Simple ASP validation question

[jasonsalas]

Hi everyone,

I've never been good at validation, but this is the situation:

I've got a series of (26) buttons in an ASP 3.0 page, and the form can be submitted with none checked, but only a maximum of (15) can ever be checked. How would I validate against this?

Thanks!

first, since you mention them being checked, i assume you mean check-boxes and not buttons?

if that's the case, and assuming that these check boxes all share the same name, then the value returned will be a comma-delimited list as a single string. you could use the "split" function to create and array and check for the "ubound" of the array. that'd tell you how many options were selected. for example...

aryValues = split(request("chkboxes"),",")
if ubound(aryValue) > 14 then
 'code for too many options selected
else
 'code for data valid
end if

another angle would be to create a function that'd count the number of commas in the return value plus 1.

Thanks for the feedback. This is about what I'm doing - using checkboxes - you were right, but each having different NAME attribiute values.

Any other ideas?

I would suggest keeping all checkboxes one name.. and if you must know what the value represents for that checkbox then name the checkbox value what it is... if that makes sence.

if I helped.

oh an gaca, a simple way to get count of checkboxes checked is to do this..

Response.Write(Request.Form("chkboxes&quot.count)

if I helped.
