Exclude post Category from showing up in blogroll

[erh]

Hello,

I finished writing about ten different articles, all grouped together in a single "series".

I prefixed each article with something like "This article is number 3 of 10 in a series on [something]". But when I look at my blogroll, the excerpt of each post is now my "series prefix".

I don't want to write a custom excerpt for each post. I'm perfectly content with WordPress automatically selecting the first 50~ words (or whatever).

I just need to exclude a block of text from being selected as excerpt text.

What is the easiest way to do this without requiring an additional plugin, or requiring me to manually write all the excerpts going forward?

Try pre_get_posts

Brilliant, that did it perfectly. Thanks BradDalton!

Here is the code I used if anyone else comes across this from a search. I added it to my functions.php through this plugin:
https://wordpress.org/plugins/add-actions-and-filters/

function exclude_category( $query ) {
    if ( $query->is_home() && $query->is_main_query() ) {
        $query->set( 'cat', '-17' );
    }
}
add_action( 'pre_get_posts', 'exclude_category' );

(17 was the ID of the category I wanted excluded).

I had same issue. Theme settings not responding. Custom field suggestion found elsewhere not working. This worked! Thanks Brad!
