在laravel中插入数据库之前如何验证图像尺寸 [英] how to validate image dimension before insert into database in laravel

问题描述

我是laravel .im中的新手，试图验证图像的尺寸.我要使用controller.php中的验证代码来最小尺寸(宽度= 100，高度= 50).iam 'galimg'=>'required | max:200kb | DimensionMin(300,300)| Mimes:jpeg，jpg，gif，png ，pneg'
但是DimensionMin(300,300)不起作用....我认为自定义验证规则是可能的..但是我不知道如何使用它?在哪里使用?这是我的controller.php代码

Iam new in laravel .im trying to validate dimensions of image .i want dimensions minimum(width=100,height=50).iam using validation code in controller.php is here 'galimg'=>'required|max:200kb|DimensionMin(300,300)|Mimes:jpeg,jpg,gif,png ,pneg'
but DimensionMin(300,300) is not work....i think custom validation rule is possible ..but i dont know how to use it ?and where ? this is my controller.php code

public function getgallery()
  {
    $validate=Validator::make(Input::all(),array(
    'galname'=>'required|max:20',
     'galimg'=>'required|max:400kb|Dimensionmin(300,300)|Mimes:jpeg,jpg,gif,png
                     ,pneg'));
    if($validate->fails())
     {  return Redirect::route('getgallery')
        ->withErrors($validate)->withInput(); }
    else
    { $max_image = 3;
    if(ForumGallery::all()->count() < $max_image)
     {  $file=Input::file('galimg');
        $filename=$file->getClientOriginalName();
     $file->move('uploads',$filename);
     ForumGallery::create(['galname'=>Input::get('galname'),
           'galimg'=>$filename]);
     return Redirect::route('addgallery'); 
      }
    else
     {return Redirect::route('gallery')
      ->with('success','Max Image Upload Reached!');
     } }}

推荐答案

您可以使用这个很棒的库来检测图像尺寸

You can use this awesome library for detecting your image dimension here

安装完成后，您可以像这样在控制器中使用它:

afte done installing you can use it in your controller like this one :

$validate=Validator::make(Input::all(),array(
  'galname'=>'required|max:20',
  'galimg'=>'required|mimes:jpeg,jpg,gif,png,pneg|image_size:1200,800'));

规则应为1200宽，800高或宽度= 1200且高度= 800

the rules should be 1200 wide and 800 tall or width = 1200 and height = 800

注意:尺寸以像素为单位 希望对您有帮助.
