How to filter and get count

[jhorii]

I have a collection of entries called "Programs" and I have a field that can show related "Testimonials" (another collection). For some reason the users want to have an active date range for a testimonial if applicable, so that it only appears within those dates.

So in my Programs antlers template, I need to get all the related testimonials where todays date is between the active date, and I also need to know the number of matches.

The only way I've been able to filter this data correctly is the following:

{{ related_testimonials }} {{ active_dates }} {{ if today | is_between:start:end }} {{ title }} {{ /if }} {{ /active_dates }} {{ /related_testimonials }}

The only problem is I also need to know how many of these filtered results there are. The reason is because if there is only one match, I just display one, otherwise I need to generate a carousel to scroll between them.

I can check the count of related_testmimonials with {{ if related_testimonials | count > 1 }} but that's before filtering.

How can I do this in antlers?

Make a custom modifier that does that filtering, then Antlers will return a {{ total_results }} variable, or something like that. Do a {{ dump }} inside the loop to see what vars are available.

Thank you, I'll give this a shot!
