【中文标题】使用图像干预的多图像上传。我尝试上传多张图片但无法上传，因为我不知道如何，任何帮助将不胜感激【英文标题】：Multiple Image Uploading using Image Intervention. I tried to upload multiple image but could not as i don't know how, any help would be appreciated 【发布时间】：2021-06-16 01:04:36 【问题描述】：这是我的控制器，谁能告诉我我必须添加更多内容，以便我可以将多个图像添加到我的数据库中 我被指示使用循环，但我不完全知道在哪里使用，所以我添加了我的控制器允许我上传单个图像，但它没有用于上传多个图像。第二个代码是我的刀片文件，表示我创建表单的视图，我的图像的输入类型是“文件”，名称是“文件名”，并且我使用了 Laravel 的图像干预，因此将不胜感激。
public function upload()
$images = ImageModel::all();
return view('uploadimage',compact('images'));
public function uploadImage(Request $req)
$this->validate($req, [
'filename' => 'required',
'filename.*' => 'images|mimes:jpeg,png,jpg,gif,svg|max:2048'
]);
$title = $req->title;
$slug = Str::of($title)->slug('-');
$alttext = $req->alttext;
$originalImage= $req->file('filename');
$thumbnailImage = Image::make($originalImage);
$thumbnailPath = public_path().'/thumbnail/';
$originalPath = public_path().'/images/';
$temp = $originalImage->getClientOriginalName();
$temp_ext = explode(".",$temp);
$ext = end($temp_ext);
$filename = time().".".$ext;
$thumbnailImage->save($originalPath.$filename);
$thumbnailImage->resize(150,150);
$thumbnailImage->save($thumbnailPath.$filename);
$imagemodel= new ImageModel();
$imagemodel->title=$title;
$imagemodel->slug=$slug;
$imagemodel->alttext=$alttext;
$imagemodel->filename=$filename;
if($imagemodel->save())
return redirect()->back()->with('msg','Succesfully Uploaded');
我的blade.php文件也包括在内。

【问题讨论】：
【参考方案1】：这个没有使用jquery ajax
//controller
$files = $request->file('images'); //get all files
$images = [];
foreach($files as $file)
$images[] = [ 'image_name' => $this->storeImage($file,'your_path') ];
/*storeImage function could be in same controller or a separate trait file,
if you want to reuse image upload functionality in other controller(for image upload)*/
public function storeImage($file, $path)
$name = str_replace(" ", "_", $file->getClientOriginalName());
$file->storeAs($path , $name);
return $fileName;
ImageModel::insert($images); //save all record at once
//in html code change this line
<input type="file" multiple class="form-control" name="filename[]" id="imgInp">
