wordprss结账界面页面调整

1.去除重置密码邮箱找回，隐藏登录表单中的“忘记密码？”链接（登录界面以及登录失败界面）

 使用CSS隐藏，在WordPress后台，转到外观 > 自定义 > 额外CSS，然后添加以下代码

.woocommerce-form-login .lost_password {
    display: none;
}
a[href*="lost-password"] {
    display: none;
}

 2.用户名或邮箱登录 改成用户名登录(functions.php)

function force_username_login( $user, $username, $password ) {
    // Check if the login attempt is using an email
    if ( strpos( $username, '@' ) !== false ) {
        // If it's an email, reject the login attempt
        return new WP_Error( 'invalid_email', __( 'Invalid username.' ) );
    }
    return $user;
}
add_filter( 'authenticate', 'force_username_login', 10, 3 );

  3.用户结算页登录栏添加提示语(functions.php)

//忘记密码 改为 If you forget your password, please contact our customer service for assistance !
add_action('wp_footer', function() {
   ?>
    <script>
        (function() {
            var newText = document.createElement('p');
            newText.textContent = 'If you forget your password, please contact our customer service for assistance !';
            var loginForm = document.querySelector('.woocommerce-form-login');
            if (loginForm) {
                loginForm.appendChild(newText);
            }
        })();
    </script>
    <?php
});

 4.60分钟内限制错误次数不能超3次(functions.php)

// 60分钟内错误次数超3次
function limit_login_attempts($username) {
    $ip = $_SERVER['REMOTE_ADDR'];
    $transient_name = 'login_attempts_'. $ip;

    $attempts = get_transient($transient_name);

    if (false === $attempts) {
        $attempts = 1;
    } else {
        $attempts++;
    }

    set_transient($transient_name, $attempts, 60 * 60);

    if ($attempts >= 3) {
        wp_die('Too many login attempts have been made incorrectly. Please try again in one hour!');
    }
}
