Number of columns in Category page

Hi there,

you can use the generate_blog_get_column_count filter:

https://docs.generatepress.com/article/using-columns-in-the-blog/#changing-the-number-of-columns

your code would be something like;

add_filter( 'generate_blog_get_column_count','tu_search_column_count' );
function tu_search_column_count( $count ) {
    if ( is_category('the_category_term_slug') ) {
        return 33;
    }

    return $count;
}

Just amend the the_category_term-slug to match.

This article explains adding PHP.

Hi, thanks for reply.

Using Code Snippets plugin I created a new snippet and inserted this:

add_filter( 'generate_blog_get_column_count','tu_search_column_count' );
function tu_search_column_count( $count ) {
    if ( is_category('corsi-e-lab-2021') ) {
        return 33;
    }

    return $count;
}

where corsi-e-lab-2021 is the category slug but it is still on one column.

Can you also add this as well?

add_filter( 'generate_blog_columns','tu_portfolio_columns' );
function tu_portfolio_columns( $columns ) {
    if ( is_category('corsi-e-lab-2021') ) {
        return true;
    }

    return $columns;
}

Perfect, thanks a lot.

No problem :)

Sorry, if I try to do the same for another category (https://www.poesiapresente.it/argomenti/corsi-e-lab-conclusi/) cloning the two snippets and changing the slug, I get this warning:

The snippet has been deactivated due to an error on line 3:

Cannot redeclare function tu_portfolio_columns.

for this snippet:

add_filter( 'generate_blog_columns','tu_portfolio_columns' );
function tu_portfolio_columns( $columns ) {
    if ( is_category('corsi-e-lab-conclusi') ) {
        return true;
    }

    return $columns;
}

the other one is ok.

Hi Antonio,

You don't have to add in a new snippet.

You only need to change the if() condition of the existing one.

Example, if you want to include more categories, change line if ( is_category('corsi-e-lab-2021') ) to:

if ( is_category(array('corsi-e-lab-2021','corsi-e-lab-conclusi')) )

And if you want to add more, just include it inside the array()

example:

if ( is_category(array('corsi-e-lab-2021','corsi-e-lab-conclusi','another-category-slug','one-more-category-slug')) )

Thanks a lot.

No problem. :D
