Question

您好我在laravel项目中使用滑行（http://glide.thephpleague.com/）进行图像处理。我在存储图像时遇到问题。 “调用未定义的函数Intervention\Image\Gd\imagecreatefrompng()”

奇怪的是我可以在我的Mac上用“预览”打开图像。但不是在浏览器中。 Photoshop也告诉我这个文件有问题，它已经损坏了。

这是我将图像保存在私人文件夹中的方式：

public function update(Request $request, $id)
{

  //Show the image
  echo '<img src="'.$_POST['img_val'].'" />';

  //Get the base-64 string from data
  $filteredData=substr($_POST['img_val'], strpos($_POST['img_val'], ",")+1);

  //Decode the string
  $unencodedData=base64_decode($filteredData);

  //Save the image
  $storagepath = storage_path('app/images/users/' . Auth::user()->id);
  $imgoutput = File::put($storagepath.'/flyer.jpg', $unencodedData);

  return view('backend.flyers.index')->withImgoutput($imgoutput);
                                     //->withStoragepath($storagepath);

}

似乎File :: put（XXX。 jpg ） JPG 会导致问题。我该如何解决这个问题？

这是因为缺少<link href="http://code.ionicframework.com/1.3.1/css/ionic.min.css" rel="stylesheet"/> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/ngDraggable/0.1.10/ngDraggable.js"></script> <div ng-app="MyApp" ng-controller="MyCtrl" class="body"> Categorize the animals based on their reproductive system <div class="row"> <div class="col"> <div class="list-of-drag-item" ng-drop="true" ng-drop-success="onDropComplete0($data,$event)"> <div ng-click="clickMe()" ng-repeat="obj in droppedObjects0" ng-drag="true" ng-drag-data="obj" ng-drag-success="onDragSuccess0($data,$event)" ng-center-anchor="{{centerAnchor}}"> {{obj.name}} </div> </div> </div> </div> <div class="row" style="text-align: center;"> <div class="col div-left"> <span class="title">Animals that give birth <div ng-drop="true" ng-drop-success="onDropComplete1($data,$event)"> <div ng-repeat="obj in droppedObjects1" ng-drag="true" ng-drag-data="obj" ng-drag-success="onDragSuccess1($data,$event)" ng-center-anchor="{{centerAnchor}}"> {{obj.name}} </div> </div> </div> <div class="col div-right"> <span class="title">Animals that Laying Eggs</span> <div ng-drop="true" ng-drop-success="onDropComplete2($data,$event)"> <div ng-repeat="obj in droppedObjects2" ng-drag="true" ng-drag-data="obj" ng-drag-success="onDragSuccess2($data,$event)" ng-center-anchor="{{centerAnchor}}"> {{obj.name}} </div> </div> </div> </div> </div>。试试这个：

您必须启用库GD2。

找到（适当的）GD Library文件

找到行：php.ini并删除前面的分号。

该行应如下所示：

;extension=php_gd2.dll

然后重启apache，你应该好好去。
