我正在尝试更新一个表格,其中输入了行的ID并通过下拉列表选择了标题,但我有两个问题。 首先我不知道如何将数据传递给模型,第二个问题实际上是使用活动记录更新表。
控制器类
class Update extends CI_Controller {
public function __construct()
{
parent::__construct();
//$this->load->model('addmodel');
//$this->load->helper('form');
}
public function index()
{
$this->load->view('updview');
}
public function updtitle()
{
$data = array(
'id' => $this->input->post('id'),
'title' => $this->input->post('title') );
//$data1['data'] = $data;
$data1['data'] = $this->updmodel->upddata($data);
$this->load->view('updview', $data1);
}
}
?>
模型类
class Updmodel extends CI_Model {
// model constructor function
function __construct() {
parent::__construct(); // call parent constructor
$this->load->database();
}
public function upddata($data) {
$this->db->where('emp_no', $data['id']);
$this->db->update('title', $data['title']);
return;
}
}
?>
视图
<form action="http://localhost/ecwm604/index.php/update/updtitle" method="POST">
employee id:
<input type=text name="id"><br />
change title to:
<select name="title">
<option value="Assistant Engineer">Assistant Engineer</option>
<option value="Engineer">Engineer</option>
<option value="Senior Engineer">Senior Engineer</option>
<option value="Senior Staff">Senior Staff</option>
<option value="Staff">Staff</option>
</select><br />
<input type="submit" value="submit"/>
<br />
<?php
print_r($data);
//echo $data['title'];
?>
</body>
</html>

public function updtitle()
{
$data = array(
'table_name' => 'your_table_name_to_update', // pass the real table name
'id' => $this->input->post('id'),
'title' => $this->input->post('title')
);
$this->load->model('Updmodel'); // load the model first
if($this->Updmodel->upddata($data)) // call the method from the model
{
// update successful
}
else
{
// update not successful
}
}
public function upddata($data) {
extract($data);
$this->db->where('emp_no', $id);
$this->db->update($table_name, array('title' => $title));
return true;
}
活动记录查询类似于
"update $table_name set title='$title' where emp_no=$id"

在your_controller中写下这个......
public function update_title()
{
$data = array
(
'table_id' => $this->input->post('table_id'),
'table_title' => $this->input->post('table_title')
);
$this->load->model('your_model'); // First load the model
if($this->your_model->update_title($data)) // call the method from the controller
{
// update successful...
}
else
{
// update not successful...
}
}
在your_model中......
public function update_title($data)
{
$this->db->set('table_title',$data['title'])
->where('table_id',$data['table_id'])
->update('your_table');
}
这样可行......

如何在Codeignitor中更新?
无论何时要用多行更新相同状态,都可以在where中使用where_in,或者如果只想更改一条记录,则可以在where中使用。
下面是我的代码
$conditionArray = array(1, 3, 4, 6);
$this->db->where_in("ip_id", $conditionArray);
$this->db->update($this->table, array("status" => 'active'));
它的工作完美。

在codeigniter doc中,如果您更新特定字段,请执行此操作
$data = array(
'yourfieldname' => value,
'name' => $name,
'date' => $date
);
$this->db->where('yourfieldname', yourfieldvalue);
$this->db->update('yourtablename', $data);
