First of all we need to design the Sign-In webpage. Commonly what we see on a Sign-In webpage. There is username and password form boxes and a button to sign in to the profile page of user.
Upload the whole directory contents. The registration form In order to create a user account, we need to gather a minimal amount of information from the user. We need his name, his email address and his desired username and password.
Of course, we can ask for more information at this point, but a long form is always a turn-off. Here is the registration form: Note that we are using the password widget for better usability.
Form validation At this point it is a good idea to put some form validation code in place, so we make sure that we have all the data required to create the user account. We need to check if name and email, and password are filled in and that the email is in the proper format.
The form submission is then saved to the database table. We send an email to the user requesting confirmation. Then we intimate the admin that a user has registered.
Saving the data in the database Now that we gathered all the data, we need to store it into the database. Here is how we save the form submission to the database.
After logging in, we make sure that the table is existing. If not, the script will create the required table. Then we make sure that the username and email are unique. If it is not unique, we return error back to the user.
The database table structure This is the table structure. Here is the code: Notice that we allow 32 characters for the password field. We do this because, as an added security measure, we will store the password in the database encrypted using MD5. Inserting the registration to the table Here is the code that we use to insert data into the database.Description $_SERVER is an array containing information such as headers, paths, and script locations.
The entries in this array are created by the web server.
There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. Figure 3: Above output checks the entered data is letters or include any other char also.
Conclusion: Tutorial covered three validation scheme. Two of them are using regular expression for matching and the other one is simple so not writing regex but if you want you can write a regex for this case also.
Using above mentioned steps you can easily create registration and login Script in PHP and MySQLi with Validation. We hope this tutorial help you to create this functionality. If you found useful please share it and leave your feedback.
Today we are making a cool & simple login / registration system. It will give you the ability to easily create a member-only area on your site and provide an easy registration process. It is going to be PHP driven and store all the registrations into a MySQL database.
