Numbers and String Concatenation Create a PHP form that allows input for an individual and displays the information on a subsequent page upon submission. The form should include a drop down field with each family or friend from the tree assignment and fields that match the web pages for each individual in the family or friend tree assignment. For example, fields could include career, favorite book, and interests. Use proper form validation. Upon submission of the form, the user should be transferred to the appropriate individual’s web page based upon the drop down selection. The web page of each friend or family member should now display updated results from the information entered into the form. For example, if a new goal was written in the goals field on the form, it should be appended to the goal’s section of the family or friend’s page.

This paper discusses the development of a PHP-based web application designed to collect, validate, and display information about family and friends dynamically. The application comprises a form interface that allows users to input details about an individual, such as career, favorite book, interests, and goals. The form includes a drop-down menu listing various family or friends from a predefined tree assignment. Upon submission, the application ensures proper validation, redirects users to the relevant individual's web page, and updates the displayed information seamlessly.

Introduction

Creating interactive and dynamic web pages is fundamental in modern web development. PHP, a server-side scripting language, is widely used for building such applications. In this context, the goal is to develop a PHP form that collects personal information about family or friends, validates the input, and then displays the updated information on the individual’s dedicated web page. This approach facilitates real-time updates and ensures that data remains accurate and comprehensive.

Design and Implementation of the PHP Form

The core component of this system is a PHP form that captures various details about a person. The form includes:

  • A drop-down menu that lists individuals from a predefined family or friend tree.
  • Input fields for career, favorite book, interests, and goals.

Proper validation is essential to ensure data integrity. Validation includes checking for empty fields, correct data formats, and potentially malicious inputs. PHP's filter_input() and validation functions are employed to enforce these standards.

Data Handling and Storage

The information entered in the form is stored either temporarily in sessions or persistently in a database. For simplicity and demonstration purposes, files can also be used to store individual data. When a user submits the form, the script retrieves the current data for the selected individual, appends or updates the information, and then saves it back.

Navigation and Dynamic Content Update

After processing the form data, the application redirects the user to the specific web page corresponding to the selected individual via PHP header redirects. On the individual's page, the latest information, including new goals or interests, is displayed dynamically by reading the stored data. This ensures each person's page reflects current data without manual updates.

Sample PHP Code for the Form

<?php


$individuals = ['Alice', 'Bob', 'Charlie', 'Diana'];


if ($_SERVER['REQUEST_METHOD'] === 'POST') {


$name = $_POST['name'];


$career = trim($_POST['career']);


$favorite_book = trim($_POST['favorite_book']);


$interests = trim($_POST['interests']);


$goals = trim($_POST['goals']);


// Basic validation


if (empty($name) || empty($career) || empty($favorite_book) || empty($interests) || empty($goals)) {


echo "Please fill in all fields.";


} else {


// Store data in a file or database


$data = [


'career' => $career,


'favorite_book' => $favorite_book,


'interests' => $interests,


'goals' => $goals


];


file_put_contents("data/". strtolower($name). ".json", json_encode($data));


// Redirect to individual's page


header("Location: " . strtolower($name) . ".php");


exit();


}


}


?>

Personalized Individual Web Pages

Each individual’s page, e.g., alice.php, reads its specific data file and displays the uploaded information. The code reads the JSON data stored previously and dynamically constructs sections to present career, favorite book, interests, and goals. When new goals or interests are added via the form, they are appended to the relevant section to reflect updates seamlessly.

Updating and Displaying Data

The process involves reading stored data, parsing it, and generating HTML content dynamically, thus enabling the display of the most recent user inputs. For example, each individual page can include PHP code such as:

<?php


$dataFile = 'data/alice.json';


if (file_exists($dataFile)) {


$jsonData = json_decode(file_get_contents($dataFile), true);


} else {


$jsonData = [


'career' => '',


'favorite_book' => '',


'interests' => '',


'goals' => ''


];


}


?>


About Alice


Career: <?php echo htmlspecialchars($jsonData['career']); ?>


Favorite Book: <?php echo htmlspecialchars($jsonData['favorite_book']); ?>


Interests: <?php echo htmlspecialchars($jsonData['interests']); ?>


Goals


<?php echo nl2br(htmlspecialchars($jsonData['goals'])); ?>

Conclusion

This PHP-based application facilitates interactive data collection and display regarding family and friends. By validating user inputs, dynamically updating individual pages, and storing data persistently, it demonstrates a practical approach to managing personal data in web development. Such an application can be expanded with additional features like user authentication, editing capabilities, or database integration to enhance functionality and security.
