Going to a Random Page in Wordpress

I have a wordpress blog and I want a simple function that allows me to click on a link and take me to a random page on the site. The page url format is http://example.com/page/2/, so I basically need to know how to insert a random number in place of that 2. It also needs to be within the number of pages I have on the site. Any idea how to do this in php/html?

 

Try this. It randomly pulls a parent post ID from the post table and returns just a number.

function get_randompost()
    // randomly pulls a post number from the database
    // returns an integer
    // a database connection must be made prior to executing this function
    {$sql="SELECT ID FROM wp_posts WHERE post_parent=0 ORDER BY RAND() LIMIT 1;"
	return mysql_result(mysql_query($sql), 0, 0);
    }

PHP:

 

PHP has a method for random numbers:

echo rand(5, 15);

This would output a random number between 5 and 15.

Just do:

$randnum = rand(5, 15);
echo "<a href='myblog.com/page/".$randnum."'>Random Link</a>";
