[英]PHP MongoDB update doesn't work
{
"__v" : 2,
"_id" : ObjectId("54dc4fd10ac1f6a066a0646c"),
"desc" : "test1",
"lists" : [
{
"index" : 1,
"text" : "__point",
"_id" : ObjectId("54dc4fda0ac1f6a066a0646d"),
"createdAt" : ISODate("2015-02-12T07:01:46.390Z")
},
{
"index" : 2,
"text" : "__point",
"_id" : ObjectId("54dc4fdd0ac1f6a066a0646e"),
"createdAt" : ISODate("2015-02-12T07:01:49.668Z")
}
],
"name" : "test" }
The test array looks like this. 测试数组如下所示。 i want to add 'category' field and add value '0' in lists checking _id. 我想添加“类别”字段并在检查_id的列表中添加值“ 0”。
i tried 我试过了
$collection->update(array('_id' => new MongoId("54dc4fd10ac1f6a066a0646c")),array('$set' => array(new MongoId("54dc4fda0ac1f6a066a0646d").".lists.category" => '0')));
like this but it doesn't work. 这样,但不起作用。
Hi I don't know more about PHP but you can do this from following script 嗨,我对PHP不太了解,但是您可以通过以下脚本进行操作
db.collectionName.find({
"lists": {
"$exists": true
}
}).forEach(function(data){
for(vari=0;i<data.lists.length;i++){
db.collectionName.update({
"_id": data._id,
"lists.index": data.lists[
i
].index
},
{
"$set": {
"lists.$.category": 0
}
},
true,
true);
}
})
set third parameter of update to true.
i think there is some problem in finding which embedded document for updated.
try this one might be work.
$collection->update(array('_id' => new MongoId("54dc4fd10ac1f6a066a0646c"), 'lists._id' => "54dc4fda0ac1f6a066a0646d"), array('$set' => array("lists.$.category" => '0')), true);
