Lovely … I get to debug code in PHP
I made a test order and when I clicked confirm order the next page said page cannot be displayed or error page, I am not sure. Please place a test order and let us know if it is working properly.
Trouble ticket I recieved this afternoon.
And thus I started my descent into osCommerce, written in PHP of course.
It took long enough, but I was able to finally track the problem down to the following bit of code:
function tep_href_link( $page = '', $parameters = '', $connection = 'NONSSL', $add_session_id = true, $search_engine_safe = true ) { global $request_type, $session_started, $SID; if (!tep_not_null($page)) { die( error message with embedded HTML code, of course ); } if ($connection == 'NONSSL') { $link = HTTP_SERVER . DIR_WS_HTTP_CATALOG; } elseif ($connection == 'SSL') { if (ENABLE_SSL == true) { $link = HTTPS_SERVER . DIR_WS_HTTPS_CATALOG; } else { $link = HTTP_SERVER . DIR_WS_HTTP_CATALOG; } } else { die( yet another error message with embedded HTML code ); } // rest of function deleted }
catalog/includes/functions/html_output.php
The checkout code is running under a secure server
(secure.example.net) while the actual
site itself is under a different domain
(www.example.com) and for some reason, the
code, in generating the link, is getting things mixed up and the link is
being generated incorrectly. It's getting the secure server name
(HTTPS_SERVER) but tacking on the location on the non-secure
site (DIR_WS_HTTP_CATALOG) and thus leading to the dreaded 404 Not Found
error.
I'm not really keen on trying to debug this any futher than I have to (the osCommerce package comprises over 500 files), I basically changed the code to look like:
if ($connection == 'NONSSL') {
$link = HTTPS_SERVER . DIR_WS_HTTPS_CATALOG; // XXX - spc hack
} elseif ($connection == 'SSL') {
// rest snipped
It works (even if it is a hack). Customer is happy. I'm happy (that I no longer have to dig into this program).
Now back to the salt mines—the customer is now wondering why he isn't getting his email …
'tis to be expected I guess
I forgot about this. A few days the NAP of the Americas sent out a message about an upcoming maintenance window.
In Microsoft Word format.
Of course everybody uses Microsoft Windows.
Of course.
This would seem to explain their rather odd stance of not having a crash cart anywhere in the six story data center.
Because, you know, everybody uses Microsoft Windows. For everything. Including servers.
I'm getting less and less impressed with the NAP of the Americas.
Because, you know, everybody uses Microsoft Windows.
