Task 1: Learner Extracurricular Registration Form
File: task1.php Chapter: 7 Marks: 25
1.1 What does Task 1 require?
Task 1 requires building a PHP web form that collects learner registration data for extracurric-
ular activities, validates that all required fields are completed, and then displays a formatted
registration summary with a calculated total cost.
1.2 What files are involved?
Two files are needed: task1.php (the form and processing logic) and task1.txt (the plain-
text version of the PHP code displayed in an iframe at the bottom of the page). The shared
navigation menu is included via menu.inc.
1.3 What is the complete PHP solution?
The solution below covers the full form structure (GET method), server-side validation, and
the formatted output paragraph with cost calculation.

Listing 1: task1.php — Extracurricular Registration Form
1.4 How does the validation logic work?
The form uses the HTTP GET method so all submitted values appear in the $_GET super-
global. Three conditions are checked before displaying results:
1. The learner_name field must not be empty after trimming whitespace.
2. The grade dropdown must have a selection other than the placeholder.
3. The activities checkbox array must contain at least two elements.
If any condition fails, an error message is shown. If all pass, the registration summary is
echoed using a loop that also accumulates the total payable amount.
Implementation Insight
Free vs Paid Activities: The $activities associative array stores each activity
name as a key and its per-term cost as the value. A cost of zero represents a free activ-
ity. This makes adding or removing activities straightforward because only the array
definition needs updating.
1.5 What does menu.inc contain?
