Error Handler

Class \TYPO3\CMS\Core\Error\ErrorHandler is the default error handler in TYPO3.

Functions:

  • Can be registered for all, or for only a subset of the PHP errors which can be handled by an error handler
  • Displays error messages as flash messages in the Backend (if exceptionHandler is set to \TYPO3\CMS\Core\Error\DebugExceptionHandler). Since flash messages are integrated in the Backend template, PHP messages will not destroy the Backend layout.
  • Displays errors as TsLog messages in the adminpanel.
  • Logs error messages to \TYPO3\CMS\Core\Utility\GeneralUtility::syslog() which is able to write error messages to a file, to the web server’s error_log, the system’s log and it can send you errors and exceptions in an email. \TYPO3\CMS\Core\Utility\GeneralUtility::syslog() offers a hook and can be extended by user-defined logging methods.
  • Logs error messages to \TYPO3\CMS\Core\Utility\GeneralUtility::devLog() if $TYPO3_CONF_VARS[SYS][enable_errorDLOG] is enabled (depending on the devlog extension used, this might require an existing DB connection).
  • Logs error messages to the sys_log table. Logged errors are displayed in the belog extension (Admin Tools > Log) (works only if there is an existing DB connection).
