hello i’m creating a widget with 3 fields, image, title and url, at this moment everything is working like a charm, but when i want to print widget array i got this error in array.

Piklist file

<?php
piklist('field', array(
    'type' => 'group'
    ,'label' => __('Publicidad') 
    ,'add_more' => true
    ,'fields' => array(
      array(
        'type' => 'file'
        ,'field' => 'image',
        'label' => 'Imagen'
      ),
      array(
        'type' => 'text'
        ,'field' => 'titulo',
        'label' => 'Titulo'
      ),
      array(
        'type' => 'text'
        ,'field' => 'url',
        'label' => 'Enlace'
      ),
    )
  ));

Print_r of $settings

Array
(
    [image] => Array
        (
            [0] => 13
            [1] => Array
                (
                    [0] => undefined
                    [1] => 15
                )

            [2] => Array
                (
                    [0] => undefined
                    [1] => 14
                )

        )

    [titulo] => Array
        (
            [0] => title---
            [1] => title---
            [2] => title---
        )

    [url] => Array
        (
            [0] => http:...
            [1] => http:...
            [2] => http:...
        )

)

first array position retrives image id, but second and third no.

Another question, is how can i loop into this array? i want to do this because i need to set random ads and posts.

Thanks!
