Digg This block

Hello,

I've implemented a _block function for the Digg This module on my local version. No need to change any code, just add the following function.

function diggthis_block($op = 'list', $delta = 0, $edit = array()) {
    $blocks = array();

    switch ( $op ) {
        case 'list':
            $blocks[0] = array(
                'info' => t('Digg This'),
                'weight' => 0,
            );
            break;

        case 'view': default:
            // If $op is "view", then we need to generate the block for display
            if ( arg(0) == "node" && is_numeric(arg(1)) ) {
                // Load the node information
                $node = node_load(arg(1));
                $blocks['content'] = theme('diggthis_button', $node);
                $blocks['subject'] = variable_get('diggthis_block_title_'.$delta, t("Digg"));
            }
            break;
      }
      return $blocks;
}

This allows you to place the Digg button any place where a block may be added, in case you don't want it to appear in the node content. To avoid the button from appearing twice, you can uncheck all the node types on the Digg This settings page (admin/settings/diggthis).
