I'm validating file uploads in my form and i want to know if it's possible to display a dynamic message using information from the form.

This is my validation model:

public function validationDefault(\Cake\Validation\Validator $validator) {

      ->add('file', array(
          'rule' => ['extension', ['jpeg', 'png', 'jpg']],
          'message' => '[[fileName]] has no valid extension.'          
        'fileSize' => array(
          'rule' => array('fileSize', '<=', '100K'),
          'message' => '[[fileName]] exceed 100K.'),

    return $validator;

I would like to replace the message to show for example: 'document.docx has no valid extension.'

I've read that this can be done with a custom validation, but i'm using proper cakephp validation not custom.

is there a way to do it or it can only be donde with a custom validation??
