我想用PHP學習MongoDB。我可以使用 - > save($ object)成功保存一個新文檔。我的目標是將子文檔添加到具有特定_id的文檔中。PHP/MongoDB - 用_id將文檔添加到文檔
我有一個文件:
"5197f4bef045a1d710000032": {
"_id": {
"$id": "5197f4bef045a1d710000032"
},
"tag": 5487,
"serial": "1z5589ss56",
"type": "Soda Can",
"dept": "NOC",
"location": "Mitchell",
"date": 1368913086,
"moves": null
}
我想插入一個新的文檔到「動作」。
我已經能夠使用$ set一次,但是後續的$ push什麼都不做。
<?php
$m = new Mongo();
$d = $m->selectDB('peeps');
$c = $d->family;
$fields = array('tag' => 5487 , 'serial' => '1z5589ss56', 'type' => 'Soda Can', 'dept' => 'NOC', 'location' => 'Mitchell', 'date' => time());
$can = new Asset($fields);
#$c->save($can);
#Update to insert move
$c->update(array('_id' => new MongoID('5197f0cef045a1d710000032')), array('$push' => array('moves' => $can)));
$cur = $c->find();
$J = json_encode(iterator_to_array($cur));
print($J);
class Asset{
public $tag;
public $serial;
public $type;
public $dept;
public $location;
public $date;
public $moves;
public function __construct($fields){
$this->tag = $fields['tag'];
$this->serial = $fields['serial'];
$this->type = $fields['type'];
$this->dept = $fields['dept'];
$this->location = $fields['location'];
$this->date = $fields['date'];
}
}
基於我已閱讀,這應該創建一個嵌套的文檔中5197f0cef045a1d710000032.moves每次我重新加載頁面的時間。
我不知道我錯過了什麼。
感謝,

謝謝你,我不知道爲什麼我無法在森林中找到樹。 :) – xandout
