Upsert-PHP Mongodb-无法插入新记录

我正在运行以下代码.如果记录已经存在,则将其替换为$updated_fields_array中的新字段.但是,如果记录不存在,我将不知道如何添加具有新字段($new_fields_array)的新记录.我应该使用哪个操作符？有人可以帮我吗？

    $current_time = time();
    $current_mongo_date = new MongoDate($current_time);

    $collection = $this->mongo->selectCollection(MONGO_NOTIFY_DB, 'AccountSettings');

    $criteria_array=array("email" => $email, "name" => $name);

    $updated_fields_array = array (
        'last_sent' => $current_time,
        'updated' => $current_mongo_date
    );

    $new_fields_array = array (
        'created' => $current_mongo_date,
        'updated' => $current_mongo_date,
        'email' => $email,
        'name' => $name,
        'last_sent' => $current_time,
        'deleted' => FALSE
    );

    try {

        $collection->update(
            $criteria_array,
            array('$set' => $updated_fields_array),
            array("upsert" => true)
        );

    } catch (MongoCursorException $mce) {
        log_message('error', 'QUERY UPDATE FAILED :: AccountSettings :: ' . print_r($updated_fields_array, true) . ' :: ' . $mce->getMessage());
    }
    return;

解决方法:

叶夫根尼的答案还可以,但您缺少一个问题

您在update_fields_array和new_fields_array中有重复的键,这会引发MongoDB WriteException,因为Mongo首先会创建新对象,然后才对其进行更新.

所以改变

$updated_fields_array = array (
    'last_sent' => $current_time,
    'updated' => $current_mongo_date
);

$new_fields_array = array (
    'created' => $current_mongo_date,
    'updated' => $current_mongo_date,
    'email' => $email,
    'name' => $name,
    'last_sent' => $current_time,
    'deleted' => FALSE
);

至

$updated_fields_array = array (
    'last_sent' => $current_time,
    'updated' => $current_mongo_date
);

$new_fields_array = array (
    'created' => $current_mongo_date,
    'email' => $email,
    'name' => $name,
    'deleted' => FALSE
);

并更改查询(如Evgeny所写或Documentation)

$collection->update(
        $criteria_array,
        array('$set' => $updated_fields_array, '$setOnInsert'=> $new_fields_array),
        array("upsert" => true)
);
