Dear all!

I’m glad to use piklist plugin and very apprieciative for your job.
I’ve encountered the problem after upgrading to v.0.9.9.9 .
Please look at the code below.
11th line indicates an error

Invalid argument supplied for foreach()

.

foreach ($fields[$key][‘request_value’] as $id)

add_action( 'piklist_save_field', 'my_save_post', 10, 2 );

function my_save_post($scope, $fields) {
        global $wpdb;
        if ($scope == 'relate-reverse')
        {
                foreach ($fields as $key => $value)
                {
                        if (substr_compare($key, '_relate_id', -strlen('_relate_id'), strlen('_relate_id')) === 0)
                        {
                                foreach ($fields[$key]['request_value'] as $id)
                                {
                                        foreach ($fields as $key => $value)
                                        {
                                                if (substr_compare($key, '_post_id', -strlen('_post_id'), strlen('_post_id')) === 0)
                                                {
                                                        foreach ($fields[$key]['request_value'] as $post_ids)
                                                        {

                                                                {
                                                                                PikList_Form::relate($post_id, array($id));
                                                                }

                                                }

                                                if (substr_compare($key, '_relate_remove', -strlen('_relate_remove'), strlen('_relate_remove')) === 0)

                                                        foreach ($remove as $has)
                                                        {

                                                                }
