wordpress判断前台是否显示登陆、退出、注册按钮

在index.php中加入以下代码即可

<?php if (!(current_user_can('level_0'))){ ?>  
<span class="register"><a href="<?php%20echo%20get_option('home');%20?>/wp-login.php?action=register">注册</a></span>
<span class="login"><a href="<?php%20echo%20get_option('home');%20?>/wp-login.php">登录</a></span>
	<?php } else { ?>	
<span class="register"> <a href="<?php%20echo%20home_url().'/wp-admin/'?>">管理</a></span>
<span class="login"><a href="<?php%20echo%20wp_logout_url(%20get_bloginfo('url')%20);%20?>">登出</a></span>
<?php }?>
