亲爱的StackOverflow社区
我很难弄清楚为什么我的图像验证不能正常工作。我正在验证form :: file（）应该是一个图像，以及400x300像素的大小。为此，我使用了来自cviebrock（https://github.com/cviebrock/image-validator）的模块图像验证器。它认为在重新安装我的操作系统之前它有效，但我不确定，因为我可能会意外地删除或修改了一些好的代码。
我99％肯定我在\ Input：file（'name'）上验证，因为我在验证属性上执行了var转储，该转储应该保存文件。您可以在下面看到这个var转储（来自$ input ['fotofile']的var_dump）：
object(Symfony\Component\HttpFoundation\File\UploadedFile)[9]
private 'test' => boolean false
private 'originalName' => string '400x300real.gif' (length=15)
private 'mimeType' => string 'image/gif' (length=9)
private 'size' => int 1558
private 'error' => int 0
我的验证器类和basevalidator：
<?php
namespace validation;
class NewPostValidator extends BaseModelValidator {
protected $rules = [
"title" => "required|min:10",
"beschrijving" => "required|between:175,1000" ,
"foto" => "required",
"fotofile" => "image|image-size:400,300",
"thumbnailfile"=> "image|image-size:200,150"
];
protected $messages = [
"title.required" => "U heeft geen titel opgegeven.",
"title.min" => "Een titel moet bestaan uit minimum 10 tekens.",
"beschrijving.required" => "U heeft geen beschrijving opgegeven.",
"beschrijving.between" => "Een beschrijving moet uit minimaal 175 en maximaal 1000 tekens bestaan.",
"foto.required" => "U heeft geen foto gekozen.",
"fotofile.image" => "Uw foto is geen afbeelding.",
"fotofile.image-size" => "Uw foto moet 400x300 pixels zijn.",
"thumbnailfile.image" => "Het thumbnailveld bevat geen afbeelding.",
"thumbnailfile.image-size" => "Uw thumbnail moet 200x150 pixels zijn."
];
}
在我的UserRepository类中处理输入之前，我使用静态fetchinput方法重新排序Input。我知道这不是100％干净的代码，但我还是学生，所以我还在学习：
<?php
namespace InputFetcher;
use InputFetcher\InputFetcher;
class PostFetcher implements InputFetcher {
public static function fetchInput( $input ){
if(!$input['update']){
$input['id'] = null;
}
$post = \Post::where('id', '=', $input['id'])->get();
$now = new \DateTime("now");
if(null !== \Input::file('foto')){
$foto = \Input::file('foto');
$input['foto'] = "/images/" . $now->format('Y-m-d') . $foto->getClientOriginalName() ;
$input['fotofile'] = $foto;
} else if($input['update']) {
$input['foto'] = $post[0]->foto;
}
if(null !== \Input::file('thumbnail')){
$thumb = \Input::file('thumbnail');
$input['thumbnail'] = "/images/" . $now->format('Y-m-d') . $thumb->getClientOriginalName();
$input['thumbnailfile'] = $thumb;
} else if($input['update']) {
$input['thumbnail'] = $post[0]->thumbnail;
}
$input['userid'] = \Auth::user()->id;
return $input;
}
}
当我发布表单时，我收到一个显示验证错误的响应，因为该文件不是图像，大小不是400x300像素。
我一直在搜索网络和stackoverflow几个小时，所以我真的非常渴望这个工作。如果问题不在我的代码中：我已经将模块从cviebrock添加到我的composer.json并通过我的终端更新了它。

感谢您的时间。
Ps：抱歉，如果我的英语不好。
Ps *：我认为你们也可以添加我的PostRepository类的代码。方法make（$ input（它是\ Input :: all（））由我的PostController调用并在那里返回一个响应。
<?php
namespace Repository;
use InputFetcher\PostFetcher;
use Exceptions\ValidationException;
use validation\NewPostValidator;
class PostRepository extends BaseRepository {
protected $validators = [
'newpost' => 'NewPostValidator'
];
public function __construct( \Post $postModel ){
$this->model = $postModel;
}
public function make ( $input ){
$this->validator = \App::make( $this->getValidator( 'newpost' ) );
$input['update'] = false;
$input = PostFetcher::fetchInput( $input );
$foto = \Input::file('foto');
$thumb = \Input::file('thumbnail');
$now = new \DateTime('now');
if( null!==$foto ){
$foto->move('images', $now->format('Y-m-d') . $foto->getClientOriginalName());
}
if( null!==$thumb ){
$thumb->move('images', $now->format('Y-m-d') . $thumb->getClientOriginalName());
}
$result = parent::make($input);
if( null!==$this->messageBag ){
throw new ValidationException( implode( "&", $this->messageBag ) );
}
return $result;
}
public function update ( $id, $input ){
$this->validator = \App::make( $this->getValidator( 'newpost' ) );
$input['id'] = $id;
$input['update'] = true;
$input = PostFetcher::fetchInput( $input );
$foto = \Input::file('foto');
$thumb = \Input::file('thumbnail');
$now = new \DateTime('now');
if( null!==$foto ){
$foto->move('images', $now->format('Y-m-d') . $foto->getClientOriginalName());
}
if( null!==$thumb ){
$thumb->move('images', $now->format('Y-m-d') . $thumb->getClientOriginalName());
}
$result = parent::update( $id, $input );
if( null!==$this->messageBag ){
throw new ValidationException( implode( "&", $this->messageBag ) );
}
return $result;
}
public function findAll(){
$posts = \DB::table('posts')
->leftJoin('user', function( $join ){
$join->on( 'posts.userid', '=', 'user.id' );
})
->orderby( 'created_at', 'desc' )->paginate('5', array( 'posts.id', 'posts.article', 'posts.beschrijving',
'posts.title', 'user.naam', 'user.voornaam',
'posts.foto', 'posts.thumbnail', 'posts.created_at',
'posts.challenge' ) );
return $posts;
}
public function find( $id ){
$post = parent::find( $id );
$author = \DB::table( 'user' )->join('posts', 'user.id', '=', 'posts.userid')
->where('posts.id', '=', $id)->get( array('naam', 'voornaam') );
return array( 'post' => $post , 'author' => $author );
}
public function postOverview(){
return \DB::table('posts')->get();
}
}
P.S。 **：这是验证器对象的var转储

答案 0 :(得分：2)
我发现了错误，所以如果有人需要这个，我就发帖了。显然，您必须在将图像移动到文件夹之前对其进行验证。移动图像时，临时文件夹不再保留图像。
