CSV is a widely used format for exchanging data between applications.
The database and data dumps should be in a proper format to import data smoothly and without any issue.
In this tutorial, I show how you can import CSV file data in the MySQL database in the CodeIgniter 4 project.
CodeIgniter 4 is a PHP framework that makes web application development simpler. A common task in this field is uploading image files and displaying previews of those images. This article explains how to accomplish the task in CodeIgniter 4 while ensuring security by utilizing a CSRF token.
Many websites, such as social media platforms, e-commerce sites, and content management systems have a core feature of uploading image files. Offering users the flexibility to upload images enhances their overall experience and contributes to more appealing and vibrant content.
Implementing security measures is crucial when developing upload functionality for web applications. Cyber-attacks such as CSRF can have severe consequences, but luckily, CodeIgniter 4 includes built-in protection against this threat, adding an extra layer of security to our image upload system. This feature works by generating CSRF tokens that validate authorized requests and reject malicious ones during the transfer of information. By using CodeIgniter’s CSRF protection, we can maintain the integrity and safety of our system while enabling seamless file transferring capability.
Throughout this article, we will guide you step by step on how to configure CSRF protection, create an upload form, handle the image upload process, and display image previews. By following these instructions, you will be equipped with the knowledge to implement secure image upload and preview functionality in your CodeIgniter 4 applications.
Cross-Site Request Forgery (CSRF) requests are a type of malicious exploit whereby unauthorized commands are performed on behalf of an authenticated user.
CodeIgniter 4 provides protection from CSRF attacks. But it is not enabled by default same as CodeIgniter 3.
The token is generated for each user and it is managed by CodeIgniter to verify the user request.
In this tutorial, I show how you can enable CSRF protection and send AJAX request with CSRF token in the CodeIgniter 4 project.
Modern web applications often involve working with databases to store and manage data. CRUD operations (Create, Read, Update, Delete) form the foundation of interacting with a database.
These operations allow users to create new records, retrieve existing data, update information, and delete entries when necessary. In the context of web development, frameworks provide a structured approach to handle these operations efficiently.
This article is a comprehensive guide on implementing CRUD operations in CodeIgniter 4. It covers how to perform Create, Read, Update, and Delete operations using the framework’s conventions and components.
