Our PHP tutorials are up to date and well explained step-by-step using live examples so you can learn PHP fast and you can download scripts.
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.
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 their id, product details, etc.
In the demonstration, I am using jQuery UI to display a suggestion list and fetch details using PHP from the MySQL database table when a value from the suggestion list gets selected.
If you know how to send jQuery AJAX request in Core PHP then it is simpler for you to do it in CodeIgniter.
In CodeIgniter, you can use the controller and model to handle AJAX call instead of creating a separate file. Make AJAX call either from the view or external script file.
In this tutorial, I am creating a simple example to demonstrate the AJAX calling in CodeIgniter 3.
