In your form handling code, you're calling `incude('');`, which is a typo. It should be `include('');` but I don't think it's meant to be there. This line is not needed, so you should just remove it.

Hi, I am having issues with this cbt project whereby my questions are selected 5 per page and when the user click on NEXT, the first page selected radio button option should be saved so that when the user click on previous button, he should be able to see the selected options. But I have been finding difficult to do. And I don't think it is right to create another table again to store the user answers because in each subjects, there are more than 15 questions.

Hi, I am currently using a shared hosting provider that includes cPanel, MySQL database support, and phpMyAdmin, but I've been experiencing frequent fluctuations and downtime. I'm looking for a more stable and reliable hosting solution that is also cost-effective. Here are my requirements: cPanel or Equivalent: I need a control panel for easy website and server management. MySQL Database Support: Reliable MySQL database hosting is essential. phpMyAdmin: A web-based interface for managing MySQL databases. Uptime and Stability: A hosting provider known for good uptime and stability. Cost-Effective: Affordable pricing, ideally comparable to shared hosting costs. Additional Features: Any additional features like automatic backups, SSL certificates, and support for PHP applications would be a plus. Could you please recommend any hosting providers that meet these criteria? Personal experiences and specific plans that you have had success with would be greatly appreciated. Thank you for your assistance!

You'll need to install Composer on your web server. Composer is a dependency manager for PHP that allows you to easily manage libraries and packages. Go to the https://getcomposer.org/, download the Installer for Composer depending on your OS. Open the downloaded Composer-Setup.exe (Windows OS as an example) file. Follow the prompts in the installation wizard. Make sure to select the option to add Composer to the system PATH during installation. Verify Installation: Open Command Prompt. Type composer and press Enter. You should see the Composer version and available commands, confirming that Composer is installed and accessible globally. Open Command Prompt and navigate to your project directory: cd path\to\your\project\directory Use Composer to install the PhpSpreadsheet library by creating a composer.json file and running composer install. Include the Composer autoload file in your PHP script and use PhpSpreadsheet to read your Excel files.

To read .xlsx files using PHP 8, you can use the PhpSpreadsheet library. It's the successor to PHPExcel and fully supports PHP 8. You can run this command "composer require phpoffice/phpspreadsheet" and Once you have PhpSpreadsheet installed, you can use it to read .xlsx files. Here's a basic example: <?php require 'vendor/autoload.php'; use PhpOffice\PhpSpreadsheet\IOFactory; try { $spreadsheet = IOFactory::load('path/to/your/file.xlsx'); $sheet = $spreadsheet->getActiveSheet(); // Get the highest row and column numbers referenced in the worksheet $highestRow = $sheet->getHighestRow(); // e.g. 10 $highestColumn = $sheet->getHighestColumn(); // e.g 'F' // Iterate over each row in the worksheet in turn for ($row = 1; $row <= $highestRow; $row++) { $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE); print_r($rowData); } } catch (Exception $e) { echo 'Error loading file: ', $e->getMessage(); } ?>

Thank you so much for the support and all the guidance. Though, I have solved the problem by using instascan instead of the previous quagga and html5 qrcode. But getting worked is nothing but to take to practices all the programming advices you have highlighted which is very essential. I cannot but to always thank you all in this forum for your help and I can say ever since I have joined this forum, I have never for once regret that. You are all amazing. Cheers

I appreciate you, but that does not give me the options. Though, I pending the project for now as it is taking more time and still no solution. I will still get back on it.

Thank you sir. Can you please explain this further. In my previous and abandoned work, I do upload images inside the Microsoft word but and also wrote a script to identify that, but it doesn't work. It only captured the text documents.

Dear gurus in the house, I am trying to create an online CBT examination such that admin should be able to upload questions directly from Ms Word which might involve equations, graphs, formatting like bold, italicize and other features. But I am very confused regards this because I am not a guru and I don't want to use ready made software like moodle, but I want to design mine from scratch as a web application. I have used pho with no framework and was able to extract questions from Microsoft word with auto grading but this is not extracting the images, equations and the formats like bold. I stumbled from there again to use python with fastapi but all to no avail. Please guru in the house help me by putting me through on the model to use to achieve this. The questions will uploaded based on class like Basic 1, 2 and so on. I know you are all intelligent and here is a forum that solve problems.

Thanks so much.

