Meta Box

Hello Anh Tran, is working with the update thanks for this.

hello, I think I did not correctly share my problem, I'm not talking about the field 'type' => 'image_select', but the field 'type' => 'image', where updating a post is deleted, this happens when using or metabox 4.12.5.

thank you

Complementing, I am using version 4.9 of wordpresss and this only happens with version 4.12.5 of metabox, with version 4.12.4 I do not have the problem presented.

In my tests I edited the inc/core.php file

/**
	 * Register hooks.
	 */
	public function __construct()
	{
		$plugin = 'meta-box/meta-box.php';
		add_filter( "plugin_action_links_$plugin", array( $this, 'plugin_links' ) );
		add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );
		//EDIT init per admin_init
        add_action( 'init', array( $this, 'register_meta_boxes' ) );
        add_action( 'init', array( $this, 'register_wpml_hooks' ) );
        add_action( 'edit_page_form', array( $this, 'fix_page_template' ) );
	}

per

/**
	 * Register hooks.
	 */
	public function __construct()
	{
		$plugin = 'meta-box/meta-box.php';
		add_filter( "plugin_action_links_$plugin", array( $this, 'plugin_links' ) );
		add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );
		//EDIT init per admin_init
        add_action( 'admin_init', array( $this, 'register_meta_boxes' ) );
        add_action( 'admin_init', array( $this, 'register_wpml_hooks' ) );
		add_action( 'edit_page_form', array( $this, 'fix_page_template' ) );
	}

switching to init per admin_init the error disappears

Hi I think that I now had not been tested in this way, let's rephrase my problem then

the metabox plugin is loaded internally in my plugin example

my-plugin> frameworks> meta-box-master

Ie after the last updates the plugin is not being charged with a suplimento another plugin
https://metabox.io/faq/
=================================================
Can I include into my premium plugins themes / plugins?

Yes, absolutely. You can use plugins in your premium, commercial products, but you have to keep credit to me the the author of the plugin.
=================================================

Today I carry the meta-box-master
so in my
require_once plugin ('4.8.7 / meta-box.php');
require_once('mb-settings-page/mb-settings-page.php');
require_once('meta-box-group/meta-box-group.php');
require_once('meta-box-tabs/meta-box-tabs.php');

ie the problem is being load within a plugin

In my tests I edited the inc/core.php file

	/**
	 * Register hooks.
	 */
	public function __construct()
	{
		$plugin = 'meta-box/meta-box.php';
		add_filter( "plugin_action_links_$plugin", array( $this, 'plugin_links' ) );
		add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );
		//EDIT init per admin_init
        add_action( 'init', array( $this, 'register_meta_boxes' ) );
        add_action( 'init', array( $this, 'register_wpml_hooks' ) );
        add_action( 'edit_page_form', array( $this, 'fix_page_template' ) );
	}

PER

	/**
	 * Register hooks.
	 */
	public function __construct()
	{
		$plugin = 'meta-box/meta-box.php';
		add_filter( "plugin_action_links_$plugin", array( $this, 'plugin_links' ) );
		add_action( 'plugins_loaded', array( $this, 'load_textdomain' ) );
		//EDIT init per admin_init
        add_action( 'admin_init', array( $this, 'register_meta_boxes' ) );
        add_action( 'admin_init', array( $this, 'register_wpml_hooks' ) );
		add_action( 'edit_page_form', array( $this, 'fix_page_template' ) );
	}

and edited the file inc / metabox.php

In the master version file has been removed to the lower part

	/**
	 * Get field class name. Only for backward compatibility.
	 * @param array $field Field array
	 * @return string Field class name
	 */
	public static function get_class_name( $field )
	{
		return RWMB_Field::get_class_name( $field );
	}

For me it worked the above modifications
