Examples: User registration system

Let’s assume we want to create a registration system which will store the following:

a username
a password
user’s first name
user’s last name
user’s email address

Use the list of attributes above to generate the User object for PHP 4 and download the zip file.

Then, unzip the contents and rename the object file to class.user.php. At this point, this is what you should have in a folder somewhere on your system

Next, open class.user.php file, and in the header region, you should find the SQL query to create the table needed by your object. Once your table is created, open the configuration file and edit it so that the wrapper can connect to your database.

Now, let’s assume you already have a web registration form (see index.html). If you look at the source code for the web form, you’ll find 6 inputs:

username
password1
password2
firstname
lastname
emailaddress

All we need to do now is process the data that’s submitted from the form, create a USER object and Save it to the database.

This is the simplified code to process the data when the form is submitted:

$user = new User();
$user->userName = $_POST['username'];
if ($_POST['password1'] == $_POST['$password2'])
{
$user->password = $_POST['password1'];
}
$user->firstName = $_POST['firstname'];
$user->lastName= $_POST['lastname'];
$user->emailAddress= $_POST['emailaddress'];
if ($user->Save())
{
echo "user successfully saved";
}
