public function WebformConditionals::pageVisibility in Webform 7.4

Returns whether a given page should be displayed.

This requires any conditional for the page itself to be shown, plus at least one component within the page must be shown too. The first and preview pages are always shown, however.

Parameters

int $page_num: The page number that the component is on.

Return value

int self::componentHidden or ...Shown.

Code

public function pageVisibility($page_num) {
  $result = self::componentHidden;
  if ($page_num == 1 || empty($this->visibilityMap[$page_num])) {
    $result = self::componentShown;
  }
  elseif (($page_map = $this->pageMap[$page_num]) && $this
    ->componentVisibility(reset($page_map), $page_num)) {
    while ($cid = next($page_map)) {
      if ($this
        ->componentVisibility($cid, $page_num) != self::componentHidden) {
        $result = self::componentShown;
        break;
      }
    }
  }
  return $result;
