Display Author, Date, and Category ∞

This custom code will give your teasers a byline in this format:

by (author) on (date) in (category)

First, uncheck the author name, date, and primary category elements under Design Options > Teasers > Teaser Display Options to avoid duplication.

Then, place this code in custom_functions.php:

function my_teaser_byline() {
	global $thesis_design;
	$date_formats = thesis_get_date_formats();
	$use_format = ($thesis_design->teasers['date']['format'] == 'custom') ? $thesis_design->teasers['date']['custom'] : $date_formats[$thesis_design->teasers['date']['format']];
	echo '<span class="teaser_author">';
	thesis_author();
	echo '</span>';
	echo "\n";
	echo '<abbr class="teaser_date published" title="' . get_the_time('Y-m-d') . '">on ' . get_the_time($use_format) . '</abbr>' . "\n";
	$categories = get_the_category();
	echo '<a class="teaser_category" href="' . get_category_link($categories[0]->cat_ID) . '">in ' . $categories[0]->cat_name . '</a>' . "\n";
}

add_action('thesis_hook_after_teaser_headline', 'my_teaser_byline');

Display Date, Edit Link, and Category (on Separate Lines) ∞

This version pulls together the date, edit link, and category, then adds paragraph tags to the category function to put it on a line by itself.

First, uncheck the date, edit post link, and primary category elements under Design Options > Teasers > Teaser Display Options to avoid duplication.

Then, place this code in custom_functions.php:

function my_teaser_byline() {
	global $thesis_design;
	$date_formats = thesis_get_date_formats();
	$use_format = ($thesis_design->teasers['date']['format'] == 'custom') ? $thesis_design->teasers['date']['custom'] : $date_formats[$thesis_design->teasers['date']['format']];
	echo '<abbr class="teaser_date published" title="' . get_the_time('Y-m-d') . '">' . get_the_time($use_format) . '</abbr>' . "\n";
	edit_post_link(__('edit', 'thesis'), '<span class="edit_post">[', ']</span>');
	echo "\n";
	$categories = get_the_category();
	echo '<p><a class="teaser_category" href="' . get_category_link($categories[0]->cat_ID) . '">' . $categories[0]->cat_name . '</a></p>' . "\n";
}

add_action('thesis_hook_after_teaser_headline', 'my_teaser_byline');

Place this code in custom.css, and change to suit your requirements:

/* Unlinked author name */
.custom span.author {
   color: #888888;
}

/* Linked author name */
.custom span.author a {
   color: #888888;
}

Style Published On Date ∞

Place this code in custom.css, and change to suit your requirements:

.custom abbr.published {
   font-weight:bold;
   cursor: default;
}

Style Comments and Categories Links ∞

Place this code in custom.css, and change to suit your requirements:

.custom .headline_meta a {
   color: #888888;
}

Note that this style will also be applied to the linked author names, unless you’re also using the code in Style Author Name, above.

Remove Italics and Uppercase Formatting ∞

Place this code in custom.css:

/* Remove Italics */
.custom .headline_meta {
   font-style: normal;
}
/* Remove Uppercase */
.custom .headline_meta span,
 .custom .headline_meta abbr {
   text-transform: none;
}

In some cases, you may need to use custom functions to achieve the results you want. Here are some examples of how to make changes to the byline, using both the standard options and custom functions.

Hide Number of Comments ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show number of comments in byline” option.

Hide Post Categories ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show post categories” option.

