Dont know if is bug or not.

When using:


add_filter('attachment_fields_to_edit', array($this, 'multi_field'), 10, 2);
add_filter('attachment_fields_to_save', array($this, 'multi_field_save'), 10, 2);

function multi_field($form_fields, $post) {
    $current = "something";
    $html = "<select name='attachments[{$post->ID}][multi_field]' id='attachments[{$post->ID}][multi_field]' multiple='multiple'>";
    $html .= "<option value='' " . selected($current, '', false) . ">none</option>";
    $html .= "<option value='a' " . selected($current, $something, false) . ">a</option>";
    $html .= "<option value='b' " . selected($current, $something, false) . ">b</option>";
    $html .= "<option value='c' " . selected($current, $something, false) . ">c</option>";
    $html .= "<option value='d' " . selected($current, $something, false) . ">d</option>";
    $html .= '</select>';

    $form_fields['woosvi-slug'] = array(
        'label' => 'Variation',
        'input' => 'html',
        'html' => $html,
        'application' => 'image',
        'exclusions' => array(

    return $form_fields;

function multi_field_save($post, $attachment) {

    if (isset($attachment['multi_field']))
        update_post_meta($post['ID'], 'multi_field', $attachment['multi_field']);

    return $post;

Each time the select option is done, it runs ajax and saves the last value and not multiple values.
May be im missing somehting to allow this to work properly.
