Custom taxonomy terms in widget

Hi Helen!

I won’t be online for a couple of hours, but I promise I’ll get back to you as soon as I can.

You were so close, Helen ??

The problem in your code is that you’re using the_terms, which outputs a string when called. What you need is get_the_terms, which returns the value so you can use it later somewhere else in your code.

I made some changes to your code. Try this:

/// get custom taxonomy using the post ID outside the loop.
function get_year_by_id($post_id){
	$out = array();
	$taxonomy_slug = 'god';
	$terms = get_the_terms( $post_id, $taxonomy_slug );

	if ( !empty( $terms ) ) {
		foreach ( $terms as $term ) {
			$out[] =
				'  <a href="'
				.    get_term_link( $term->slug, $taxonomy_slug ) .'">'
				.    $term->name
				. "</a>";
		}
	}

	return implode( '', $out );
} 

/// add 'year' to WPP widget
function my_custom_popular_posts_html_list( $mostpopular, $instance ){
	$output = '<ul class="wpp-list">';

	// loop the array of popular posts objects
	foreach( $mostpopular as $popular ) {
		$post_tax = get_year_by_id( $popular->id );
		$output .= "<li><a href=\"" . get_the_permalink( $popular->id ) . "\" title=\"" . esc_attr( $popular->title ) . "\"><br>{$popular->title}</a> <span class=\"wpp-stats\">{$popular->pageviews}</span>" . $post_tax . "</li>" . "\n";
	}
	$output .= '</ul>';

	return $output;
}

add_filter( 'wpp_custom_html', 'my_custom_popular_posts_html_list', 10, 2 );

Oh My God! I knew I should have learned php before getting into whole “let’s make a bunch of kinda easy upgrades on our site” =))

Thank you very much for your time and kindness!!! The code works perfectly!

One more little question (though, you know, the hardest ones are always hiding behind that statement =)):
now there is a {$popular->pageviews} where are {$popular->stats} was before, so I couldn’t get pageviews and comments in 2 different widgets if I use filter from the above?

That’s OK, we all have to start somewhere to learn stuff ?? All credits to you for your effort!

If I remember correctly, to display the comments count you need to add {$popular->comment_count}.

To make this exercise even better, let’s say that you also want the ability to decide whether to display comments / views or not. You want one widget displaying both views and comment count, and another one just the views count. Take a look at the code now:

/// get custom taxonomy using the post ID outside the loop.
function get_year_by_id($post_id){
	$out = array();
	$taxonomy_slug = 'god';
	$terms = get_the_terms( $post_id, $taxonomy_slug );

	if ( !empty( $terms ) ) {
		foreach ( $terms as $term ) {
			$out[] =
				'  <a href="'
				.    get_term_link( $term->slug, $taxonomy_slug ) .'">'
				.    $term->name
				. "</a>";
		}
	}

	return implode( '', $out );
} 

/// add 'year' to WPP widget
function my_custom_popular_posts_html_list( $mostpopular, $instance ){
	$output = '<ul class="wpp-list">';

	// loop the array of popular posts objects
	foreach( $mostpopular as $popular ) {
		$stats = ''; // placeholder for the stats tag

		// either the Pageviews or Comments count is activated on the widget, so let's add the stats HTML tag
		if ( $instance['stats_tag']['comment_count'] || $instance['stats_tag']['views'] ) {
			$stats = "<span class=\"wpp-stats\">";

			// Comment count option active, display comments
			if ( $instance['stats_tag']['comment_count'] ) {
				// display text in singular or plural, according to comments count
				$stats .= sprintf(
				_n('1 comment', '%s comments', $popular->comment_count, 'wordpress-popular-posts'),
				number_format_i18n($popular->comment_count)
				);
			}

			// Pageviews option active, display views
			if ( $instance['stats_tag']['views'] ) {

				// if comments count is also active, let's add a separator (character)
				if ( $instance['stats_tag']['comment_count'] ) {
					$stats .= " | ";
				}

				// If sorting posts by average views
				if ($instance['order_by'] == 'avg') {
					// display text in singular or plural, according to views count
					$stats .= sprintf(
					_n('1 view per day', '%s views per day', intval($popular->pageviews), 'wordpress-popular-posts'),
					number_format_i18n($popular->pageviews, 2)
					);
				} else { // Sorting posts by views
					// display text in singular or plural, according to views count
					$stats .= sprintf(
					_n('1 view', '%s views', intval($popular->pageviews), 'wordpress-popular-posts'),
					number_format_i18n($popular->pageviews)
					);
				}
			}

			$stats .= "</span>";
		}

		$post_tax = get_year_by_id( $popular->id );
		$output .= "<li><a href=\"" . get_the_permalink( $popular->id ) . "\" title=\"" . esc_attr( $popular->title ) . "\"><br>{$popular->title}</a> {$stats}" . $post_tax . "</li>" . "\n";
	}
	$output .= '</ul>';

	return $output;
}

add_filter( 'wpp_custom_html', 'my_custom_popular_posts_html_list', 10, 2 );

The $instance variable in function my_custom_popular_posts_html_list( $mostpopular, $instance ) contains the configuration info from the widget. This way, you can have your custom HTML and have each widget behave differently according to its settings.

