PHP Code If Then Statement help URGENT!

I am working on a site that is using osCommerce and using Payfuse to handle transactions.  The transactions are getting to Payfuse and processing correctly, however the cart is not completing the transaction and is reporting an error in the returned url, but it contains no error number.  When confirming the order, it returns the user to the payment screen with a URL parameter of error_ message which contains no value.  I am posting the class file, and the module file here.  Anyone that can help will be rewarded.  This needs to be fixed by Friday!  YIKES!  Thanks in advance for all your work!

Please Help!

I'm sorry I have not found a solution but I noticed that your useing:
$HTTP_GET_VARS
$HTTP_SERVER_VARS
$HTTP_POST_VARS
The new versions of these:
$_GET
$_SERVER
$_POST

They are superglobals and do not need to be made global.  Don't change your code.  Maybe your php is not the most current version, just thought I should mention it.

Do you have any idea at all which function is failing?
I understand you aren't getting any error message,
but you have to narrow it down some more.

If you can reproduce the error, then you should
trace through the process and add var_dump
commands to each function. Assuming you aren't
using Zend Studio, in which case you can set
break points.

Make note of which functions seem to complete
successfully and which one does not. Then
see what data is in the variables for that failing
function.

Hopefully, this gives you some insight on
troubleshooting you're issue.

I can tell you this is the redirect lines that is causing it....
      //if ($pf_xml_error) {
          //  tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYMENT, 'error_message=' . $result . ' - ' . urlencode(MODULE_PAYMENT_PAYFUSE_TEXT_DECLINED_MESSAGE), 'SSL', true, false));      
       // tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYMENT, 'error_message=' . $Pf_ErrMsg . ' - ' . urlencode(MODULE_PAYMENT_PAYFUSE_TEXT_DECLINED_MESSAGE), 'SSL', true, false));
      //}

However I am not sure of the error that is being caused.  When I comment these lines out all goes well.  Otherwise it seems to fail 100% of the time, even thought the funds are changing hands sucessfully.  If I check the variable $pf_xml_error it evalutes to 1.  So we need to trap out the error number one????

I have no idea....unfortunatly I am not a PHP coder, I am jsut trying to make this work before I head from this company.  Thanks for your help so far!

This is where $pf_xml_error is set:
$pf_xml_error = ($pf->doPayment() != PAYFUSE_TRANSACTION_OK);

If doPayment()'s output does not match the value of PAYFUSE_TRANSACTION_OK,
then $pf_xml_error should equal 1 (effectively boolean True). If they do equal,
it should set $pf_xml_error to 0 (boolean false and basically NULL in PHP).

The doPayment() function will return one of three constants:
    PAYFUSE_TRANSACTION_OK;
    PAYFUSE_TRANSACTION_DECLINED;
    PAYFUSE_TRANSACTION_ERROR;

Since the payment goes through, my guess is that you are not returning DECLINED.
So, that leaves ERROR. The trick now it to get the error to show itself.

In the class.payfuse.php file I would look at the doPayment() function near the bottom:

                $this->myErrorMessage = xml_error_string( $myError );
            }
            // Clean up our XML parser
            xml_parser_free( $this->parser );
        } else {
            // A CURL Error occured. Return the error message and number. (offset so we can pick the error apart)
            $this->myError = curl_errno( $ch ) + PAYFUSE_CURL_ERROR_OFFSET;
            $this->myErrorMessage = curl_error( $ch );

After each $this->myErrorMessage is set, I would probably var_dump($this->myErrorMessage)
to see what is going on. You may have to pipe them out to a file instead, but that is the place
where I think the error must be. If you can read it, maybe it will help you fix this thing.

I added the following code after each one at a time, replacing the var, and the text file always stayed blank.


                        $your_data = var_dump($this->myError);

                        // Open the file and erase the contents if any
                        $fp = fopen("error_log.txt", "w");

                        // Write the data to the file
                        fwrite($fp, $your_data);
      
                        // Close the file
                        fclose($fp);


Maybe I am doing ti wrong.

Brian BushSolutions ArchitectCommented:
Then in my opinion, you should just change the getError() function to this:

function getError() {
        if( $this->myError != 0 ) {
            // Internal Error
            return $this->myError;
        } else {
                    if($this->myResultProcReturnMsg == 'Declined')
                         return PAYFUSE_TRANSACTION_DECLINED;
                    else
                         return PAYFUSE_TRANSACTION_OK;
               }
    }

It ain't great, but I bet it will fix your issue.
The payfuse integration is in alpha, so it may be a bug.
