log.php

// Test
function logErrorElmahIO($logID, $title, $application, $critical = '0', $detail = '', $user = '') {

  $ch = curl_init(); 

  if ($critical == '1') { 
    $criticalStatus = "500"; 
  } else { 
    $criticalStatus = "100"; 
  } 


  $data = array( 
    "title" => $title, 
    "application" => $application, 
    "statusCode" => $criticalStatus, 
    "detail" => $detail, 
    "hostname" => $_SERVER['HTTP_HOST'], 
    "user" => $user, 
    "url" => $_SERVER['REQUEST_URI'] 
  );

  $data_string = json_encode($data); 
  $a = "https://elmah.io/api/v2/messages?logid=$logID";

  curl_setopt($ch, CURLOPT_URL, $a); 
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 
  curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
  curl_setopt($ch, CURLOPT_HTTPHEADER, array( 
    'Content-Type: application/json', 
    'Content-Length: ' . strlen($data_string))
