Query for dynamic checkboxes

Show checked/unchecked using a recordset

This is a query to edit a users selected widgets with checkboxes.

How do you display a list of checkboxes from a database, for 1 user, showing checked for those that the user selected and unchecked for all other available widgets.



Something like this?
SELECT widgets.Name,widgets.ID,iif(Selections.WidgetID is NULL,""," selected ")
WHERE Users.UserID=193

while (!rs.eof){
<%=rs(0) + "<input type=checkbox name=" + rs(1) + " " + rs(2) + "><BR>"%>

I must have tried every combination of left, right, inner, outer join...Maybe theres a much easier way to get the same html output, Anyone know how to do this?

Why don't you just use the if statement on the recordset instead.

If rs(WidgetID) <> Null then
checkbox = selected
end if

Because I couldnt figure out how to get the recordset returned with nulls.

Bit of a mission, but I have sorted it now with two recordsets and a find.

time for a break :)

strSQL2="SELECT WidgetID FROM Selections WHERE UserID=" & varID
set objRS=objConn.Execute(strSQL)

set objRS2=server.CreateObject("ADODB.Recordset")
objRS2.CursorLocation= 3
objRS2.Open strSQL2,objConn, 1, 3

while not objRS.eof
Response.write "<input type=checkbox name='" & objRS(0) & "'"
objRS2.Find "WidgetID=" & objRS(0),,1,1 ' search foward from 1
if not objRS2.EOF then
Response.Write " checked "
end if
Response.Write ">" & objRS(1) & "<BR>"

I did it with a for loop. The data was entered csv, and I read it as csv, then parsed it into an array. Then, when it came time to check if the box should be checked, we just checked if the index matched the value.

Now this worked very well for a while, but with larger and larger recordsets it's becoming slower, so I will also try the "find" method.

I had to add a movefirst call, I dont know why it needs it as the find call specifies from 1.

objRS2.Find "WidgetID=" & objRS(0),,1,1

Its only an adminpage so wont get huge traffic and the options will stay at about 50, so this will do me for now. But I still think theres a way to return a single recordset with the IDs and true/false, some kinda wierd outer join......
