Do not duplicate post covering 2 queries

http://codex.wordpress.org/The_Loop#Multiple_Loops_in_Action

for ‘do-not-duplicate’ with several loops and posts, try the ‘array method’ described in the above linked docu described after ‘Note for Multiple Posts in the First Category’;

(the first loop – example):

<?php $do_not_duplicate = array();
  $my_query = new WP_Query('posts_per_page=4');
  while ($my_query->have_posts()) : $my_query->the_post();
  $do_not_duplicate[] = $post->ID; ?>

(the second loop – rough example, make sure to use the right query args):

<?php $args=array(
      'posts_per_page' => 1,
      'post__not_in' => array_merge($do_not_duplicate, get_option( 'sticky_posts' )),
      'category__in' => array($category->term_id)
);
 $my_query = new WP_Query( $args );
  while ($my_query->have_posts()) : $my_query->the_post();
  $do_not_duplicate[] = $post->ID; ?>

(any further loop – rough example, the query args need adjusting):

<?php $args=array(
      'posts_per_page' => 1,
      'post__not_in' => array_merge($do_not_duplicate, get_option( 'sticky_posts' )),
      'category__in' => array($category->term_id)
);
 $my_query = new WP_Query( $args );
  while ($my_query->have_posts()) : $my_query->the_post();
  $do_not_duplicate[] = $post->ID; ?>

i hope this gives you the idea how to use the method.

if you need help with the details, please paste the full code of the template into a http://pastebin.com/ and post the link to it here.

please do the above, so i can see the full code.

in the first loop, try:

<?php $do_not_duplicate = array();
  $my_query = new WP_Query(array('posts_per_page' => 4, 'post__not_in' => get_option( 'sticky_posts' ) ) );
  while ($my_query->have_posts()) : $my_query->the_post();
  $do_not_duplicate[] = $post->ID; ?>

hope you can check what i’ve changed in the code;

hopefully it will work with your posts 😉

on the third loop, the latest post from each category doesn’t come from the good category.

are the posts in more than one category?

in the third loop, try to change:

foreach($categories as $category) {
    $args=array(
      'posts_per_page' => 1,

to:

foreach($categories as $category) {
    $args=array(
      'numberposts' => 1,

and please paste the full code of the third loop into a http://pastebin.com/ and post the link to it here.

please paste the real section that you are actually using in your template.
not the one with HTML CODE HERE

in you pasted version, you are missing the ‘category__in’ parameter for the ‘get_posts()’ loops.

$args=array(
     'numberposts' => 1,
        'post__not_in' => array_merge($do_not_duplicate,get_option( 'sticky_posts' )),
    );

the category paramter in the $args is missing;

try:

$args=array(
     'numberposts' => 1,
        'post__not_in' => array_merge($do_not_duplicate,get_option( 'sticky_posts' )),
'cetagory__in' => array($category->term_id)
    );
