. Then use simple logic to show (or hide) content based on that.

    For example:
    <?php
    // Page: show_blog.php
    
    // This would simply be where you initialize your DB and Session and such.
    require "bootstrap.php";
    
    // Show a blog, based on an ID from the query string. 
    // (Remember to validate the ID first! Skipping that here for simplicity.)
    $blogData = getBlogData($_GET['id']);
    if (!$blogData) {
        header("HTTP/1.0 404 Not Found");
        die('The blog entry you requested does not exist.');
    }
    include "templates/blog_display.php";
    
    // And then show admin controls, if the user level is that of an admin.
    if ($_SESSON['userLevel'] == 'admin') {
        include "templates/blog_admin_controls.php";
    }
    
    


    Note that I use the word 'admin', instead of a numeric level. It's clearer that way. Clarity/simplicity is important when writing code. The more obvious it is, the better.
  5. In Topic: objective c connection with sql database

    Posted 4 May 2016

    Hey.

    Presumably the SQL database in question isn't on the device with the app, but rather online, on a server somewhere?

    If so, I'd generally advice people to set up some sort of web-service in between the app and the database. A REST/SOAP service, for example, is a popular and (usually) fairly straight forward thing to do.

    Gives you more control over the whole thing, and doesn't make you reliant solely on whatever security and performance measures are built into the database server.