Move Post Categories to First Line ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show post categories” option. Then, place this code in custom_functions.php:

function add_to_byline() {
  if (!is_page())
    echo ' in <span>' . get_the_category_list(',') . '</span>';
}

add_action('thesis_hook_byline_item', 'add_to_byline', '99');

Move Entire Byline to After Post ∞

In the Design Options panel, under Display Options : Bylines, uncheck all options. Then, place this code in custom_functions.php:

function custom_byline() { ?>

<p class="headline_meta"><?php thesis_author(); ?> on <abbr class="published" title="<?php echo get_the_time('Y-m-d'); ?>"><?php echo get_the_time(get_option('date_format')); ?></abbr>
 &middot; <span><a href="<?php the_permalink(); ?>#comments" rel="nofollow">
 <?php comments_number(__('0 comments', 'thesis'), __('1 comment', 'thesis'), __('% comments', 'thesis')); ?></a></span></p>

<p class="headline_meta"><?php the_tags('tagged as <span>', ', ', '</span>'); ?>
 in <span><?php echo get_the_category_list(','); ?></span></p>

<?php }

add_action('thesis_hook_after_post', 'custom_byline');

Add “Posted In” Before Category ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show post categories” option. Then, place this code in custom_functions.php:

function add_to_byline() { ?>
    </p><p class="headline_meta"><?php echo __('Posted in:', 'thesis') . ' <span>' . get_the_category_list(',') . '</span>'; ?>
<?php }
add_action('thesis_hook_byline_item', 'add_to_byline', '99');

Add Time Stamp After Published On Date ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show published-on date in post byline” and “Show number of comments in byline” options. Then, place this code in custom_functions.php:

function custom_byline() {
  if (!is_page()) { ?>
  <p class="headline_meta"><abbr class="published" title="<?php echo get_the_time('Y-m-d H:i'); ?>"><?php echo get_the_time(get_option('date_format')); ?> <?php the_time('G:i a'); ?></abbr>
 &middot; <span><a href="<?php the_permalink(); ?>#comments" rel="nofollow">
 <?php comments_number(__('0 comments', 'thesis'), __('1 comment', 'thesis'), __('% comments', 'thesis')); ?></a></span></p>
<?php }
}

add_action('thesis_hook_after_headline', 'custom_byline');

Note: This code excludes Pages from having the custom byline applied; you will need to remove the extra conditional code if you wish to use it on Pages as well.

Move Date to Before Title ∞

In the Design Options panel, under Display Options : Bylines, uncheck the “Show published-on date in post byline” and “Show published-on date in page byline” options. Then, place this code in custom_functions.php:

function add_to_byline() { ?>
   <p class="headline_meta"><?php echo (''). ' <span>' .get_the_time('F j, Y') . '</span></p>'; ?>
<?php }

add_action('thesis_hook_before_headline', 'add_to_byline', '1');

Display an Avatar Next to Byline ∞

Place this code in custom_functions.php (replacing http://www.example.com/path/to/your/images/avatar.gif with the URL to your avatar):

/* byline avatar */
function byline_avatar() {
echo '<img class="byline_avatar" src="http://www.example.com/path/to/your/images/avatar.gif" />';
}

add_action('thesis_hook_before_headline', 'byline_avatar');

Then, place this code in custom.css (adjust margin value as desired):

/*avatar styles*/
.custom .byline_avatar {
   float: left;
   margin-right: 0.5em;
   margin-bottom: 0.5em;
}

Avatars for Multiple Authors ∞

Place this code in custom_functions.php (replace 50 with the desired pixel size):

/* byline avatars */
function byline_avatars() {
  echo get_avatar(get_the_author_id(), 50);
}

add_action('thesis_hook_before_headline', 'byline_avatars');

Then, place this code in custom.css (adjust margin value as desired):

/*avatar styles*/
.custom .avatar {
   float: left;
   margin-right: 0.5em;
   margin-bottom: 0.5em;
}

Hide Byline on Archives & Category Pages Only ∞

Place this code in custom_functions.php:

function custom_body_class($classes) {
 if (is_archive() || is_category()) {
    $classes[] .= 'hide_meta';
 }
    return $classes;
}
add_filter('thesis_body_classes', 'custom_body_class');

Then, place this code in custom.css:

/* hide meta */
.custom.hide-meta .headline_meta {display:none;}
