NullPage class

NullPage is a type of Page object returned by many API methods to indicate a non-match.

The simplest way to detect a NullPage is typically by checking the value of the $page->id property. If it happens to be 0 then for most practical purposes, you have a NullPage. A NullPage object has all of the same methods and properties as a regular Page but there's not much point in calling upon them since they will always be empty.

$item = $pages->get("featured=1"); 

if(!$item->id) {
  // this is a NullPage
}

if($item instanceof NullPage) {
  // this is a NullPage
}

“Indeed, if ProcessWire can be considered as a CMS in its own right, it also offers all the advantages of a CMF (Content Management Framework). Unlike other solutions, the programmer is not forced to follow the proposed model and can integrate his/her ways of doing things.” —Guy Verville, Spiria Digital Inc.
