so my question is how i make sure the paypal form isnt going to get edited by a user on my website.
the form tags are of the "hidden" type but a quick look at the source code lets you change that.
if a line of the form is:
<input type="hidden" name="amount" value="71">
how can i make sure someone doesnt change it to
<input type="hidden" name="amount" value="1">
and pay 1 dollar for the item, since paypal is going to process his request.
is there a way to post a form like this using PHP where the end user cannot change its parameters on the fly? its really important. if people would attempt fraud then i wouldnt care but im very sure someone would try to do thus.
thank you for all the suggestions, and sorry if its not a very specific "question"
could i use this maybe?
