I’m working on creating a widget that will have a photo and some text and a title. I’ve set-up the fields like so:

<?php
/*
Width: 420
*/

piklist('field', array(
    'type' => 'text'
    ,'field' => 'tc_widget_title'
    ,'label' => 'Text'
    ,'value' => ''
    ,'help' => 'add the title of the widget area here i.e. Guild Quality or Houzz'
    ,'attributes' => array(
      'class' => 'regular-text'
    )
  ));

  piklist('field', array(
    'type' => 'textarea'
    ,'field' => 'tc_widget_text_area'
    ,'label' => 'Large Code'
    ,'description' => 'class="large-text code" rows="10" columns="50"'
    ,'value' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
    ,'attributes' => array(
      'rows' => 10
      ,'cols' => 50
      ,'class' => 'large-text code'
    )
 
  ));

  piklist('field', array(
    'type' => 'file'
    ,'field' => 'tc_logo_widget'
    ,'label' => __('Add File(s)','piklist-demo')
    ,'description' => __('This is the uploader seen in the admin by default.', 'piklist-demo')
    ,'options' => array(
      'modal_title' => __('Add File(s)', 'piklist-demo')
      ,'button' => __('Add', 'piklist-demo')
    )
    ,'validate' => array(
      array(
        'type' => 'limit'
        ,'options' => array(
          'min' => 0
          ,'max' => 2
        )
      )
    )
  ));

Following the user guide I’ve set-up the display like so

<?php
/*  
Title: Testimonials
*/
?>

<?php echo $before_widget; ?>

  <?php echo $before_title; ?>

  <?php echo $settings['tc_widget_title']; ?>!
  
  <?php echo $after_title; ?>

  <?php echo $settings['tc_widget_text_area']; ?>!

  <?php echo $settings['tc_logo_widget']; ?>!

    
<?php echo $after_widget; ?>

I’m getting an undefined index error for the upload field. Is there some added trick for displaying image fields on the front-end?

Thanks for your help!
