Question

基本上我正在实施MCQ问题。一切都很简单。单一表格，包含所有问题（从数据库中提取）和选项。

我被困在需要检查用户选择的答案是否正确的地方。

有一个单独的数据库，其中包含与所有问题相对应的正确选项喜欢

array(q_1 => 3,
      q_2 => 2,
      q_3 => 4,
      ); //just an example

代码：

这是一次失败的尝试

public function checkAnswers($submition){
    //compare array with db right answers
        $correct = array();
    foreach ($submition as $attempt){
            $x = 0;
            if ($attempt == $this->_db->get('answers', array('q_id','=','1')){
                $correct[$x] = "yes";
            }

    }
    return $correct;
    //$this->displayFinalScore()
}

这就是我收到提交的方式

$score->checkAnswers(array(
                    'question1'     => Input::get('question1'),
                    'question2'     => Input::get('question2'),
                    'question3'     => Input::get('question3'),
                    'question4'     => Input::get('question4'),
                    'question5'     => Input::get('question5'),
                    'time'          => 300,
                )));

请在投票之前告诉我是否需要更多代码来帮助我。感谢。

感谢您对安德鲁的帮助，但我采取了不同的方法并弄明白了。这是答案：

    public function checkAnswers($submition){
    //compare array with db right answers
    $answers = $this->getAnswerKey();
    //$answer->q_id == question id & $asnwer->option_id == correct answer
    //submittion for each question in loop is $submition[$question->q_id]
    foreach ($answers as $answer) {

        if($submition[$answer->q_id] == $answer->option_id){
            $this->score = $this->score + 4;
        }
    }
    $this->createEntry($this->score, $submition['user_id']);

}

希望这会帮助有需要的人！
