Task 1: Extracurricular Activity Registration Form (25 Marks)

Chapter reference: 7 | Page name: task1.php

This task requires building a PHP web form that registers school learners for extracurricular
activities, validates the submitted data, and displays a registration summary with fee calcula-
tion.

Display Registration Form




User Submits Form (GET)




All fields
filled?


No Yes


Display error: Display registration
“Form is incomplete” summary and total fee


Figure 1: Task 1 – Form Processing Flow



Question 1: How should the HTML form be structured?


The form uses the GET method as required by the assignment. Each field is labelled clearly.
The grade dropdown is populated programmatically using a PHP loop over grades 1 to 7. Six
extracurricular activities are listed as checkboxes: three are free (Soccer, Netball, Choir) and
three are paid (Chess at R150/term, Pottery at R200/term, Golf at R250/term). The form
also includes a text field for the learner’s full name and a submit button.

Key Distinction
The GET method appends form data to the URL as query string parameters. This is
appropriate for non-sensitive, idempotent operations such as a registration lookup. The

POST method sends data in the HTTP request body and is preferred for sensitive data.
This task explicitly requires GET.



Question 2: How should form validation be implemented?


Three conditions must all be satisfied before processing proceeds:

1. The full name field must not be empty.
2. A grade must be selected (not the default placeholder).
3. At least two checkbox activities must be selected.

If any condition fails, an error message is echoed to the page. If all conditions pass, the regis-
tration summary and total fee are displayed below the form.


Question 3: How is the total fee calculated?


The code iterates over the selected activities. Each activity has a predefined cost (R0 for free
activities). The total is accumulated in a variable and displayed using echo formatted with
South African Rand notation.
