[SOLVED] Are there limits on the amount of data that can be posted via an ASP Form?

Phil · #1 Oct 23rd, 2007, 17:25

I have been working on a page to make ticket reservations online.

The "customer" completes a simple form that then posts this information to a second page. This second page does two things:

1. Enters this information into a database
2. Sends a confirmation e-mail to the "customer" and to myself

It appeared to be losing some of the posted data when I was carrying out tests on it.

Initially I thought that it might be the e-mailer code that was causing this problem, upon removing it the problem persisted.
I then decided to remove database code incase the problem was related to that code however this has still not resolved the problem.
As such the second page has now become a simple page to display what data has been posted.

You can view the page at www.camjazz.co.uk/reserve2.asp?ID=7 and the page it posts to www.camjazz.co.uk/rev.asp

It only appears to lose the show price, I have been led to believe by other sources that I may be trying to post too much data via the form.

Please can anyone help me to resolve this error.

I don't think the data is lost!

Maybe It's your calculation error! The second page does not get the show price value from the first page. You have to make a asp calculation in your second page in order to get the show price value.

Maybe something like this:

Code: Select all

 Ticket Quantity * 5.00 = show price

Can I see your calculation part on this one? and your second page code as well..

Sure but at the present the second page (www.camjazz.co.uk/rev.asp) does not make any calculations It just displays the data posted to it.

HTML: Select all

Mealcost(formatted) = <%=MealCost%><br />
<br />
 
This data was orignally posted by the form to this page.<br />
However incase I was attempting to post too much data I removed them from the form.<br />
<br />
Gig ID is now posted as a QueryString Variable<br />
<%Gig = Request.QueryString("ID")%>
Gig ID = <%=Gig%><br />
Posted is now calculated by this page rather than the Posting form.<br />
<%Function MediumDate (str)
    Dim aDay
    Dim aMonth
    Dim aYear
    aDay = Day(str)
    aMonth = Monthname(Month(str),True)
    aYear = Year(str)
 
 MediumDate = aDay & "-" & aMonth & "-" & aYear
End Function
 Posted = date()
 Posted = MediumDate(Posted)%>
Posted = <%=Posted%>
</body>

Hai Phil,

After looking your code line by line, I notice the typing error occur in line 247 of your code:

HTML: Select all

<input name="" nuts="" value="5.00" type="hidden">
<input name="meal" value="19.50" type="hidden">

I sure what you mean was this:

HTML: Select all

<input name="nuts" value="5.00" type="hidden">
<input name="meal" value="19.50" type="hidden">

Ah haa..! Please let me know the result, ok?

Phil · #5 Oct 26th, 2007, 08:34

Hi Monie,

You're absolutely correct, thats what was causing the error and here was me looking for something complex to be the reason, I'm a complete idiot.

Directly infront of me I'm going to write in BIG BOLD letters KISS Principle (Keep It Simple Stupid Principle) & Ockham's Razor.
Basically a reminder to keep things simple and the simplest answer/cause is probably the one.

BTW anyone interested can now view the fully functional and working reservations page at www.camjazz.co.uk/reservations.asp the second part is the same URL as before but now has some additional code to prevent posts without all of the necessary data.

Thanks yet again for helping me out monie

Monie · #6 Oct 26th, 2007, 08:43

No sweat Phil.

With Great power, comes a Great responsibilities, I would say...

Good luck with your sites..
