Class SS_Log

Wrapper class for a logging handler like Zend_Log which takes a message (or a map of context variables) and sends it to one or more Zend_Log_Writer_Abstract subclasses for output.

These priorities are currently supported: - SS_Log::ERR - SS_Log::WARN - SS_Log::NOTICE

You can add an error writer by calling SS_Log::add_writer()

Example usage of logging errors by email notification:

SS_Log::add_writer(new SS_LogEmailWriter('my@email.com'), SS_Log::ERR);

Example usage of logging errors by file:

SS_Log::add_writer(new SS_LogFileWriter('/var/log/silverstripe/errors.log'), SS_Log::ERR);

Example usage of logging at warnings and errors by setting the priority to '<=':

SS_Log::add_writer(new SS_LogEmailWriter('my@email.com'), SS_Log::WARN, '<=');

Each writer object can be assigned a formatter. The formatter is responsible for formatting the message before giving it to the writer. SS_LogErrorEmailFormatter is such an example that formats errors into HTML for human readability in an email client.

Formatters are added to writers like this:

$logEmailWriter = new SS_LogEmailWriter('my@email.com');
$myEmailFormatter = new MyLogEmailFormatter();
$logEmailWriter->setFormatter($myEmailFormatter);
