PHP performing on XML response

[Noonga]

I send off this:

 

<?php
$data = "<egateway>
		<eCardExpiryMonth>01</eCardExpiryMonth>
		<eCardExpiryYear>04</eCardExpiryYear>
		<eCardHoldersName>Joe Bloke</eCardHoldersName>
		<eCardNumber>4444333322221111</eCardNumber>
		<eCVN>123</eCVN>
		<eTotalAmount>100</eTotalAmount>
	</egateway>
	";
$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $edata);
curl_setopt($ch, CURLOPT_URL, "https://www.example.com/gateway_cvn/testpage.asp");
curl_exec($ch);
curl_close($ch);
?>

 

In return, I get the following XML:

 

<eResponse>
<eTrxnStatus>True</eTrxnStatus>
<eTrxnNumber>20219</eTrxnNumber>
<eAuthCode>123456</eAuthCode>
<eReturnAmount>100</eReturnAmount>
<eTrxnError>00,Transaction Approved(Test CVN Gateway)</eTrxnError>
</eResponse>

 

Is there a way to make it so this does not show, and instead I can make PHP do something like:

 

if (eTrxnStatus == True) {// do stuff};

 

?

use simpleXML...

have a look at the examples

[silkfire]

Would be easy with SimpleXML:

 

$data = '<egateway>
    <eCardExpiryMonth>01</eCardExpiryMonth>
    <eCardExpiryYear>04</eCardExpiryYear>
    <eCardHoldersName>Joe Bloke</eCardHoldersName>
    <eCardNumber>4444333322221111</eCardNumber>
    <eCVN>123</eCVN>
    <eTotalAmount>100</eTotalAmount>
</egateway>';

$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $edata);
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/gateway_cvn/testpage.asp');
$xml = simplexml_load_string(curl_exec($ch));

if ($xml->eTrxnStatus == 'True')
   echo 'It\'s true!';
else
   echo 'It\'s false!';

Joel,

 

That wouldn't help because I would not be able to set variables on the page being sent to me. Thanks anyway though.

 

 

silkfire. Thanks for that mate. I'll start reading into that string now to see how it works exactly.

 

Do you know how I can hide the response XML?

[Noonga]

I tried this, but am getting the same result as before. Have I mucked up?

 

$data = '<egateway>
    <eCardExpiryMonth>01</eCardExpiryMonth>
    <eCardExpiryYear>04</eCardExpiryYear>
    <eCardHoldersName>Joe Bloke</eCardHoldersName>
    <eCardNumber>4444333322221111</eCardNumber>
    <eCVN>123</eCVN>
    <eTotalAmount>100</eTotalAmount>
</egateway>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $edata);
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/gateway_cvn/testpage.asp');
$response = simplexml_load_string(curl_exec($ch));
if ($response -> eTrxnStatus == 'True') {
	echo "True 1111111111111.";
}
curl_exec($ch);
curl_close($ch);
?>

[silkfire]

Why are you executing the CURL again at the end?

 

curl_exec($ch);
curl_close($ch);

 

curl_close is not necessary. Is the echo not working? any errors you get?

[Noonga]

Yeah, I noticed the double execution myself and removed it.

I close $ch with curl_close() because that is how curl_close() is used in the PHP manual.

 

Correct, the echo is not working. all I see is the output response (the XML).

 

I am getting these issues in my error log:

 

PHP Warning:

simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '<' not found

simplexml_load_string(): 1

simplexml_load_string(): ^

 

PHP Notice:  Trying to get property of non-object

[silkfire]

It means that your XML response is malformed.

[Noonga]

Oh Dear. Thats what I thought aswell! This is the response I get:

 

<eResponse><eTrxnStatus>True</eTrxnStatus><eTrxnNumber>11673</eTrxnNumber><eTrxnReference/><eReturnAmount>100</eReturnAmount><eTrxnError>00,Transaction Approved(Test CVN Gateway)</eTrxnError></eResponse>

 

What could be wrong with it?

[Noonga]

I solved the problem with:

 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
