我想保存所有我選擇的複選框值

Question

我嘗試存儲複選框的值subject_id，但是當我將此值存儲到數據庫時，它只是將最後選定的複選框存儲在數據庫中...請幫助我整理代碼所以我可以得到所有選定的值。

我想保存所選擇的所有複選框值，但如果我選中多個複選框，它總是保存最後一個複選框。

function get_class_section($day='',$section='',$class='') 
{ 

    print_r($section); 
    $sections = $this->db->get_where('class_routine' , array(
     'day' => $day,'section_id'=>$section,'class_id'=>$class 
    ))->result_array(); 


    foreach ($sections as $row) { 


    echo "<table class=\"table table-bordered datatable\" id=\"table_export\" >"; 

    echo "<thead>"; 
    echo "<th>Subject</th><th colspan=\"2\">status</th>"; 
    echo "</thead>"; 

    echo "<tbody>"; 
    echo "<tr>"; 

    echo "<td>". $this->crud_model->get_subject_name_by_id($row['subject_id'],"<input type=\"text\" name=\"subject_id\" value=\"subject_id\" >"); 
    echo "<input type=\"checkbox\" name=\"types[]\" value=\"".$row['subject_id']."\" set_checkbox('types[]', 'subject_id')>"; 

     echo "</td>"; 

    echo "<td>present&nbsp;&nbsp;<input type=\"checkbox\" value=\"1\" ></td>" 
     . "<td>Absent&nbsp;&nbsp;<input type=\"checkbox\" name=\"types[]\" value=\"0\"></td>"; 



    echo "</tr>"; 
    echo "</tbody>"; 

    echo "</table>"; 




    } 

} 

如何保存的一切，我選擇

Answer 1

你需要foreach循環到獲取所有選中的複選框

試試這個：

if(isset($_REQUEST['types']) && $_REQUEST['types']!=array()) 
{ 
    foreach ($_REQUEST['types'] as $key => $value) { 

    // in $value,you will get checkbox value 

    } 
} 

Answer 2

您應該使用隱藏的元素爲所有複選框

嘗試的複選框這個

. "<td>Absent&nbsp;&nbsp;<input type=\"checkbox\" name=\"types[]\" value=\"0\"></td> 
<input type=\"hidden\" name=\"types[]\" value=\"0\"> ";
