Hello everyone,

I've a problem with my filemanager in my edit_form.php. 

To save the data I use the function instance_config_save in my block_like.php :

public function instance_config_save($data, $nolongerused = false) {
    $config = clone $data;
    if (isset($config->likes_pix)) {
        $config->likes_pix = file_save_draft_area_files(
            $data->likes_pix,
            $this->context->id,
            'block_like',
            'likes_pix',
            0
        );
    }
    parent::instance_config_save($config, $nolongerused);
}

The problem is that when I save a new config without giving any file, the old one are deleted, the solution is to load the old files in the filemanager but anything I'm trying don't works... I tried the set_data function in my edit_form.php but I don't really know how to use it :

public function set_data($defaults) {
    $filemanageropts = array('subdirs' => 0, 'maxbytes' => 0, 'maxfiles' => 50);
    $itemid = 0;
    $draftitemid = file_get_submitted_draft_itemid('likes_pix');
    file_prepare_draft_area(
        $draftitemid,
        $this->block->context->id,
        'block_like',
        'likes_pix',
        $itemid,
        $filemanageropts
    );
    $defaults->likes_pix = $draftitemid;
    parent::set_data($defaults);
}

Some ideas to help me ?
