Adding a Sortby 'old/new' dropdown for articles

Hey Guys,

I am trying to add a sortby dropdown option for my articles.

The option to select the order of display is in the advanced tab section but i'd like to provide that option in the front end.

Allowing users select what order they'd like to see. (Newest/Oldest).

I tried this -
<li><a href="[[~[[*id]]? &sortby=`ASC`]]">Newest</a></li>
<li><a href="[[~[[*id]]? &sortby=`DESC`]]">Oldest</a></li>

That didnt work.

Any suggestions/solutions will be welcomed

I assume that you're using getResources or pdoResources for the search. The trouble is that they don't know what's in the URL. You need a custom snippet to get the query parameter from the URL:

In the getResources tag:



Then a custom snippet:



Also, your tags above are incorrect (you can tell by looking at the URL, which should have ? &sortby=`ASC` at the end). The parameter goes inside the link tag with no question mark:



I always have to look at my own book to get this right.

You could also use placeholders and a little more code in the snippet so the user would see something like:

Sorted By Newest -- Sort by Oldest

or

Sorted by Oldest -- Sort by Newest
