Login Wordpress/Woocommerce登录/注册页面需要什么确切的代码

我正在使用wordpress和woocommerce创建一个小型电子商务网站，但我并不真正了解用户的登录/注册功能。我只希望访问该网站的用户能够单击主页上的链接，在那里他们可以注册和登录（可以选择重置密码），作为回报，这些客户详细信息将保存在用户数据中，以便wordpress管理员能够看到。这个的编码是什么？因为我似乎无法深入了解这些插件。

<?php 
  global $wpdb, $user_ID; 
    $firstname='';
    $lastname='';
    $username='';
    $email='';

    //if looged in rediret to home page
    if ( is_user_logged_in() ) { 
        wp_redirect( get_option('home') );// redirect to home page
        exit;
    }

    if(sanitize_text_field( $_POST['com_submit']) != ''){

        $firstname=sanitize_text_field( $_REQUEST['com_firstname'] );
        $lastname=sanitize_text_field( $_REQUEST['com_lastname']);
        $username = sanitize_text_field(  $_REQUEST['com_username'] );
        $email = sanitize_text_field(  $_REQUEST['com_email']  );
        $password = $wpdb->escape( sanitize_text_field(    $_REQUEST['com_password']));
        $status = wp_create_user($username,$password,$email);

        if (is_wp_error($status))  {
             $error_msg = __('Username or Email already registered. Please try another one.','twentyten'); 
        } 
        else{
            $user_id=$status;
            update_user_meta( $user_id,'first_name', $firstname);
            update_user_meta( $user_id,'last_name', $lastname);
