As I descriped earlier here:
http://wordpress.org/support/topic/doesnt-save-custom-field-data-in-media-frame
The issue was fixed but a new problem appeared:
If I do not touch the values in my custom fields it does not save the value of the first option of the selectbox.
The code for my selectbox is here:
/**
* Form fields
*/
function custom_attachment_fields_to_edit( $form_fields, $post ) {
$form_fields['size'] = custom_attachment_fields_to_edit_cb( $post );
return $form_fields;
}
add_action( 'attachment_fields_to_edit', 'custom_attachment_fields_to_edit', 10, 2 );
/**
* Form field callback
*/
function custom_attachment_fields_to_edit_cb( $post ) {
$out_array = array(
'one-col' => __( 'One column' ),
'two-cols' => __( 'Two columns' ),
'full-row' => __( 'Full row')
);
$out = '<select id="attachments-' . $post->ID . '-size" name="attachments[' . $post->ID . '][size]">';
foreach ( $out_array as $k => $v ) {
$selected = selected( $k, get_post_meta( $post->ID, 'attachment_size', true ), false );
$out .= '<option value="' . $k . '"' . $selected .'>' . $v . '</option>';
}
$out .= '</select>';
return array(
'label' => __( 'Size' ),
'input' => 'html',
'html' => $out,
);
}
/**
* Save our gallery meta
*/
function custom_attachment_fields_to_save( $post, $attachment ) {
if( isset( $attachment['size'] ) )
update_post_meta( $post['ID'], 'attachment_size', $attachment['size'] );
return $post;
}
add_filter( 'attachment_fields_to_save', 'custom_attachment_fields_to_save', 10, 2 );
