System Setup (Installation) and Description for WAMP Server

1. Install WAMP server for PHP and MySQL Download and Follow the Setup Procedure in

http://www.wampserver.com/en/

2. Created a new company database in MySQL (You can use the same SQL script written for MS

SQL Server)

3. Create a basic web application (Web Server with Webpage) using responsive bootstrap HTML

framework

4. Create Stored Procedure in MySQL

5. Manage remaining web application flow in Webserver codes in PHP.

Create a Stored Procedure in MySql first

CREATE PROCEDURE `SP_Insert_NewEmployee`(IN `Fname` VARCHAR(20), IN `Minit` VARCHAR(1),

IN `Lname` VARCHAR(20), IN `Ssn` TEXT, IN `Bdate` DATE, IN Àddress` TEXT, IN `Sex` VARCHAR(1), IN

`Salary` VARCHAR(10), IN `Mssn` VARCHAR(50), IN `Dno` VARCHAR(50))

BEGIN

INSERT INTO `company`.èmployee` (`Fname`, `Minit`, `Lname`, `Ssn`, `Bdate`, Àddress`, `Sex`,

`Salary`, `Super_ssn`, `Dno`) VALUES (Fname,Minit, Lname, Ssn, Bdate, Address, Sex, Salary, Mssn,

Dno);

insert into works_on SELECT Ssn "Ssn", Pnumber, 0 FROM `project` WHERE `Dnum`=Dno;

END

index.php

•its landing page, after basic login check it will redirect to employee.php

employee.php

•on click on "ADD" it will open a new page "add_employee.php" .

add_employee.php

• Page shows all fields to create employee.

•After filling all the detail click on submit button, it will call form submit event and page submit POST data to self.

add_employee.php

•POST data can be checked

•if valid then call SP_Insert_NewEmployee with newly entered data

•if employee addes sussfully page will redirect to "employee.php"
