[Resolved] hidden category page Blog

[alexis]

Hi..,
Sorry I didn’t find an answer to my problem:
I want certain categories (e. g. projects) not to appear on the blog page.
I used this function incorrectly:

add_filter('pre_get_posts', 'excludeCat');
function excludeCat($query) {
      if ( $query->is_blog ) {
            $query->set('cat', 'projets');
      }
      return $query;
}

Which php code to include please ?

Hi there,

Tom provides the code here:

Yes, but it doesn’t work. By which I replace “is_home” as I am the blog page?. And the’3, 5 and 23′ I replaced them with the project categories (name of my category of articles)

You can see the top level conditional tags here:

https://docs.generatepress.com/article/using-hooks-conditional-tags/#blog-posts-page

is_home is the Blog Page not to be confused with the is_front_page which is the home page.

The query must use the ID of the category – not its slug.
Edit the category you wish to exclude and inspect the URL within you will see eg. ID=4

The exclude query will then look like:

$query->set('cat', '-4');

Note the - must remain as this is what removes the category.

Thank you very much! Sorry I was missing some elements but with these explanations I understand. It works well. This is my first site with this theme which is very good for customization

I must say that WP’s naming conventions can scramble the brains a little. Glad to be of help and happy to hear your liking GPP
