如何彻底关闭WordPress自动更新和后台更新检查 | Lenix Blog

WordPress 的后台更新检测和自动更新功能，由于WordPress更新服务器在国外，而国内的网络由于总总原因总是无法顺畅得连接上WordPress的更新服务器，所以一直卡在那里，造成WordPress后台非常慢！

在当前主题的functions.php文件添加如下代码，就可以彻底关闭 WordPress 自动更新和后台更新检查，这样更新的时候，就要手动来更新了

注：编辑之前记得备份哦

add_filter('automatic_updater_disabled', '__return_true');
// 关闭更新检查定时作业
remove_action('init', 'wp_schedule_update_checks');

后台管理界面修改

WordPress后台很多模块有时并不需要，使用下面的代码可以将它们屏蔽掉。
根据需要，将下面代码添加到当前主题functions.php模板文件中：

屏蔽左侧菜单

function remove_menus() {
global $menu;
$restricted = array(
__('Dashboard'),
__('Posts'),
__('Media'),
__('Links'),
__('Pages'),
__('Appearance'),
__('Tools'),
__('Users'),
__('Settings'),
__('Comments'),
__('Plugins')
end ($menu);
while (prev($menu)){
$value = explode(' ',$menu[key($menu)][0]);
if(strpos($value[0], '<') === FALSE) {
if(in_array($value[0] != NULL ? $value[0]:"" , $restricted)){
unset($menu[key($menu)]);
}else {
$value2 = explode('<', $value[0]);
if(in_array($value2[0] != NULL ? $value2[0]:"" , $restricted)){
unset($menu[key($menu)]);
if (is_admin()){
// 屏蔽左侧菜单
add_action('admin_menu', 'remove_menus');
function remove_menus() {
global $menu;
$restricted = array(
__('Dashboard'),
__('Posts'),
__('Media'),
__('Links'),
__('Pages'),
__('Appearance'),
__('Tools'),
__('Users'),
__('Settings'),
__('Comments'),
__('Plugins')
);
end ($menu);
while (prev($menu)){
$value = explode(' ',$menu[key($menu)][0]);
if(strpos($value[0], '<') === FALSE) {
if(in_array($value[0] != NULL ? $value[0]:"" , $restricted)){
unset($menu[key($menu)]);
}
}else {
$value2 = explode('<', $value[0]);
if(in_array($value2[0] != NULL ? $value2[0]:"" , $restricted)){
unset($menu[key($menu)]);
}
}
}
}
if (is_admin()){
// 屏蔽左侧菜单
add_action('admin_menu', 'remove_menus');
}

删除子菜单

function remove_submenu() {
// 删除”设置”下面的子菜单”隐私”
remove_submenu_page('options-general.php', 'options-privacy.php');
// 删除”外观”下面的子菜单”编辑”
remove_submenu_page('themes.php', 'theme-editor.php');
if (is_admin()){
//删除子菜单
add_action('admin_init','remove_submenu');
function remove_submenu() {
// 删除”设置”下面的子菜单”隐私”
remove_submenu_page('options-general.php', 'options-privacy.php');
// 删除”外观”下面的子菜单”编辑”
remove_submenu_page('themes.php', 'theme-editor.php');
}
if (is_admin()){
//删除子菜单
add_action('admin_init','remove_submenu');
}

屏蔽后台更新模块

function wp_hide_nag() {
remove_action( 'admin_notices', 'update_nag', 3 );

function wpse50723_remove_help($old_help, $screen_id, $screen){
$screen->remove_help_tabs();
return $old_help;
function remove_screen_options(){ return false;}
add_filter('screen_options_show_screen', 'remove_screen_options');
add_filter( 'contextual_help', 'wpse50723_remove_help', 999, 3 );
