Sites that require users to log in to access certain information and/or purchase products add an additional layer of potential complication to the usability process. To avoid potential visitor confusion and the possibility for errors, it is important that any login process requires little or no thought on the part of the site visitor.

Once logged in, you must be sure that visitors are able to find the information they want and expect to find. My Account pages need to provide visitors with access and ability to view and change personal information, as necessary.

Login Access

Access to any login page (or the login form itself) should be available consistently across all pages of the site. Be sure the form or link is obvious and easily differentiated from other areas of the web page.

Security

If the information behind your login contains sensitive data, you need to use the appropriate security protocols, assuring visitors that that you take their information's security seriously.

Registration

If visitors are not already registered a link to a new user registration form should be present. It's also smart to have a global link to "register" for any new visitors to the site.

Account benefits

Non registered visitors should be treated to benefits of account registration. This information should be located on the same page as the new user registration form.

Lost password

All login forms should contain an option to reclaim passwords and/or username should they have been forgotten. This information must also be passed securely.

Remember me

You can provide additional convenience (though less security) by giving visitors the option of checking a "remember me" box which will allow them to stay logged in indefinitely.

Privacy

Provide a link to your sites privacy information/policy near the login form submit button or email field. This gives your visitors confidence that you will treat their information with respect.

Status

The visitor's "logged in" status should be displayed at all times with a ready access to logout at their convenience. When additional security is necessary it's a good idea to automatically log them out after a set period of inactivity.

Change info

Once logged in, visitors should have access to change their user information, including usernames, passwords, contact info, payment details, etc.

Change confirmation

Once the visitor has submitted their information to be changed, provide a confirmation screen that shows the old and new info. This prevents errors and helps insure information remains accurate.

Financial details

Provide links to relevant financial information such as transaction history, invoices, balances, payment methods, etc. Provide printable version of this information.

Up-sell opportunities

Visitors that are logged in provide you an interested, captive audience. Consider discreetly utilizing up-sell opportunities - without being overbearing.

Subscribed services

Provide visitors access to the information/services to which they are subscribed. Also provide additional subscription options, if applicable.

Information management

Allow users to change the way they receive information, providing alternate methods such as snail mail, HTML or text based emails or to turning off communication entirely.

When visitors create an account with you they are making a commitment to you to enjoy the services or information that you provide. It's important not to let the usability process break down after visitors are committed. In fact, it's even more important to treat registered visitors respectfully and appropriately, ensuring they have access to the information they need. This develops long-term relationships and keeps them coming back.

What is PHP?

PHP stands for PHP: HyperText Preprocessor, it is a server-side scripting language, and as the name goes, it is to create dynamic and interactive Websites for your visitors. Maybe you currently make your Websites in HTML? HTML alone cannot create dynamic Web pages, HTML is clearly defined as a static language, as it is always static and mainly is used for structuring (or styling, in some cases) a document (or a Web page, if you like).

What do we mean by server-side scripting?

You may already know, but HTML is a client-side language, so the browser translates the HTML code into "bytecode" that the computer can understand, and so the computer translates bytecode into what we can clearly understand, text, for example. Server-side scripting is a little different, a little bit more added to the story. As with PHP, server-side scripting languages have an interpreter inside a machine, that translates the code (in our case, PHP code) to HTML code (that the browser can understand), and then the same process will take place with the browser translating the HTML code to bytecode, and so forth. With server-side scripting languages, you don't need anything adding to your browser or computer, as the interpreter inside the machine that hosts the particular Website does most of the work.

What's the fuss with server-side scripting languages, then?

The thing that makes server-side scripting a must nowadays is because it can generate dynamic Web pages, but what do we mean by dynamic Web pages? Well, imagine you wanted to start a forum, and you used HTML. Okay, you used a form to submit the data and it is sent to your e-mail address, and you have to edit the static Web page every time you want a new post added. That, to me, would be the most annoying job of creating a Website. However, with PHP (or any other server-side scripting language, for that matter), can be completely automated, and you'd not have to edit your file even once! The thing that PHP does, is sends the form data to a different page, saves it in "pre-defined" variables (things that store a value), and using something called a "while loop" that continually loops all the posts saved in the Web page - and that's it! PHP stores the posts in a MySQL database (something that holds data, if you like, like member accounts, etc) and uses that as long-term memory.

But if we're talking about server-side scripting languages, what makes PHP different from the rest? Well, simply put, PHP is probably the best thing that has come into the server-side scripting genre. If you have heard about other scripting languages like Perl or ASP/ASP.NET, you'll come to find that they are extremely hard to learn from. Put it this way, the majority of Web developers that use ASP.NET, for example, are those who have come from a different programming background, like have known VBScript, or other languages that's in relation to ASP.NET, the same with Perl. The difference between PHP and the rest, is PHP is incredibly easy to learn, especially for the newbies towards this industry, and PHP has took several steps to ensure an easy introduction to those newbies to the world of programming. Let's do an example, lets see which is the easiest to understand, out of PHP, VBScript and Perl, by doing a simple "Hello World" program, that outputs text to a Web page:

PHP:

echo "This is some text that'll be shown in a Web page...";

VBScript/ASP.NET:

Response.Write("This is some text that'll be shown in a Web page...");

Perl:

#!/usr/bin/perl

print "content-type: text/html nn";

print "This is some text that'll be shown in a Web page...";

Okay, now I am not going to say things like "well, obviously PHP is the easiest to understand" - as obviously, we all have different preferences, but what I can say is, that they all do the same thing. Which seems the most logical to you? In my opinion, the two most logical ones for me is PHP and VBScript/(ASP.NET).

Now it's up to you which one you want to go ahead with, experiment which one is best for you, after all, we all have dfferent tastes.

Good luck!
