如何在Laravel 5.3 中上传多个文件。
如果我尝试使用 1 张图片，它可以工作，但不会上传多张图片。
这是我的代码：
if($request->hasFile('attachment')) {
foreach($request->allFiles('attachments') as $file) {
$file->store('users/' . $user->id . '/messages');
}
}
【问题讨论】：
public function MultiImage(Request $request)
{
$postimage=new Photo;
if($request->hasfile("file")){
foreach($request->file("file") as $img) {
$filename = $img->getClientOriginalName();
Image::make($img)->resize(200, 200)->save('banner/uploads/photo/'.$filename);
$uploadPath = 'banner/uploads/photo/'.$filename;
$data[]=$filename;
}
$postimage->code = time();
$postimage->name = $filename;
$postimage->private_state = $request->input('private_state');
$postimage->description = $request->input('description');
$postimage->titre = $request->input('titre');
$postimage->mute = $request->input('mute');
$postimage->user_id = $request->input('user_id');
$postimage->save();
}
return redirect()->route('timeline-photos');
}

这是在 laravel 中上传多个文件的控制器：
public function fileUpload(Request $request)
{
if ($request->hasfile('filenames')) {
foreach ($request->file('filenames') as $file) {
$name = $file->getClientOriginalName();
$file->move(public_path() . '/mytestfile/', $name);
$data[] = $name;
}
return back()->with('Success!','Data Added!');
}
}
资源中的这个视图文件：
<html lang="en">
<head>
<title>Multiple Image Upload</title>
<script src="jquery/1.9.1/jquery.js"></script>
<link rel="stylesheet" href="3.3.6/css/bootstrap.min.css">

<body>
<div class="container lst">

<script type="text/javascript">

$(".btn-success").click(function(){
var lsthmtl = $(".clone").html();
$(".increment").after(lsthmtl);
});
$("body").on("click",".btn-danger",function(){$(this).parents(".hdtuto control-group lst").remove();
});
});
</script>

这是我的刀片的样子：
<div class="form-group row">
<label for="gallery-image" class="col-sm-3 text-left control-label col-form-label">Photo</label>
<div class="col-md-9">
{{-- <input type="file" name="images[]" multiple> --}}
<input type="file" class="form-control form-control-file"
id="gallery-image" value="{{ old('gallery-image') }}" required name="gallery-image[]" multiple/>
<span class="below-image-upload-msg">Advised image dimensions: 1920 x 450 pixels. File size should be less than 2Mb per image.</span>
</div>
@error('image')
<span class="invalid-feedback" role="alert">
<strong>{{ $message }}</strong>
</span>
@enderror
</div>
这就是控制器中的 store 函数的样子：
public function store(Request $request){
$validation = Validator::make($request->all(), array(
'gallery-id' => 'required|integer|min:0',
'gallery-image' => 'required|image|nullable|mimes:jpeg,png,jpg,gif|max:2048',
));
$fileNameToStore="no-image.jpg";
if(request('gallery-image'))
{
$iCount=0;
foreach($request->file('gallery-image') as $thisImage){
$fileNameWithExtension = $thisImage->getClientOriginalName();
$memberName = Auth::user()->MemberProfile->member_tourist_office_name;
$extension=$thisImage->getClientOriginalExtension();
$fileNameToStore = $fileName.'_'.time().$iCount.'.'.$extension;
$path= $thisImage->storeAs('public/images/members/gallery-images',$fileNameToStore);
$isEnabled = "0";
$galleryImage = new GalleryImage();
$galleryImage->gallery_id = request('gallery-id');
$galleryImage->gallery_image_caption = " ";
$galleryImage->gallery_image = $fileNameToStore;
$galleryImage->isEnabled = $isEnabled;
$galleryImage->save();
$iCount++;
}
return redirect('/galleryimage/create')->with('success', 'Image(s) successfully added to gallery!');
}
}
【讨论】：
用这个更简单的方法解决了这个问题。只要确保您的输入文件类型是这样的<input type="file" name="images[]" multiple>
$i = 0;
foreach($request->file('images') as $file){
$photo = new Photo;
// name it differently by time and count
$imageName = time() . $i . '.' . $file->getClientOriginalExtension();
// move the file to desired folder
$file->move('folderName/', $imageName);
// assign the location of folder to the model
$photo->image = 'folderName/' . $imageName;
$photo->status = 1;
$photo->save();
$i++;
}

Controller.Php / Laravel 5.7.28
$files = $request->file('product_image_id');
if($request->hasFile('product_image_id')){
foreach ($files as $file) {
$name = time(). $file->getClientOriginalName();
$file->move('images',$name);
$productImage = ProductImage::create(['image'=>$name]);
$input ['product_image_id'] = $productImage->id;
}
}
【讨论】：
试试这样的：
public function multiple_upload() {
// 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 ++;
}
}
}
【讨论】：
如果你还想继续使用刀片，你可以使用这个：
{{ Form::open(array('url' => 'upload', 'files'=>true)); }}
{{ Form::file('gallery[]', array('multiple'=>true,'accept'=>'image/*')); }}
{{ Form::submit(); }}
{{ Form::close(); }}
在你的控制器中：
files = $request->file('gallery');
if($request->hasFile('gallery'))
{
foreach ($files as $file) {
// $file->store('users/' . $this->user->id . '/messages');
//dump($file);
}
}
【讨论】：
它现在是这样工作的：
$files = $request->file('attachment');
if($request->hasFile('attachment'))
{
foreach ($files as $file) {
$file->store('users/' . $this->user->id . '/messages');
}
}
我必须在name 属性的值之后附加[]，所以：
<input type="file" name="attachment[]" multiple>
【讨论】：
attachment[] 未显示在您的代码中？你的意思是应该这样吗？
