<body> 
<form method="post" action="http://localhost/cinema/Movies/select_combo" name="selectshow" accept-charset="utf-8" class="username"> 
<?php 

$prevRowId = null; 
$seatColor = null; 
$tableRow = false; 
//echo $result; 
echo "<table width='100%' border='0' cellpadding='0' cellspacing='2'>"; 
foreach($query as $key=>$result) 
{ 
    $rowId = $result['rowId']; 
    $status = $result['status']; 
    $columnId = $result['columnId']; 
    $typeID=$result['seat_type_id']; 
if ($prevRowId != $rowId) { 
if ($rowId != 'A') { 
    echo "</tr></table></td>"; 
    echo "\n</tr>"; 
} 
$prevRowId = $rowId; 
echo "\n<tr><td align='center'><table border='0' cellpadding='5' cellspacing='2'>  <tr>"; 
} else { 
$tableRow = false; 
} 
if ($status == 0) { 
if($typeID==1) 
    $seatColor = "grey"; 
else if($typeID==2) 
    $seatColor="yellow"; 
else 
    $seatColor="white"; 
} 
else { 
$seatColor = "red"; 
} 

echo "\n<td bgcolor='$seatColor' align='center'>"; 
echo "$rowId$columnId"; 
if ($status == 0) 
{ 
echo "<input type='checkbox' name='seats[]' value='$rowId$columnId'></checkbox>"; 
} 
echo "</td>"; 
if (($rowId == 'A' && $columnId == 6) 
    || ($rowId == 'B' && $columnId == 7) 
    || ($rowId == 'C' && $columnId == 7) 
    || ($rowId == 'D' && $columnId == 7) 
) { 
// This fragment is for adding a blank cell which represent the "center aisle" 
echo "<td> </td>"; 
} 
} 
echo "</tr></table></td>"; 
echo "</tr>"; 
echo "</table>"; 

mysql_close(); 
?> 
<input type="submit" class="button-link" style="float:right; margin-top: 20px; margin-right:0px; margin-bottom: 10px;" value="Submit" /> 
    </form> 
</body> 
</html>

型號

<?php 
class Selectseat extends CI_Model { 
    public function __construct() 
    { 
     $this->load->database(); 
    } 

    function get() { 
     return $this->db->query("SELECT * from seats order by rowId, columnId asc") 
      ->result_array(); 
    } 
} 
?>

控制器

function select_combo(){ 
     foreach($this->input->post('seats[]') as $seat) 
      $data['seats']=$seat; 
    $this->session->set_userdata($data); 

     $this->load->model('combo_model'); 
    $data['combos'] = $this->combo_model->get_combo(); 
    $this->load->view('header'); 
     $this->load->view('select_combo',$data); 


    }

快速的發現：

具有值數組

$this->input->post('seats[]')

相反

$seats = $this->input->post('seats');

現在的席位不能使用。

您可以更改如下代碼：

function select_combo(){ 
    $data['seats']=$this->input->post("seats"); 
    $this->session->set_userdata($data); 

    $this->load->model('combo_model'); 
    $data['combos'] = $this->combo_model->get_combo(); 
    $this->load->view('header'); 
    $this->load->view('select_combo',$data); 


    }

肯定。可能。檢查你的html。 '也''怪。有沒有這樣的標籤？ –

非常感謝您的快速回復！它的作品完美.. – user3142334

可以請你告訴我如何使用此會話數組存儲在數據庫中的一列。 – user3142334