Hi, I am a newbie to Laravel and trying to familiarize myself with it, so I am starting with a CBT project and when I navigate to http://127.0.0.1:8000/, it keeps taking me to laravel news page which differ from my project page. Here is my web.php <?php use Illuminate\Foundation\Application; use Illuminate\Support\Facades\Route; use Inertia\Inertia; use App\Http\Controllers\QuestionController; Route::get('questions', [QuestionController::class, 'index'])->name('questions.index'); Route::get('questions/create', [QuestionController::class, 'create'])->name('questions.create'); Route::post('questions', [QuestionController::class, 'store'])->name('questions.store'); Route::get('/', function () { return Inertia::render('Welcome', [ 'canLogin' => Route::has('login'), 'canRegister' => Route::has('register'), 'laravelVersion' => Application::VERSION, 'phpVersion' => PHP_VERSION, ]); }); Route::middleware([ 'auth:sanctum', config('jetstream.auth_session'), 'verified', ])->group(function () { Route::get('/dashboard', function () { return Inertia::render('Dashboard'); })->name('dashboard'); }); And here is the page I keeps loading to Please advise and if I could get a comprehensive tutorial that will guide me to pass the hurdles. I find it a bit difficult but with its authentication built in, it is okay.

I understand your point, for instance storing names again in the invoice table when the names are available in the student table is like exhausting more spaces and I don't think it can last if the storage space is not much, it can crash. You and @Barand have contributed tremendously. I am not yet an expert like you all, but I believe in consistent practicing.

The fee is not constant, it do change, and for instance, a student who lives in hostel (Boarder) might decide he want to be coming from home as Day student, and a Day student can even decide he want to stay in hostel for a week maybe for a purpose known to him, and this do cause confusion if there is fixed price. Also, some parents might decide they want to pay less on any of the fee either IGCSE, Sports or anything. That is why I think entering the fee manually could be okay to handle such scenario. Some students are on scholarship where tuition will be free, but they will pay for other expenses and some on free feeding, and so on. And School fee may change anytime.

Thanks @BarandCan you please give me more hints on this?

total_fee_payable is still not calculating well but calculated_total_fee calculated well as required. I want this calculated as: total_fee_payable = (fee_amount + total_fee_from_items) - (total_fee_from_items + discount_amount) I have tried many approach but not working, it is not adding the amounts in the items_table to the total_fee_payable in the invoices table. From the sample query below: From items_table: invoice_id 118 should be added to the invoices id total_fee_payable CREATE TABLE `invoices` ( `id` int(11) NOT NULL, `student_id` int(11) NOT NULL, `semester_id` int(11) NOT NULL, `student_name` varchar(255) NOT NULL, `current_class_id` varchar(255) DEFAULT NULL, `fee_description` varchar(255) NOT NULL, `fee_amount` decimal(10,2) NOT NULL, `less_fee_description` varchar(255) DEFAULT NULL, `less_fee_amount` decimal(10,2) DEFAULT NULL, `discount_amount` decimal(10,2) DEFAULT NULL, `total_fee_payable` decimal(10,2) NOT NULL, `invoice_number` varchar(50) NOT NULL, `status` enum('PAID','PENDING') DEFAULT 'PENDING', `created_at` timestamp NOT NULL DEFAULT current_timestamp(), `updated_at` timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp() ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci; -- -- Dumping data for table `invoices` -- INSERT INTO `invoices` (`id`, `student_id`, `semester_id`, `student_name`, `current_class_id`, `fee_description`, `fee_amount`, `less_fee_description`, `less_fee_amount`, `discount_amount`, `total_fee_payable`, `invoice_number`, `status`, `created_at`, `updated_at`) VALUES (118, 678, 16, 'AU', 'Year 11', 'school fee ', '50000.00', 'hg', '1000.00', '1000.00', '48000.00', 'B/2024/67982', 'PENDING', '2024-02-03 00:12:06', '2024-02-03 00:12:06'); -- -- Triggers `invoices` -- DELIMITER $$ CREATE TRIGGER `calculate_total_fee_payable_update` BEFORE UPDATE ON `invoices` FOR EACH ROW BEGIN SET NEW.total_fee_payable = ( SELECT COALESCE(SUM(fee_amount), 0) FROM items_table WHERE invoice_id = NEW.id ) + NEW.fee_amount - COALESCE((NEW.less_fee_amount + NEW.discount_amount), 0); END $$ DELIMITER ; ALTER TABLE `invoices` ADD PRIMARY KEY (`id`), ADD KEY `semester_id` (`semester_id`), ADD KEY `fk_invoices_student` (`student_id`); -- -- AUTO_INCREMENT for dumped tables -- -- -- AUTO_INCREMENT for table `invoices` -- ALTER TABLE `invoices` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=119; -- -- Constraints for dumped tables -- -- -- Constraints for table `invoices` -- ALTER TABLE `invoices` ADD CONSTRAINT `fk_invoices_student` FOREIGN KEY (`student_id`) REFERENCES `student` (`id`), ADD CONSTRAINT `invoices_ibfk_1` FOREIGN KEY (`semester_id`) REFERENCES `semester` (`id`); COMMIT; CREATE TABLE `items_table` ( `id` int(11) NOT NULL, `invoice_id` int(11) NOT NULL, `fee_description` varchar(255) NOT NULL, `fee_amount` decimal(10,2) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci; INSERT INTO `items_table` (`id`, `invoice_id`, `fee_description`, `fee_amount`) VALUES (16, 118, 'sports', '5000.00'), (17, 118, 'club', '5000.00'); ALTER TABLE `items_table` ADD PRIMARY KEY (`id`), ADD KEY `fk_items_invoice` (`invoice_id`); -- -- AUTO_INCREMENT for dumped tables -- -- -- AUTO_INCREMENT for table `items_table` -- ALTER TABLE `items_table` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=18; -- -- Constraints for dumped tables -- -- -- Constraints for table `items_table` -- ALTER TABLE `items_table` ADD CONSTRAINT `fk_items_invoice` FOREIGN KEY (`invoice_id`) REFERENCES `invoices` (`id`); COMMIT;

