How to solve the problem of validation in Yii2?

Question

Yii

Hello!
I have one problem.
the problem is that when submitting the form does not skip an application that does not have the require attribute
, when clicking on the submit, it will simply ask you to upload a file (but I don’t need it, you need to validate if you uploaded a file, and if you didn’t upload it, you just need to skip it) how to do this?

public $uploadFile;
  public function rules(){
    return [
      [['id','date','phone'], 'integer'],
      [['name','phone'], 'required'],
      [['name'], 'string', 'max' => 20],
      [['company','file'], 'string', 'max' => 255],
      [['uploadFile'], 'file', 'skipOnEmpty' => false, 'extensions' => 'pdf, cdr, zip, rar'],
    ];
  }

uploadFile - not in the database... this is necessary to validate the file
when submitting it should not check if the file is not uploaded
(sorry for errors)

Answer 1

'skipOnEmpty' => false,
change to
'skipOnEmpty' => true
