问题描述
这一定很简单，但我似乎无法弄清楚...假设我有一个集合 users，这是集合中的第一项:
This has to be easy, but i can't seem to figure it out... Let say i had a collection users and this is the first item in the collection:
{
"_id" : ObjectId("4d8653c027d02a6437bc89ca"),
"name" : "Oscar Godson",
"email" : "oscargodson@xxx.com",
"password" : "xxxxxx",
"tasks" : [
{
"task" : "pick up stuff",
"comment" : "the one stuff over there"
},
{
"task" : "do more stuff",
"comment" : "lots and lots of stuff"
}
] }
然后我将如何使用 MongoDB 的 PHP 驱动程序将另一个任务"添加到集合中此项的任务"数组中
How with the PHP driver for MongoDB would I then go and add another "task" to the "tasks" array in this item in a collection
推荐答案
使用Mongo的$push操作:
Use Mongo's $push operation:
$new_task = array(
"task" => "do even more stuff",
"comment" => "this is the new task added"
);
$collection->update(
array("_id" => ObjectId("4d8653c027d02a6437bc89ca")),
array('$push' => array("tasks" => $new_task))
);
