mongoDB에서 배열을 업데이트하려고하는데 코드가 오류없이 실행되고 있지만 문서가 업데이트되지 않습니다. 내가 POST 방식으로 다른 파일에서 'ID'를 촬영하고이 파일에 필요한 문서를 검색 한mongoDB에서 PHP 업데이트 쿼리가 작동하지 않습니다.
<?php
include 'connection.php';
session_start();
$username = $_SESSION ['username'];
$collection = $database->selectCollection ($username);
$books = $collection->find (array (
'_id' => new MongoId ($_POST ['id'])
));
$book = $books->getNext();
$imgid = $book ['imgid'];
$id = $book['_id'];
if (isset ($_POST ['formsubmit'])) {
$gridFS = $database->getGridFS();
// if (isset ($_FILES ['pic']))
// $imgid = $gridFS->storeUpload ('pic', array (
// "username" => $username
//));
$collection->update (array (
"_id" => new mongoId ($id)
), array (
'$set' => array (
'bookname' => $_POST ['bookname'],
'authname' => $_POST ['authname'],
'pubname' => $_POST ['pubname'],
'imgid' => $imgid,
'cost' => $_POST ['cost']
)
));
echo '<h3>File Updated Successfully</h3>';
}
$mongo->close();
?>

여기 내 코드입니다. 그럼 난 업데이트 쿼리를 인용했다. 하지만 작동하지 않습니다
이미지가 양식에서 선택되었는지 어떻게 확인합니까? 새로운 이미지가 업로드되면 기존 이미지를 교체하고 싶습니다. 사전
