getting request parameters in search generator using Request.getParameter()

[Dan <da...@porkfriedrice.net>]

Hi,

I have extended the default search generator that comes with cocoon to 
meet my requirements. One of these requirements is that searches can be 
limited to certain collections of documents. I implement this with 
checkboxes on the HTML form. For example, I have the following form:

[some query______________] query string

[*] Collection 1
[ ] Collection 2
[*] Collection 3

[Submit]


Ok, so when I submit the form the url looks something like this:

http://mymachine.com/webapp/search?queryString=some+query&colls=coll1&colls=coll3




In my search generator I want to get the request parameters so I can 
build the proper lucene query. The problem is that my checkboxes have 
the same name (colls) and when I try to do a 
request.getParameter("colls"), I only get the first checked box. How do 
I get them all?

here is the code segment:

// get collections to search
param_name = par.getParameter(COLL_PARAM, COLL_PARAM_DEFAULT);
if (request.getParameter(param_name) != null) {
     collection = request.getParameter(param_name);
}

System.out.println(collection);

So, using the query generated by my sample form above, I would see 
"coll1" printed in the logs and not coll3. I need to get both. How is 
this done?

Thanks!

  String[] getParameterValues(String name)
           Returns an array of String objects containing all of the 
values the given request parameter has, or null if the parameter does 
not exist.
