Two things you will need to update:

FORM:
Your scope should be post_meta, because that’s where the data is being saved.
,'scope' => 'post_meta'

You will need to include a hidden field to tell Piklist which CPT to save against:

  piklist('field', array(
    'type' => 'hidden'
    ,'scope' => 'post'
    ,'field' => 'post_type'
    ,'value' => 'shop_order'
  ));

You can see a sample of this in:
plugins/piklist/add-ons/piklist-demos/parts/forms/new-post-with-validation.php

DISPLAY THE DATA:
One of the big changes with v0.9.9x is that you no longer need all that code to retrieve you data. You can easily pull it like a standard PHP array and loop through it.

Try this:

$upload_orders = get_post_meta($post->ID, 'upload_order_attch', false);

foreach ($upload_orders as $upload_order => $value)
{
  echo $value;
}

Let us know if that works for you.

@dougsandlin– In most cases you can use standard WordPress functions to retrieve and manipulate your data with Piklist. One of the goals Kevin and I had when creating Piklist, was not to force users to learn a bunch of new functions.

You can useget_option() with Piklist just like you would use it with any other option.

Glad you figured it out.

Closing ticket.

Great. Closing ticket.

It’s under the standard WordPress settings

Can you post the field code for ‘sponsor’?

@dougsandlin Where do you want to show/use this setting?

get_option is a WordPress function not a Piklist function.

If the setting will control something in your then, then the code will probably go there.

Let us know what you want your setting to do?

This is fixed in the next version of Piklist

In SETTINGS > MEDIA, what dimensions are set for the Thumbnail size?

If empty, please set to 150 and see if that helps.
