Using a dynamic ID in gerResourceField

    HI All,

    I need to use a 'start id' that is set as a TV in a specific resource.

    This is the basic call i'm trying to make dynamic:

    [[getResourceField? &id=`298` &field=`longtitle`]]


    It seems that i can not nest another getResourceField to get this working:

    [[getResourceField? &id=`[[!getResourceField? &id=`[[*photoGalleryId]]` &field=`albumStart` &processTV=`1`]]` &field=`longtitle`]]


    I've also tried putting ID collector as a separate chunk which also fails.

    Any ideas?

      The problem there is that the snippet within the snippet is called uncached ([[!..), while the outer one is cached ([[..).

      What that means is that it will attempt to parse the outer snippet first (because it is cached), while the inner snippet isn't executed until later.. well, making it pointless. I've written about how nested and parsing order works on my blog last year: https://www.markhamstra.com/modx-blog/2011/11/nested-caching-in-modx-revolution/ - that should give you a bit more background on the subject.

      In other words: just call the inner snippet cached and you should be good to go.

        Hi Mark,

        Thanks for the hint. Oddly, I was sure that I had actually tried both cached and uncached! It's now working and that's what matters.

        Thanks again.
