User Login section in Yii2

First: Use commands in your project

./yii Migrate/create Create_users_table

Generate the corresponding file to create the table in the Migrations directory in the project

<?php
Use Yii\db\schema;
Use yii\db\migration;
Use Yii\db\mysql;

Class M150225_074041_create_users_table extends migration
{
Public function up ()
{
$tableOptions = null;
if ($this->db->drivername== "MySQL") {
$tableOptions = "CHARACTER SET UTF8 COLLATE utf8_unicode_ci engine=innodb";
}
$this->createtable ("User", [
' ID ' =>schema::type_pk,
' username ' =>schema::type_string. " Not NULL ",
' Auth_key ' =>schema::type_string. " (+) Not NULL ",
' Display_name ' =>schema::type_string. " () Not NULL ",
"Password_hash" =>schema::type_string. " Not NULL ",
"Password_reset_token" =>schema::type_string,
"Email" =>schema::type_string,
"Role" =>schema::type_smallint. " Not NULL DEFAULT 10 ",
"Status" =>schema::type_smallint. " Not NULL DEFAULT 10 ",
"Created_at" =>schema::type_integer. " Not NULL ",
"Updated_at" =>schema::type_integer. " Not NULL ",
], $tableOptions);


}


Public function Down ()
{

}
}

Then run the command:./yii Migrate

The corresponding user table is generated in the database when the command is finished running.

The content in models/user.php is as follows:

<?php


namespace App\models;
