About the Online Examination System

This Online Examination System Project has been developed with the following:

  • XAMPP v3.3.0
  • PHP
  • CodeIgniter
  • MySQL Database
  • HTML
  • CSS
  • JavaScript
  • Ajax
  • jQuery
  • Bootstrap
  • Font Awesome
  • AdminLTE
  • DataTables

The Online Examination System Project in PHP Codeigniter requires valid and registered users to gain access to the system’s features and functionalities. This application has three different user roles: Administrator, Lecturer/Faculty, and Student. Each of these roles comes with distinct restrictions and permissions.

The Administrator User holds the privilege of accessing and managing all administrative or managerial features and functionalities. They can also manage the list of system users. Administrators are responsible for adding information about faculty and students to the system. They are also the ones who can grant user access to both Lecturers and Students. Additionally, they have the privilege to access Exam Results, Add Questions for Lecturers, and Clear all data in the database.

The Lecturer or Faculty member has limited access to features and functionalities. They can add questions for the classes or courses they are handling. Lecturers have the privilege to create or conduct exam sets. They can create a new exam with relevant information such as the Exam Title and Schedule. Faculty members can also view and print Exam Results per Exam Set. They have access to view student result information for each exam set.

The Student user has the fewest features and functionalities within the system. Student users’ primary purpose for accessing the system is to take exams created by their faculties or lecturers. They can only take the examination if it is still available and only once. Each exam set has a timer set by the Lecturer, which only allows them to finish the exam within a certain time duration. If the countdown or timer reaches zero and the student has not finished taking the exam, the system will automatically submit the student’s completed answers.

Invoice System using PHP Free Source Code

Introduction

This is a PHP project that I’d developed called Invoice System. This is a simple OOP PHP project that can help some companies to manage their invoices. The system handles invoices for both selling products and services. This system can help other programmers especially those who are new to PHP language to learn some techniques and understand how to build an Invoice System in the said programming language.

About the Invoice System

The Invoice System was developed using PHP/OOP, MySQL Database, HTML5, CSS, Javascript (jQuery and Ajax), and Bootstrap. The system stores the list of categories, products, services, and invoices. The invoices that will be store or generated in this system has 2 types which are the product invoice and service invoice. The system automatically generates a random invoice code but also editable and has a validation to check the code availability. After the invoice is saved, then a new window will pop up that contains the printable generated invoice. The dashboard displays the summary of the list stored inside the database. When listing the items of products or services in creating an invoice, the system has error trapping features to prevent human errors to result in system errors.

Establish the database connection in PHP so that you can insert the data with the Razorpay payment id.

Create a table in your database as shown below

DDL information of the table

CREATE TABLE razorpay_payment (

paid_on datetime NOT NULL,
PRIMARY KEY (id)
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Create a file process_payment.php to submit the payment details inside the database after successful payment.

            rzp1.open();
            e.preventDefault();
        }
    }
</script>

Explanation of the above code:-

  • As soon as the form is submitted, we will get the input values using jquery and pass them to the options variable along with the key ID generated from the Razorpay dashboard.
  • When you pass the input values using jquery then do not forget to multiply the amount by 100 because the currency is INR which means you are putting the amount as paisa which is why you need to multiply by 100.
  • Now, you will see a Razorpay interface after giving the phone number and email as shown below. Here you can view various options for payments.

Now, inside the handler function, if you console the response then you will see the response values as shown below. Note that when you console then comment on the ajax request otherwise you can not see the response on the console.

Now we will use the razorpay_payment_id shown on the console and send it with the amount and payee name in the ajax request to the URL: process_payment.php.

Now, in the process_payment.php file, include your database connection file (dbconnect.php) as shown below

<?php
$servername='localhost';
$username="root";
$password="";
try
{
    $con=new PDO("mysql:host=$servername;dbname=myproject_db",$username,$password);
    $con->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
    //echo 'connected';
}
catch(PDOException $e)
{
    echo '<br>'.$e->getMessage();
}
?>

Now, inside the process_payment.php, get the razorpay_payment_id and other data sent from the ajax request and save them in the MySQL database as shown below

<?php
//connect the database
include 'dbconnect.php';
 
//get the payment details from payment page
 
if(isset($_POST['payment_id']) && isset($_POST['amount']) && isset($_POST['name']))
{
    $paymentId = $_POST['payment_id'];
    $amount = $_POST['amount'];
    $name = $_POST['name'];
 
    //insert data into database
    $sql="INSERT INTO razorpay_payment(name,amount,payment_status,payment_id)VALUES('$name','$amount','paid','$paymentId')";
    $stmt=$con->prepare($sql);
    $stmt->execute();
}
?>

Now, inside the success function, you can redirect to a thank you page after successful payment as shown below.

window.location.href = 'thank_you.php';
