Overview

The Primary School Management System allows you to add various types of records through dedicated HTML forms. Each form collects specific information and submits it to a PHP script that inserts the data into the database using MySQL.

​
Accessing Add Forms

1

Navigate to the Add menu

From the navigation bar, click on the Add dropdown button to reveal all available record types.
2

Select record type

Choose the type of record you want to add:
  • Student
  • Parent
  • Teacher
  • Class
  • Gym Member
  • Salary
All forms are accessible from the navigation dropdown menu located at the top of every page in the system.

​
Adding a Student

To add a new student to the system, navigate to AddStudent.html from the Add dropdown menu.
1

Fill in student information

The student form requires the following fields:
<form method="post" action="AddStudent.php">
    <label for="Sname">Student Name:*</label>
    <input type="text" required name="Sname">
    
    <label for="Ssurname">Student Lastname:*</label>
    <input type="text" required name="Ssurname">
    
    <label for="Sbirthday">Student Birthday:*</label>
    <input type="date" required max="2023-04-06" name="Sbirthday" />
    
    <label for="Parent_ID">Parent ID:*</label>
    <input type="text" required name="Parent_ID">
    
    <label for="Class_ID">Class ID:*</label>
    <input type="text" required name="Class_ID">
</form>
2

Enter required details

  • Student Name (Sname): First name of the student
  • Student Lastname (Ssurname): Last name of the student
  • Student Birthday (Sbirthday): Date of birth (must be before April 6, 2023)
  • Parent ID (Parent_ID): ID of the associated parent record
  • Class ID (Class_ID): ID of the class the student belongs to
3

Submit the form

Click the Submit button to create the student record.
The system validates that the birthday cannot be later than April 6, 2023. Make sure the Parent ID and Class ID already exist in the database before creating a student record.

​
Backend Processing

When you submit the student form, the AddStudent.php script processes the data: 
if (isset($_POST['submit'])) {
    $Sname = $_POST['Sname'];
    $Ssurname = $_POST['Ssurname'];
    $Sbirthday = $_POST['Sbirthday'];
    $Parent_ID = $_POST['Parent_ID'];
    $Class_ID = $_POST['Class_ID'];

    $send = "INSERT INTO Student1 (Sname,Ssurname,Sbirthday,Parent_ID,Class_ID) 
             VALUES ('$Sname','$Ssurname','$Sbirthday','$Parent_ID','$Class_ID')";
    
    if (mysqli_query($link, $send)) {
        echo "New record created successfully";
    } else {
        echo "Error adding record";
    }
}
The script inserts the data into the Student1 table and displays a success or error message.

Database Connection

All add operations connect to the MySQL database using: 
$link = mysqli_connect(
    "sdb-57.hosting.stackcp.net", 
    "student84-353031351c89", 
    "ua92-studentAc", 
    "student84-353031351c89"
);

if ($link === false) {
    die("Connection failed: ");
}
The system uses the mysqli_connect() function to establish a connection with the MySQL server and returns the connection as an object for all database operations.
