cURL POST to REST Service

Question

Hi,

I am trying to post to a REST service using PHP cURL but I'm after running into a bit of difficulty (this being that I've never used cURL before!!).

I've put together this code:

  <?php
error_reporting(E_ALL);
if ($result == "00")
{

$url = 'http://127.0.0.1/xxxxxx/AccountCreator.ashx'; /*I've tried it a combination of ways just to see which might work */

$curl_post_data = array(
    'companyName' =>urlencode($companyName),
    'mainContact' =>urlencode($mainContact),
    'telephone1' =>urlencode($telephone1),
    'email' => urlencode($email),
    'contact2' => urlencode($contact2),
    'telephone2' => urlencode($telephone2)
    'email2' => urlencode($email2);
    'package' => urlencode($package)
    );

foreach($curl_post_data as $key=>$value) {$fields_string .=$key. '=' .$value.'&';
}
rtrim($fields_string, '&');
die("Test: ".$fields_string);

$ch = curl_init();

curl_setopt ($ch, CURLOPT, $url);
curl_setopt ($ch, CURLOPT_POST, count($curl_post_data));
curl_setopt ($ch, CURLOPT_POSTFIELDS, $fields_string);

$result = curl_exec($ch);

curl_close($ch);

Following this, my code sends an email and performs an IF statement. I know this works okay, I only started running into trouble when I tried to insert this cURL request.

I've tried this however it doesn't run. As I am integrating with payment partners, it just says:

Your transaction has been successful but there was a problem connecting back to the merchant's web site. Please contact the merchant and advise them that you received this error message. Thank you.

The exact error that was received was a HTTP 500 error.

Thanks.

Answer 1

foreach($curl_post_data as $key=>value) {$fields_string .=$key. '=' .value.'&';

value here is missing a dollar i guess

foreach($curl_post_data as $key => $value) {$fields_string .=$key. '=' .$value.'&';

have you tried die($fields_string); to see what are you actually sending to the merchant?

Answer 2

First of all: are you testing locally? Because that IP you're using is not a valid server address.

The constant to set the URL is called CURLOPT_URL:

curl_setopt ($ch, CURLOPT_URL, $url);

Also CURLOPT_POST must be true or false ( http://php.net/curl_setopt ), not a number (except for 1 maybe):

curl_setopt ($ch, CURLOPT_POST, true);

Have a look at http_build_query
