gistfile1.php

<?php
$my_page_type = 'php_news';

$hide_from_nav = TRUE;

$parent = Page::getByPath($parent_path);

/**
* Let's pretend the title and description have been set by POST values

/**
 * Other values possible in data are:
 *  "uID": User ID of the page's owner
    "pkgID": Package ID the page belongs to
    "cName": The name of the page
    "cHandle": The handle of the page as used in the path
    "cDatePublic": The date assigned to the page
 **/

if(is_object($parent) && is_numeric($parent->cID)) $p = $parent->add($ct, $data);

// We can add attributes
if($hide_from_nav){
// Collection Attribute Key Exclude from Navigation
  $cakExNav 	= CollectionAttributeKey::getByHandle('exclude_nav');		
  $cakExNav->setAttribute($p, true);	
}

// You can now add block content
$bt = BlockType::getByHandle('content');
$pdata = array('content' => $content);
