[Resolved] Add custom field to woocommerce order items

not sure if this is possible. On my site we use woocommerce which has the post type of "orders". The orders table contains details of the items in the order.

On our store orders can be made up of a few items, so when we send the order to the warehouse to pick the items it would be great if, on the orders page, next to each item in the order there was a checkbox "item picked"

i can add post field groups to orders post type, but, that just places a group of fields on the orders page, but, not related to the items in the order.

as i said, dont think this is possible but thought i would ask (as order post type is not created by toolset)

thanks

Exactly, this is how Custom Fields behave generally in WordPress.

You will need to add options on your own to the fields.
This can be done manually by populating the fields in Toolset > Custom Fields, or, it can be done with the API wpt_field_options().
But this is an unofficial API that is not documented and we cannot assist it.

The filter wpt_field_options can be used to manipulate the options of select and radio field.

Arguments:
- $current_options
- $title (the title of the field)

Output: Array

Required format:

array(
    array(
        '#title' => 'First Title',
        '#value' => 'first-value'
    ),
    array(
        '#title' => 'Second Title',
        '#value' => 'second-value'
    ),
)

Example of usage:
Let's assume your theme has a colorset of dark, light and accent color, which are editable in the theme options. The theme stores these values as a wp_option theme_name_colorset in this format:

array(
    'Dark'         => '#333333',
    'Light'        => '#eeeeee',
    'Accent Color' => '#ff3300'
)  

You want to use these colors on a custom select field to define the headline color of the post. So we create a post field group with a select field: See Screenshot

Now we adding this function to our themes functions.php:

add_filter( 'wpt_field_options', function ( $current_options, $title_of_field ) {
    if ( $title_of_field != 'Headline Color' ) {
        // not our "Headline Color" field
        return $current_options;
    }

    $theme_colorset = get_option( 'theme_name_colorset' );

    if ( ! $theme_colorset ) {
        // no theme colors are set yet
        return array(
            array(
                '#title' => 'No colors available',
                '#value' => 0
            )
        );
    }

    $new_options = array();
    foreach ( $theme_colorset as $color_title => $color_value ) {
        $new_options[] = array(
            '#title' => $color_title . ' (' . $color_value . ')',
            '#value' => $color_value
        );
    }

    return $new_options;
}, 10, 2 );
