Prestashop - how do I write to a log file?

问题

What php code should I use in a Prestashop module to write to a log file? I have used

Logger::addLog("something",1);

but it does not work.

回答1:

You can also store the log in file using below code.

$logger = new FileLogger(0); //0 == debug level, logDebug() won’t work without this.
$logger->setFilename(_PS_ROOT_DIR_.”/log/debug.log”);
$logger->logDebug(“message 1″);
$logger->logDebug(“message 2″);

It will work!.

Thanks

回答2:

The log is saved in database in 'log' table (with your current prefix);

Another alternative is to use PHP's

file_put_contents(_PS_ROOT_DIR_ . '/path/to/logfile',
                  $data . "\n",
                  FILE_APPEND);
