代码介绍

下边代码是很基础的功能，我正好看到子比很多用户需要这个功能，然后我也正好需要我就随便写了个，这个主要功能是比如自己的网站想要维护一天，并且自己管理员账号还需要可以访问，然后还想要对网站没任何影响，这样你就需要了下边的代码，下边的代码也就是开启了定期维护2023-08-20 23:00:00这个时间是结束维护时间代码的意思也就是说如果当前时间大于结束维护时间则不在执行往下的代码，如果小于则执行下边的维护代码，维护代码我使用了 current_user_can( ‘manage_options’ ) 这个是判断用户身份是否为管理员，我在这个之前加了个叹号，作用就是如果不是管理员则执行维护模式，我使用了wordpress自带的wp_die函数，分别传递了三个参数分别为
1.提醒内容

2.网页的title标题

3.网页的相应状态码

详细代码

function zhutw_maintenance_mode() {
    $current_time = current_time( 'timestamp' );
    $target_time = strtotime( '2023-08-20 23:00:00' );

    if ( $current_time > $target_time ) { 
        return;
    }

    if ( ! current_user_can( 'manage_options' ) ) {

使用方法

可以自主选择是加在子比主题下的functions.php也可以自己创建func.php文件然后添加进去即可。最后在悄悄地告诉你这个方法不仅仅适用于子比主题模板哦。
