This is definitely beyond me. I tried adding that setTags snippet you suggested and I get a parse error.
Do you have any recommendations on who I could contact (even if I have to pay them) to get the functionality I want?
It works fine to use the tagLister call and click the tag name. Then I receive the results I want in the right place but that’s not how I need these pages to function. This seems like it should be pretty simple thing for MODx to do. I’ve read a couple other threads asking for the same thing and their solutions are not "user friendly", meaning there is no way I can ask my client to go through those hoops just to show a list of related resources.
Even if I could get the page to run
[[!tagLister? &tv=`tags` &target=`[[*id]]`]]
on page load, then I could hide it’s output with css, and the
[[!getResourcesTag? &elementClass=`modSnippet` &element=`getResources` &tpl=`relatedContentItem` &parents=`0` &resources=`-[[*id]]` &limit=`5` &includeContent=`0`
&toPlaceholder=`related` ]]
would function just fine.
