Here is some of the documentation I created while implementing logging in Yii, it might be of your help:
========================= Configure xampp to send the emails from localhost code ==========================================
Changes for C:\xampp\php\php.ini file:
search for [mail function]:
[mail function]
SMTP=localhost to SMTP=smtp.gmail.com
smtp_port=587
sendmail_from=me#example.com to sendmail_from=your email address
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
mail.add_x_header=Off
mail.log = syslog
Changes for C:\xampp\sendmail\sendmail.ini:
search for [sendmail]:
smtp_server=smtp.gmail.com
smtp_port=587
smtp_ssl=auto
error_logfile=error.log
debug_logfile=debug.log
auth_username=same as "sendmail_from" in php.ini file
auth_password=generated password for the email account
force_sender= same as "auth_username" in this file
================================================ Restart Xampp Server =====================================================
=================================================== Add table in DB =======================================================
drop table if exists "log";
create table "log"
(
"id" number(20) NOT NULL PRIMARY KEY,
"level" integer,
"category" varchar(255),
"log_time" number,
"prefix" text,
"message" text,
key "idx_log_level" ("level"),
key "idx_log_category" ("category")
);
============================================ Configuration in Yii2 project ================================================
add in "components" array in app\config\console.php and app\config\web.php both files:
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
// send all mails to a file by default. You have to set
// 'useFileTransport' to false and configure a transport
// for the mailer to send real emails.
'useFileTransport' => false,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.gmail.com',
'username' => 'your email address (for testing on localhost use same as in ini files)',
'password' => 'generated password',
'port' => 587,
'encryption' => 'tls',
],
], //end of mailer
'log' => [
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning','info'],
],
[
'class' => 'yii\log\DbTarget',
'levels' => ['error', 'warning','info'],
],
[
'class' => 'yii\log\EmailTarget',
'mailer' => 'mailer',
'levels' => ['error', 'warning','info'],
//'categories' => ['yii\db\*'],
'message' => [
'from' => ['your email address(for testing on localhost use same as in ini files)'],
'to' => ['receiptent email address'],
],
],
], // end of targets
'flushInterval' => 1,
], //end of logs
//------------------------ web.php (log configuration setup) -------------------------//
//categories name would be later assgined to messages:
Yii::info($message, 'userNotification');
