Question

我需要为列生成唯一值。我想增加表中最后插入的值。

我试过这个，但无济于事

if($this->request->is('post')){
    $code = $this->Department->find('first', array(
        'fields' => 'Department.code',
        'order'  => 'Department.code DESC'
    ));
    $code += 1;
    $this->data['Department']['code'] = $code;
    if($this->Department->save($this->request->data)){
        $this->Session->setFlash('New department added.');
        $this->redirect(array('action' => 'add'));
    }
}

谢谢！

Answer 1

您正在保存 $ this-＆gt; request-＆gt; data ，但您将数据存入 $ this-＆gt;数据。

试试这个：

if($this->request->is('post')){
    $code = $this->Department->find('first', array('fields' => 'Department.code','order' => 'Department.code DESC'));
    $code += 1;
    $this->request->data['Department']['code'] = $code;
    if($this->Department->save($this->request->data)){
        $this->Session->setFlash('New department added.');
        $this->redirect(array('action' => 'add'));
    }
}

Answer 2

$ id = $ this-＆gt; User-＆gt; getLastInsertId（）;

通过此函数，您将获得最后一个插入的id，现在递增其值并在您想要使用的位置使用它或者将该id添加到数据库中并将其保存在数据库中
