Hej. Sorry for my english. I have a problem with custom fields in widget. I create fields, but i haven’t save data. This problem view in this video https://youtu.be/vvNFAVXDk9Q. And my test code:

<?php 
class CustomWidget extends WP_Widget {
	function __construct() {
		parent::__construct(
			'custom_widget', // Base ID
			__('CustomWidget', 'text_domain'), // Name
			array( 'description' => __( 'Some CustomWidget', 'text_domain' ), ) 
		);
	}
	public function form( $instance ){
		?>
		<p></p>
		<?php
	}
	public function widget( $args, $instance ) {
		$title = apply_filters( 'widget_title', $instance['title'] );
		  
		// before and after widget arguments are defined by themes
		echo $args['before_widget'];
		if ( ! empty( $title ) )
		echo $args['before_title'] . $title . $args['after_title'];
		  
		// This is where you run the code and display the output
		?>
		<a href="test"><?php var_dump(get_field('dzialaj','widget_' . $args['widget_id']))?></a>
		<?php
		echo $args['after_widget'];
		}
}
 
// register Foo_Widget widget
function register_foo_widget() {
    register_widget( 'CustomWidget' );
}
add_action( 'widgets_init', 'register_foo_widget' );

How fix it.

Hey @matib12 and @endcore.

We’ve just released ACF 5.10 which includes a fix for this issue! Please let me know if you continue to have any problems after updating.

@lgladdy
I use locally
Wordpress 5.8.1
ACF version 5.10.2
Advanced Custom Fields Multilingual 1.9.1
WPML Media 2.6.5
WPML Multilingual CMS 4.4.12
WPML String Translation 3.1.10
WPML Translation Management 2.10.8.

When I save my custom widget, the widget get the ID media_widget-1
but the saved options receive the ID widget_media_widget-12

Workflow:

1. Add Custom Widget
2. Fill out loaded ACFs
3. ID is<input class="widget-id" type="hidden" name="widget-id" value="media_widget-12"><– maybe the ID should be 1 not 12
4. Click on Update
5. Reload the page
6. After reloading the Gutenberg the id has changed to media_widget-1:<input class="widget-id" type="hidden" name="widget-id" value="media_widget-1">

Hope this will help.

+ The ID in the frontend differs to the widget ID in backend:

class custom_Media_Widget extends WP_Widget
{

    /**
     * @param string $idBase
     * @param string $name
     * @param array  $widgetOptions
     * @param array  $controlOptions
     */
    public function __construct(
        string $idBase = 'media_widget',
        string $name = 'Media Asset Widget',
        array $widgetOptions = [],
        array $controlOptions = []
    ) {
        $widgetOptions ['classname']   = 'media_widget';
        $widgetOptions ['description'] = 'Widget for Media Assets';

        parent::__construct($idBase, $name, $widgetOptions, $controlOptions);
    }

    public function widget($args, $instance)
    {
        var_dump($args['widget_id']);
        //....
    }
}

will output: string 'media_widget-3' (length=14)

Edit: The id/number which is set in the backend isn’t relevant anymore.
I test it on the meta widget and it show the same behaviour.

ID: meta-13 on save
ID: meta-2 in frontend
