How to display tags in each blog post with Perch
I saw this post about showing post tags in the post.html template on the Perch forum recently. The post explains how to display tags for a blog post in the post's body rather than, for example, in a sidebar.
At the top of my
post.php page (or in a Perch layout), I create a variable called
tags_html containing my post's tags (using the
perch_blog_post_tags function, described here).
<?php PerchSystem::set_var('tags_html', perch_blog_post_tags(perch_get('s'), , true)); ?>
post.html template, I have this code which displays the tags:
<perch:blog id="tags_html" encode="false" type="hidden" />
It may not be immediately obvious but this uses a modified version of the Perch
post_tag_link.html template to display the tags in an unordered list. The modifications are a class on the
<ul> (so that I can use a tag icon background SVG image on the list items in my CSS) and a cleaner post tag URL. Relatively minor changes.
The hidden value means that this tags field is not shown on the post editing screen (there's already a tags field as part of the default Perch functionality).
That's it. I think it's useful to display tags with the post's content so I'm sure I'll be using this again.
