Since yesterday I am trying to figure out checkboxes in APEX, which should be simple, however I have failed to make even the simplest scenario work.
Here is what I did so you can tell me what I did wrong.
I have three tables:
create table semester( id number not null, name varchar2(30) not null, primary key(id) ); create table subject( id number not null, name varchar2(30) not null, primary key(id) ); create table semester_subject( id number not null, semester_id number not null, subject_id number not null, primary key(id), foreign key(semester_id) references semester(id), foreign key(subject_id) references subject(id), constraint semester_subject_uq unique(semester_id, subject_id) );
I have created in apex a region with one select list with the following list of values:
select name d, id r from semester order by 1
and one report with the following query
select apex_item.checkbox2(10, id, 'UNCHECKED') "id", subject "Subject" from subject;
Also I have one button to submit the page.
What I want is to insert the ids of the subjects with the ticked checkboxes, in the semester_subject table, together with the id of the semester selected from the select list.
So I made this on submit process:
DECLARE v_subject_id subject.id%type; v_semester_id semester.id%type; BEGIN v_semester_id := :PX_SEMESTER; FOR I in 1..APEX_APPLICATION.G_F10.COUNT LOOP v_subject_id := APEX_APPLICATION.G_F10(i); insert into semester_subject(semester_id, subject_id) values(v_semester_id, v_subject_id); --I have a sequence and a trigger for the id END LOOP; END;
On my VPS when I submit the page I get 404 error "The requested URL /apex/wwv_flow.accept was not found on this server".
So I created a workspace on apex.oracle.com, there the page reloads and I get the success message from the process, but when I check the table semester subject, the data isn't inserted.
Any ideas on what I'm doing wrong? Thanks in advance for your help.
