    @bruno17 - thank you so much - that worked!!!

    Just got to get getimagelist to work with geturlparam / if statement and i'm there! Current [if] statement displays only 1 news article when there are 2.

      and here is a bit more flexible filter-snippet:

      <?php

if (!is_array($subject)) {
    $subject = explode(',',str_replace('||',',',$subject));
}

return (in_array($operand,$subject));


      this should handle arrays, comma-delimited, double-pipe-delimited and sinlge-word tags

        @bruno17 - Thanks once again for your help.

        If I put this call on a page:
        [[getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news` &where =`{"tags:snippet:filterbytag":"announcement"}`]]

        It returns all values with the tag 'announcement'.

        If I try it conditionally:

        [[!If?
        &subject=`[[!getUrlParam? &name=`tag` &int=`0`]]`
        &operator=`news`
        &then=`[[getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news` &where =`{"tags:snippet:filterbytag":"news"}`]]`
        ]]

        It only returns one item. Any ideas? I have stripped back my getimagelist tpl to make sure there is no conflicts.

          does it work, when you call it this way:

          [[!getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news` &where =`{"tags:snippet:filterbytag":"[[!getUrlParam? &name=`tag` &int=`0`]]"}`]]


          and make sure to call it uncached since the result is dynamic.

          If you want to have cached results for each tag you can try to wrap it by getCache:

            It does but for some reason i get a double output (should be 2) but I get 4

            update: it did work! had a hidden snippet in my code that i thought was commented out, hence the duplication smiley [ed. note: jonleverrier last edited this post 11 years, 3 months ago.]

              Thanks so much for your help Bruno smiley All working nicely now!

              I'm using IF to display the results un-filtered on the news page, and if there is a filter applied to the URL, display the filtered results:

              [[!If?
&subject=`[[!getUrlParam? &name=`tag` &int=`0`]]`
&operator=`notempty`
&then=`[[!getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news` &where =`{"tags:snippet:filterbytag":"[[!getUrlParam? &name=`tag` &int=`0`]]"}`]]`
&else=`[[!getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news`]]`
]]


              Not sure I could of done this IF statement with output modifiers. Any way, thanks again Bruno smiley

                this will process the snippet-call twice each time.

                you can try it also this way:

                [[[[!If?
&subject=`[[!getUrlParam? &name=`tag` &int=`0`]]`
&operator=`notempty`
&then=`!getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news` &where =`{"tags:snippet:filterbytag":"[[!getUrlParam? &name=`tag` &int=`0`]]"}``
&else=`!getImageList? &tpl=`plug.tpl.news.item` &tvname=`tv.migx.news``
]]]]


                or this:
                [[!getImageList? 
&tpl=`plug.tpl.news.item` 
&tvname=`tv.migx.news`
[[!If?
&subject=`[[!getUrlParam? &name=`tag` &int=`0`]]`
&operator=`notempty`
&then=`&where =`{"tags:snippet:filterbytag":"[[!getUrlParam? &name=`tag` &int=`0`]]"}``
&else=``
]]
]]

                  Didn't realise you could nest IF statements in between snippet calls smiley

                  I've just tried adding 2 tags to one post "news, thoughts". For some reason MIGX still treats this as 1 string.

                  I filter by news and the tag with news (and thoughts) is excluded. I filter for thoughts, and there are no results.
