Problem with checkbox and process

Question

Hallo,
I have a checkbox on my page and now I want to create a process that runs when the checkbox is checked.
What I want to do is: to ckeck wheather the checkbox is check and if this is then to set values.
I don't know if it is right how I check the status of the checkbox. What I also don't really know how I can decide
that all field I go through in the loop get the same value from the XYZ-collection. The value should be the last from
the XYZ-collection.
Thanks, Jade
declare
check integer:=0;
change integer:=0;
begin
check:=:Px_Check;
if (check <> 0) then change:=1; end if;
if change = 1 then
for i in 1..htmldb_application.g_f04.count
loop
htmldb_collection.update_member_attribute(p_collection_name=>'XYZ',
p_seq=>i,
p_attr_number=>5,
p_attr_value=>???);
end loop;
end if;
end;

Hi,
Taking the two issues separately....
1 - When dealing with checkboxes, you have to bear in mind that the submit process will only return the values of those checkboxes that have been ticked into the f04 collection (assuming f04 is the column containing your checkboxes). In order to determine which ones they are, you need to get the value (which should be a row number if you've created the checkboxes by using the Row Selector option) and then use that to get to the values on the actual rows. Something like:
DECLARE
vITEM NUMBER;
BEGIN
FOR i IN 1..HTMLDB_APPLICATION.G_F04.COUNT
LOOP
  vITEM := HTMLDB_APPLICATION.G_F04(i);
END LOOP;
END;Then, within the loop, you can use vITEM as the row number. So, if the user ticked items 1, 4 and 6. G_F04(1) would contain 1, G_F04(2) would contain 4 and G_F04(3) would contain 6. Therefore, for you update statement, you can use vITEM for the sequence number of the item to update.
2 - When dealing with collections, if you want to get to the last item in the collection, you can get the member count and use that to get to the member:
DECLARE
vCOUNT NUMBER;
vDATA NUMBER;
BEGIN
vCOUNT := HTMLDB_COLLECTION.COLLECTION_MEMBER_COUNT ('XYZ');
SELECT c005 INTO vDATA FROM HTMLDB_COLLECTIONS WHERE COLLECTION_NAME = 'XYZ';
END;That should get the c005 value for the last item and store it in vDATA. You can then update the ticked items with this value.
