我在将我的答案值中的数据从复选框发送到数据库中的选定行时遇到问题

我也在使用分页。

这是我的控制器：

function index() {
        $this->load->library('pagination'); // pagination setting start from here
        $config['base_url'] = site_url('dcm/index');
        $config['per_page'] = 6;
        $config['num_link'] = 5;
        $config['next_link'] = 'Next';
        $config['prev_link'] = 'Prev' ;
        $config['total_rows'] = $this->db->get('soal')->num_rows();

        /* here we are the main problem */
        $data['form_action'] = site_url('dcm/index'); 
        $jawab = $this->input->post('jawab');       //<-- $jawab AS answer, this variable grab answer  
        $id_soal = $this->input->post('id_soal');   //<--  $id_soal AS ID, this variable just for posting ID
        $this->dcm_model->inputJawab(); // <-- for sending data to Model 

        /* pagination */
        $this->pagination->initialize($config);
        $data['query'] = $this->db->get('soal', $config['per_page'], $this->uri->segment(3));
        $data['link'] = $this->pagination->create_links();
        $this->load->view('dcm/soal', $data); }

这是我的模型代码：

function inputJawab(){
    $data   = array();
    if($this->input->post('jawab')){
        $jawab    = $this->input->post('jawab');
        foreach($jawab as $each){
            if(isset($each) && $each != ""){
                $data['jawab'] = "1"; 
                $this->db->where('id_soal', $each)->update('soal', $data); 
            } // 'soal' is my table name
        } // 'id_soal' is my column name AS id
    } // 'jawab' is my column name AS answer
}

这是我的视图代码：

<form action="<?php echo $form_action; ?>" method="post">
<?php echo $link; ?> <!-- <-- for pagination link -->
<!-- HERE WE ARE -->
<?php  foreach($query->result() as $row) { ?>
<span> <?php echo $row->id_soal . '. ' . $row->soal; ?></span>
<input type="checkbox" checked="checked"  value="1<?=$row->id_soal?>" name="jawab[]" />
<input align='center' type='submit' value='SELESAI' />

这是我的数据库架构：

CREATE TABLE `soal` (                                      
      `id_soal` int(10) NOT NULL AUTO_INCREMENT,               
      `id_bagian` int(10) DEFAULT NULL,                        
      `soal` varchar(256) DEFAULT NULL,                        
      `jawab` int(5) DEFAULT NULL,                             
      PRIMARY KEY (`id_soal`)                                  
    ) ENGINE=InnoDB AUTO_INCREMENT=232 DEFAULT CHARSET=latin1
