如何獲得選項？

Question

我正在嘗試做練習。在查看頁面中，每個問題和相應的選項都必須顯示出來。我能夠得到所有問題，但沒有選項。我想我需要通過每個問題ID來顯示相應的選項。但我無法得到。根據問題，有人會幫助您獲得選項。

控制器代碼：

function index() { 


    $data['qn'] = $this->questions_model->questions_list(); 
    foreach($data['qn'] as $row){ 
    $qs_id = $row->qid; 
    $data['qn']['$qs_id']= $this->questions_model->option_list($qs_id); 
    $data['qq_id'] = $data['qn']['$qs_id']; 


    //print_r($data['qq_id']); 
} 

    $this->load->view($this->session->userdata('web_view') . '/header', $data); 
    $this->load->view($this->session->userdata('web_view') . '/questions_list', $data); 
    $this->load->view($this->session->userdata('web_view') . '/footer', $data); 

} 

型號代碼：

function questions_list() { 

$this->db->select('qbank.*,question_category.category_name'); 
    $this->db->from('qbank'); 
$this->db->join('question_category','qbank.cid = question_category.cid'); 
$query = $this->db->get(); 
    if ($query->num_rows() >= 1) { 
     return $query->result(); 
    } else { 
     return false; 
    } 
} 

function option_list($qs_id){ 
$this->db->select('option_value'); 
$this->db->from('q_options'); 
$this->db->where('qid',$qs_id); 

$query = $this->db->get(); 
if ($query->num_rows() >= 1) { 
return $query->result(); 
} else { 
return false; 
} 
} 

視圖代碼：

<form id="profilefrm" class="sky-form" name="profilefrm" method="post"> 
<ol> 
<?php foreach($qn as $row){ ?> 
<li> 
<?php echo $row->question; ?> 
<ol type="A"> 
<?php foreach($qq_id as $rows){ ?> 
<li><?php echo $rows->option_value; ?></li> 
<?php } ?>        
</ol> 
</li> 

<?php } ?> 
</ol> 
</form>

控制器

'foreach($data['qn'] as $row){ 
$qs_id = $row->qid; 
$data['qn']['$qs_id']= $this->questions_model->option_list($qs_id);' 

模型

'function option_list($qs_id){ 
    $this->db->select('option_value'); 
    $this->db->from('q_options'); 
    $this->db->where('q_id','$qs_id'); 
$this->db->limit(4); 
$query = $this->db->get(); 
if ($query->num_rows() >= 1) { 
    return $query->result(); 
} else { 
    return false; 
} '
