Post meta boxes loose content when Post is saved as a draft

Hi Alex,

The issue occurs on the clean WP installation only with Site Origin Page Builder and Widgets Bundle installed.
Also tried on few different installations of WP which are on a different servers.
Here are steps to replicate the issue:

1. Go into ‘Custom post type’ -> Add new (custom post type that has Widgets Bundle Post Meta Data fields associated)
2. Add data into any fields and click on ‘Save as draft’ at the top in Publish right hand side menu.
3. All data will disappear from Widget Bundle Post Meta Data fields

.

Thanks,
Olga

Hi Alex,

I add Custom post type using the following function in functions.php:

register_taxonomy_for_object_type('category', 'event'); // Register Taxonomies for Category
//register_taxonomy_for_object_type('post_tag', 'event');
register_post_type('event', // Register Custom Post Type
    array(
        'labels' => array(
            'name' => __('Event', 'event_theme'), // Rename these to suit
            'singular_name' => __('Event', 'event_theme'),
            'add_new' => __('Add New', 'event_theme'),
            'add_new_item' => __('Add New Event', 'event_theme'),
            'edit' => __('Edit', 'event_theme'),
            'edit_item' => __('Edit Event', 'event_theme'),
            'new_item' => __('New Event', 'event_theme'),
            'view' => __('View Event', 'event_theme'),
            'view_item' => __('View Event', 'event_theme'),
            'search_items' => __('Search Event', 'event_theme'),
            'not_found' => __('No Events found', 'event_theme'),
            'not_found_in_trash' => __('No Events found in Trash', 'event_theme')
        ),
        'public' => true,
        'hierarchical' => true, // Allows your posts to behave like Hierarchy Pages
        'has_archive' => true,
        'rewrite' => array(
            'with_front' => false
        ),
        'supports' => array(
            'title',
            'editor',
            'excerpt',
            'thumbnail'
        ), // Go to Dashboard Custom HTML5 Blank post for supports
        'can_export' => true, // Allows export in Tools > Export
        'taxonomies' => array(
            'post_tag',
            'category',
            'office'
        ) // Add Category and Post Tags support
    ));

Then I add a custom widget in \wp-content\plugins\so-widgets-bundle\widgets\.
In the php file where variables defined I would add the following using this functionality: https://siteorigin.com/docs/widgets-bundle/advanced-concepts/post-meta-box-forms/

<?php
/*
Widget Name: Konstructive Event Details
Description: Event details

*/

class Konstructive_Event_Details extends SiteOrigin_Widget {
	function __construct() {

		parent::__construct(
			'konstructive-event-details',
			__('Konstructive Event Details', 'Konstructive Widgets Suite'),
			array(
				'description' => __('Event details', 'Konstructive Widgets Suite')
			),
			array(

			),
			false,
			plugin_dir_path(__FILE__)
		);

	}

	function initialize() {
		global $sow_meta_box_manager;
		$sow_meta_box_manager->append_to_form(
			$this->id_base,
			array(

			'event_link_url' => array(
				'type' => 'link',
				'label' => __('Event Link URL', 'konstructive-widgets-suite'),
				'description' => __('Event CTA, can be used for Register link. Please choose link destination or enter absolute URL', 'konstructive-widgets-suite')
			),

			'event_link_text' => array(
				'type' => 'text',
				'label' => __('Event Link Text', 'konstructive-widgets-suite'),
				'description' => __('Event CTA, can be used for Register link. Please specify link text', 'konstructive-widgets-suite')
			),

			// Event start date and time
		    'event_date' => array(
				'type' => 'text',
				'rows' => 4,
				'label' => __('Event Date', 'konstructive-widgets-suite')
			),

			// Event date and time
		    'event_time' => array(
				'type' => 'text',
				'rows' => 4,
				'label' => __('Event Time', 'konstructive-widgets-suite')
			),

		    // Event location
		    'event_location' => array(
				'type' => 'tinymce',
				'rows' => 4,
				'label' => __('Event Location', 'konstructive-widgets-suite')
			),

		    // Google Map location URL
			'event_google_map_url' => array(
				'type' => 'link',
				'label' => __('Google Map URL', 'konstructive-widgets-suite'),
				'description' => __('Please enter full URL to Google Map location')
			),

		),
			array( 'event' )
		);
	}

	function get_template_variables( $instance, $args ) {
		// Return data to the template
		return array(
			'id_base' => $this->id_base,
			'event_link_url' => $instance['event_link_url'],
			'event_link_text' => $instance['event_link_text'],
			'event_date' => $instance['event_date'],
			'event_time' => $instance['event_time'],
			'event_location' => $instance['event_location'],
			'event_google_map_url' => $instance['event_google_map_url']
		);
	}

}

siteorigin_widget_register('konstructive-event-details', __FILE__, 'Konstructive_Event_Details');

Here is how it looks in the wp-admin: http://cs-pub.konstructive.com/test/Meta-boxes-SO.jpg
So Meta boxes content added using code above would loose all content when saving Event post as a draft.

Please let me know if you need any more details.

Thanks,
Olga
