在Cakephp 3上只更新一个字段

Question

在我的应用程序的某些部分,我需要更新is_active一些table有很多字段的字段.仅更新此字段并避免所有其他字段的验证和要求的最佳方法是什么？

Answer 1

如果您只想更新特定行,请使用:

 $users= TableRegistry::get('Users');
 $user = $users->get($id); // Return article with id = $id (primary_key of row which need to get updated)
 $user->is_active = true;
 // $user->email= abc@gmail.com; // other fields if necessary
 if($users->save($user)){
   // saved
 } else {
   // something went wrong
 }

请参见此处(更新CakePHP3中的数据).

Answer 2

这将有效:

$users = TableRegistry::get('Users');
$query = $users->query();
$query->update()
    ->set(['is_active' => true])
    ->where(['id' => $id])
    ->execute();
