PHP - XML Request without PEAR

[maifithc]

I've been doing PHP for 6 years now and can write most systems in a few days, but I have never looked into XML much, even though I know I should.

Here is my problem :

<?php
$url = "http://www.e-travelsolution.com/xml/xmlpostreceiver1-0.asmx/ET_SO_HT_001";
 
$data = "<?xml version='1.0' encoding='utf-8' ?>
<Request Type='List' Version='1.0'> {List, Reservation, Content}
<Header>
<Product>Hotel</Product>
<Affiliate_Id>test</Affiliate_Id>
<Request_Id>test".time()."</Request_Id>
<Timestamp>".date("Y-m-d",time())."T".date("H:i:s")."</Timestamp>
<Language>ING</Language>
<Currency>US</Currency>
</Header>
<ArrivalDate></ArrivalDate>
<ReturnDate></ReturnDate>
<Destination></Destination>
<MealPlan></MealPlan>
<Category></Category>
<City></City>
<Hotel_Name></Hotel_Name>
<Max></Max>
<New>No</New>
<Inmediate_Conf>YES</Inmediate_Conf>
<Text>YES</Text>
<Order_Id>".$_GET['order_by']."</Order_Id>
<Order_Di>".$_GET['ascdesc']."</Order_Di>
</Request>";
 
$req =& new HTTP_Request($url);
$req->addHeader("Content-Type", "text/xml");
$req->addHeader("Content-Length", strlen($data));
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$req->addRawPostData($data, true);
$req->sendRequest();
echo $req->getResponseBody();
 
?>

This gives me : Fatal error: Cannot instantiate non-existent class: http_request in /u/t/travyuc/www.travelyucatan.com/hotels_list.php on line 29

:(

Any help would be appreciated. I am trying to get an XML response from the XML posted submission. Their specific instructions were to post an XML request to generate an XML response.

Well pear isn't installed so that kinda sucks. Any other way to post an XML request?

Not sure why you can't just install/enable pear. Anyways:

So, I got the host to install the pear modules i needed, but now i am getting an error instead of a response. Here is the code I have :

[PHP]<?php

$url = "http://www.e-travelsolution.com/xml/xmlpostreceiver1-0.asmx/ET_SO_HT_001";

$data = "<?xml version='1.0' encoding='utf-8' ?>
<Request Type='List' Version='1.0'>
<Header>
<Product>Hotel</Product>
<Affiliate_Id>USERNAME</Affiliate_Id>
<Request_Id>USER".time()."</Request_Id>
<Timestamp>".date("Y-m-d",time())."T".date("H:i:s")."</Timestamp>
<Language>ING</Language>
<Currency>US</Currency>
</Header>
<ArrivalDate>".$_GET['AD']."</ArrivalDate>
<ReturnDate>".$_GET['DD']."</ReturnDate>
<Destination>".$_GET['DEST']."</Destination>
<MealPlan>".$_GET['MP']."</MealPlan>
<Category>".$_GET['CAT']."</Category>
<City>".$_GET['CITY']."</City>
<Hotel_Name>".$_GET['HN']."</Hotel_Name>
<Max>".$_GET['MAX']."</Max>
<New>No</New>
<Inmediate_Conf>YES</Inmediate_Conf>
<Text>YES</Text>
<Order_Id>".$_GET['order_by']."</Order_Id>
<Order_Di>".$_GET['ascdesc']."</Order_Di>
</Request>";

require 'HTTP/Request.php';
$req =& new HTTP_Request($url);
$req->addHeader("Content-Type", "text/xml");
$req->addHeader("Content-Length", strlen($data));
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$req->addRawPostData($data, true);
$req->sendRequest();
echo $req->getResponseBody();

?>[/PHP]

What is the error? It would help to find the problem.

[maifithc]

This is the error :

Error #0: Pag: www.e-travelsolution.com PEAR HTTP_Request class ( http://pear.php.net/ ) Originado por: .getDataReader  91  Object reference not set to an instance of an object.  IPDMCZ0431MIA

What version of PHP are you using? Many of these problems are associated with PHP before 4.2

[maifithc]

I'm using version 4.2.3.

I know there are earlier versions, but the error seems to be coming from their end. I am at least getting some sort of response. I am just wondering what the error means so maybe I can fix it from my end.
