Question

I have the following code that shows 5 posts each being the latest from an author. Want I want to do is show the these 5 posts in a random order so that no author gets precedence over the other. To clarify this is the ordering of these 5 posts and NOT the posts of the author. Thanks

code:

<?PHP

  get_header();

 ?>


 <script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.masonry.js"></script>
 <script type="text/javascript">
  jQuery(document).ready(function(){
   $('#post-list').masonry({ singleMode: true, itemSelector: 'article', animate: false });
  });
 </script>

 <?php

  function MyLoopCode()
  {
 ?>

 <article id="post-<?php the_ID(); ?>">

  <div class="post-image"></div>

  <div class="post-text">

  <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

  <p class="p-cat">In: <?php the_category('|') ?></p>

  <p class="p-author">
   <span class="name"><?php the_author_posts_link(); ?></span>
   <span class="avatar"><a title="View posts by <?php the_author(); ?>" href="<?php echo get_author_posts_url($authordata->ID); ?>"><?php echo get_avatar( $email, $size = '64' ); ?></a>
   </span>
  </p>


  <small class="p-time">

Answer 1

Summary:
1. Get output of MyLoopCode() as an array.
2. Shuffle the array.
3. Display contents.

---

Implementation:

1) Return the output of MyLoopCode() using ob_start() and ob_get_clean() & store it in an array.

Explanation: The ob_start() starts output caching so instead of sending the output to the browser the PHP will keep the output in its buffer. Then, at the end of the function, by using ob_get_clean(), we tell PHP to give use the output as a string and delete from its buffer. So, the function now returns the contents that would be otherwise outputted to the browser by the MyLoopCode() function.

<?php
 function MyLoopCode()
  {
ob_start();
 ?>

 <article id="post-<?php the_ID(); ?>">

  <div class="post-image"></div>

  <div class="post-text">

  <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

  <p class="p-cat">In: <?php the_category('|') ?></p>

  <p class="p-author">
   <span class="name"><?php the_author_posts_link(); ?></span>
   <span class="avatar"><a title="View posts by <?php the_author(); ?>" href="<?php echo get_author_posts_url($authordata->ID); ?>"><?php echo get_avatar( $email, $size = '64' ); ?></a>
   </span>
  </p>


  <small class="p-time">
  <strong class="day"><?php the_time('j') ?></strong>
  <strong class="month"><?php the_time('M') ?></strong>
  <strong class="year"><?php the_time('Y') ?></strong>
  </small>

  <section class="content">
   <?php the_content('<p>Read the rest of this page &raquo;</p>'); ?>
  </section>

  <div class="p-det">
   <p class="p-det-com"><?php comments_popup_link('No Comments', '(1) Comment', '(%) Comments'); ?></p>
   <?php if (function_exists('the_tags')) { ?> <?php the_tags('<p class="p-det-tag">Tags: ', ', ', '</p>'); ?> <?php } ?>
  </div>

  </div>

 </article>

 <?php
  return ob_get_clean();
  } ?>

2) Now, instead of echoing the output directly, as I said save it in an array:

Explanation: Everytime the MyLoopCode() function is called, it output is now stored in the array $myarray. So, NO output is sent to the browser yet.

<?php query_posts('posts_per_page=1&author=2'); if (have_posts()) : while (have_posts()) : the_post(); ?>

  <?php $myarray[] = MyLoopCode(); ?>

<?php endwhile; endif; ?>

After all these function calls, the content of $myarray will look like (pseudo-code):

myarray[0] = user1-post1 + user1-post2 + user1-post3 + user1-post4 + user1-post5;  
myarray[1] = user2-post1 + user2-post2 + user2-post3 + user2-post4 + user2-post5;  
myarray[2] = user3-post1 + user3-post2 + user3-post3 + user3-post4 + user3-post5;  
myarray[3] = user4-post1 + user4-post2 + user4-post3 + user4-post4 + user4-post5;  
myarray[4] = user5-post1 + user5-post2 + user5-post3 + user5-post4 + user5-post5;  

3) Now, randomize the array contents using shuffle() and display them:

Explanation: The shuffle() function randomizes the contents of the $myarray. Since this array contains all the posts by individual user, what really happens is that the posts-user groups are randomized. Finally traverse the array by foreach and echo the contents.

 <?php
  shuffle($myarray);

  foreach($myarray as $x)
        echo $x;
 ?>
