[TYPO3-mvc] validator too greedy, conditional validation?

[Andrea Schmuttermair]

You could add a hidden field, and set the value to 1 at submit of an  
upload, for example by javascript at "Submit"?

Or just check if there is a upload file, if yes do your operation, if  
not skip.

  public function isValid($value) {
     $this->errors = array();

     if (isset($_FILES['tx_myext_file'])) {
       ...do your upload stuff
     }

     if (count($this->errors) > 0) {
       return false;
     }

     return true;
  }

If there are too much problems, a redesign of your  
Controller/Action/Validator logic might be usefull.
Upload operations in the validator are not the idea of validation.
In the Controller, you can add another Action "uploadAction" and  
redirect from one action to another, depending on the upload status:

if ($thereWasAnUpload) {
              
$this->redirect('upload','controllername','myext',array('params' =>  
$params);
         } else {
             ...
         }

Andrea
