PHP: Site Registration and Confirmation Completed

Over the last two tutorials, we have been building up a user registration and validation system using as much of Dreamweaver's built in functionality as possible. We have built our database and created a form with validation for capturing the users' details, and then sent the user a confirmation email and written a script that tests for a human user and validates them against the database. We also wrote a small script that lets us test our system without having to send emails all over the place. This week we'll finish off our system by creating a small addition to our users.php script, add some functionality for the user to reset their password if they have forgotten it and then create a set of login pages that works with the database structure that we created in the first tutorial.

All the code for a full PHP log-in and confirmation suite is included with this tutorial!

PHP Basics - conditions and loops

In this tutorial we look at conditional processing and the different commands available in PHP to perform this. Conditional processing allows you to choose which parts of your code are run depending on certain conditions, such as data entered by a user or results from a database.

In the second part of this tutorial, we move on to look at loops in PHP. We first look at the PHP for loop, which enables you to repeat a section of code a certain number of times, to perform calculations or to display rows of dynamic output.  We then look at the other types of loop such as the do loop and do … while loop which come in useful in a range of different situations.

Finally, we look at nested loops, which are loops within a loop. These are extremely useful for creating HTML tables, and have a number of different uses such as laying out photos in an online photo gallery.

PHP: Site registration and confirmation with a Validation code Image

In the second part of this series on building a registration and confirmation suite in PHP, Allan builds a testing script so that you can test the pages without being logged on or using a SMTP server, and builds a Validation Code Image display and checker, similar to the one illustrated, so that you can be sure that it's a real person registering, and not an automated script.
