Our Database tutorials are up to date and well explained step-by-step using examples so you can learn Database manipulation fast.
Sometimes required to restrict the user to only log in on a single system or a browser at a time.
To prevent the user from login on multiple systems or web browsers you need to generate a token on each successful login attempt.
Need to check the token on each page. If the token does not match then destroy the SESSION and log out the user.
In this tutorial, I show how you can prevent multiple logins of the same user with PHP.
Within the project sometimes requires using multiple MySQL databases. It may be the existing database from another project or the new one.
To handle this with PHP requires to create separate connections for each database and use the connection accordingly while manipulating data in MySQL database.
From cPanel you cannot directly create or upload your database using PHPMyAdmin while making your website live. You need to follow some of the steps like – creating a database, user, etc.
The cPanel gives easy to use interface that makes it easier to manage the database and make it available in the PHPMyAdmin.
In this tutorial, I am assuming that you already have a cPanel enabled web hosting server.
The Codeigniter allows us to perform the database action like – select, insert, update, and delete with the minimal script.
The $this->db->update() method is used for update existing record. It takes table name and an array or object as the parameter.
In the demonstration, I am listing the user’s list with the edit option. Show the update form on edit option-click.
