Question

我有以下控制器，我想上传相同的文件并保存在不同的文件夹中，但我的第二个saveAs()无效。

$model->profil_picture_file = UploadedFile::getInstance($model,'profil_picture_file');
$model->profil_picture_file->saveAs('path to first folder'); //it works image saved
$model->profil_picture_file->saveAs('path to second folder'); //doesn't work not saved

让我知道我做错了什么？为什么会出错？

提前致谢。

Answer 1

像这样使用：

$model->profil_picture_file = UploadedFile::getInstance($model,'profil_picture_file');
$model->profil_picture_file->saveAs('path to first folder', false); //set deleteTempFile  param to false
$model->profil_picture_file->saveAs('path to second folder'); //it will work now and delete temp file

saveAs()接受2个参数 - file和deleteTempFile

文档：Yii2 UploadedFile::saveAs()

Answer 2

因为文件saveAs使用移动文件的move_uploaded_file，所以第二个saveAs不起作用，因为文件已经移动了。因此，请使用copy('path to first folder', 'path to second folder')

如何在不同的文件夹中上传相同的文件？
