Summary

This video tutorial provides a step-by-step guide on how to display data from a database using CodeIgniter. It covers the configuration of essential files like autoload.php and database.php, setting up a database, and creating a controller and model in CodeIgniter. The tutorial also demonstrates how to create a view to display data from the database in a table format. The video concludes with a promise to cover updates and deletions in a future tutorial.

Takeaways

• 💻 The video explains how to display data using CodeIgniter, a popular PHP framework.
• 🔧 The first step involves preparing the environment by downloading and extracting the necessary files.
• 📝 Configuration of the autoload file is crucial, where you need to load libraries like 'database'.
• 📂 The configuration process includes setting up important files such as 'autoload.php' and 'config.php'.
• 🗄️ Database setup involves configuring the database file with the appropriate credentials like username, password, and database name.
• ⚙️ A controller named 'Product' needs to be created in the application/controllers directory.
• 💻 The next step is creating a model file 'Product_model' in the application/models directory to handle database interactions.
• 🖥️ The view file 'product_view.php' should be created in the application/views directory to display data from the database.
• 📊 The view file includes a table structure to display data retrieved from the model.
• 🛠️ Finally, a database and table are created with columns such as 'product_code', 'product_name', and 'product_price', followed by running the CodeIgniter application to view the data.
