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 11, Page 12, Page 13. But you don’t want to be listed Page 111, Page 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 11, Page 12, Page 13 and not Page 111, Page 112 and so on.
by using extract() function, we can create variables with associative arrays elements
varaible names are element keys and variable values are element values
<?php $arr=array('x'=>10,'y'=>20,30,'abc'=>'scott'); extract($arr); echo $x; //10 echo $y; //20 echo $abc; //scott ?>
