A Better Login System. Net.tuts+ has published several great tutorials on user login systems.
Most tutorials only deal with authenticating the user, which allows for two levels of security: logged in and not logged in. For many sites, a finer degree of control is needed to control where users can go and what they can do. Creating an access control list (ACL) system will give you the flexibility for granular permissions. Introduction Imagine you are running a great tutorial site that lets users learn about a wide variety of web development techniques. Your problem You want to restrict users' to only specific pages that their particular account allows access to. The solution Implementing an access control list will allow you a great deal of control over what users can and cannot access on your site.
If you view the demo, available with the downloadable source code, you will be greeted with an index page that tests the ACL for each user. Step 1: Create the Database Step 2: Database Include Step 3: Create the ACL Class. Creating an Advanced Password Recovery Utility. In my last tutorial, 'A Better Login System', a few people commented on how they would like to see a tutorial on password recovery, which is something you don't always see in user access tutorials.
The tutorial I am bringing you today will deal with just that. Using mySQLi, we will learn to recover unencrypted and (one-way) encrypted passwords. Introduction Password recovery is always a useful feature to have on your site; however, many tutorials dealing with user authentication neglect this topic. In this tutorial, I will cover handling encrypted and unencrypted passwords, basic mySQLi functions, and we will also build in a temporary lockout if the user answers the security question incorrectly too many times.
For unencrypted passwords, we will create an email that will email the password to the user's registered email address. IMPORTANT NOTE: This tutorial uses the mysqli interface instead of mysql. Step 1: Database Tables After creating a new database, we need to create three tables: Build An Incredible Login Form With jQuery. One struggle that still remains today in web design is displaying all of the redundant information on every page.
For example, a login form. What if there was a way to easily make the content accessible on every page, but keep it hidden until needed? Well you can, by making a top panel that when clicked, will reveal its self and its content. But we need to make this look nice, so we'll also animate it. In this tutorial, we'll create a sliding panel, that slides in to reveal more content, using JQuery to animate the height of the panel. Step 1 - Photoshop Layout First we need to plan out our layout and make it look cool with Photoshop.
Width="600" height="400"> Here you can see what the demo will look like in its normal state. width="600" height="400"> Here is what the demo will look like when the panel is slid down. Step 2 - Planning the structure First off, we need to build the page's structure. Alright, so the layout of the page is pretty simple. Step 3 - CSS preparation: Classes & ID's.
