Child Posts are also linked with translation

Hi there,

I have found a solution and sharing it here, it might save someone else time.

Add the following to your functions.php

add_action( 'msls_main_save', 'my_msls_main_save', 1000, 2 );
function my_msls_main_save($object_id, $class){

      $forbidden_post_types = array('array of post type(child) that you want to exclude');
      if (in_array( get_post_type( $object_id ),$forbidden_post_types)) {
        return;
      } 

			$blogs    = MslsBlogCollection::instance();
			$language = $blogs->get_current_blog()->get_language();
			$msla     = new MslsLanguageArray( my_get_input_array( $object_id ) );
			$options  = new $class( $object_id );
			$temp     = $options->get_arr();

			if ( 0 != $msla->get_val( $language ) ) {
				$options->save( $msla->get_arr( $language ) );
			}
			else {
				$options->delete();
			}

			foreach ( $blogs->get() as $blog ) {
				switch_to_blog( $blog->userblog_id );

				$language = $blog->get_language();
				$larr_id  = $msla->get_val( $language );

				if ( 0 != $larr_id ) {
					$options = new $class( $larr_id );
					$options->save( $msla->get_arr( $language ) );
				}
				elseif ( isset( $temp[ $language ] ) ) {
					$options = new $class( $temp[ $language ] );
					$options->delete();
				}
				restore_current_blog();
			}

  }

my_get_input_array( $object_id ) {
		$arr = array();

		$current_blog = MslsBlogCollection::instance()->get_current_blog();
		if ( ! is_null( $current_blog ) ) {
			$arr[ $current_blog->get_language() ] = (int) $object_id;
		}

		$input_post = filter_input_array( INPUT_POST );
		if ( is_array( $input_post ) ) {
			foreach ( $input_post as $key => $value ) {
				if ( false !== strpos( $key, 'msls_input_' ) && ! empty( $value ) ) {
					$arr[ substr( $key, 11 ) ] = (int) $value;
				}
			}
		}

		return $arr;
	}

Hope this will help

Interesting! I never used the plugin you mentioned before. Maybe this is helpful indeed.

Cheers,
