Your instructions were very clear! I’m also glad it worked out as I wanted. Thanks!

…to be clear, if I use the above code in the function itself it is not showing on the right place. So I need it hard coded in single.php I guess.

I tried the following code on top of the single.php page:

$counts = aigoo_get_score();
			extract( $counts );  //restores compacted variables
			$score = $likescore - $unlikescore;
			$totalvotes = $likescore + $unlikescore;
			if ($score > 0 )
				{
				echo '<span class="plusscore">+'.$score.'</span><br>';
				}
			elseif ($score == 0 )
				{
				echo '<span class="zeroscore">'.$score.'</span><br>';
				}
			elseif ($score < 0 )
				{
				echo '<span class="minusscore">'.$score.'</span><br>';
				}
			if ($totalvotes == 1 )
				{
				echo '<span class="totalvotes">Score uit <a href="#comments">'.$totalvotes.' stem</a></span>';
				}
			elseif ($totalvotes == -1 )
				{
				echo '<span class="totalvotes">Score uit <a href="#comments">'.$totalvotes.' stem</a></span>';
				}
			elseif ($totalvotes == 0 )
				{
				echo '<span class="totalvotes"><a href="#comments">Nu stemmen!</a></span>';
				}
			else
				{
				echo '<span class="totalvotes">Score uit <a href="#comments">'.$totalvotes.' stemmen</a></span>';
				}

And this where the avatars should be on single.php:

echo '<div class="upvoters" id="votes">';
				echo '<span class="numberoflikes">('.count($likes).')</span>';
				echo '<div class="upvoter-img">';
				foreach( $likes as $like )
					echo("<img src=\"".get_avatar_url(get_avatar( $like->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$like->comment_author."\" width=\"40\" height=\"40\">");
				echo '</div>';
				echo '</div>';
				echo '<div class="downvoters">';
				echo '<span class="numberofunlikes">('.count($unlikes).')</span>';
				echo '<div class="downvoter-img">';
				foreach( $unlikes as $unlike )
					echo("<img src=\"".get_avatar_url(get_avatar( $unlike->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$unlike->comment_author."\" width=\"40\" height=\"40\">");
				echo '</div>';
				echo '</div>';

And this in functions.php:

/* Display likes/unlikes */
function aigoo_get_score() {
   $comments = get_comments( array('post_id' => get_the_ID(),) );
			$likes = array();
			$unlikes = array();
			foreach( $comments as $comment ) {
				if('unlike' == $comment->comment_content ) $unlikes[] = $comment;
					else $likes[] = $comment;
			}
    $likescore = count( $likes );
	$unlikescore = count( $unlikes );
	return compact('likescore', 'unlikescore');
}

Now, the code on top of the page is working correctly, but there’re no avatars shown at the bottom of the page.
My idea was to remove the avatars code from the function and put it on the single.php page itself, so then I could call the function on top of the page.

This is the code I use on for example the category page and it looks like it works correctly:

$counts = aigoo_get_score();
					extract( $counts );  //restores compacted variables
					$score = $likescore - $unlikescore;
					$totalvotes = $likescore + $unlikescore;

if ($score > 0 )
					{
					echo '<span>Score +'.$score.'</span>';
					}
					elseif ($score == 0 )
						{
						echo '<span>Score '.$score.'</span>';
						}
					elseif ($score < 0 )
						{
						echo '<span>Score '.$score.'</span>';
						}
					if ($totalvotes == 1 )
						{
						echo '<span> uit '.$totalvotes.' stem</span>';
						}
					elseif ($totalvotes == -1 )
						{
						echo '<span> uit '.$totalvotes.' stem</span>';
						}
					elseif ($totalvotes == 0 )
						{
						echo '<span>Nu stemmen!</span>';
						}
					else
						{
						echo '<span> uit '.$totalvotes.' stemmen</span>';
						}

So, right now I only need the avatars to show. Further, I’m very very happy with this function!

I’m sorry, your code is working *shame on me*.

But only after I call the function with:
$counts = aigoo_get_score();
This code shows the avatars indeed. But the extract code (below) have to work on top of the page, instead of only after the function call. Is that possible? If I call the function on top of the page, also the avatars are shown at the top of the page and that’s what I don’t want.

