Listing Terms by Field Value Advice WordPress

  • SOLVED

Hey guys, you might have seen my other question as well. It's related to this, but please answer other question without regards to this.

I need to order a list of terms by the value of a custom field associated to the taxonomy terms.

I.e. My field is Star Rating and I need the terms to be listed from 5 star rating down to 0 stars.

The challenge for me is trying to figure out how this will work with pagination.

<strong>Solution Ideas</strong>

1) Is there is a way to tell my template (which is calling terms from my taxonomy) to order those terms by a field value?

2) If #1 is not doable, I am thinking I can create a template which calls 5 star groups first, then 4, 3, etc. using something like this:

if( get_field('star_rating', '100gridgroups_'.$lc->term_id) != 'star5' ) continue;

However, again, I'm not 100% sure how I can make the pagination work correct. Currently my pagination reads ALL the terms in my taxonomy and creates a new page after 12 terms. Perhaps if I leave my pagination structure as is, I can actually remove the call to get all my terms in alphabetical order, and then insert my if statements grabbing the star ratings in the order I want. I wonder if pagination will still work right.

UPDATE:

This is a template I'm currently using to display a paginated list of ALL my terms. Currently there is no sorting by star rating - it is by alphabetical order only.

John Cotton answers:

My understanding is that 5-Star, 4-Star etc are taxonomy terms. If that's wrong, then the following question is wrong as well.

Does the page that needs paginating contain a list of taxonomy terms, or posts that are tagged with the terms?

If the latter, what should the sorting be for posts that have the same term?

streetfire comments:

Hi John,

Let me clarify. 5-star, 4 Star etc are not terms. They are values of a custom field assigned to a term.

I.E.

Taxonomy: Grid 100 Groups
Term: Silver
Star Rating (custom field): 5 Star

The page that needs paginating is a list of taxonomy terms.

I will update my question with some code.

John Cotton comments:

Since you're using get_terms to retrieve the list, you'll need to add some code to hook in to the 'terms_clauses' filter.

Basically, you'll need to filter the join and order clauses of the get terms query to join to your custom field values and sort by that value.

Are you using Advanced Custom Fields or something like that for your taxonomy custom fields?

If so, the revised SQL will be a bit extended and difficult to advise on without actually seeing your database.

streetfire comments:

Yes I am using Advanced Custom Fields. I'm afraid your solution might be a bit out of my own reach to implement.
