function excludecatfeed($query) {

if(is_feed()) {

$query->set('cat','-1');

return $query;

}

}
 add_filter('pre_get_posts', 'excludecatfeed');

Just indicate the ID number of the category you want excluded. In the above code, the ID number is “1”. Just replace the value if needed and just leave the minus “-“ symbol as is. To exclude more categories, just append the ID number separated by a comma (see example below).

$query->set('cat','-1, -5, -7');

Hope some of you find this nice little trick useful. Have a good day, everyone!

With his method, you’ll be tinkering a bit with the index.php file. The whole idea is to create some space right after the first post listing and display a random archive post as the second one. The steps involve is as follows:

• Find the loop.
• Include “$first_post_marker = true;” just above the loop.
• Locate the closing “endwhile;” of the loop.
• Include the following code directly above this “endwhile;”:

if($first_post_marker && strlen($_SERVER['REQUEST_URI']) < 2)    //to make sure that we’re on the first page

{

if(is_home())

{

$week = date(‘W’);

$whatyear = date(‘Y’)-1;

$custom_query = new WP_Query( ‘year=’ . $whatyear . ‘&w=’ . $week . ‘&orderby=rand’);    //random entry from the archive; same week, only one year back

while($custom_query->have_posts())

{

$custom_query->the_post();

/* ==================================

Here’s where you display your post, use the same formatting you’re using in the main loop.

Usually calls like: “the_title();” and “the_content(”);” and so on.

================================== */

break;    //we only need one post

}

wp_reset_postdata();

}

$first_post_marker = false;
 }
