Dynamic link to different form and parameters

Question

Have a few problems i would like some help on.
First i will describe what I’m planning to do.
And I'm sorry if it's a little of the normal way of doing it, but I'm new to the Portal
Have a list over different trip people shall have possibility to join,
Some of those trips can are for the person only and others for the whole family.
So my plan is to show a list of all the trips and then a status saying if
they already has join it or not.
Then the person can press the trip (link) and depending on some data,
they would be transferred to 2 different forms. One for 1 person trip and another for a x person trip.
Like:
Trip     | Status | Personal/family
Golf     | New     | Personal - if pressed open form1
Boat     | New     | Personal - if pressed open form1
Dinner     | New      | Family - if pressed open form2
Soccer     | Accepted |Personal - if pressed open form1
Tennis | Declined | Personal - if pressed open form1
I made a report, showing all trip, but i can only make it use 1 link to form1, how do i make the link dynamic
The next problem is when i open form1, i would like to do some stuff in PL/SQL (Before Page).
But I have tried to get the parameters from the URL and I cannot get it to work.
I use something like, but the l_names.count is 0
....portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=1380125721&p_arg_names=_sessionid&p_arg_values=&p_arg_names=ENROLL_ID&p_arg_values=5677&p_arg_names=_enroll_id_cond&p_arg_values=%3D
DECLARE
l_names owa.vc_arr;
l_values owa.vc_arr;
l_lang varchar2(100) := PORTAL.wwctx_api.get_nls_language;
l_enroll_id NUMBER;
BEGIN
PORTAL.wwpro_api_parameters.retrieve(l_names, l_values);
FOR i in 1..l_names.count
LOOP
IF l_names(i) = 'enroll_id' THEN
     l_enroll_id:= l_values(i);
END IF;
END LOOP;
END;
What i also want to do is in some cases. Is create a row in a table and populate the form1 with it in the "before page", instead of using query from parameters.
Like:
Trip     | Status | Personal/family
Golf     | New     | Personal - if pressed open form1 and insert data and populate the form with the inserted data
Soccer     | Accepted |Personal - if pressed open form1 and do the standard query
How do I do that?

Answer 1

One way to do this would be to hold the urls for the pages you need to display in a table. You could then build the links as one of the columns of a report using some fancy SQL.<br>
<br>
Or you could make a simple function to return the correct link based on the relevant parameters:<br>
<br>
create or replace function get_url (p_criteria in varchar2) return varchar2<br>
is<br>
lv_url varchar2(500);<br>
begin<br>
if p_criteria = 'Personal' then<br>
lv_url := 'http://host:port/pls/portal/etc...';<br>
end if;<br>
etc...<br>
return '&LT;a href="' || lv_url || '"&GT;' || p_criteria || '&LT;/a&GT;';<br>
end;<br>
<br>
Your report could then include the function as one of the columns in your report.<br>
Not very elegant but it should do the job.
