Config.Inc.Php & My_Error_Handler

[banacan]

I have a site that uses config.inc.php, script 2.1 which has the error handler, my_error_handler. It has worked beautifully for me on many sites over the years but now I have a problem. My client has asked me to use a calendar script on the site, the script is EasyPHPCalendar. The problem is this script creates so many errors that my email box fills up - it causes 133 email error messages to be sent each time a page is loaded. Most of the errors are "undefined variables" or "use of undefined constant", there are also "undefined index" and "constant already defined" errors.

 

My question is how can I continue to use my_error_handler on this site without generating this plethora of errors? Right now I have commented out set_error_handler('my_error_handler') to avoid this problem.

 

The server php.ini file sets the error reporting to E_ALL & ~E_NOTICE,

the calendar script also has this: error_reporting(E_ALL ^ E_NOTICE);

 

Why am I getting these notices and how can I adjust the config.inc.php script to prevent this?

 

Many thanks.

If the calendar script is only used in one page or a few, reference the URLs of those pages in an array and check inside the config file whether you are on that page then if you are on a calendar script page then don't invoke the custom error handler. Not ideal but would at least stop the dreaded emails, I hate it when i get 5 or 6 saying you messed up. Let alone 133

Thanks for the suggestion Jonathan. Unfortunately the client wants to have a short list of events in the sidebar of every page, so that work-around won't do.

 

Thanks for responding though.

Well if yours is similar to mine

function my_error_handler ($e_number, $e_message, $e_file, $e_line, $e_vars) {

 

Can't you run a check to see the file that it came from? Wouldn't all the errors be from the same file? i.e calander.php (or whatever it is) regardless of the page?

Hey Jonathan,

 

I checked through the 133 error message emails and there are many different files responsible for the errors. However, the calendar script is all contained in one sub-directory, so do you think there is a way to exclude any errors created by files within a certain directory?

 

Thanks for helping.

I'm sure the path of the file is returned in the error message, so maybe use a regex or substring inside an if to tell if the file came from that sub directory and if it did, don't invoke it?

Well that works great. Here's what I have:

 

// Create the error handler.
function my_error_handler ($e_number, $e_message, $e_file, $e_line, $e_vars) {
global $debug, $contact_email;

// Don't display errors found if $findme is in $e_file
$findme   = '/calendar/';
$found = strpos($e_file, $findme);
if ($found === false) {

 // Build the error message.
 $message = "An error occurred in script '$e_file' on line $e_line: \n<br />$e_message\n<br />";

 //define timezone
 ini_set('date.timezone', 'America/Chicago');

 // Add the date and time.
 $message .= "Date/Time: " . date('n-j-Y H:i:s') . "\n<br />";

 // Append $e_vars to the $message.
 $message .= "<pre>" . print_r ($e_vars, 1) . "</pre>\n<br />";

 if ($debug) { // Show the error.

  echo '<p class="error">' . $message . '</p>';

 } else {

  // Log the error:
  error_log ($message, 1, $contact_email); // Send email.

  // Only print an error message if the error isn't a notice or strict.
  if ( ($e_number != E_NOTICE) && ($e_number < 2048)) {
   echo '<p class="error">A system error occurred. We apologize for the inconvenience.</p>';
  }

 } // End of $debug IF.

} // End of $found IF.
} // End of my_error_handler() definition.

 

I tested it to make sure that only those messages which are generated by a file with "/calendar/" in the string are excluded. Done.

 

Thanks for your suggestion.

No problem, glad it works for you.
