使用一个更新查询设置多个字段 [英] Set multiple fields with one update query

问题描述

以下代码应该可以工作.我本可以错过一些东西，但是现在我将其作为2条单独的更新语句，并决定在这里询问为什么此行不起作用.

The following code should work. I could have missed something, but right now I have it as 2 separate update statements and have decided to ask here why this line isn't working.

$this->db->settings->update(array('_id' => $mongoID),
  array(
    '$set' => array('about' => $about),
    '$set' => array('avatar' => $avatar)
  )
);

阅读指南时我是否错过了某些东西?还是只能使用单独的更新语句?

Did I miss something when reading guides or is it only possible to do with separate update statements?

推荐答案

MongoCollection::update 是更新操作的选项数组.

The third argument to MongoCollection::update is an array of options for the update operation.

$this->db->settings->update(
    array('_id' => $mongoID),
    array('$set' => array('about' => $about, 'avatar' => $avatar))
);
