You can use jQuery AJAX to autocomplete data on the single or multiple elements when the user search or select value from an element.

It is a better way to allow the users to easily search for data in existing records and get required information e.g. get student details by its id, product details, etc.

In the demonstration, I am using jQuery UI to display suggestion list and fetch details using PHP from the MySQL database table when a value from the suggestion list is gets selected.

The autocomplete functionality shows the suggestion list according to the entered value. The user can select a value from the list.

With jQuery UI you can easily add autocomplete widget on the input element. Navigate to the suggestion list either by mouse or keyboard arrow keys.

It has the various options that allow us to customize the widget.

You can fix the suggestion source value while initializing in this case whenever the user typed any character then it searches the value within the given source value or you can make it dynamic with AJAX.

In the demonstration, I am implementing this on an element which shows the user’s name list according to the entered value with AJAX.

Codeigniter is a lightweight PHP-based framework to develop the web application. It is based on MVC (Model View Controller) pattern.

  • The model handles the data processing – Return data, Insert, Update, or delete records from Database Table.
  • The view displays the final output.
  • The controller manages the Model and view. It handles the users’ inputs.

In this tutorial, I cover basis about Codeigniter.