Also I would like to show the extract code and the $totalvotes code on the category, search and tag pages. Or do I have to call the function otherwise?

So this is the extract code (I style it later, but it works):

extract( $counts );  //restores compacted variables
echo "Number of Likes: $likescore\n";
echo "Number of Unlikes: $unlikescore\n";

And this is the working $totalvotes code:

$totalvotes = $likescore + $unlikescore;
echo ''.$totalvotes.'';

So, my question now is how to show these codes on top of the page and on the category, search and tag pages.

I tried to following code in functions.php:

function aigoo_get_score() {
   $comments = get_comments( array('post_id' => get_the_ID(),) );
			$likes = array();
			$unlikes = array();
			foreach( $comments as $comment ) {
				if('unlike' == $comment->comment_content ) $unlikes[] = $comment;
					else $likes[] = $comment;
			}
	echo '<div class="upvoters" id="votes">';
	echo '<span class="numberoflikes">('.count($likes).')</span>';
	echo '<div class="upvoter-img">';
	foreach( $likes as $like )
		echo("<img src=\"".get_avatar_url(get_avatar( $like->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$like->comment_author."\" width=\"40\" height=\"40\">");
	echo '</div>';
	echo '</div>';
	echo '<div class="downvoters">';
	echo '<span class="numberofunlikes">('.count($unlikes).')</span>';
	echo '<div class="downvoter-img">';
	foreach( $unlikes as $unlike )
		echo("<img src=\"".get_avatar_url(get_avatar( $unlike->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$unlike->comment_author."\" width=\"40\" height=\"40\">");
	echo '</div>';
	echo '</div>';
    $likescore = count( $likes );
	$unlikescore = count( $unlikes );
	return compact('likescore', 'unlikescore');
}

and this code in single.php:

extract( $counts );  //restores compacted variables
echo "Number of Likes: $likescore\n";
echo "Number of Unlikes: $unlikescore\n";

But then I get no scores. Also, under the avatars now is shown the word “array”. Not sure why it isn’t working for me.

I also use this line of code to count the likes and unlikes:
$totalvotes = count($likes) + count($unlikes);
Is there a way I can use this again with the new code?

I’ll try it again, but for now it isn’t working.

Thanks! The message function is working great.

About the other function. This code displays the avatars correctly:

function aigoo_get_score() {
   $comments = get_comments( array('post_id' => get_the_ID(),) );
			$likes = array();
			$unlikes = array();
			foreach( $comments as $comment ) {
				if('unlike' == $comment->comment_content ) $unlikes[] = $comment;
					else $likes[] = $comment;
			}
	echo '<div class="upvoters" id="votes">';
	echo '<span class="numberoflikes">('.count($likes).')</span>';
	echo '<div class="upvoter-img">';
	foreach( $likes as $like )
		echo("<img src=\"".get_avatar_url(get_avatar( $like->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$like->comment_author."\" width=\"40\" height=\"40\">");
	echo '</div>';
	echo '</div>';
	echo '<div class="downvoters">';
	echo '<span class="numberofunlikes">('.count($unlikes).')</span>';
	echo '<div class="downvoter-img">';
	foreach( $unlikes as $unlike )
		echo("<img src=\"".get_avatar_url(get_avatar( $unlike->comment_author_email, 40 ))."\" class=\"tooltip\" title=\"".$unlike->comment_author."\" width=\"40\" height=\"40\">");
	echo '</div>';
	echo '</div>';
   return $score;
}

If I add the following code in the above code…

$likescore=array(count($likes));
$unlikescore=array(count($unlikes));

… and call it with:
echo $likescore;

… then there is no like score displayed.

So the avatars are working great. Only now the working score code isn’t working anymore. I would like to use echo $likescore; and echo $unlikescore; to hold the like and unlike score, because then I can do (I think) the following to calculate the real score:

$score = $likescore - $unlikescore;
$totalvotes = $likescore + $unlikescore;

After that I can style the output with CSS.

So, the avatars are showing, but the score isn’t displaying anymore.

Solved!

I found out. All I had to do was to change $comment->comment_author_email to $like->comment_author_email and $unlike->comment_author_email.
