我安装了补丁“干预/图像”,“必须掌握”,以使我的图像将其大小减少到300乘以300.
我做了一些表格,在我看来总是犯同样的错误.

得到错误？
调节器
public function updateProfile() {
$file = Input::file('imagem');
$profileData = Input::except('_token');
$validation = Validator::make($profileData,User::$profileData);
if ($validation->passes()) {
if ($file == null) {
User::where('id',Input::get('id'))->update($profileData);
Session::flash('message','Perfil editado com sucesso');
return view('backend/perfil.index');
}
$file = array_get($profileData,'imagem');
$destinationPath = 'imagens/perfil';
$extension = $file->getClientOriginalExtension();
$filename = rand(11111,99999) . '.' . $extension;
$reduzir = $filename -> resize (300,300);
$profileData['imagem'] = $filename;
$upload_success = $file->move($destinationPath,$filename);
User::where('id',Input::get('id'))->update($profileData);
Session::flash('message','Perfil editado com sucesso');
return Redirect::to('backend/perfil');
} else {
return Redirect::to('backend/perfil')->withInput()->withErrors($validation);
}
}
解决方法
问题可能是由于这些原因
'aliases' => [
//add these three at the bottom
'Form' => Illuminate\Html\FormFacade::class,'HTML' => Illuminate\Html\HtmlFacade::class,'Image' => Intervention\Image\Facades\Image::class
],
我相信你已经有了form和html帮助器.
并在Controller中使用此功能
即,只需将图像和大小值作为参数传递给此函数
$resizedImage = $this->resize($image,$request->get('image_size'));
并且resize()函数如下所示
private function resize($image,$size)
{
try
{
$extension = $image->getClientOriginalExtension();
$imageRealPath = $image->getRealPath();
$thumbName = 'thumb_'. $image->getClientOriginalName();
//$imageManager = new ImageManager(); // use this if you don't want facade style code
//$img = $imageManager->make($imageRealPath);
$img = Image::make($imageRealPath); // use this if you want facade style code
$img->resize(intval($size),null,function($constraint) {
$constraint->aspectRatio();
});
return $img->save(public_path('images'). '/'. $thumbName);
}
catch(Exception $e)
{
return false;
}
