Some errors are only reported when all PHP error reporting is switched on. Without the error reporting on, you get the dreaded White Screen of Death. Check for errors behind the scenes As an alternative between showing no errors and showing all errors, you may wish to monitor the errors being generated by your site by running tail -f /var/log/apache2/error.log on your server. Change settings in your dev site You can show all errors by adding a few lines to your local testing site's settings.php: error_reporting(E_ALL); ini_set

All Exceptions must end with the suffix "Exception". All Exceptions should include an appropriate message and should not be translated. Only messages from https://www.drupal.org/docs/develop/coding-standards/php-exceptions the install and update system are currently translated as they are user facing. The Exception's message should include a hint to the values that caused the exception. Formatting messages should be done by concatenating strings or using sprintf(). Values should be surrounded by single quotes. DO NOT translate the message. DO NOT use SafeMarkup::format(). Exception classes should be named for the subsystem to which they relate, and the type of error. That is, [Subsystem][ErrorType]Exception. Exception Subclasses The use of subclassed Exceptions is preferred over reusing a single generic Exception class with different error messages as different classes may then be caught separately. Example: class WidgetNotFoundException extends Exception {} function use_widget($widget_name) { $widget = find_widget($widget_name); if (!$widget) { throw new WidgetNotFoundException("Widget '$widget_name' not found."); } } See the Drupal\Core\Entity\Exception namespace for real-life examples. Try-catch blocks Try-catch blocks should follow a similar line-breaking pattern to if-else statements, with each catch statement beginning a new line. Example: try { $widget = 'thingie'; $result = use_widget($widget); // Continue processing the $result. // If an exception is thrown by use_widget(), this c
developing- so you know when something isn't right even when everything http://definitivedrupal.org/err seems to be working fine, and even more when things http://drupal.stackexchange.com/questions/23775/is-there-a-way-to-trigger-an-action-on-a-php-exception-in-drupal-7 go wrong. The below code goes in settings.php (minus the opening and closing php tags; settings.php will already have opened PHP at the top of the file and you should not close PHP at the end of php error a document. error_reporting(-1); // Have PHP complain about absolutely everything.
$conf['error_level'] = 2; // Show all messages on your php error handling screen
ini_set('display_errors', TRUE); // These lines give you content on WSOD pages.
ini_set('display_startup_errors', TRUE);
?> Note that for the error_level configuration setting above 2 = ERROR_REPORTING_DISPLAY_ALL but that constant is not loaded yet, so we have to use the number 2. Originally inspired by and posted to Randy Fay's blog post, If you edit PHP code, please work with E_NOTICE turned on!!!. Note As noted, the configuration 'error_level' sets what level of warning and error messages are sent to the screen. As a general principle, though, how do you know what configuration variables are available for overriding in settings.php? You can see what values are presently in the variable table

Is there an easy way to do this with Drupal 7? Maybe an existing module or a combination of existing modules? I have a long, non-drupal technical background, and I've done this many times over in other frameworks and custom stacks (mostly Python). Not that all frameworks should be created equal, but I figured I'd ask if there was a module for this before going off and developing my own. I feel like I should be able to use the standard "recent log messages" for my purposes, but two things would need to be added to it. First, I would need to log php exceptions. Second, I would need to have the ability to send these log messages in an email. Now, I understand that logging php exceptions to the "recent log message" table wouldn't be totally all inclusive since the logging php code itself could have a bug in it. But if that was my only only limitation, I'll settle for the 95% solution. Any direction at all will be appreciated. 7 actions share|improve this question edited Oct 2 '13 at 12:47 kiamlaluno♦ 66.5k897192 asked Feb 28 '12 at 4:15 lkiss80 27839 Maybe I don't see the whole image...but why can't you just simply use try..catch with watchdog()?

I make questionnaires/challenges to Druplars in my local community, and this was a question there. PHP allows you to set error and exception handlers. This similar to how you register class autoloaders and shutdown functions. See set_error_handler Sets a user function (error_han
