filter resources by tag

I’m developing a site for an art project. I started out in Evolution 1.0.3, but since then Revo 2.0.0 came out, so I decided to convert it before it was loaded with content.
In my Evo set up I have a tv called tagSearch. There’s a Ditto Call in there which ouputs a list of resources filtered by a tag defined in the tv ’myTags’.

An example:


My Evolution page with working Ditto functionality: http://claire.hi-ka-sk.be/modx/index.php?id=34

I’m searching for the same functionality with getResources and getResourcesTag, but I’m a bit stuck there.
In the documentation for getResourcesTag there’s an example which seems to be fitting my needs:

Display Resources with tag ’test’ (found in the GET param ’tag’) in the TV ’blog-tags’, and set the results to a placeholder called ’results’:

[[!getResourcesTag? &parents=`4,12,33` &tagKey=`blog-tags` &toPlaceholder=`results`]]

<h2>Search Results</h2>

[[!+results]]

But there’s a few things I don’t understand.
Where can I find the GET param? What does the &tagRequestParam do?
I have to be looking for a basic functionality but can’t seem to find it.
I’m doing this DIY style, without a technical developing background.
Thanks in advance,

Claire

As far as I understand, it should be used like this:
[[!getResourcesTag? &parents=`ID` &tag=`NameOfMyTag1, NameOfMyTag2` &tpl=`TemplateName` ]]

That’s because the default name for the tagRequestParam is ’tag’ so you can use &tag to filter your results ... But I can’t tell you for sure, because currently I’m not getting Taglister to work at all, it just outputs nothing ...

Another snippet "tagLister" generates the link with the parameter to specify which tag to display.
"getResourcesTag" snippet reads that parameter with GET method.
"&tagRequestParam" specifies the parameter name generated by tagLister and read by getResourcesTag.
( Default is "tag". ie &tag=xxxx )
