cakephp - 在更新时不要更改空字段

Question

我使用cakephp 2.5.4并且想要在数据库中更新记录时，空字段，不要更改

这是我的更新功能

...
   if ($this->User->save($this->request->data)) {
       return $this->User->id;
   }
...

Answer 1

在保存数据之前，请从阵列中删除空值。

foreach ($this->request->data as $key => $value) {
    if (empty($value))
        unset($this->request->data[$key]);
}

if ($this->User->save($this->request->data)) {
   return $this->User->id;
}

Answer 2

添加条件 -

$conditions = array(
               'conditions' => array('my_field IS NOT NULL')
              );

$this->User->updateAll($this->request->data, $conditions);

并且您不需要$this->User->getLastInsertId();，您将通过$this->User->id;
