Filtering Children of the “uncategorized” Category out of the Loop?

Hi @Scott B: UPDATE FROM PRIOR ANSWER: Due you my evidently poor reading comprehension skills(!) where I missed the requirement to filter out children (Thanks @Adam BlackStrom for calling attention to my oversight) I’ve modified the code provided. I think you want to use the list_terms_exclusions filter hook. Add this to your plugin (or others … Read more

Wrap a chosen category name with div

get_term_by returns an object by default, so you could output the term name using <?php $term = get_term_by(‘name’, ‘foo’, ‘category’); echo “<div>$term->name</div>”; ?>

Show posts of one category only with Custom Taxonomy on single.php

Since I’m not sure if you are using single.php for anything else, I am going to suggest that you copy single.php to single-14kgs.php in the theme directory.

get_page_by_path does something similar: function pagefromcat_template_redirect() { if ( ! is_category() ) { return; } $category = get_queried_object(); $page = get_page_by_path( $category->slug ); if ( $page instanceof WP_Post ) { $url = get_permalink( $page ); wp_safe_redirect( $url, 301 ); } } add_action( ‘template_redirect’, ‘pagefromcat_template_redirect’ );

is_category in pre_get_posts results in php notices

is_category(‘category-name’) won’t work until after the query is run. If we check source code where those notices are generated, we can see that it’s using get_queried_object, which gets populated with the results of the main query, and at the pre_get_posts stage will still be empty. As an alternate, check the contents of $query->query_vars, which will … Read more
