Report with updateable checkbox

Question

Here is what I want to do :
I have a report with a HTMLDB_ITEM.checkbox on a 'Y', 'N' field. I would like to be able to update that value by simply checking and unchecking my generated checkbox.
Example : select player_no, player_name, htmldb_item.checkbox(1,active,'N','Y') from players.
I would like to be able to uncheck the active checkbox and the field value for that player(using the player_no) would be updated to 'N' and vice versa when checking the box.
I had created a process that looped on my checkbox item like explained in the "how to", but only the check items were processed.
Then I tried adding the following to my select and looping on the second item, but both items do not follow each other. If I have 2 checkbox checked and 10 players, than the item 1(checkbox) has only 2 records compared to 10 for item 2(hidden player_no):
htmldb_item.checkbox(1,active,'N','Y')||htmldb_item.hidden(2,player_no)
Is my request feasible ?

Answer 1

Sorry, I used HTML tags to bold stuff, didn't realize that didn't work.
Sorry for the slow response, I have been swamped with work.
I am assuming everyone is using the htmldb_application.g_fxx(i) variables in PL/SQL processes when trying to process their checkboxes.
Here's an example that would be similar to Patrick's situation (above). This would be in the SQL for the report region:
htmldb_item.checkbox(1, player_no, decode(active, 'Y', 'CHECKED', null) || htmldb_item.hidden(2,player_no)
Let me explain why I'm doing this:
First: htmldb_item.checkbox(1, player_no, decode(active, 'Y', 'CHECKED', null) will create checkboxes. Rows with active = 'Y' would have a checked checkbox, but the value of the checkbox is the player_no. I would assume (and suggest) that player_no is a unique value for that record.
Second: htmldb_item.hidden(2,player_no) will be the item you wish to update. (I always make this the primary key or unique value, so I can update any data for that record, and it must be the same value as the checkbox value)
In the How To documents, they tell you to use this for processing checkboxes:
for i in 1..htmldb_application.g_f01.count
loop
--process here
end loop; where htmldb_application.g_f01 is your checkbox item.
I have noticed that it only counts the rows that have a checked checkbox. So if you have a report with 10 rows, and you've checked 2 checkboxes, the count for that item is only 2. Where as, the count for you hidden items is 10.
There are two ways I have made this process work, but here is probably the easiest way I would process all rows (rows with a checked checkbox and rows without the checkbox checked):
/*this will loop through every row of the report*/
for i in 1..htmldb_application.g_f02.count
loop
/*this will account for when they don't check any boxes*/
if htmldb_application.g_f01.count != 0
then
/*this will loop through the checked checkboxes*/
for k in 1..htmldb_application.g_f01.count
loop
/*this compares the values of player_no of the checkbox and hidden item*/
if htmldb_application.g_f01(k) = htmldb_application.g_f02(i)
then
--process where checkbox is checked
update xtable
set active = 'Y'
where player_no = htmldb_application.g_f02(i);
else
--process where checkbox is not checked
update xtable
set active = 'N'
where player_no = htmldb_application.g_f02(i);
end if;
end loop;
else
--same process where checkbox is not checked
update xtable
set active = 'N'
where player_no = htmldb_application.g_f02(i);
end if;
end loop;
Now I this is not exactly the same thing I have in my process, but this is extremely similar, so excuse any syntactical errors I have made.
Let me know if this helps. I realize when I post this, all the spacing I have to make the code easier to read is gone, so I would suggest spacing things in notepad for easier reading.
If you want to see how to use all the htmldb_item package items then you can be found them in the HTML DB documentation: https://cwisdb.cc.kuleuven.ac.be/ora10doc/appdev.101/b10992/mvl_api.htm#sthref1469
