 * I don’t get how to achieve a filtering function with wp_query. I have three links
   on top of my loop to let the user choose between showing 25, 40 or 80 posts per
   page. I don’t get how to make the clicked link fire the function to show the 
   amount in the loop. Sorry for my bad english. If you don’t understand I will 
   explain it better. Please help me with this one 🙂

 * The links need to call the page with the proper number as an argument to the 
   link, something like this:
 *     ```
       <a href="http://mysite.com/my-page/?perpage=25
       ```
   
 * Then in the code for the template check for the perpage argument and re-issue
   the query using that as the posts_per_page value.
 * You will also need to alter the links generated by the pagination to include 
   the perpage value in order to pass it along to all subsequent pages.
 * The exact coding is probably too involved for this forum. You can post a job 
   request on [jobs.wordpress.net](http://jobs.wordpress.net) at no cost.
