从数据库中提取时，我在codeigniter中收到错误。
这是我的错误：

$this->session->sess_destroy();
redirect('Welcome', 'refresh');

}
这是我的模特： 的 module.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class User_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
function search($CustomerName,$CustomerID)
{
$this->db->like('CustomerName',$CustomerName);
$this->db->like('CustomerID',$CustomerID);
$query = $this->db->get('gst_customermaster');
return $query->result();
}
}?>

在您的视图中。如果设置了$results数组，则显示表格。因为您正在将不同功能的不同数据发送到同一视图。
喜欢这个..
<?php if(isset($results)){ ?>
<table class='table table-bordered'>
<thead>
<tr>
<th> Customer Name </th>
<th> Customer Id</th>
<th> Customer Code</th>
</tr>
</thead>
<tbody>
<?php foreach($results as $row){ ?>
<tr>
<td><?php echo $row->CustomerName;?></td>
<td><?php echo $row->CustomerID;?></td>
<td><?php echo $row->CustomerCode;?></td>
</tr>
<?php } ?>
</tbody>
</table>
<?php } ?>

获取索引中的所有数据。试试这个：
<强> module.php
class User_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
function search($CustomerName)
{
$this->db->like('CustomerName',$CustomerName);
$query = $this->db->get('gst_customermaster');
return $query->result();
}
function getAll()
{
$query = $this->db->get('gst_customermaster');
return $query->result();
}
}?>`enter code here`
控制器文件：
