All the fields are required and cannot be left blank. However, form validation is done before that to make sure that the user is filling the form correctly. After the user clicks the ‘register’ button on the register.php button, the data entered is sent to the database, and this completes a new registration.
The server.php page is then connected to the ‘registration’ database created earlier. After that, the variables are declared and an error array is created. The size can be adjusted as per the requirement however, 100 is sufficient.Įxplanation: The session is started using session_start() method. The data type for username, email and password will be varchar. It will also auto-increment for every new registration. The ‘id’ will be the primary key, it means that it will be unique for every registered user. The database is named ‘registration’, and the table is named ‘users’. The first step is to create a database, and then a table inside it.
After this, the user is redirected to the index.php page where a welcome message and the username of the logged-in user is displayed. The register.php page asks for the desired username, email, and password of the user, and then sends the entered data into the database, once the submit button is clicked.
The session variables are used to display logged in user information in PHP. These are unique for each visitor and are generally used to store user-specific information such as the username, profile picture etc, once the user logs in. After the session is complete, the session variables get destroyed. Session variables exist only while the user’s session is active. Such functionality can be created by using the session variables. In social networking websites like Facebook, Instagram, etc, the username and profile picture of the user that has logged in gets displayed in the header of the website, and that header remains constant, irrespective of the webpage the user has opened.
