And the error levels can be found on the page of watchdog_severity_levels. For an error, you'll most probably use WATCHDOG_ERROR, or maybe even something more "critical", depending on the kind of error. share|improve this answer answered Nov 10 '09 at 5:45 Pascal MARTIN 270k41501564 3 $type is generally the name of the module you are developing. –anyulled Feb 23 '15 at 22:21 add a comment| up vote 6 down vote 1) Indeed, watchdog is a standard way to record own PHP errors. 2) Alternatively, if you need to immediately see error messages while debugging your Drupal pages, you may want to see them logged/printed right at the related page - in FireBug console. Sometimes is this very convenient when you can see page-related just-in-time logs. This requires - Devel module, Firebug extension to FireFox and possibly Firephp. You can use the dfb() function to write log messages directly to the general Firebug console. dfb($input, $label = NULL) If you want to keep your Drupal-related log messages out of the normal Firebug console, you can write messages to the Drupal for Firebug log with the firep() function: firep($item, $optional_title) share|improve this answer edited May 30 '

As a result, there are two places to monitor for PHP errors (with the watchdog UI not well suited to cater for any large number of notices). Is it possible to prevent this behavior and have ALL php errors be logged to the error_log defined in the php config? 7 watchdog share|improve this question edited Nov 28 '15 at 17:19 kiamlaluno♦ 66.5k897192 http://drupal.stackexchange.com/questions/97434/write-all-php-errors-warnings-and-notices-to-error-log asked Dec 16 '13 at 17:47 cjoy 469318 If the syslog module (in core) is working as expected, you should be able to disable the dblog module (also core). That will remove the watchdog UI page as well. –Neograph734 Dec 16 '13 at 21:55 Thank you, but my question is neither aimed at disabling watchdog completely nor using syslog. –cjoy Dec 17 '13 at 10:43 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote accepted For that, you will need to implement the hook_watchdog to make calls to the error_log() function. You could as example one of the places where is implemented, that is the syslog_watchdog. Instead of use the openlog() and syslog() function, you will use the error_log(). share|improve this answer answered Dec 16 '13 at 18:27 gerzenstl 658215 While this does not prevent PHP warnings and notices from being passed to dblog/watchdog, it makes possible the passing of php related entries to the default error_log. Thanks! –cjoy Dec 17 '13 at 13:32 add a comment| up vote 1 down vote Rudimentary code example for the solution provided by @gerzenstl /** * Implements hook_watchdog() */ function MYMODULE_watchdog(array $log_entry) { if($log_entry['type'] == 'php') { $output = format_string($log_entry['message'], $log_entry['variables']); $output = strip_tags($output); error_log($output); } } share|improve this answer answered Dec 17 '13 at 13:38 cjoy 469318 add a c

Last updated: http://alvinalexander.com/drupal/drupal-how-log-errors-messages-watchdog June 3 2016 Drupal FAQ: How do I log Drupal errors (error http://www.w3schools.com/php/func_error_log.asp messages)? The standard way to log Drupal error messages is with the watchdog function. The watchdog function logs your messages to your database, where you can then view them from your Drupal Reports URL. In Drupal 6 and Drupal 7 the watchdog function has this signature: watchdog($type, $message, $variables = error log array(), $severity = WATCHDOG_NOTICE, $link = NULL) The watchdog function parameters are described in the link above, and are repeated here for your convenience: $message The message to store in the log. See t() for documentation on how $message and $variables interact. Keep $message translatable by not concatenating dynamic values into it! $variables Array of variables to replace in the message on drupal write to display or NULL if message is already translated or not possible to translate. $severity The severity of the message, as per RFC 3164. Possible values are WATCHDOG_ERROR, WATCHDOG_WARNING, etc. $link A link to associate with the message. Here's a link to more information on the watchdog severity levels. Drupal watchdog examples Given the default values shown in the function definition above, in a simple case you can call the Drupal watchdog function like this: watchdog('my_module', 'my error message'); Here's a watchdog logging example from the Drupal email module: watchdog('mail', 'Email injection exploit attempted in email form subject: ' . check_plain($form_state['values']['subject']), WATCHDOG_NOTICE); Here's a simpler watchdog function call from the Views module: watchdog('views_logging', '
' . $output . ''); Finally, here's a watchdog function call from the Workflow module: watchdog('workflow', 'Attempt to go to nonexistent transition (from %old to %new)', array('%old' => $old_sid, '%new' => $sid, WATCHDOG_ERROR)); Logging Drupal errors to syslog On a related note, you can log Drupal error messages to syslog on Linux systems using the Drupal syslog module. There's more information on that in this Drupal syslog documentation page. drupal watchdog warnings sys
