A view is an HTML or PHP file in the CodeIgniter which is used to display output on the browser.
From where the user can interact with the website and perform actions.
Views are loaded by the controller and one view can load other views on the page.
In this tutorial, I create a simple demonstration where I create a view and load it from the controller.
CSV files are easier to maintain and can be used for export and import data in the web application.
For data import first, need to allow the users to browse and upload the file. In CodeIgniter, there is upload library available that makes it easier to handle file uploads.
In this tutorial, I show how you can import data of CSV file in the MySQL database table in the CodeIgniter 3 project.
CSV (Comma Separated Values ) is the most popular file format for data import and export within the project.
In PHP for creating CSV file, you can either use fputcsv() method or directly write the comma-separated content on the file.
In this tutorial, I will show you how you can export MySQL data in CSV file format in your CodeIgniter 3 project.
Dynamically dependent dropdown commonly seen in the country, state, and city selection on the webpage. The data on the child element changes according to the value of the parent element.
The process follows the same way if there are more than 2 dropdown elements.
To do this you can either use only PHP or jQuery AJAX.
In this tutorial, I am using jQuery AJAX to make dynamic dependent dropdown in CodeIgniter.
