Great idea! I never thought about that before. After a few moments of happy hacking, I've pieced together two changes to A:X:QueryParam: ---- =head2 C<<param:get name="foo" index="1"/>> Get a value from the given parameter. The "name" attribute can be passed as a child element for programattic access to parameter values. If the index attribute is supplied, and if multiple parameters are supplied for the same "name", then the appropriate parameter is returned. If multiple values for the same parameter are given, but no index is supplied, the first value is returned. Now, if you can understand that convoluted set of instructions, then you're smarter than me! =head2 C<<param:count name="foo"/>> Returns the number of parameters provided on the request. If a name is provided, the number of parameters supplied for the given name is returned. If the name is left out, then the total number of parameters is returned. ---- This code is *completely* untested, since my development server has been taken by my SysAdmin for some emergency server replacement work, so if anyone wants to grab the latest copy out of CVS and try it out, go for it. If you do try it out, let me know if it works / fails, so I can release it to CPAN or fix the bugs, respectively: http://cvs.nachbaur.com/cgi-bin/viewcvs.cgi/*checkout*/AxKit-XSP-QueryParam/lib/AxKit/XSP/QueryParam.pm?rev=1.2 -- /* Michael A.
