Then we will compare the plain text password with password hash from database that we fetched from previous step. If it return true, then we will create the session and redirect the user to members area page. Otherwise, we will return an error message. User can enter valid user name and password combination or a valid email and password combination.
To complete the final step in User Login process, creating the session. While comparing the passwords, if it returns true. After login, there should be a way to logout the user from system. Save this code into check-login. We will include this file on the authenticated pages section, those pages will be accessed by logged in users only. Save this code into if-loggedin. We will include this file login. If the session is set, then the user will be redirected to dashboard page.
Otherwise, user will stay on the same login or register page. You can create the files by combining above snippets of code, For any reason if you are not able to combine those files. You can access the complete coding files from here.
CSRF Tokens helps us to protect form submissions, that is only the authentic and valid form submissions will only be accepted. That means session id before login and after login are different. In addition to the above Security measures, you can add more security by adding these features.
These features only available on paid script. We should Limit the number of login attempts that a user can try, if he is having multiple failed login attempts. With this we can eliminate the abusing users and the users who are using unnecessary server resources. We should log the user Login attempts with their ip address, both successful and failed login attempts. So that we can use this login attempts information while Limiting the Login attempts and also in eliminating Brute Force Attacks. I hope this User Login System is helpful to you, now you can use this Login System in your web applications.
If you have any queries, let me know through the comment form below. If you need additional features, Download the source code of the project that you have seen in the demo video with the form below. If you need any customisations, Send me an Email on the download email you received with your requirement customisation is a paid service based on your requirement. Explaning About table structure Here is the SQL code of users table, you can use this code to create the table with the required columns.
With these three columns username, email and password. We will check the user account. This is the brief description of users table. Share this:. In the body I added three form areas auto-generated by the class: two in the login section and one in the registration section. You can also see that I separated them in tabs. You can find a lot of tutorials about Bootstrap on how to work with tabs. The first form will be used for login, the next one for account verification, and the last one for registration.
In the main. This is very useful if we want to separate the frontend from the backend. The first two sections in the JavaScript code are for switching between tabs. Next I use the submit buttons in every form. The last function at the bottom is a function to check if the inserted email address is valid. It will not check if the server exists but just if the format may be valid. For login the script gets the posted data and passes it to the login method of the class.
If the login succeeds, it will assign the user data to session login variables and returns nothing as the result. If there is an error it will print it. As in login process, this is also a very simple code sample, where I use the registration method in the user class.
If a registration passes then we will print a confirmation message or an error message instead. After registration the user needs to activate his account. So we are using here the emailActivation method. Again a strait forward code sample that outputs an error message if the activation fails, or nothing if it passes. For the logout process I use logout method in the user class.
After logout process is conclude we simply redirect the user to index. The logout process is not started via AJAX in this example. An important file I need to describe is the config. It is necessary to specify the database connection details and to initiate the session. This login and registration class will not work without sessions.
It also will creates the user class object so we can use it in every other file. As you saw before we included this script every time after the class itself. Also we need to specify the files we are using in the HTML generation functions.
In this case user. You can customize these files. After logging in, the users have a section on the site where they can see what non-logged visitors can see because it is only for registered users. For this tutorial I created an example of what could be that section in the file user. You may notice two cases. If a normal user is logged in it will show him only his information. But if the user is an administrator, in this case his role ID is 2 you can change this to any ID number then he sees a list off all the users in the system.
Currently this class does not support assuring that only one use is logged with one account at a time. That is because the database does not store the sessions initiated for each user. That could be achieved with an additional database table that stores the session identifier of each user active session.
Additionally using a PHP session handler that stores session data in a database table, you could invalidate any existing sessions of the current user that is logged in. This PHP Secure Login and Registration is a reasonably complete class for creating a login and registration system that you can use in any application regardless if you use or not a framework like CodeIgniter, Zend, Symfony, etc..
This tutorial provides simple examples of how to use its of its core features in any application. You can freely adapt these example scripts to your PHP application. You can download the complete package ZIP archive from the download page or install it with the composer tool using instructions in the same page.
If you have questions or comments you can post a message as comment to this article or post a support request in its support forum. Logout - Ye Lin Aung Logout does not die session Nice code, secure login but insecure config - Shane Hollis Well written but there are a couple of missing security features Email From - Justin Rigsby Is there a way to customize the from email?
