Solution 1

Some servers (especially requested with SSL) returns 500 in cases when some parameters of request is set incorrect.

To avoid «500 error» (for example) be sure to:

set proper "Referer: " header if needed, with

curl_setopt(CURLOPT_REFERER, 'http://site.com/ref_page');

set proper "User-Agent: " header, with

curl_setopt(CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');

Solution 2

$url  = "https://www.xxx.xxx";
$post = "";# all data that going to send

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT    5.0'); 

$exe  = curl_exec($ch);
$getInfo = curl_getinfo($ch);

if ($exe === false) {
$output = "Error in sending";
if (curl_error($ch)){
    $output .= "\n". curl_error($ch);
}
} else if($getInfo['http_code'] != 777){
$output = "No data returned. Error: " . $getInfo['http_code'];//as preline
if (curl_error($ch)){
    $output .= "\n". curl_error($ch);
}
}

curl_close($ch);

echo $output;

BTW: Make sure that CURL moduel is installed.

Okay, I want to make a HTTP_POST using cURL to a SSL site. I already imported the certificate to my server. This is my code:

$url  = "https://www.xxx.xxx";
$post = "";# all data that going to send

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0'); 

$exe  = curl_exec($ch);
$getInfo = curl_getinfo($ch);

if ($exe === false) {
    $output = "Error in sending";
    if (curl_error($ch)){
        $output .= "\n". curl_error($ch);
    }
} else if($getInfo['http_code'] != 777){
    $output = "No data returned. Error: " . $getInfo['http_code'];
    if (curl_error($ch)){
        $output .= "\n". curl_error($ch);
    }
}

curl_close($ch);

echo $output;

It keep returned "500". Based on w3schools, 500 means Internal Server Error. Is my server having problem? How to solve/troubleshoot this?

Do you mean, I should contact my hosting company?

Sorry. Some typo mistakes. I was editing the code. I checked the code, the variable name is correct, it still gives me "Error: 500". Any idea? (i will edit my question, to avoid, confusion, thanks)

probably CURL moduel hasn't been installed yet in your server.

Hi SpawnCxy, the cURL module is installed. I was able to send to non-SSL site, using similar codes. Not sure if its about the SSL thingy

If you don't have direct access to server's logs, you may ask them to send them to you, yes.
