How to find the number of Tags a post has?

Question

Is is possible to find how how many tags (and categories) a post has and to display it?

something like this: when a post has three Tags and two categories, at the end of the post show that number inside brackets, like so:

TAGS (3) | CATEGORIES (2)

I would like to have it so, because i would like that the tag/category list is hidden until the user clicks or hovers it.

Right now i am making the Tags into an unordered list like this:

the_tags('<ul><li>','</li><li>','</li></ul>');

thanks!

Answer 1

for tags you can use

$tags = get_tags();
$categories = get_categories();

$no_of_tags = count($tags);
$no_of_categories = count($categories);

refer this if you need more details : http://codex.wordpress.org/Function_Reference/get_tags http://codex.wordpress.org/Function_Reference/get_categories

Answer 2

Use this,

$tags = wp_get_post_terms($post_id, 'post_tag');
        echo 'TAGS ('.count($tags).')';

$category = wp_get_post_terms($post_id, 'category');
        echo 'Category ('.count($category).')';

Use this code on your post loop: ya display on single.php

<?php
    while ( have_posts() ) : the_post();
        $tags = wp_get_post_terms($post->ID);
         echo 'TAGS ('.count($tags).')';
         $categories = get_categories();
         echo 'CATEGORIES ('.count($categories).')';
    endwhile;
?>

Taking a little bit from all of you, this is what i ended up using:

$tags = wp_get_post_terms($post->ID);
echo 'TAGS ('.count($tags).')'

$categories = wp_get_post_terms($post->ID, "category");
echo 'CATEGORIES ('.count($categories).')'

Thank you all for your quick help! =)
