Analyze the registration and login mechanism of ECMall_PHP tutorial

ecmall registration process index.php?app=member&act=register.

First of all, app is member and act is register method.

index.php. Started through ecmall's startup method, which mainly includes eccore/ecmall.php. The startup method includes eccore/controller/app.base.php and eccore/model/model.base.php basic classes, through

$app = isset($_REQUEST['app']) ? trim($_REQUEST['app']) : $default_app;
$act = isset($_REQUEST['act']) ? trim($_REQUEST['act']) : $default_act; 

to get app and act.

If it is registration, act=member then

$app_class_name = ucfirst($app) . 'App';
/* 实例化控制器 */
$app = new $app_class_name();

Here $app = new MemberApp, calling the register method in the MemberApp class. In the register method, get the registration information. Through the ms method in global.lib.php.

include(ROOT_PATH . '/includes/passport.base.php');
include(ROOT_PATH . '/includes/passports/' . MEMBER_TYPE . '.passport.php'.regissword.php

And the following program in the ms() function in register

include(ROOT_PATH . '/includes/passports/' . MEMBER_TYPE . '.passport.php');
$class_name  = ucfirst(MEMBER_TYPE) . 'Passport';
$ms = new $class_name();

Contains the DefaultPassport class in default.passport.php, and it inherits BasePassport, which has a few lines of code

$user_class_name = ucfirst($this->_name) . 'PassportUser';
$this->user = new $user_class_name();

So this is where $this -> user in the program comes from.

$user_class_name is actually the DefaultPassportUser class in includes/passports/default.passport.php. And he extends BasePassportUser, and he calls the _local_add() method in BasePassportUser. The _local_add() method calls the The initialization data in member.model.php is processed in the database through the function add($data, $compatible = false) method under the BaseModel class in eccore/model/model.base.php. This completes the registration function.

    /**
     *  添加一条记录
     *
     *  @author Garbin
     *  @param  array $data
     *  @return mixed
     */
    function add($data, $compatible = false)
    {
        if (empty($data) || !$this->dataEnough($data))
        {
            return false;
        }
        $data = $this->_valid($data);
        if (!$data)
        {
            $this->_error('no_valid_data');
            return false;
        }
        $insert_info = $this->_getInsertInfo($data);
        $mode = $compatible ? 'REPLACE' : 'INSERT';
        $this->db->query("{$mode} INTO {$this->table}{$insert_info['fields']} VALUES{$insert_info['values']}");
        $insert_id = $this->db->insert_id();
        if ($insert_id)
        {
            if ($insert_info['length'] > 1)
            {
                for ($i = $insert_id; $i < $insert_id + $insert_info['length']; $i++)
                {
                    $id[] = $i;
                }
            }
            else
            {
                /* 添加单条记录 */
                $id = $insert_id;
            }
        }
        return $id;
    }

Login mechanism

The process of logging in to the ecmall e-commerce system is actually very complicated. First, he calls the login page by calling malldefaultlogin.html. The calling program is implemented by calling the login method of appfrontend.base.php.

The if (!IS_POST) program represents the display of the login page, which is processed by calling $this->display('login.html'). The login.html page of ecmall mainly has the following variables to be passed. The three variables user_name, password, and captcha are used for login verification. $user_name = trim($_POST['user_name']) and $password = $_POST['password'] are mainly used to accept usernames and passwords. Login verification is performed by connecting to the login center $ms =& ms() to call $ms->user->auth($user_name, $password).

The function &ms() in the file includes/global.lib.php is used to connect to the login center. include(ROOT_PATH . '/includes/passports/' . MEMBER_TYPE . '.passport.php'); $class_name = ucfirst(MEMBER_TYPE) . 'Passport';$ms = new $class_name();Here is to declare the login object .
