Hello, for one of my projects I would like the user to select the sorting column of a table. On zope.org this is done in the product download page, you can click on a column title and this column will become the sorting column. Yes, I looked at the DTML-SOURCE with the link at the bottom of the page. I revieled that the main work is done in two sub function "sort_link" and "SiteIndex". sort_link will rewrite the QUERY_STRING to reflect the correct sorting column and for a second click the reverse option and SiteIndex will produce the results in excat that order. How can I have a look at these two methods?
