image_advanced field inside group disappears on save

[sebgrey]

Hi,
I am running Wordpress 4.5.3, Meta Box 4.8.7 and Meta Box Group extension 1.1.3. Recently I have experienced issues with using image_advanced field types inside groups: if another field inside the group is edited and the page is saved, the value of the image field disappears. The meta value row is deleted altogether from the database. I would hugely appreciate advice and/or a fix.

I think i'm having the same problem. This seems to fix it:

Same issue here, tried your code but it doesn't work. Running wp 4.8.3 and the latest version of all metabox.io

Hi,

Can you please post your code to create meta boxes?

[alberto-marin]

<?php

$meta_boxes[] = array(
		"id" => "boardmembers",
		"title" => esc_html__( "Board Members", "metabox-online-generator" ),
		"post_types" => array( "page" ),
		"context" => "advanced",
		"priority" => "default",
		"autosave" => true,
    "show" => array(
      // With all conditions below, use this logical operator to combine them. Default is "OR". Case insensitive. Optional.
      "relation" => "OR",
      // List of page templates (used for page only). Array. Optional.
      "template" => array( "page-about-meet-the-board.php"),
		),
		"fields" => array(
      array(
				"id"     => "members_group",
				// Group field
				"type"   => "group",
				// Clone whole group?
				"clone"  => true,
				// Drag and drop clones to reorder them?
				"sort_clone" => true,
				// Sub-fields
        "group_title" => "Member {#}",
        "collapsible" => true,
				"fields" => array(
    			array(
    				"id" => "{$prefix}member_image",
    				"type" => "image_advanced",
    				"name" => esc_html__( "Members", "metabox-online-generator" ),
    				"desc" => esc_html__( "Add member image", "metabox-online-generator" ),

    			),
    			array(
    				"id" => "{$prefix}member_name",
    				"type" => "text",
    				"name" => esc_html__( "Name", "metabox-online-generator" ),
    				"desc" => esc_html__( "Add First and Second Name", "metabox-online-generator" ),
    			),
    			array(

    			),
          array(

            ),
    				"name" => esc_html__( "Job Description", "metabox-online-generator" ),

    			),
    		),
      ),
    ),
  );
?>

Then on my functions.php

<?php
add_filter( 'rwmb_meta_boxes', 'xxx_metaboxes' );

function xxx_metaboxes( $meta_boxes ) {
  $prefix = '_dd_';

  include_once('metaboxes/metabox_frontimage.php');
  include_once('metaboxes/metabox_address.php');
  include_once('metaboxes/metabox_members.php');
  include_once('metaboxes/metabox_products.php');
  include_once('metaboxes/metabox_partners.php');
  include_once('metaboxes/metabox_display_homepage_sections.php');
  include_once('metaboxes/metabox_img_mobile.php');
  include_once('metaboxes/metabox_slider.php');
  include_once('metaboxes/metabox_wysiwyg_with_image.php');
  include_once('metaboxes/metabox_quotes.php');
  include_once('metaboxes/metabox_press_news_image.php');

    return $meta_boxes;
  }
?>
