Laravel Routes

Register download routes in routes/web.php:

use Waterloobae\QuizConverter\CanvasQuizGenerator;
use Waterloobae\QuizConverter\MoodleQuizGenerator;
use Waterloobae\QuizConverter\D2LQuizGenerator;
use Waterloobae\QuizConverter\H5PQuizGenerator;
use Waterloobae\QuizConverter\QTIQuizGenerator;

Route::post('/quiz/canvas/download', function(Request $request) {
    $generator = new CanvasQuizGenerator();
    $generator->setQuestions($request->input('questions'));
    return $generator->download();
});

Route::post('/quiz/moodle/download', function(Request $request) {
    $generator = new MoodleQuizGenerator();
    $generator->setQuestions($request->input('questions'));
    return $generator->download();
});

Question Format

Canvas, D2L, and QTI use a simple array format:

$questions = [
    [
        'text'          => 'What is $2 + 2$?',
        'choices'       => ['3', '4', '5', '6'],
        'correct_index' => 1,
        'solution'      => '$2 + 2 = 4$.',
    ],
];

Moodle uses a named answers structure:

$questions = [
    [
        'type'     => 'multiple_choice',
        'question' => 'What is $2 + 2$?',
        'answers'  => [
            ['text' => '3', 'correct' => false],
            ['text' => '4', 'correct' => true],
            ['text' => '5', 'correct' => false],
        ],
        'solution' => '$2 + 2 = 4$.',
    ],
];

H5P uses the same structure as Moodle but with a text key instead of question:

$questions = [
    [
        'type'     => 'multiple_choice',
        'text'     => 'What is $2 + 2$?',
        'choices'  => [
            ['text' => '3', 'correct' => false],
            ['text' => '4', 'correct' => true],
        ],
        'solution' => '$2 + 2 = 4$.',
    ],
];
