Validating multiple files in array
提问by LaserBeak
I need to validate multiple uploaded files, making sure they are of a specific type and under 2048kb. The below doesn't appear to check all files in the array 'files' and just presumes the posted files of invalid mime type as it seems to be checking the array object and not its contents.
我需要验证多个上传的文件，确保它们属于特定类型且小于 2048kb。下面的内容似乎没有检查数组“文件”中的所有文件，只是假设已发布的文件为无效 mime 类型，因为它似乎正在检查数组对象而不是其内容。
public function fileUpload(Request $request)
{
$validator = Validator::make($request->all(), [
'files' => 'required|mimes:jpeg,jpg,png',
]);
if ($validator->fails())
{
return response()->json(array(
'success' => false,
'errors' => $validator->getMessageBag()->toArray()
), 400); }
}

You can validate file array like any input array in Laravel 5.2. This feature is new in Laravel 5.2. You can do like following:
您可以像Laravel 5.2 中的任何输入数组一样验证文件数组。此功能是 Laravel 5.2 中的新功能。您可以执行以下操作：
$input_data = $request->all();
$validator = Validator::make(
$input_data, [
'image_file.*' => 'required|mimes:jpg,jpeg,png,bmp|max:20000'
],[
'image_file.*.required' => 'Please upload an image',
'image_file.*.mimes' => 'Only jpeg,png and bmp images are allowed',
'image_file.*.max' => 'Sorry! Maximum allowed size for an image is 20MB',
]
);
if ($validator->fails()) {
// Validation error..
}

Please try this:
请试试这个：
public function fileUpload(Request $request) {
$rules = [];
$files = count($this->input('files')) - 1;
foreach(range(0, $files) as $index) {
$rules['files.' . $index] = 'required|mimes:png,jpeg,jpg,gif|max:2048';
}
$validator = Validator::make($request->all() , $rules);
if ($validator->fails()) {
return response()->json(array(
'success' => false,
'errors' => $validator->getMessageBag()->toArray()
) , 400);
}
}

Try this way.
试试这个方法。
// getting all of the post data
$files = Input::file('images');
// Making counting of uploaded images
$file_count = count($files);
// start count how many uploaded
$uploadcount = 0;
foreach($files as $file) {
$rules = array('file' => 'required'); //'required|mimes:png,gif,jpeg,txt,pdf,doc'
$validator = Validator::make(array('file'=> $file), $rules);
if($validator->passes()){
$destinationPath = 'uploads';
$filename = $file->getClientOriginalName();
$upload_success = $file->move($destinationPath, $filename);
$uploadcount ++;
}
}
if($uploadcount == $file_count){
//uploaded successfully
}
else {
//error occurred
}

we can also make a request and validate it.
我们也可以提出请求并验证它。
php artisan make:request SaveMultipleImages
here is the code for request
这是请求的代码
namespace App\Http\Requests;
use App\Core\Settings\Settings;
use Illuminate\Foundation\Http\FormRequest;
class SaveMultipleImages extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return ['files.*' => "mimes:jpg,png,jpeg|max:20000"];
}
}
and then in controller
然后在控制器中
public function uploadImage(SaveMultipleImages $request) {
dd($request->all()['files']);
}
