List post tags in sidebar

Hi,

I want something similar to this. I want the all tags available in the post on my archive.php to be shown in the sidebar. How can I do this?

Here’s just one example. In your sidebar.php define the post id as a global variable and call a custom function from functions.php

sidebar.php

// define globals
global $constant_post_id;
$constant_post_id = $post->ID;

// get post tags
get_content(sidebar_post_tags);

functions.php

function get_content($element) {
	do_action($element);
};
function get_sidebar_post_tags() {
	global $constant_post_id;
	$content .= "<h2>Tags<h2><ul>";
	$tags = wp_get_object_terms($constant_post_id, 'post_tag');
	foreach ($tags as $tag) {
		$content .= "<li><a href=\"".get_tag_link($tag->term_id)."\">$tag->name</a></li>";
	};
	$content .= "</ul>";
	echo $content;
}
add_action('sidebar_post_tags','get_sidebar_post_tags');

Thanks for the code, I made a few edits so I could use it to pull in the post tags for meta keywords. I had 2 questions, is there a better way to do this? and how can I get rid of the last comma?

Here is the code…

function get_content($element) {
	do_action($element);
};
function get_post_tags() {
	global $constant_post_id;
	$tags = wp_get_object_terms($constant_post_id, 'post_tag');
	foreach ($tags as $tag) {
		$content .= $tag->name . ",";
	};
	echo $content;
}
add_action('post_tags','get_post_tags');

Answer to your first question. Insert this before echo $content.

$content = rtrim($content,',');

As for your second question. I’m sure there is 1000 different ways to do the same thing. If this works for you, then go with it.

thanks for the help.
