How can I get insert id of bulk flush in symfony2

本文关键字：刷新插入 id 获取 symfony2 | 更新日期: 2023-09-27

如何从大容量插入数据中获取所有插入ID？我的代码如下：

 foreach ($urls as $url) {
        $subDocument = new SubDocument();
        $subDocument->setUrl($url);
        $subDocument->setParentDocument($parentDocument);
        $dm->persist($subDocument);
    }
    $dm->flush();
    $dm->clear();

现在，我如何才能获得这些记录的插入ID？

您可以在$dm->flush();之后访问Subdocument的ID，因此您必须保留Subdocument的实例以在刷新后检索其ID。

 $subDocuments = array(); // init array
 foreach ($urls as $url) {
    $subDocument = new SubDocument();
    $subDocument->setUrl($url);
    $subDocument->setParentDocument($parentDocument);
    $subDocuments[] = $subDocument; //added to array
    $dm->persist($subDocument);
}
$dm->flush();
//now you can access IDs iterating $subDocuments like:
foreach($subDocuments as $subDocument) {
    echo $subDocument->getId();
}
