drupal/includes/bootstrap.inc, line 808
Description
Log a system message.
@see watchdog_severity_levels()
Parameters
$type The category to which this message belongs.
$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 display or NULL if message is already translated or not possible to translate.
$severity The severity of the message, as per RFC 3164
$link A link to associate with the message.
Code
function watchdog($type, $message, $variables = array(), $severity = WATCHDOG_NOTICE, $link = NULL) {
global $user, $base_root;
static $in_error_state = FALSE;
// It is possible that the error handling will itself trigger an error. In that case, we could
// end up in an infinite loop. To avoid that, we implement a simple static semaphore.
if (!$in_error_state) {
$in_error_state = TRUE;
// Prepare the fields to be logged
$log_message = array(
'type' => $type,
'message' => $message,
'variables' => $variables,
'severity' => $severity,
'link' => $link,
'user' => $user,
'request_uri' => $base_root . request_uri(),
'referer' => referer_uri(),
'ip' => ip_address(),
'timestamp' => time(),
);
// Call the logging hooks to log/process the message
foreach (module_implements('watchdog', TRUE) as $module) {
module_invoke($module, 'watchdog', $log_message);
