关于插件的更多概述WordPress-Multisite-Enhancements 可能会有帮助。这将添加一列以查看网络每个站点中的激活情况。屏幕截图将显示结果。

许多插件只有在您删除后端UI上的插件时才会卸载数据库中的数据。仅删除文件夹会删除插件，但通常不会删除数据库条目。

我完成了“浏览所有博客”的计划。我的代码很粗糙，但很有效。

首先，我从Plugin Activation Status 插件。因为该插件只列出哪个插件处于活动状态，在哪里可以方便地获取功能。

我的函数版本在范围上有所缩减，只返回一个以blog ID为键的关联数组和一个以插件基名称为值的数组。网络范围的插件包含在“网络”键下。

// Note: Since the source plugin is licensed under GPLv2 or later, so is this snippet.
function parse_plugins() {
global $wpdb;

$blogs = $wpdb->get_col( "SELECT blog_id FROM {$wpdb->blogs} ORDER BY blog_id" );
$network_plugins = $wpdb->get_results( $wpdb->prepare( "SELECT site_id, meta_value FROM {$wpdb->sitemeta} WHERE meta_key=%s", \'active_sitewide_plugins\' ) );

$active = array(\'network\' => array());

foreach ( $network_plugins as $k => $val ) {

    $v = maybe_unserialize( $val->meta_value );

    if ( ! is_array( $v ) )
        continue;
    if ( count( v ) <= 0 )
        continue;

    $tmp = array_values( $v );
    /**
        * Some records are stored with the plugin name as the key & the timestamp 
        *       of activation as the value; others are stored with just the plugin 
        *       name as the value, with numeric keys
        */
    $v = is_numeric( $tmp[0] ) ? array_keys( $v ) : array_values( $v );
    $active[\'network\'] = array_merge( $active[\'network\'], $v );
}

/**
    * Retrieve all of the plugins active on individual sites
    */
foreach ( $blogs as $b ) {
    $wpdb->set_blog_id( $b );

    $plugins = maybe_unserialize( $wpdb->get_var( $wpdb->prepare( "SELECT option_value FROM {$wpdb->options} WHERE option_name=%s", \'active_plugins\' ) ) );
    if ( ! is_array( $plugins ) )
        continue;
    $tmp = array_values( $plugins );
    if ( count( $tmp ) <= 0 )
        continue;
    /**
        * Some records are stored with the plugin name as the key & the timestamp 
        *       of activate as the value; others are stored with just the plugin 
        *       name as the value, with numeric keys
        */
    $plugins = is_numeric( $tmp[0] ) ? array_keys( $plugins ) : array_values( $plugins );
    $active[$b] = $plugins;
}

return $active;

现在我们知道了哪个插件处于活动状态，我们可以在网络中漫游并停用它们。

function deactivate_all_the_plugins()
{
    $active_plugins = parse_plugins();

    // Add the basenames of all unwanted plugins here
    $target_plugins = array(
    \'hello.php\',
    \'akismet/akismet.php\',
    \'some-other-plugin/other_plugin.php\'
    );

    foreach ($active_plugins as $blog_id => $blog_plugins) {
        $plugins = array_intersect($target_plugins, $blog_plugins);

        if (!empty($plugins)) {
            if ($blog_id == \'network\') {
                deactivate_plugins($plugins, false, true);
            }
            else {
                switch_to_blog($blog_id);
                deactivate_plugins($plugins, false, false);
                restore_current_blog();
            }
        }

        echo \'<h1>\'.$blog_id.\'</h1>\'; var_dump($plugins);
    }
}
