hi, here is a rookie question. I want to split $content output before it were return by page callback function which declared by hook_menu, so that allow me to print directly $content_top and $content_main at page.tpl.php file. Meanwhile, $content_top and $content_main were generated by different function. I found 2 approach to make it happen, First one is using modulename_preprocess_page to declare variables before it were passed to template file. It works fine. e.g. $var['$content_top']=function_name(); Second one is that split the content into many blocks, taking the advantages of block visibility setting option to control the appearance of regions based on the '?q=' path.It works fine too. Any one know better approach to solve the problem? Thanks Wang