I realized my mistake. You elders are all amazing. I don't know which one I should marked as solutions but you all did very excellent and expedite my problem to be solved. However, I am still working on it as this is just a section and when I am finally done with this, I have a vital question to ask on PHP as someone told me when I went for an interview that in the next two years, PHP will be outdated and not sellable in the market again. error_reporting(E_ALL); ini_set('display_errors', 1); // Check if the form data is set if ( isset($_POST['semesterId']) && isset($_POST['studentName']) && isset($_POST['feeDescription']) && isset($_POST['feeAmount']) && isset($_POST['lessFeeDescription']) && isset($_POST['lessFeeAmount']) && isset($_POST['discountAmount']) && isset($_POST['invoiceNumber']) //I think the problem is adding the grandTotal variable here ) { // Get form data $semesterId = $_POST['semesterId']; $studentName = $_POST['studentName']; $feeDescription = $_POST['feeDescription']; $feeAmount = $_POST['feeAmount']; $lessFeeDescription = $_POST['lessFeeDescription']; $lessFeeAmount = $_POST['lessFeeAmount']; $discountAmount = $_POST['discountAmount']; $invoiceNumber = $_POST['invoiceNumber']; // Calculate grand total $grandTotal = $feeAmount - ($lessFeeAmount + $discountAmount); // Additional validation if (empty($_POST['studentName']) || empty($_POST['feeDescription']) || empty($_POST['feeAmount'])) { header('HTTP/1.1 400 Bad Request'); echo 'Invalid form data. Please fill out all required fields.'; exit; } try { $query = "INSERT INTO invoices (semester_id, student_name, fee_description, fee_amount, less_fee_description, less_fee_amount, discount_amount, invoice_number, total_fee_payable) VALUES (:semesterId, :studentName, :feeDescription, :feeAmount, :lessFeeDescription, :lessFeeAmount, :discountAmount, :invoiceNumber, :totalFeePayable)"; // Prepare the query $stmt = $pdo->prepare($query); // Bind parameters $stmt->bindParam(':semesterId', $semesterId, PDO::PARAM_INT); $stmt->bindParam(':studentName', $studentName, PDO::PARAM_STR); $stmt->bindParam(':feeDescription', $feeDescription, PDO::PARAM_STR); $stmt->bindParam(':feeAmount', $feeAmount, PDO::PARAM_STR); $stmt->bindParam(':lessFeeDescription', $lessFeeDescription, PDO::PARAM_STR); $stmt->bindParam(':lessFeeAmount', $lessFeeAmount, PDO::PARAM_STR); $stmt->bindParam(':discountAmount', $discountAmount, PDO::PARAM_STR); $stmt->bindParam(':invoiceNumber', $invoiceNumber, PDO::PARAM_STR); $stmt->bindParam(':totalFeePayable', $grandTotal, PDO::PARAM_STR); // Bind grandTotal to the total_fee_payable column

I am on it right now, could you believe I only modified the save_invoice.php script and got working, but I have removed all the calculations in javascript and still not working until now, but I want to retrace my steps again. You guys (no, I won't call you guys, but elders) are amazing and wonderful family. I am still on it, and will surely be here when there is hurdles again. Thanks for now.
