如何获取列中的所有行以在codeigniter中插入db

I'm trying to insert all rows which showing view in a table but it insert only one row with value '1' not all rows and not that id's contain in a column:

view:

echo"<table class='table table-hover type-list2'id='traineeList'>
                    <tr class='success'>
                        <th>Trainee ID</th>
                        <th>Trainee Name</th>
                        <th>Present</th>
                    </tr>";
            foreach($list['trainee'] as $row){ 
                echo "
                    <tr><td>".str_pad($row->TraineeID,7,"0", STR_PAD_LEFT)."</td>
                        <td>".$row->Name."</td>
                        <td><input type='checkbox' name='.$row->TraineeID[]' value='".$row->TraineeID."' checked></td>
                    </tr>";
            }
            echo "</table>";

controller:

public function insertAttendance(){
    $data = array('TraineeID'>=$this->input->post('TraineeID'));
    $attnDate=$this->input->post('attnDate');
    $classHour= $this->input->post('classHour');
    foreach ($data as $id){
        $query="INSERT INTO `tbl_attn_temp` (TraineeID, Date, classHour) VALUES ('".$id."','".$attnDate."','".$classHour."')";
        $this->db->query($query);
        redirect('attendance/index/');

    }

see the given link for your question http://codefury.net/2009/12/insert-multiple-rows-into-a-database-with-codeigniter/

Your redirect function should be placed outside of your foreach loop, probably. Looking at your code, your foreach loop will run only once and then redirect you to another page.

Please try with this

    foreach($_POST['TraineeID'] as $key => $id) {

        $attnDate=$_POST['attnDate'][$key];
        $classHour= $_POST['classHour'][$key];

        $query="INSERT INTO `tbl_attn_temp` (TraineeID, Date, classHour) VALUES ('".$id."','".$attnDate."','".$classHour."')";
        $this->db->query($query);
    }
     redirect('attendance/index/');
