I want to insert a wayfinder navigation section on each page in my site IF there are more than a certain number of child pages for the document, otherwise I want so show different content. Is this do-able and if so, how?
Very doable with a few options on how to do it. There may even be a snippet around that can load a chunk if doc has children (I think I remember seeing something like this).
1) If you are not a coder then you may consider installing PHx plugin and use that for the logic.
2) Build a wrapper snippet and use the MODx api to see if there are children or not. The getChildIds() function will return a list of children IDs for a document and you can simply see if there is a value, if true run snippet, else do nothing. Read about the wrapper snippet concept on this blog post:
