Modifying category pages possibility

Hi there,

As for #1:
I'm not sure I understand what you mean.

Are you trying to dynamically change the breadcrumb title value by taking something from a custom field?

If that's the case, it really depends on the breadcrumbs code you're using. If you're using a plugin for your breadcrumbs, you should ask the plugin's developer/support on best practices on how to do it.

As for #2:

You need to change the post per page for them.

Try this PHP snippet:

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_category('your-category-slug') ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

Change your-category-slug to the category slug you want to increase the post displayed and change the 9 to the number of posts you want to appear.

If you want to apply it on multiple categories, you can modify the code into something like this:

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_category( array('your-category-slug-1','your-category-slug-2','your-category-slug-3') ) ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

Or if you want it to apply to ALL category archives, simply leave the is_category( ) empty.

Example:

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_category() ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

As for #3:

You'll need a plugin that does this exact feature. This isn't a default GP feature, unfortunately.

Thanks for that! For #1 it's basically I don't want the post title to appear for the archvies pages of posts - instead, I would rather the displayed title on these pages be something else, such as my own shortcode or the 'Breadcrumb title' that yoast use.

Basically, if an article is 'Still I Rise by Maya Angelou', I want that post to appear as 'Still I Rise' on the category page, because the category page is Maya Angelou (doesn't need repeating again)

Interesting, do you want to keep the "By xx" on the single post?

Not 100% sure it will work, but you could try this:

add_filter( 'the_title', function( $title ) {
    if ( ! is_archive() ) {
        return $title;
    }

    return strpos( $title, "by" ) ? substr( $title, 0, strpos( $title, "by" ) ) : $title;
} );

That works a treat! The only issue is that for some poems 'by' is in the poem title.

Take the post title 'Stopping by Woods on a Snowy Evening by Robert Frost'. The above code causes the post title to appear as the below:

Is there a way so that it only removed the last 'by ____' instead of what appears above (so the poem always appears)?

Hi there,

Let's try modifying Tom's code a bit.

Try this:

add_filter( 'the_title', function( $title ) {
    if ( ! is_archive() ) {
        return $title;
    }

    return strrpos( $title, "by" ) ? substr( $title, 0, strrpos( $title, "by" ) ) : $title;
} );

Ah that's amazing thank you!

Is it possible to only show these for categories archives and no other categories?

Not sure if this works as you want but try this out.

add_filter( 'the_title', function( $title ) {
    if ( ! is_archive() ) {
        return $title;
    }

    if ( is_category() ) {     
        return strrpos( $title, "by" ) ? substr( $title, 0, strrpos( $title, "by" ) ) : $title;
    }

} );

That's great thank you!

No problem. Glad to be of any help. :D

Hi there,

Thanks for this code, but it appears on author archives the posts disappear completely when the above code is implemented. Is there a way for the code to be modified so the post title is kept in tact for author pages?

Kind regards,

What happens if you try this?

add_filter( 'the_title', function( $title ) {

    if ( is_category() ) {     
        $title = strrpos( $title, "by" ) ? substr( $title, 0, strrpos( $title, "by" ) ) : $title;
    }

    return $title;

} );

Let us know.

Perfect :) thank you!

Nice one. Glad it works for you. No problem. :D
