Hi

I want to use metabox plugin for adding woocommerce products...

I need to add woo product image gallery with metabox image fields.

WooCommerce uses _product_image_gallery custom field to store the image gallery. It stores those images/attachments IDs separated by comma. Ex: 32,34,3874 in that single custom field.

So i need to save the image IDs to the WooCommerce's _product_image_gallery meta key when i publish/update product. Also i need to do this with front-end form submission extension.

I can do this with another plugin with a snippet. Here i share the code for that:
```
/**
* Update the custom field when the form submits
*
* @param type $post_id
*/
function wpuf_woo_product_gallery( $post_id ) {
if ( isset( $_POST['wpuf_files']['_product_image'] ) ) {

$images = get_post_meta($post_id, '_product_image' );
update_post_meta( $post_id, '_product_image_gallery', implode(',', $images) );
}
}

add_action( 'wpuf_add_post_after_insert', 'wpuf_woo_product_gallery' );
add_action( 'wpuf_edit_post_after_update', 'wpuf_woo_product_gallery' );
```
Can do this with metabox ? Can you share a snippet for doing this with metabox if possible ? Sorry that i am not a developer.

Thanks

Yes, it's possible. You need to:

- Register a field with id _product_image_gallery
- Filter to the value when saving to the database
- Filter to the value when outputting the field

This is the sample code. Please try.
```
add_filter( 'rwmb_meta_boxes', function ( $meta_boxes ) {
	$meta_boxes[] = [
		'title'      => 'Save gallery as CSV',
		'post_types' => 'product',
		'fields'     => [
			[
				'type' => 'image_advanced',
				'id'   => '_product_image_gallery',
			],
		],
	];
	return $meta_boxes;
} );

add_filter( 'rwmb__product_image_gallery_value', function ( $value ) {
	$value = implode( ',', $value );
	return $value;
} );
add_filter( 'rwmb__product_image_gallery_field_meta', function ( $meta ) {
	if ( is_string( $meta ) ) {
		$meta = explode( ',', $meta );
	}
	return $meta;
} );
```
