Displaying categories for a single post

Posted on by sanraul

If you know the ID of a post you can bind the category data by using code similar to: 

1
2
3
4
5
6
7
8

{post show="categories" post_id="{$post.ID}" assign_to="categories"}
 
<p class="category_links">
    {foreach $categories.data as $cat}
    <a href="{$cat.permalink}">{$cat.name}</a>
    {if $cat@last != 1}, {/if} {* add a comma is there is another category *}
    {/foreach}
</p>
{post show="categories" post_id="{$post.ID}" assign_to="categories"}

<p class="category_links">
    {foreach $categories.data as $cat}
    <a href="{$cat.permalink}">{$cat.name}</a>
    {if $cat@last != 1}, {/if} {* add a comma is there is another category *}
    {/foreach}
</p>

The result of this operation will bind a object with the following properties: 

1
