You can install the package via Composer:
composer require harishdurga/laravel-quiz- Laravel Version: 9.X
- PHP Version: 8.X
php artisan vendor:publish --provider="Harishdurga\LaravelQuiz\LaravelQuizServiceProvider"If you are updating the package, you may need to run the above command to publish the vendor files. But please take a backup of the config file. Also, run the migration command to add new columns to the existing tables.
$computer_science = Topic::create([
'name' => 'Computer Science',
'slug' => 'computer-science',
]);$algorithms = Topic::create([
'name' => 'Algorithms',
'slug' => 'algorithms'
]);
$computer_science->children()->save($algorithms);A seeder class QuestionTypeSeeder will be published into the database/seeders folder. Run the following command to seed question types.
php artisan db:seed --class=\\Harishdurga\\LaravelQuiz\\Database\\Seeders\\QuestionTypeSeederCurrently, this package is configured to only handle the following types of questions
multiple_choice_single_answermultiple_choice_multiple_answerfill_the_blank
Create a QuestionType:
QuestionType::create(['name'=>'select_all']);Though this package provides three question types you can easily change the method that is used to evaluate the answer. You can do this by updating the get_score_for_question_type property in config file.
'get_score_for_question_type' => [
1 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::get_score_for_type_1_question',
2 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::get_score_for_type_2_question',
3 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::get_score_for_type_3_question',
4 => 'Your custom method'
]But your method needs to have the following signature
/**
* @param QuizAttemptAnswer[] $quizQuestionAnswers All the answers of the quiz question
*/
public static function get_score_for_type_3_question(QuizAttempt $quizAttempt, QuizQuestion $quizQuestion, array $quizQuestionAnswers, $data = null): float
{
// Your logic here
}If you need to pass any data to your method then you can pass it as the last $data parameter. When you call the calculate_score() method of QuizAttempt then you can pass the data as the parameter.
$question_one = Question::create([
'name' => 'What is an algorithm?',
'question_type_id' => 1,
'is_active' => true,
'media_url' => 'url',
'media_type' => 'image'
]);$question_type->questionsQuestion::hasOptions()->get()$question->topics()->attach([$computer_science->id, $algorithms->id]);$question_two_option_one = QuestionOption::create([
'question_id' => $question_two->id,
'name' => 'array',
'is_correct' => true,
'media_type'=>'image',
'media_url'=>'media url'
]);$question->options$quiz = Quiz::create([

'media_url'=>'',
'media_type'=>'',
'negative_marking_settings'=>[
'enable_negative_marks' => true,
'negative_marking_type' => 'fixed',
'negative_mark_value' => 0,
]
]);$quiz->topics()->attach([$topic_one->id, $topic_two->id]);Topics can be attached to a quiz or a question. Questions can exist outside of the quiz context. For example, you can create a question bank which you can filter based on the topics if attached.
By default negative marking is enabled for backward compatibility. You can disable it by setting the enable_negative_marks to false. Two types of negative marking are supported(negative_marking_type). fixed and percentage. Negative marking value defined at question level will be given precedence over the value defined at quiz level. If you want to set the negative marking value at quiz level, set the negative_mark_value to the value you want to set. If you want to set the negative marking value at question level, set the negative_marks of QuizQuestion to your desired value. No need to give a negative number instead the negative marks or percentage should be given in positive.

[
'quiz_attempt_id' => $quiz_attempt->id,
'quiz_question_id' => $quiz_question->id,
'question_option_id' => $question_option->id,
]
);A QuizAttemptAnswer belongs to QuizAttempt,QuizQuestion and QuestionOption
$quiz_attempt->calculate_score()In case of no answer found for a quiz question which is not optional, a negative score will be applied if any.
$question->correct_optionsReturn a collection of QuestionOption.
public function correct_options(): Collection
{
return $this->options()->where('is_correct', 1)->get();
}Please refer to unit and features tests for more understanding.
Instead of getting total score for the quiz attempt, you can use QuizAttempt model's validate() method. This method will return an array with a QuizQuestion model's
id as the key for the assoc array that will be returned.
Example:
$quizAttempt->validate($quizQuestion->id); //For a particular question
$quizAttempt->validate(); //For all the questions in the quiz attempt
$quizAttempt->validate($quizQuestion->id,$data); //$data can any type
[
1 => [
'score' => 10,
'is_correct' => true,
'correct_answer' => ['One','Five','Seven'],
'user_answer' => ['Five','One','Seven']
],
2 => [
'score' => 0,
'is_correct' => false,
'correct_answer' => 'Hello There',
'user_answer' => 'Hello World'
]
]To be able to render the user answer and correct answer for different types of question types other than the 3 types supported by the package, a new config option has been added.
'render_answers_responses' => [
1 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::renderQuestionType1Answers',
2 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::renderQuestionType2Answers',
3 => '\Harishdurga\LaravelQuiz\Models\QuizAttempt::renderQuestionType3Answers',
]By keeping the question type id as the key, you can put the path to your custom function to handle the question type. This custom method will be called from inside the
validate() method by passing the QuizQuestion object as the argument for your custom method as defined in the config.
Example:
public static function renderQuestionType1Answers(QuizQuestion $quizQuestion,QuizAttempt $quizAttempt,mixed $data=null)
{
/**
* @var Question $actualQuestion
*/
$actualQuestion = $quizQuestion->question;
$answers = $quizQuestion->answers->where('quiz_attempt_id', $quizAttempt->id);
$questionOptions = $actualQuestion->options;
$correctAnswer = $actualQuestion->correct_options()->first()?->option;
$givenAnswer = $answers->first()?->question_option_id;
foreach ($questionOptions as $questionOption) {
if ($questionOption->id == $givenAnswer) {
$givenAnswer = $questionOption->option;
break;
}
}
return [$correctAnswer, $givenAnswer];
}As shown in the example your customer method should return an array with two elements the first one being the correct answer and the second element being the user's answer for the question.
And whatever the $data you send to the validate() will be sent to these custom methods so that you can send additional data for rendering the answers.
