Thank you, that worked!

Well of course I would validate names and age in a different way, but we have strict lab specifications where all the validation thing must be same as in specification 😂

Hey! So I've encountered some issues with my code. It validates the input. If the input is correct it writes to a file. If not - should display the error message with errors that should be fixed. But it does not display it. I've tried many things to fix it but it just does not work. It refreshes the page and that's all. Can somebody help me with it? Thanks in advance! <html lang="en"> <head> <meta charset="utf-8"> <meta name="author" content="Nikita Z"> <title>LAB 5 - PHP Form</title> </head> <body> <nav> <ul> <li><a href="index.php">Home</a></li> <li><a href="download.php">Download Data</a></li> </ul> </nav> <h1>Registration Form</h1> <form method="post" action="index.php" id="formReserve"> <label for="nameFirst">First Name:</label> <input type="text" id="nameFirst" name="nameFirst" required><br><br> <label for="nameMiddle">Middle Name:</label> <input type="text" id="nameMiddle" name="nameMiddle"><br><br> <label for="nameLast">Last Name:</label> <input type="text" id="nameLast" name="nameLast" required><br><br> <label for="salutation">Salutation:</label> <select id="salutation" name="salutation" required> <option value="Mr.">Mr.</option> <option value="Ms.">Ms.</option> <option value="Mrs.">Mrs.</option> <option value="Sir">Sir</option> <option value="Prof.">Prof.</option> <option value="Dr.">Dr.</option> </select><br><br> <label for="age">Age:</label> <input type="number" id="age" name="age" required min="18" max="98"><br><br> <label for="email">Email:</label> <input type="email" id="email" name="email" required><br><br> <label for="phone">Phone(Including country code):</label> <input type="tel" id="phone" name="phone" required><br><br> <label for="dateArrive">Date of Arrival:</label> <input type="date" id="dateArrive" name="dateArrive" required><br><br> <input type="submit" id="submitReservation" name="submit" value="Submit"> </form> <?php //Set error reporting to all ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); // Define an array to store validation errors $errors = array(); // Check if the form has been submitted if ($_SERVER['REQUEST_METHOD'] === 'POST') { // Validate first name if (isset($_POST['nameFirst']) && !preg_match('/^[a-zA-Z]+$/i', $_POST['nameFirst'])) { $errors[] = 'First name must not contain digits or special characters'; } // Validate middle name if (isset($_POST['nameMiddle'])) { if ($_POST['nameMiddle'] === '') { // Middle name is empty } else if (!preg_match('/^[a-zA-Z]+$/i', $_POST['nameMiddle'])) { $errors[] = 'Middle name must not contain digits or special characters'; } } // Validate last name if (isset($_POST['nameLast']) && !preg_match('/^[a-zA-Z]+$/i', $_POST['nameLast'])) { $errors[] = 'Last name must not contain digits or special characters'; } // Validate salutation $allowedSalutations = array('Mr.', 'Ms.', 'Mrs.', 'Sir', 'Prof.', 'Dr.'); if (isset($_POST['salutation']) && !in_array($_POST['salutation'], $allowedSalutations)) { $errors[] = 'Invalid salutation'; } // Validate age if (isset($_POST['age']) && ($_POST['age'] < 18 || $_POST['age'] > 98)) { $errors[] = 'Age must be between 18 and 98'; } // Validate email if (isset($_POST['email']) && !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) { $errors[] = 'Invalid email address'; } // Validate phone number if (isset($_POST['phone']) && !preg_match('/^(\+?\d{1,3}[\s-]?)?\(?\d{3}\)?[\s.-]?\d{3}[\s.-]?\d{4}$/', $_POST['phone'])) { $errors[] = 'Invalid phone number'; } // Validate arrival date if (isset($_POST['dateArrive'])) { $minDate = new DateTime('2023-01-01'); $maxDate = new DateTime('2033-01-01'); $arrivalDate = DateTime::createFromFormat('Y-m-d', $_POST['dateArrive']); if (!$arrivalDate || $arrivalDate < $minDate || $arrivalDate > $maxDate) { $errors[] = 'Invalid arrival date'; } } // If there are no validation errors, store the form data if (empty($errors)) { // Define the name of the CSV file $filename = 'data.csv'; // Define the data to be written to the CSV file $data = array( $_POST['nameFirst'], $_POST['nameMiddle'], $_POST['nameLast'], $_POST['salutation'], $_POST['age'], $_POST['email'], $_POST['phone'], $_POST['dateArrive'], ); // Convert the data array to a string $data_string = implode(";", $data) .
