XML and PHP - HELP???

[Nicksta]

Hi there guys!

Please can someone help - maybe someone has done something similar!

My payment gateway needs me to do the following!

Right,

An IA_Auth method allows for the merchant to initiate an Internet Account payment pre-order/staged order.

The IA_Auth XML tag is represented as <IA_Auth> (opening tag) and </ IA_Auth > (closing tag).

NOTE: All Transaction input XML documents must be sent to https://secure.SafeShop.co.za/s2s/SafePay.asp.

WARNING: All XML tags are case-sensitive. If the case of the XML tag is not set to the correct case, SafeShop™ will issue a failed XML transaction. Sample 34 demonstrates the minimum IA_Auth input Transaction XML document that will be sent to SafeShop™ for processing. <?xml version="1.0" ?> <Safe> <Merchant> <SafeKey>{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}</SafeKey> </Merchant> <Transactions> <IA_Auth> <MerchantReference> SafeShop_Pro_3/4/2002 3:29:20 PM </MerchantReference> <PaymentMethod>ican</PaymentMethod> <Amount>3200</Amount> </IA_Auth> </Transactions> </Safe>

So i tried to post the information - needless to say with no sucess. After asking for help this is what they sent me!

Our programmers have checked the information that you sent through and have told me that you are trying to POST the information to our server. You cannot POST to this server.

Even if you just go to http://secure.safeshop.co.za/s2s/SafePay.asp? you will see your error message.

What you have to do is PARSE the information to the server using the XML parser.

This is why you need the Php/XML Parse to send information also.

Any idea how to do the above - please guys im really stuck. Been looking and looking into that xml parse and its making no sense... my knowledge of xml is almost non-existent.

Thanks again for any help!

generally you are supposed to post XML, this is what we do to our payment gateway. the most common thing to use is called CURL. http://curl.haxx.se/
as for creating your own XML, it is VERY easy... you just have to follow the form that they give you. it is like HTML with tags.. but instead of representing visual elements it is representing data

I have been trying to use curl -> this is what I did, but apparently it is wrong because I am POSTING it and not PARSING it...

Any idea's what im doing wrong??

if ($ch = curl_init()) {
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 120);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");

        $result = curl_exec ($ch);[/QUOTE] 

Thanks guys!!!!

Anyone???

Hi, many thanks for your reply.

Ok, I agree - maybe it was a bit broad question. Maybe being a bit more specific would help! I need to learn how to do this myself and want to learn - I just need to be edged in the right direction. I implemented other payment options on the website (eventually) but this one has REALLY got me stuck. Been working on it for 2 months now so you can imagine my fustration. I just dont understand what I am doing wrong. Ive gone through tons of different RPC addons, and other mods from PEAR that people have recommended. But I think im going in the complete wrong direction.

Basically, in a nutshell. What needs to be done. Im going to have a xml document - eg :
<?xml version="1.0" ?> <Safe>Test</Safe> which i need to send to the payment gateway server somehow.

Now i have been using curl

function DoTransaction() {
$url = PGXML_SERVICE;
$data = $this->XMLAuthRequest();

    if ($ch = curl_init()) {
        curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt ($ch, CURLOPT_URL, $url);
        curl_setopt ($ch, CURLOPT_POST, 1);
        curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt ($ch, CURLOPT_HEADER, 0);
        curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt ($ch, CURLOPT_TIMEOUT, 120);
        curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");

        $result = curl_exec ($ch);[/quote]

but this is clearly incorrect. I done tons of research and cant seem to find ANYTHING that applies. They say PARSE the information to the server, not post - but the only parse I can find is the one's that "extract" the information out of the variables

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");

Can anyone point me in the right direction?? Thanks again guys!!! 🙂🙂

I am most certain that there is a communication breakdown somewhere... the term "Parse to the server" makes no sence at all... maybe it would help if you could directly talk to the tech team at your gateway!
