ASP / Hidden text box issue

[Andrew Durstewitz]

Hi!

I am having a really strange issue. I have a few users calling in
saying they are getting an error. On further review I found this line is
what is causing it...

Set strLookup = cnAddStep.Execute ("SELECT * FROM ActionSteps WHERE
planId = '" & intPlanId & "' ORDER BY stepId DESC")

The exact peice causing it is intPlanId. For some reason the form
request isn't getting the ID.

intPlanId = Request.Form("hdnPlanId")

intPlanId is populated from a hidden text box in the previous page. But
only on a very few users machines will the post not occure. Any ideas?

Thanks,
Andrew J Durstewitz

This must be difficult to debug. Set your sql statements to a variable so
you can use response.write to verify what they contain.

? If the post did not occur, how could this asp code be executing?
Any ideas?

Are you using client-side code to put the value into the hidden textbox? If
so, does the client machine have scripting turned off?

Do any of the Form variables have values? Is it only this one that has no
value? If so, I would blame the client-side code.

Bob,

I have done this, for most users they get the ID, but for a VERY few
they don't get anything.

What I meant was that they are posting the page but the value of the
hidden form item isn't getting there.

The hidden form is being populated from the QueryString value passed to
it.

What I am starting to think is that the user has some sort of security
turned on that doesn't allow them to submit hidden data? Is that
possible?

The user is using IE 5.5.0

Not as far as I am aware - although that would be fun to have to code
around!

Best practice here would probably be to just view the source of the page
that has the form on it for one of the users.

This way you can see if the value is there or not in the hidden element. If
the hidden element doesn't have a value then its not retrieving the data
correctly in the first place (or you have records without these Id's etc)..

I'm betting that the form is sending the info correctly, and your next page
is processing it correctly, its just the values not getting to the form in
the first place...

Have a looky!

Regards

Rob

Using client-side code? Or a direct <%=request.querytring ...%>?

I've never heard of anything like this. Do you have any validation code to
ensure that this textbox has been populated before the form is submitted?

Is the problem intermittent, or does it always occur on a particular user's
machine?

The querystring could be the culprit. Check to make sure the hidden input is
being properly sent from the querystring.
i.e <input type="hidden" name="hdnPlantID" value="">

Umm...no, at least not form fields

Change the type to "text" and find out.

The user is using IE 5.5.0

I'm unaware of any version of IE that disallows hidden inputs. Any chance
the input sits outside the <form> tags?

Ok, I think I figured out the problem. I had the user attempt this on a
co-workers machine within the same organization. It worked.

It really sounds like to me that IE isn't running right for the user.

I have validated the data for the user. They are getting the data to
the page that has the hidden form but on post it losses it.

After a re-install of IE (maybe upgrade to IE6) hopefully this issue
will go away.

Thanks everyone,
Andrew

A hidden form field is often used to hold a value that is chosen from
some other source on the page. Is it possible that you are using
Javascript to populate the hidden field, and they have Javascript
turned off?

I'm not using a javascript to populate the feild. I am doing a
response.write into the feild it's self.

Also, keep in mind that it WORKS for 99% of users. It's just a few who
where having this problem.