Amusing, huh? ??

Hello Hector and Helen. Thanks for this info. I was looking for a way to replace the Category displayed in WPP with a custom taxonomy and this seems like it would do the trick. But can someone guide me on how to execute this? I’ve added the code to the functions.php, but how do I edit the widget to actually call the taxonomy name into the display?

Hi jlibrizzi!

The taxonomy is hard-coded, actually: $taxonomy_slug = 'god';, where ‘god’ is the taxonomy slug Helen is using. You need to change it to your custom tax (eg. $taxonomy_slug = 'movies';).

Thanks so much for the quick reply! Unfortunately I’m being a little dense. I changed the slug to match mine. But then do I need to do anything to make it actually appear on the front end? For example, I’ve got this post HTML markup:

<li>
<h4 class="cat-title">{category}</h4>
<h2 class="entry-title">{title}</h2>
</li>

Do I need to replace {category} with {movies} (or whatever the taxonomy slug is?

In your case, the code should be something like this:

/// get custom taxonomy using the post ID outside the loop.
function get_year_by_id($post_id){
	$out = array();
	$taxonomy_slug = 'god'; // <--- YOUR TAXONOMY SLUG GOES HERE

	$terms = get_the_terms( $post_id, $taxonomy_slug );

	if ( !empty( $terms ) ) {
		foreach ( $terms as $term ) {
			$out[] =
				'  <a href="'
				.    get_term_link( $term->slug, $taxonomy_slug ) .'">'
				.    $term->name
				. "</a>";
		}
	}

	return implode( '', $out );
} 

/// add 'year' to WPP widget
function my_custom_popular_posts_html_list( $mostpopular, $instance ){
	$output = '<ul class="wpp-list">';

	// loop the array of popular posts objects
	foreach( $mostpopular as $popular ) {
		$stats = ''; // placeholder for the stats tag

		// either the Pageviews or Comments count is activated on the widget, so let's add the stats HTML tag
		if ( $instance['stats_tag']['comment_count'] || $instance['stats_tag']['views'] ) {
			$stats = "<span class=\"wpp-stats\">";

			// Comment count option active, display comments
			if ( $instance['stats_tag']['comment_count'] ) {
				// display text in singular or plural, according to comments count
				$stats .= sprintf(
				_n('1 comment', '%s comments', $popular->comment_count, 'wordpress-popular-posts'),
				number_format_i18n($popular->comment_count)
				);
			}

			// Pageviews option active, display views
			if ( $instance['stats_tag']['views'] ) {

				// if comments count is also active, let's add a separator (character)
				if ( $instance['stats_tag']['comment_count'] ) {
					$stats .= " | ";
				}

				// If sorting posts by average views
				if ($instance['order_by'] == 'avg') {
					// display text in singular or plural, according to views count
					$stats .= sprintf(
					_n('1 view per day', '%s views per day', intval($popular->pageviews), 'wordpress-popular-posts'),
					number_format_i18n($popular->pageviews, 2)
					);
				} else { // Sorting posts by views
					// display text in singular or plural, according to views count
					$stats .= sprintf(
					_n('1 view', '%s views', intval($popular->pageviews), 'wordpress-popular-posts'),
					number_format_i18n($popular->pageviews)
					);
				}
			}

			$stats .= "</span>";
		}

		$post_tax = get_year_by_id( $popular->id );

        $output .= "<li>";
		$output .= "<h4 class=\"cat-title\">{$post_tax}</h4>";
		$output .= "<h2 class=\"entry-title\"><a href=\"" . get_the_permalink( $popular->id ) . "\" title=\"" . esc_attr( $popular->title ) . "\">{$popular->title}</a></h2>";
		$output .= "</li>" . "\n";

	}
	$output .= '</ul>';

	return $output;
}

add_filter( 'wpp_custom_html', 'my_custom_popular_posts_html_list', 10, 2 );

Amusing, huh? ??

Ooohhh… I would call it mind-blowing =))
Who needs magic when there is such power in the code?.. Héctor, you’re like Gandalf – whooosh, and everything’s not only working but actually making sense =)

where ‘god’ is the taxonomy slug

ahah, I’ve just realized how strange it’s looking =)) ‘god’ means ‘year’ in Russian =) I’m not running a site with classification for Gods =))

Hey, jlibrizzi! Welcome to the party! =) I’m glad that this thread is useful for you, but since I’ve got my answer, I’m marking it ‘resolved’.

Héctor, thank you for your time and patience!! =) I’m having some issue with posts sorting, but I’ll start a new topic for that ??
