Curl request response not getting
Question
I am sending payment info to Virtual merchant payment gateway for payment system using curl. This is my code :
$Url= "https://www.myvirtualmerchant.com/VirtualMerchant/process.do";
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
// curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$fields = array(
'ssl_card_number'=>urlencode($_POST['ssl_card_number']),
'ssl_exp_date'=>urlencode($_POST['ssl_exp_date']),
'ssl_cvv2cvc2'=>urlencode($_POST['ssl_cvv2cvc2']),
'ssl_avs_address'=>urlencode($_POST['ssl_avs_address']),
'ssl_avs_zip'=>urlencode($_POST['ssl_avs_zip']),
'ssl_merchant_id'=>urlencode($_POST['ssl_merchant_id']),
'ssl_user_id'=>urlencode($_POST['ssl_user_id']),
'ssl_pin'=>urlencode($_POST['ssl_pin']),
'ssl_transaction_type'=>urlencode($_POST['ssl_transaction_type']),
'ssl_amount'=>urlencode($_POST['ssl_amount']),
'ssl_show_form'=>urlencode($_POST['ssl_show_form']),
'TransactionType'=>urlencode($_POST['TransactionType'])
);
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
// Download the given URL, and return output
echo $output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
print_r($output);
But in $output i am getting nothing, not any error or message. Am i doing it wrong ? please tell me ?

First I'd check your mechant_id, pin, etc. Below is working code I created after working through a similar problem.
<html>
<body>
<p>--start--</p>
<?php
//if you have a live account don't use the "demo" post url it won't work
$post_url = 'https://www.myvirtualmerchant.com/VirtualMerchant/process.do';
//replace the xxx's with your proper merchant_id, etc.
//they will give you these when you activate your account
//I've set form to not show, and ssl_result_format =>ascii to get a string returned
$fields = array(
'ssl_merchant_id' =>'xxxxxx',
'ssl_user_id' =>'xxx',
'ssl_pin' =>'xxxxx',
'ssl_show_form' =>'false',
'ssl_result_format' =>'ascii',
'ssl_test_mode' =>'false',
'ssl_transaction_type' =>'ccsale',
'ssl_amount' =>'1.44',
'ssl_card_number' =>'5000300020003003',
'ssl_exp_date' =>'1214',
'ssl_avs_address' =>'Test 3',
'ssl_avs_zip' =>'123456',
'ssl_cvv2cvc2' =>'123',
);
//build the post string
$fields_string = '';
foreach($fields as $key=>$value) { $fields_string .=$key.'='.$value.'&'; }
rtrim($fields_string, "&");
//open curl session
// documentation on curl options at http://www.php.net/curl_setopt
$ch = curl_init();
//begin seting curl options
//set URL
curl_setopt($ch, CURLOPT_URL, $post_url);
//set method
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//set post data string
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
//these two options are frequently necessary to avoid SSL errors with PHP
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$result = curl_exec($ch);
if($result === FALSE) {
//post failed
die(curl_error($ch));
} else {
//got a response
//some people seem to get name/value pairs delimited with "&"
//but currently mine is \n
//support told me there's no way to change it..
$response_array = explode("\n",$result);
//make it nice and useful
foreach( $response_array as $k=>$v ){
$v=explode("=",$v);
$a[$v[0]]=$v[1];
}
//show the whole array
print_r($a);
//use a specific return value
//returns "APPROVAL" if it went through
echo('<h1>'. $a[ssl_result_message] . '</h1>');
}
?>
<p>--end--</p>
</body>

The code above should net you a screen like this:
--start--
Array ( [ssl_card_number] => 50**********3003 [ssl_exp_date] => 1214 [ssl_amount] => 1.44 [ssl_customer_code] => [ssl_salestax] => [ssl_invoice_number] => [ssl_description] => [ssl_departure_date] => [ssl_completion_date] => [ssl_company] => [ssl_first_name] => [ssl_last_name] => [ssl_avs_address] => Test 3 [ssl_address2] => [ssl_city] => [ssl_state] => [ssl_avs_zip] => 123456 [ssl_country] => [ssl_phone] => [ssl_email] => [ssl_result] => 0 [ssl_result_message] => APPROVAL [ssl_txn_id] => AA49315-1234567-F78F-468F-AF1A-F5C4ADCFFB1E [ssl_approval_code] => N53032 [ssl_cvv2_response] => [ssl_avs_response] => [ssl_account_balance] => 0.00 [ssl_txn_time] => 01/15/2014 11:53:15 AM )
APPROVAL
--end--
Make sure you delete all these test purchases when you finished testing. I'm told they will inhibit your real purchases from posting.

You are calling an HTTPS page. Please refer to following link

Try to find error give this code before curl close:--
echo "Curl Error :--" . curl_error($ch);
if no error found do like this:-
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
then
print_r($result);
exit;

Try this:
$output = curl_exec($ch);
$response = curl_getinfo($ch);
echo "<pre>";
print_r($response);
echo "</pre>";
Hope you get the response :)
