Exclude Single Post in WordPress
If you would like to exclude one post from your blog, archive, search results or wherever you need to on your blog, you can do so by putting in a small piece of code within the particular WordPress loop:
The following example will show all posts except for the post with the ID of 179:
<?php if ( $post->ID == '179' ) continue;?>
This is something that I get a lot of requests for and is very useful in a number of situations.
