$page->numDescendants() method

Return number of descendants (children, grandchildren, great-grandchildren, …), optionally with conditions

Use this over the $page->numDescendants property when you want to specify a selector or apply some other filter to the result (see options for $selector argument). If you want to include only visible descendants specify a selector (string or array) or boolean true for the $selector argument, if you don’t need a selector.

If you want to find descendant pages (rather than count), use the Page::find() method.

Example

// Find how many descendants were modified in the last week
$qty = $page->numDescendants("modified>='-1 WEEK'");

Usage

// basic usage
$int = $page->numDescendants();

// usage with all arguments
$int = $page->numDescendants($selector = null);

Arguments

selector (optional)

Return value
