PHP部分

使用方法很简单，将下面的代码添加到WordPress主题的“functions.php”文件中即可。

function io_login_header(){
echo '<div class="login-container">
<div class="login-body">
<div class="login-img shadow-lg position-relative flex-fill">
<div class="img-bg position-absolute">
<div class="login-info">
<h2>'. get_bloginfo('name') .'</h1>
<p>'. get_bloginfo('description') .'</p>
</div>
</div>
</div>';
}
function io_login_footer(){
echo '</div><!--login-body END-->
</div><!--login-container END-->
<div class="footer-copyright position-absolute">
<span>Copyright © <a href="'. esc_url(home_url()) .'" class="text-white-50" title="'. get_bloginfo('name') .'" rel="home">'. get_bloginfo('name') .'</a></span>
</div>';
}
add_action('<a href="https://www.xhybk.com/tag/login" title="更多关于 login 的文章" target="_blank">login</a>_header', 'io_login_header');
add_action('login_footer', 'io_login_footer');
//登录页面的LOGO链接为首页链接
add_filter('login_headerurl',function() {return esc_url(home_url());});
