I have created a simplified version of it helpfunc <- function(mean, sd) { hist(rnorm(1000, mean, sd))

问题 I want to pull the content of a CMS page into my static block, if you know of a way to do this I would be grateful. 回答1: Haven't tested this, but it should work. If you have the unique ID of the cms page (not the identifier): $page = Mage::getModel('cms/page'); $page->setStoreId(Mage::app()->getStore()->getId()); $page->load($pageId); Otherwise if you have the page's identifier (i.e. URL key), use something like this: $urlKey = "url_key"; $page->load($urlKey,'identifier'); Then finish with:
