[Resolved] Created date on first publish, updated date on update after

Hi Tom,

Concerning the date, it seem to work, I do see the last updated date for the posts.

What should I do in order to prefix the date with the text “Published on” vs “Updated on” depending on if it is the first time publish vs an update?

I created a new post and I see “Updated on ” + date, not “Created on ” + date. (In French, “Publié le ” + “Mis à jour le “)

Here is all I have done trying to make it work.

I created the following code snippet:

add_filter( 'wpsp_date_output', 'tu_wpsp_updated_date_first' );
function tu_wpsp_updated_date_first() {
	$time_string = '';
	
	if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
		$time_string .= '<time class="wp-show-posts-updated" datetime="%3$s" itemprop="dateModified">%4$s</time>';
	}
	
	$time_string .= '<time class="wp-show-posts-entry-date published" datetime="%1$s" itemprop="datePublished">%2$s</time>';
	
	$time_string = sprintf( $time_string,
		esc_attr( get_the_date( 'c' ) ),
		esc_html( get_the_date() ),
		esc_attr( get_the_modified_date( 'c' ) ),
		esc_html( get_the_modified_date() )
	);
	
	// If our date is enabled, show it
	$output = sprintf(
		'<span class="wp-show-posts-posted-on wp-show-posts-meta">
			<a href="%1$s" title="%2$s" rel="bookmark">%3$s</a>
		</span>',
		esc_url( get_permalink() ),
		esc_attr( get_the_time() ),
		$time_string
	);

	return $output;
	
}

I added the following custom CSS:

/* Created after updated date */
.wp-show-posts-updated {
    display: inline-block;
}

.wp-show-posts-updated + .wp-show-posts-entry-date {
    display: none;
}

/* Created after updated date label */
.wp-show-posts-entry-date:before {
    content: "Publié le ";
}

.wp-show-posts-updated:before {
    content: "Mis à jour le ";
}

I commented any previous CSS customization attempt.

It was a brand new published post. wirecutter.com use WordPress and they seem able to sort between “published on” vs “updated on”.

I guess I will have to live with “updated on” all of the time instead of “published on” + “updated on” if it require too much work in order to achieve.

I’ve just published this post for the first time 5 minutes ago, i will not update it in the short term.

The problem has not reappeared since the opening of the ticket so I consider it to be a non-recurring intermittent problem that is unlikely to recur easily so we can close this post.
