在插件停用时编辑.htaccess

Question

1. 我试图在插件激活期间在.htaccess中添加重写规则。如何在插件停用时编辑/回滚.htaccess中的重写规则？

   function add_to_htaccess( $rules ) {
       $content = <<<EOD
       \nAddOutputFilterByType DEFLATE text/plain
       AddOutputFilterByType DEFLATE text/html
       AddOutputFilterByType DEFLATE text/xml
       AddOutputFilterByType DEFLATE text/css
       AddOutputFilterByType DEFLATE application/xml
       AddOutputFilterByType DEFLATE application/xhtml+xml
       AddOutputFilterByType DEFLATE application/rss+xml
       AddOutputFilterByType DEFLATE application/javascript
       AddOutputFilterByType DEFLATE application/x-javascript
       AddOutputFilterByType DEFLATE application/x-httpd-php
       AddOutputFilterByType DEFLATE application/x-httpd-fastphp
       AddOutputFilterByType DEFLATE image/svg+xml
       SetOutputFilter DEFLATE\n\n
       EOD;
       return $content . $rules;
   }
   add_filter('mod_rewrite_rules', 'add_to_htaccess');
   
   function myplugin_enable_flush_rules() {
       global $wp_rewrite;
       $wp_rewrite->flush_rules();
   }
   register_activation_hook( __FILE__, 'myplugin_enable_flush_rules' );
   

2. 上述函数在默认WordPress规则中添加了重写规则，位于# BEGIN WordPress和# END WordPress之间。我该怎么做才能单独添加（在.htaccess的底部？）

Answer 1

我已经设法自己做了。以下是我添加的功能。

function myplugin_deactivate() {
    // This will remove the rewrite rules
    remove_filter('mod_rewrite_rules', 'add_to_htaccess');

    global $wp_rewrite;

    // Flush the rewrite rules
    $wp_rewrite->flush_rules();
}
register_deactivation_hook( __FILE__, 'myplugin_deactivate' );
