Snoopy

P: n/a
I need to access a website, Fetch the data, and then logout. Please
tell me where I am wrong. I dont think its logging out properly.

<?

include "Snoopy.class.php";
$snoopy = new Snoopy;

//Logging in
$submit_url =
'http://www.sortingcodes.co.uk/FormsLogin.asp?action=login&URL=Default%2Easp';
$submit_vars["Username"] = "Username"; //my username
$submit_vars["Password"] = "Password"; //my password
$submit_vars["Submit"] = "Go";
$snoopy->submit($submit_url,$submit_vars);

//Requesting for info
$snoopy->setcookies();
$submit_url =
'http://www.sortingcodes.co.uk/Results.asp?type=Sortcode&Page=1&Sortcode=402343';
$snoopy->fetch($submit_url);
echo $snoopy->results;

//loggin out
$snoopy->setcookies();
$snoopy->fetch("http://www.sortingcodes.co.uk/logout.asp");

?>

Thanks

What is Snoopy? It would appear most the functionality you're using is in
that class. We need to see that if we're going to help you.

What are you actually trying to achieve by logging in and out of another
website?

What is Snoopy? It would appear most the functionality you're using is in
that class. We need to see that if we're going to help you.

What are you actually trying to achieve by logging in and out of another
website?

// Snoopy will use cURL for fetching

I'll try and help through a process of illimination.

Are you using this class on your own server where you control everything in
the environment, or are you using virtual hosting? This class uses the
actual cURL library rather than the built in php functions, so wants to know
the actual location of cURL.

Have you had ANY success using this class? Using the inbuilt PHP curl
libraries can achieve a similar result to Snoopy (except Snoopy has methods
to make it easier to extract information from the result data.)

P: n/a
There is no SSL its just cookies that I have to handle and that gives
me the problem. Cookies are quite difficult to get through. Using the
code I mentioned above and snoopy, I can actually login, fetch the data
and then logout. The problem is when I try to login again sometimes it
works and sometimes it doesnt.

Can CURL handle cookies or do we pass the cookies? Can you give me an
example please.
Thanks
