Why does apply_filters behave different inside and outside a loop?
There is a difference because you are not using the_post function in the first example. What this function does is it calls setup_postdata function, which sets up all the globals needed for other functions to work.

You can get the selected page for posts by the following code: $page_for_posts = get_option( ‘page_for_posts’ ); Then, get the requested post by: $post = get_post( $page_for_posts ); And, get the data you need: echo apply_filters( ‘the_title’, $post->post_title ); echo apply_filters( ‘the_content’, $post->post_content ); echo get_post_meta( $post->ID, $key, $single);
Performance concerns: index.php vs taxonomy-$taxonomy.php
TL;DR Template: Performance not so much, semantics however, use hierarchy! TL;DR Query String: Use provided hooks, never edit directly. The Template File Apart from performance, first look at semantics. If you direct your browser to a taxonomy archive, WordPress will look for the following files (straight from the Codex): taxonomy-{taxonomy}-{term}.php – If the taxonomy were … Read more
Does search.php autofilter The Loop?
The loop doesn not display the latest posts, it just shows the posts the main query has found.
