[Resolved] Set excerpt only for categories

[Diego Fernando]

Hello Tom

Please, two questions

How can I set the excerpt but only for the categories. On the home page, if is possible, I just want excerpt only for the first post that has full width. The rest of the post, I don’t want to have excerpt.

The second question is:
On home page (blog page), when I place the empty excerpt field, I get 3 dots (…) below the featured image. How can I delete them? I was viewing related post, but were about to delete dots with masonry style. I have columns.

Thank you for your help. I love GP

Tough question! You would use the excerpt_length filter.

For example, this will set the excerpt length of the first post on a page, then the rest won’t have an excerpt:

add_filter( 'excerpt_length','tu_custom_excerpt_length', 1000 );
function tu_custom_excerpt_length( $length ) {
    global $wp_query; // assuming you are using the main query
    if ( 0 === $wp_query->current_post) {
        return $length;
    } else {
        return 0;
    }
}

You can add more conditionals in there for is_category() etc..

Then you can do the same thing for the more link:

add_filter( 'excerpt_more', 'tu_custom_more_tag', 100 );
function tu_custom_more_tag( $more ) {
    global $wp_query; // assuming you are using the main query
    if ( 0 === $wp_query->current_post) {
        return $more;
    } else {
        return '';
    }
}

Hope that’s enough to get you going 🙂

Hello Tom

Maybe, there is a mistake in my procediment

I put the code in Simple PHP. I got an excerpt in the the first post of home and categories page, and the rest of the post don’t have excerpt. It is wonderfur for the home page.

But I was wondering, how I can set normal excerpt in categories? I want all posts with excerpt.

Tom, thank you for the support

This should do it:

add_filter( 'excerpt_length','tu_custom_excerpt_length', 1000 );
function tu_custom_excerpt_length( $length ) 
{
    // Return the normal length if we're not on the front page
    if ( ! is_front_page() )
        return $length;

    global $wp_query; // assuming you are using the main query
    if ( 0 === $wp_query->current_post) {
        return $length;
    } else {
        return 0;
    }
}

add_filter( 'excerpt_more', 'tu_custom_more_tag', 100 );
function tu_custom_more_tag( $more ) 
{
    // Return the normal more link if we're not on the front page
    if ( ! is_front_page() )
        return $more;

    global $wp_query; // assuming you are using the main query
    if ( 0 === $wp_query->current_post) {
        return $more;
    } else {
        return '';
    }
}
