How can I get the request path in CodeIgniter?

Question

I have a base controller that log errors and I want include in the log message ALL request data, ALL headers and request body. How can I do that in CodeIgniter?

Answer 1

CodeIgniter $this->input which is equivalent to file_get_contents('php://input') contains all the Body request (if any) an output from foo var_dump($this->input) would look like:

object(CI_Input)[9]
  public 'ip_address' => boolean false
  public 'user_agent' => boolean false
  public '_allow_get_array' => boolean true
  public '_standardize_newlines' => boolean true
  public '_enable_xss' => boolean false
  public '_enable_csrf' => boolean false
  protected 'headers' => 
    array (size=0)
      empty
  public 'security' => &
    object(CI_Security)[8]
      protected '_xss_hash' => string '' (length=0)
      protected '_csrf_hash' => string '' (length=0)
      protected '_csrf_expire' => int 7200
      protected '_csrf_token_name' => string 'ci_csrf_token' (length=13)
      protected '_csrf_cookie_name' => string 'ci_csrf_token' (length=13)
      protected '_never_allowed_str' => 
        array (size=10)
          'document.cookie' => string '[removed]' (length=9)
          'document.write' => string '[removed]' (length=9)
          '.parentNode' => string '[removed]' (length=9)
          '.innerHTML' => string '[removed]' (length=9)
          'window.location' => string '[removed]' (length=9)
          '-moz-bindin.......//and many other data.

and for the headers laso you have the new command in PHP 5.4 which is headers_list() . and also, many other data can be contained in the CI seesion like: ip_address, user_agent ,last_activity

Answer 2

For header details

$this->load->library('user_agent');
$reqUserIp = $this->input->ip_address();
$userAgent = $this->agent->agent_string();
$reqHeaders = $this->input->request_headers();

Answer 3

You could use a post controller hook .

• Enable hooks in application/config/config.php .

• Then in application/config/hooks.php ;

   $hook['post_controller'] = array( 'class' => 'PostController', 'function' => 'log_it', 'filename' => 'PostController.php', 'filepath' => 'hooks', 'params' => array() );

• Create a file in application/hooks/PostController.php

   <?php class PostController { private $ci; private $filepath; public function __construct() { $this->ci =& get_instance(); $log_path = ($this->ci->config->item('log_path') != '') ? $this->ci->config->item('log_path') : APPPATH.'logs/'; $this->filepath = $log_path.'action_log'; } public function log_it($log_message=NULL) { if ($log_message == NULL) { $log_message = date('d/m/YH:i:s')."::"; $log_message .= $this->ci->session->userdata('username')."::"; $log_message .= $this->ci->input->ip_address()."::"; $log_message .= $this->get_client_ip()."::"; $log_message .= $this->ci->router->class."::"; $log_message .= $this->ci->router->method."::"; $log_message .= uri_string()."::"; if (isset($_POST)) { foreach ($_POST as $key => $value) { $log_message .= "[$key] => $value;"; } } $log_message .= "\\r\\n"; } $fp = fopen($this->filepath, FOPEN_WRITE_CREATE); fwrite($fp, $log_message); fclose($fp); } private function get_client_ip() { if (!empty($_SERVER['HTTP_CLIENT_IP'])) { //check ip from share internet $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { //to check ip is pass from proxy $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip = $_SERVER['REMOTE_ADDR']; } return $ip; } } ?>
