Production environment: error page for fatal errors

[eluser]Unknown[/eluser]
Hi guys,

Do any of you know if there is a possibility to show a nice error page when a fatal error occurs? When you set the environment variable in index.php to 'production' the page just stays white, and I think it is convenient to show a page with some description.

Of course I could modify the default CodeIgniter code, but I would like to avoid that, so I am hoping one of you could help me out with some idea's.

You'd probably have to create a MY_Exceptions to create that functionality. But, there shouldn't be any fatal errors on a production box. That would indicate a bug that needs fixing.

Of course those needs fixing, but if there may occur a fatal error, for example, when a file is missing, it would be nice if there was something more than just a blank page, in general users do not know what to do with a blank screen.

So besides extending the core class there is no way this could be implemented? Well, it is way better than nothing. Thank you for your response.

You could create a custom error handler in a hook, using set_error_handler. I use one that emails me the error info.

Code:

<?php
function my_error_handling(){
function my_error_handler ($e_number, $e_message, $e_file, $e_line, $e_vars) {
  $message = "An error #" . $e_number . " occurred in script '$e_file' on line $e_line: \n<br />$e_message\n<br />";
  $message .= "Date/Time: " . date('n-j-Y H:i:s') . "\n<br />";
  $message .= "<pre>" . print_r ($e_vars, 1) . "</pre>\n<br />";
  if ( ENVIRONMENT == 'development') {
   echo '<p class="error">' . $message . '</p>';
  }else{
   error_log ($message, 1, ADMIN_EMAIL_ADDRESS );
   if ( ($e_number != E_NOTICE) && ($e_number < 2048)) {
    echo '<p class="error">A system error occurred. We apologize for the inconvenience.</p>';
   }
  }
}
set_error_handler ('my_error_handler',E_ALL^E_NOTICE);
}
/* End of file my_error_handling_hook.php */
/* Location: /application/hooks/my_error_handling_hook.php */

You could easily customize this to display whatever you want to the site visitor.
