Laravel 5动态地将图像移动到另一个文件夹

I have a fileupload module in my app. I can upload files in img/upload/{container_id}/file_name_here.

The {container_id} will depend on what folder the user will use.

The problem I encountered is when they try to edit a record to another folder. The file that they uploaded remains in the old folder.

I want to move the file also to the new folder the user defines.

I have here my code, I'm stuck in moving the file.

$attachments = Attachment::where('document_id',$id)->select('filename')->get();
        $document = Document::findOrFail($id);

        foreach($attachments as $attachment)
        {
            $attachment->filename = base_path().'/public/img/upload/'.$document->container_id."/".$attachment->filename;
        }

        Document::findOrFail($id)->update($request->all());

        $document = Document::findOrFail($id);

        $x = Attachment::where('document_id','=',$id)->count();

        foreach($attachments as $file)
        {

            HOW_DO_I_MOVE_THE_FILE????
            $x++;
        }

        return redirect('documents');

Update:

In your case, you should use rename():

rename ('current/path/to/foo', 'new/path/to/foo');

With rename() you can not only rename, but also move! Simply, if the path of the second param differs. So you can use in your loop the attachment path as first param, and a destination path as second.

Documentation: http://php.net/rename

Below the Laravel approach for moving after upload.

From the documentation:

$request->file('photo')->move($destinationPath);

$request->file('photo')->move($destinationPath, $fileName);

photo is the name of your file upload input element.

Note, you can use the array notation, if you've multi upload, such as:

foreach ($request->file('photo') as $photo)
{
    $photo->move($destinationPath, $chooseYourFileName);
}
