Laravel-文件的自定义验证不起作用

Question

I am trying to use custom validation rules for file inputs in Laravel. The file input name is "photo". I am trying to apply a rule called "validate_art", to this file input. I know there's "image" validation rule, but I want to apply my own customized rule to this file input.

Here's the code :

  $rules = array('name'=>'required|unique:user,name','startyear'=>'numeric','endyear'=>'numeric'
    ,'photo'=>'validate_art');
    Validator::extend('validate_art',function($attribute,$value,$parameters){
    // returning false just for testing purpose
    return false;
    });

What happens is, it doesn't apply the rule to the field at all. When I try to use this rule to some other field for testing purposes, it works without failure. Am I doing something wrong? Or custom validation cannot be applied for file inputs? Please someone, throw some light at this. I would really appreciate that.

first you should modify your input data

    foreach ($inputs as $k=>$input){
        if($input instanceOf \Symfony\Component\HttpFoundation\File\UploadedFile)
            $inputs[$k]=$_FILES[$k];
    }

then send $input to validator $validator=Validator::make($input,$rules)
