I’m trying to create a list of all categories under each article with the categories for that article highlighted. Using EE 2.9. Code is:
{exp:channel:categories channel="news" style="linear"}
<a href="http://{path=%27news/index%27}" class="active">{category_name}</a>
{/exp:channel:categories}Going by the docs this should work. What am i doing wrong?

I suspect you are using the wrong tag. To show what categories a specific entry is assigned to there is a looping {categories}{/categories} pair for the channel:entries tag.
The channel:categories tag is a standalone tag not intended to be nested within a channel:entries tag - if that’s what you are doing.

Hey thanks!
I’m able to show the categories fine in the exp:channel:entries loop using {categories}{/categories} pair. But still nothing in the exp:channel:categories loop (which btw is below the entries loop).
Could this be due to a setting somewhere or how I’ve setup the categories?
A few other points:
I’m using vanilla https://github.com/focuslabllc/ee-master-config for master config; and
System is outside the web root; and
This is my first ee site !

Post your template code.
And you’re getting no results at all?

I’m getting results (all categories which is what I want), but the active tag is not working in exp:channel:categories.
Here’s the code (from Robin- looks like it tripped a spam filter):
{layout="site/.layout"}
{exp:channel:entries channel="news" limit="1"}
{layout:set name="title" value="{title}"}
{layout:set name="meta_desc" value="{exp:eehive_hacksaw cutoff=". " words=""}{news_body}{/exp:eehive_hacksaw}"}
{layout:set name="meta_cont" value="{categories backspace="2"}{category_name}, {/categories}"}
{layout:set name="js" value="<script src='/assets/scripts/libs/galleria.min.js'></script>"}

but the active tag is not working in exp:channel:categories.
Tell me more about what you mean by this…what’s your desired result?
#7 / Aug 24, 2014 8:13pm
What I’m after is a list of all categories, with the categories of the current post styled differently.
#8 / Aug 24, 2014 8:15pm
Let me chew on that one - my gut reaction is “that just isn’t do-able” but sometimes an idea comes later.
The channel:categories tag isn’t URL - aware, so it’s not going to “know” what entry is being displayed. It’s purpose is to show all categories in order so that you can choose one category and see what entries are in that one category.
Likewise the categories looping pair isn’t intended to show all the categories, just the ones the currently-displayed entry has been assigned to.

Sorry about that spam filter- I posted the code for you, raoulw. I don’t actually think you’re running into [this bug](https://support.ellislab.com/bugs/detail/20468/the-if-active-conditional-in-the-channel-categories-tag-may-fail-with-non-u), but since it is related to the active conditional, I’m dropping a ‘heads up’ on it as well.

Let me chew on that one - my gut reaction is “that just isn’t do-able” but sometimes an idea comes later.
I had to persevere on this, and managed to get it working with this:
{exp:channel:entries channel="news" limit="1"}
<?php
$this->EE =& get_instance();
$id='{entry_id}';
$res = $this->EE->db
->select('cat_name')
->from('exp_categories')
->join('exp_category_posts', 'exp_categories.cat_id = exp_category_posts.cat_id ')
->where('entry_id', $id)
->get()
->result_array();
foreach ($res as $r) {
$cats[] = $r['cat_name'];
}
?>
{exp:channel:categories channel="news" style="linear"}
<?php
$class="";
$category_name = '{category_name}';
foreach ($cats as $value) {
if ($value == $category_name) {
$class="active";
}
}
?>
<a href="http://{path=%27news/index%27}" class="<?php echo $class?>">{category_name}</a>
{/exp:channel:categories}
{/exp:channel:entries}
