Bootgrid.php(Controller)


First We have to make Bootgrid.php Controller under application/controllers folder. This class is mainly used for handle http request for perform Insert, Update, Delete and Read data Request. In this class, you can find following function.


index() - This is root function for this class, when in browser, we have write base url with this class then this function has been called. This function has load bootgrid.php view as output on browser.


fetch_data() - This function is received Ajax request from Bootgrid plugin for fetch data from mysql data. This function will convert data into Array format, and send to Bootgrid Ajax request in json string formate.


action() - This function is used for insert or add into mysql table using ajax. Because this function has received ajax request for insert data into mysql table.


fetch_single_data() - This function mainly fetch particular employee details based on value of employee id. This is for edit existing employee details.

delete_data() - This function is used for handle Ajax delete data request from jQuery Bootgrid Plugin in Codeigniter.

bootgrid.php(Views)


View file in Codeigniter framework is used for display HTML output on Web page. This bootgrid.php view file you can find under application/views folder.
