Hi,
I need to pass values to a payment processor following a purchase, I am entering the new order from an ASP page and then redirect to the payment processor, I could pass the variable such as the price, order ID etc using the string and this works, however if the user change the string and reload then they will be charged a different amount etc..

Is there a way to pass the variable using the form post method without having to ask the user to click on the button to be redirected?

Thanking you in advance
Olivier

Use the XMLHTTP object. You can do an HTTP Post or Get from ASP code using this object.

MrWizard, can you please show us an example of posting data to a field, using POST method?
for example, if i have an html form with 2 fields, username and password, how can i pass values to both of these fields by using XMLHTTP?

thanks in advance.

You don't post data to a field... you post it to a page, and the asp code on the page can put it into a field.

You can just google on XMLHTTP and you'll get a lot more.
