Laravel 5.5 - 多张图片上传

Question

我的控制器中有这个功能：

use File;
use Image; //image intervention library
...
public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;

        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '.' . $file->getClientOriginalExtension();
                $path = $folderpath . $filename;
                Image::make($file)->resize(800,400)->save($path);
            endforeach;
        endif;

        return 'success';
    }

如果我上传多张图片，它只会保存最后一张。

我试过了：

public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;

        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '.' . $file->getClientOriginalExtension();
                $path = $folderpath . $filename;
                $file->save($path);
            endforeach;
        endif;

        return ''success;
    }

这给我带来了错误：

方法保存不存在。

我目瞪口呆，似乎我没有用模型实例化它。但是在这种情况下，如果只是直接上传文件，如何用model实例化呢？

在laravel上传多张图片的最佳方式是什么？

更新

阅读@kunal 的回答后，我设法通过为文件名添加唯一编号来解决问题：

public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;
        $count = 0;//<-- add a counter
        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '_' . $count . '.' . $file->getClientOriginalExtension();//<-- add counter to the file name
                $path = $folderpath . $filename;
                Image::make($file)->resize(800,400)->save($path);
                $count ++;//<-- increase the value
            endforeach;
        endif;

        return 'success';
    }

Answer 1

也许你正在寻找这种东西：-

if ($request->hasFile('files')) {
$files = $request->file('files');
foreach($files as $file){
    $extension = $file->getClientOriginalExtension();
    $fileName = str_random(5)."-".date('his')."-".str_random(3).".".$extension;
    $folderpath  = 'images'.'/';
    $file->move($folderpath , $fileName);
}
}
<input type="file" id="gallery" name="files[]" multiple />

Answer 2

我想你可能会错过这部分

<input type="file" id="gallery" name="file[]" />

注意file[]它必须是数组，否则它将是only save the last image if upload multiple image

如果你的 html 部分正确，那么就这样使用，

foreach ($file as $photo) {
    $path = Storage::putFile('foldername', $photo);
}

Answer 3

试试这个代码：

$files= Input::file('image');
$destinationPath= 'images';
$images=array(); 
foreach($files as $file){
    $fullname= $file->getClientOriginalName(); 
    $hashname  = $fullname; 
    $upload_success   =$file->move($destinationPath, $hashname);
    $images[]=$fullname;
    $has= implode(",",$images);
}
$modelname= new Modelname;
$modelname->image_attachment    =  $has;  
$modelname->save();

还有你的html页面：

<input type="file" id="image" name="image[]" />

Answer 4

没那么复杂。 从 larval 5.8 开始，您可以这样做：

collect($request->images)->each(function ($image) {
    return $image->store('images', 'public');
});

将图片放入公共磁盘的images文件夹中。
