Mokey Nepal: CRUD OPERATIONS IN OOP AND PHP PDO USING BOOTSTRAP FRAMEWORK.

CRUD OPERATIONS IN OOP AND PHP PDO USING BOOTSTRAP FRAMEWORK.

Hello Guys! This Tutorial Is About CRUD OPERATIONS IN OOP AND PHP PDO USING BOOTSTRAP FRAMEWORK WITH PAGINATION.

This tutorial is same like our previous tutorial that we have done simply just for fast learning of php pdo and oop menthod for add, edit and delete.

For Database Creation and previous tutorial, go to this http://mokeynepal.blogspot.com/2017/03/add-edit-delete-and-display-using-php.html .

In this tutorial i have just added bootstrap table for displaying mysql data, bootstrap modal for Add and delete operations,bootstrap forms and inputs. And Successfull and warning messages alert in bootstrap alerts, while adding deleting and updating operations are done, This looks Very Nice and flexible bt not like before.

Bootstrap Framework is a free framework with css and jquery combination. Its a Top framework for mobile friendly responsive web design layouts.

You Can download Bootstrap from here :getbootstrap.com

I am not going to describe whole coding of php pdo and oop here in this tutorial.

After downloading bootstrap simply include these files as like below inside head tags of your php framework...

CHANGES OF CRUD OPERATIONS IN OOP AND PHP PDO NOW USING BOOTSTRAP FRAMEWORK FILES ARE HERE LIKE THIS.

db.php

<?php
$DBhost = "localhost";
$DBuser = "root";
