Page Reference Selector counting grandchildren

[hezmann]

I have the following page structure

• Continents
  • Countries
    • Regions

I then have pages "walks" which has a multi-select Page Reference field Regions (I've tried using dynamic fields for this but it wasn't accomplishing what I needed) which has the regions listed by country and then the region (continent is more for searching later on so doesn't need to be seen here).

I'm trying to get a count of firstly all the walks within a continent, then country, then region but can't seem to figure out the selector for this.  

Thanks,

Heather

To be honest, I'm having a hard time understanding exactly what you need to accomplish . Even a simple mockup would help. Anyway, to your question.

I'm having a hard time understanding your setup. For instance, you say:

Do you have a single page called walks? (you say has a multi-selected page reference) OR you have multiple pages called walks. (you say I then have pages...).

Secondly, where is this "walks"?

Is the multi-select page reference field attached to the templates of both Continents and Countries? And more?

I'm asking in order to give you a definitive answer.  Irrespective, I believe what you want is either $pages->count("selector here") OR $page->numChildren("selector here"). Please note the differences as per the docs below:

thanks @kongondo - I think I need to approach this in a different way.  Still trying to wrap my head around the best way to accomplish things in ProcessWire.  Blessing and curse I guess with there being so many different strategies to accomplish the goal!
