Answered Two getResources Questions

    I have a couple of getResources questions. First, is it possible for getResources to select random child resources. For example out of 30 child resources, can getResources randomly choose 10 of them?

    Second question. When getResources gets resources, does it index them, i.e. resource #1, resource #2, etc. I ask because, via php, I want to test each resource as it is gathered and test whether its index is even or odd. If its index is even, do THIS if its index is odd, do THAT.

    Thanks

      As far as fetching resoures you can &sortby=`RAND` and &limit=`10` but I am not sure how it fetches the results if it would fetch the first 10 and then sort them randomly.

      getResources does index the items. You can set the index start integer using the &idx property. Additionally, there are already templates available for &tpl, &tplOdd, &tplFirst, &tplLast and tpl_N.

      You can find all this and more properties on the getResources Doc Page: http://rtfm.modx.com/display/ADDON/getResources

      All the best,

          I'm pretty sure that sorting comes before limiting - it would have to, because if you don't know how to sort, how do you know which resources fall within the limit? So I expect this will do exactly what you want.
