The system works completely fine until i get to the site, then login and then this is displayed ..."The link you have used to enter the PayPal system is invalid. Please review the link and try again.".... but the screen before this (login page) has all the correct info on it so im really confused here :S.

[Maq]

Well what does the link look like?  What is it supposed to be?

 

You can probably just view source it or echo $link in the getLink method.

[jamesxg1]

does anyone know what im doing wrong here ? ???

[mrMarcus]

the paypal form is using the POST method .. but your 'action' is relying on GET.

 

just a quick observation.

oh :S, ermmm how do i change this ?

[jamesxg1]

i always thought that if a script is getting or posting something it only uses $_POST or $_GET :S

[jamesxg1]

does anyone have any idea please ???

[jamesxg1]

Or maybe, just maybe, you've annoyed everyone by being so impatient. The help and answers you might receive on these forums aren't something you're entitled to. People are giving up their own time in order to help, for free. I'm not going to sit here and claim they do it entirely out of their good nature - of course people gain something out of helping. However, you can't expect instantaneous replies to your questions. If it's that urgent, you should pay someone.

It could also be that, the information provided to us does not help us diagnose your problem. Given that this is technically a 3rd party script (I take it you got it from paypal) maybe you need to goto the sandbox help forums and ask them there why it is not working.

 

I never used paypals sandbox or the script they provide, so it could be simply that the information you are passing is invalid as the error suggests.

 

A rule of thumb, if you do not get an answer to your question within a day, chances are you have worded it wrong, you are posting in the wrong section, or you need to do some more research on your own to figure it out. As we cannot test what you have (nor would I want to) and without being able to actively test that script I cannot help resolve it. Sure I could make guesses, but they are just that. A guess, which could lead you in the wrong direction.
