1. 记录每个帖子的访问人情况

								require_once("block.MTHasSubCategories.php");				function smarty_block_MTHasNoSubCategories($args, $content, &$ctx, &$repeat) {				    $localvars = array('conditional','else_content');								    if (!isset($content)) {				        $ctx->localize($localvars);				        $has_no_sub_cats = !_has_sub_categories($ctx);				        $ctx->stash('conditional', $has_no_sub_cats);				        $ctx->stash('else_content', null);				    } else {				        if (!$ctx->stash('conditional')) {				            $content = $ctx->stash('else_content');				        }				        $ctx->restore($localvars);				    }				    return $content;				}				?>
