Displaying blog with excluded categories in archive problem WordPress

Chris Bavota answers:

You can add a conditional tag on your archive.php file within the WordPress loop that ignores any post within that category. Or in the loop.php file if your theme is using it. Here is what it would look like in the appropriate place in the TwentyTen loop.php file.

<?php if(!in_category("6")) : ?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>

<div class="entry-meta">
<?php twentyten_posted_on(); ?>
</div><!-- .entry-meta -->

<?php if ( is_archive() || is_search() ) : // Only display excerpts for archives and search. ?>
<div class="entry-summary">
<?php the_excerpt(); ?>
</div><!-- .entry-summary -->
<?php else : ?>
<div class="entry-content">
<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?>
<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'twentyten' ), 'after' => '</div>' ) ); ?>
</div><!-- .entry-content -->
<?php endif; ?>

<div class="entry-utility">
<?php if ( count( get_the_category() ) ) : ?>
<span class="cat-links">
<?php printf( __( '<span class="%1$s">Posted in</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-cat-links', get_the_category_list( ', ' ) ); ?>
</span>
<span class="meta-sep">|</span>
<?php endif; ?>
<?php
$tags_list = get_the_tag_list( '', ', ' );
if ( $tags_list ):
?>
<span class="tag-links">
<?php printf( __( '<span class="%1$s">Tagged</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-tag-links', $tags_list ); ?>
</span>
<span class="meta-sep">|</span>
<?php endif; ?>
<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyten' ), __( '1 Comment', 'twentyten' ), __( '% Comments', 'twentyten' ) ); ?></span>
<?php edit_post_link( __( 'Edit', 'twentyten' ), '<span class="meta-sep">|</span> <span class="edit-link">', '</span>' ); ?>
</div><!-- .entry-utility -->
</div><!-- #post-## -->

<?php comments_template( '', true ); ?>
<?php endif; ?>

Add a filter:


# Exclude categories | functions.php
function fd_remove_cat( $notused )
{
global $wp_query;
$wp_query->query_vars['cat'] = '-3';
}
add_action('pre_get_posts', 'fd_remove_cat' );
