Laravel5文件上传默认只能上传一张图片，但是有的时候我们需要一次性上传多图就不行了，我在网上看了很多关于laravel5图片上传的文章，很多都只是介绍laravel5单图上传,多图片上传介绍少之有少，今天分享一篇关于laravrl5多图上传文章，代码逻辑设计可能不完美，但功能实现了。希望对大家有所帮助！
前端代码：
注意：<input type="file" class="default" name="img[]" />
<!------bootstrap-fileupload.min.js 图片上插件-------><link href="{{url(‘Admin/css/bootstrap-fileupload.min.css‘)}}" rel="stylesheet"><script src="{{url(‘Admin/js/bootstrap-fileupload.min.js‘)}}"></script><!------上传正面图片 start-------><div class="form-group last"><label class="control-label col-md-2">选择图片 <i style="color: red;">*</i></label><div class="col-md-9"><div class="fileupload fileupload-new" data-provides="fileupload"> ???<div class="fileupload-new thumbnail" style="width: 210px; height: 150px;"><img src="{{url(‘Admin/images/23.jpg‘)}}" ?/> ???</div> ???<div class="fileupload-preview fileupload-exists thumbnail" style="max-width: 200px; max-height: 150px; line-height: 20px;"></div> ???<div> ??????<span class="btn btn-default btn-file"> ??????<span class="fileupload-new"><i class="fa fa-paper-clip"></i> 上传图片</span> ??????<span class="fileupload-exists"><i class="fa fa-undo"></i> Change</span> ??????<input type="file" class="default" name="img[]" /> ??<!--<input type="hidden" class="default" name="old-img" value="{$data.img}" />--> ??????</span> <a href="#" class="btn btn-danger fileupload-exists" data-dismiss="fileupload"><i class="fa fa-trash"></i> 删除</a> ???</div></div></div></div><!------上传正面图片 end-------><!------上传背面图片 start-----><div class="form-group last"><label class="control-label col-md-2">选择图片 <i style="color: red;">*</i></label><div class="col-md-9"><div class="fileupload fileupload-new" data-provides="fileupload"> ???<div class="fileupload-new thumbnail" style="width: 210px; height: 150px;"><img src="{{url(‘Admin/images/23.jpg‘)}}" ?/> ???</div> ???<div class="fileupload-preview fileupload-exists thumbnail" style="max-width: 200px; max-height: 150px; line-height: 20px;"></div> ???<div> ??????<span class="btn btn-default btn-file"> ??????<span class="fileupload-new"><i class="fa fa-paper-clip"></i> 上传图片</span> ??????<span class="fileupload-exists"><i class="fa fa-undo"></i> Change</span> ??????<input type="file" class="default" name="img[]" /> ??<!--<input type="hidden" class="default" name="old-img" value="{$data.img}" />--> ??????</span> <a href="#" class="btn btn-danger fileupload-exists" data-dismiss="fileupload"><i class="fa fa-trash"></i> 删除</a> ???</div></div></div></div><!------上传背面图片 end------->
Laravel5单图上传：
public function upload(Request $request){//判断请求中是否包含name=img的上传文件if (!$request->hasFile(‘img‘)) { ???exit("请选择上传图片， <a href=‘‘>返回上一页！</a>");}// 判断图片上传中是否出错$file = $request->file(‘img‘);if (!$file->isValid()) { ???exit("上传图片出错，请重试，<a href=‘‘>返回上一页！</a>");} //$img_path = $file -> getRealPath(); // 获取临时图片绝对路径 $entension = $file -> getClientOriginalExtension(); // ?上传文件后缀 $filename = date(‘YmdHis‘).mt_rand(100,999).‘.‘.$entension; ?// 重命名图片 $date = date(‘Y-m-d‘); $path = $file->move(public_path().‘/uploads/‘.$date.‘/‘,$filename); ?// 重命名保存 $img_path = ‘uploads/‘.$date.‘/‘.$filename; return $img_path;}Laravel5多图上传：
其实多图片上传就是多了一个foreach循环
public function upload(Request $request){$file = $request->file(‘img‘);$filePath =[]; ?// 定义空数组用来存放图片路径foreach ($file as $key => $value) { ?// 判断图片上传中是否出错 ??if (!$value->isValid()) { ?????exit("上传图片出错，请重试！"); ??} ???if(!empty($value)){//此处防止没有多文件上传的情况 ???$allowed_extensions = ["png", "jpg", "gif"]; ???if ($value->getClientOriginalExtension() && !in_array($value->getClientOriginalExtension(), $allowed_extensions)) { ???????exit(‘您只能上传PNG、JPG或GIF格式的图片！‘); ???} ???$destinationPath = ‘/uploads/‘.date(‘Y-m-d‘); // public文件夹下面uploads/xxxx-xx-xx 建文件夹 ???$extension = $value->getClientOriginalExtension(); ??// 上传文件后缀 ???$fileName = date(‘YmdHis‘).mt_rand(100,999).‘.‘.$extension; // 重命名 ????$value->move(public_path().$destinationPath, $fileName); // 保存图片 ???$filePath[] = $destinationPath.‘/‘.$fileName; ????}}// 返回上传图片路径，用于保存到数据库中return $filePath;}Laravel5多图上传和Laravel5单图上传的功能实现
