This is a ridiculously amazing Plug-in. It bests any I have ever used by far. So many applications for it, so much power!

I am trying to do an HTTP POST to create events in Google Calendar and FileMaker crashes when I set the "Content-length: " header.

W/o the content-length header I get a 411 error for No Content-length.

How do I debug or error capture this?

I can run the HTTP POST with JavaScript just fine. I use XmlHttpRequest() right from the webviewer and all works just fine. That POST does not require any Content-length and I would think that I really don't need it.

Some potentially related background: Without including CURLOPT_CUSTOMREQUEST => "POST", Google reads the request as a GET rather than a POST. I read a bit about this on the Google API forums and include the CURLOPT_CUSTOMREQUEST => "POST". The same forums warned that Google will try to redirect PHP / CURL and that I need to set some CURLOPT to get Google to return the expected XML (unfortunately it didn't say how).

I realize this is not a Google API forum, but I am new to PHP and am really just looking for a tip or two on how to trace this error w/o crashing FileMaker.

Here is the function:

// Include error handler
$errorHandlerCode = fm_get_variable('__HTTP_errorHandlerCode');
eval($errorHandlerCode);


// Set variables from request
$url = fm_get_parameter('url');

$data = "\n"
   . "  \n"
   . "  Test 9\n"
   . "  \n"
   . "\n";

$auth = fm_get_parameter('auth');
$message = fm_get_parameter('message');
$timeout = (int)fm_get_parameter('timeout');

$header[] = "Authorization: GoogleLogin auth=".$auth   ;
$header[] = "Content-type: application/atom+xml";
//$header[] = "Content-length: ".strlen($data);


// Get variables from memory
$proxyServer = fm_get_variable('__HTTP_proxyServer');
$authenticationType = fm_get_variable('__HTTP_authenticationType');
$userPassword = fm_get_variable('__HTTP_userPassword');

// Clear last info
$lastInfo = '';
fm_set_variable('__HTTP_lastInfo', $lastInfo);

// Branch for timeout (use default if a valid timeout is not supplied)
if (! is_int($timeout) || $timeout < 1) {
    $timeout = 30;
}

// Branch for progress bar
if (! empty($message)) {
    // Store current progress bar timeout setting (so it can be restored)
    $originalPBTimeout = fm_progress_bar_timeout();
    // Set progress bar timeout to be longer than request timeout so that it doesn't disappear early
    fm_progress_bar_timeout($timeout + 120);
    fm_new_progress_bar('pb1', 0, $message);
}

// Set https variables
$cert_file_path = FM_PHP_SUPPORT_PATH . 'ca-bundle.crt';
$ssl_verification = fm_get_variable('__HTTP_sslVerification') == 1 ? true : false;

// Branch for https (install cert file if necessary)
if (substr($url, 0, 5) == 'https') {
    // If the cert file doesn't exist, attempt to install
    if (! file_exists($cert_file_path)) {
        // Get cert file
        $cert_file_contents = file_get_contents('http://www.scodigo.com/downloads/smartpill/curl/ca-bundle.crt');
        // Branch for error
        if ($cert_file_contents == false) {
            errorHandler(ERROR_SSL_CERT_NOT_DOWNLOADED);
        }
        // Install cert file
        $cert_file_install = file_put_contents($cert_file_path, $cert_file_contents);
        // Branch for error
        if ($cert_file_install == false) {
            errorHandler(ERROR_SSL_CERT_NOT_INSTALLED);
        }
    }
}

$ch = curl_init();

}

curl_setopt_array($ch, $options);

// Get the url
$response = curl_exec($ch);

// Branch for error
if ($response == false) {
    // The curl error is sent as the additional description and we send die as false so that we can do some cleanup here before exiting
    $result = errorHandler(ERROR_CURL_ERROR, "\nCurl said: " . curl_error($ch), false);
} else {
    $result = $response;

    // Build last info

    foreach($info as $key => $value) {

    }
