Loop thru QueryString

[davman2002]

I want to know if anyone know how to loop thru a querystring of Checkboxes and determine which ones have been checked? What I actually want to do is determine which checkboxes have been selected and then based on that information update the database.
Here is what I currently have and it does not seem to work

<%
strB1(0) = Request.QueryString(&quot;B1&quot
strB1(1) = Request.QueryString(&quot;B2&quot
strB1(2) = Request.QueryString(&quot;B3&quot
strB1(3) = Request.QueryString(&quot;B4&quot
strB1(4) = Request.QueryString(&quot;B5&quot
strB1(5) = Request.QueryString(&quot;B6&quot
strB1(6) = Request.QueryString(&quot;B7&quot
strB1(7) = Request.QueryString(&quot;B8&quot
strB1(8) = Request.QueryString(&quot;B9&quot
strB1(9) = Request.QueryString(&quot;B10&quot
strB1(10) = Request.QueryString(&quot;B11&quot
strB1(11) = Request.QueryString(&quot;B12&quot
strB1(12) = Request.QueryString(&quot;B13&quot
strB1(13) = Request.QueryString(&quot;B14&quot
strB1(14) = Request.QueryString(&quot;B15&quot
strB1(15) = Request.QueryString(&quot;B16&quot


'Determine which Basic Information buttons were checked

BCounter = 0
Counter = 0

While Counter < 16

If strB1(Counter) = &quot;ON&quot; Then
If Counter = 0 Then
MyArray = strB1(Counter)
Else
MyArray = MyArray & &quot;,&quot; & strB1(Counter)
End If
End If
Counter = Counter + 1
BCounter = BCounter + 1
Wend

strB_info = Array(MyArray)

'Used for testing
Response.Write MyArray
%>

Well, firstly, only the ones that were checked will be passed, but since you are referncing each one as a string what you can do is build a for loop (if you know how many there are) and build those checkbox query names dynamically, like so:

For i = 0 to 10
   strB(i) = Request.QueryString("B"&i)
Next

Anothe method is to loop through all the values that were passed in the querystring and then only grab the B's. I would deem this to be less efficient however, as you will be checking every single input that was passed and have to check if it is a B than grab the number off of the name.

Hope this helps,
