如何修复XAMPP错误“MySQL意外关闭”
restore_current_blog ( No parameters )
restore_current_blog: 这是一个WordPress的函数,在切换到一个多站点网络中的不同站点后恢复当前站点的上下文: 当用户切换到网络中的不同站点时,新站点的上下文被设置,随后的任何查询或操作都在新站点上进行。要切换回原来的站点,需要调用 restore_current_blog 来恢复原来站点的上下文。
在调用switch_to_blog()之后,恢复当前的博客。
function restore_current_blog() { global $wpdb; if ( empty( $GLOBALS['_wp_switched_stack'] ) ) { return false; } $new_blog_id = array_pop( $GLOBALS['_wp_switched_stack'] ); $prev_blog_id = get_current_blog_id(); if ( $new_blog_id == $prev_blog_id ) { /** This filter is documented in wp-includes/ms-blogs.php */ do_action( 'switch_blog', $new_blog_id, $prev_blog_id, 'restore' ); // If we still have items in the switched stack, consider ourselves still 'switched'. $GLOBALS['switched'] = ! empty( $GLOBALS['_wp_switched_stack'] ); return true; } $wpdb->set_blog_id( $new_blog_id ); $GLOBALS['blog_id'] = $new_blog_id; $GLOBALS['table_prefix'] = $wpdb->get_blog_prefix(); if ( function_exists( 'wp_cache_switch_to_blog' ) ) { wp_cache_switch_to_blog( $new_blog_id ); } else { global $wp_object_cache; if ( is_object( $wp_object_cache ) && isset( $wp_object_cache->global_groups ) ) { $global_groups = $wp_object_cache->global_groups; } else { $global_groups = false; } wp_cache_init(); if ( function_exists( 'wp_cache_add_global_groups' ) ) { if ( is_array( $global_groups ) ) { wp_cache_add_global_groups( $global_groups ); } else { wp_cache_add_global_groups( array( 'blog-details', 'blog-id-cache', 'blog-lookup', 'blog_meta', 'global-posts', 'networks', 'sites', 'site-details', 'site-options', 'site-transient', 'rss', 'users', 'useremail', 'userlogins', 'usermeta', 'user_meta', 'userslugs', ) ); } wp_cache_add_non_persistent_groups( array( 'counts', 'plugins' ) ); } } /** This filter is documented in wp-includes/ms-blogs.php */ do_action( 'switch_blog', $new_blog_id, $prev_blog_id, 'restore' ); // If we still have items in the switched stack, consider ourselves still 'switched'. $GLOBALS['switched'] = ! empty( $GLOBALS['_wp_switched_stack'] ); return true; }
