Last updated in footer entry-meta

We should be able to code that up :)

Do you want it to display in the post excerpt, the single post or both?

Lets go with both.

So the best way to do this right now is to append it to the tags:

add_filter( 'generate_tag_list_output', 'tu_add_updated_date_to_footer_meta' );
function tu_add_updated_date_to_footer_meta( $output ) {
    $time_string = false;

    if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
        $time_string = '<time class="updated" datetime="%1$s" itemprop="dateModified">%2$s</time>';
    }

    if ( $time_string ) {
        $time_string = sprintf( $time_string,
            esc_attr( get_the_modified_date( 'c' ) ),
            esc_html( get_the_modified_date() )
        );

        $time_string = '<span class="updated-footer-date">' . $time_string . '</span>';
    }

    return $output . $time_string;
}

Let me know if this does it or not :)

It displays the date below the tag meta as July 7, 2018. How do I add the Last Updated text?
I you need to look I updated the first post with the URL.

Did more testing and the date only shows if a post has a tag defined.

Ok, I think I got it with the help of some old code. Could you please review the code, it does work.

Hey! Tom’s wife is in labor, he will get to this topic as soon as he can 🙂

That works, but using a filter is preferred. However, it is required that tags or categories are active in order to add the filter (for now).

The solution you found will work until we add a hook into the meta area :)

Thank you.

No problem :)

Hey back on the filter idea, could we use the generate_category_list_output and display before the cats are displayed?

Took your advice and went the filter route.

add_filter( 'generate_category_list_output', 'dw_add_updated_date_to_footer_meta' );
function dw_add_updated_date_to_footer_meta( $output ) {
    $time_string = false;

    if ( ! is_front_page() && ! is_home() ) {

        if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
            $time_string = '<time class="updated" datetime="%1$s" itemprop="dateModified">%2$s %3$s</time>';
        }

        if ( $time_string ) {
            $time_string = sprintf( $time_string,
                esc_attr( get_the_modified_date( 'c' ) ),
                __( 'Last Updated:','generatepress'),
                esc_html( get_the_modified_date() )
            );

            $time_string = '<span class="updated-on">' . $time_string . '</span>';
        }
    }
    return $time_string . $output;
}

Works fine.

Awesome! Glad you got it working :)
