Displaying only immediate children (only one level) pages using get_pages() function


Displaying only immediate children (only one level) pages in WordPress. For example, I have page and sub page structure like:

Page 1
  Page 11
     Page 111
     Page 112
  Page 12
  Page 13
Page 2
  Page 21
  Page 22
     Page 221
     Page 222

Let’s suppose, you need to list all children pages of Page 1, i.e. Page 11Page 12Page 13. But you don’t want to be listed Page 111Page 112 and so on which is WordPress’s default behavior.

Let us assume that ID of Page 1 is 5 then:

$result = get_pages('child_of=5&hierarchical=0&parent=5);

Notice the child_of and parent must have same value. This function will get only three page – Page 11Page 12Page 13 and not Page 111, Page 112 and so on.

WordPress Pagination without plugin


The default WordPress pagination only comes with the “Older posts” and “Newer posts” links at the bottom of the page when you want to navigate to the older entries. This works fine for sites with few entries, but isn’t very user-friendly for blogs and sites with dozens or even hundreds of pages worth of entries. To enable your visitors to quickly navigate your site and browse through your content from page to page, a list of numbered pages would be more useful, like Google’s search results.

Add the following function to your functions.php file:
