Display ONLY appropriat posts

If you’re on a category page (as dictated by the url which would be something like /template_group/category/category_url_title) then channel entries will by default only show entries that belong to that category.

Thats something I should have mentioned… I’m not on a category page, just a palin old channel entries page.

Thanks, Russ

In that case you could do it in several ways by using parameters in your channel entries tag:

Show all entries from any category belonging to a specific category group

{exp:channel:entries channel="mychannel" category_group="2"}

Show all entries from a specific category group and specific categories with ID’s 3,5,7 within:

{exp:channel:entries channel="mychannel" category_group="2" category="3|5|7"}

Show all entries from a specific category from any group

{exp:channel:entries channel="mychannel" category="3"}

Show all entries from several categories

{exp:channel:entries channel="mychannel" category="3|5|7"}

From the docs for reference: https://docs.expressionengine.com/latest/channel/channel_entries.html#id29 https://docs.expressionengine.com/latest/channel/channel_entries.html#id30

OK… Yeah… so I saw all of that, & I guess I’m on the right track then, but if my channel entry for products is assigned to categories 1,3, & 5,

How would I pass those ID’s into my Blog posts channel to display only blog posts in the sidebar that are assigned to those 3 categories?

Russ

Just use the category parameter like this.

{exp:channel:entries channel="mychannel" category="1|3|5" dynamic="no" limit="5"}

As its in your sidebar I’ve also added in the dynamic=no parameter to will ensure that EE doesn’t base results based on the URL segments, and a limit= parameter so you can lomit the number of entries displayed.

Have you considered related categories mode?
