给Typecho的Joe主题隐藏/显示侧边栏模块

上上上上期给大家写了个侧边栏公告，但有个 缺点 ，后台编辑公告栏无文字时不会隐藏，这样很不美观
Test

修复教程开始

1.将下列代码放入主题目录的`functions.php`文件里

 // 侧边栏公告开关
$NoticeSwitch = new Typecho_Widget_Helper_Form_Element_Select(
    'NoticeSwitch',
    array(
      'off' => '关闭（默认）',
      'on' => '开启'
    ),
    'off',
    '是否开启侧边栏公告模块 - PC',
    '介绍：用于控制是否显示公告'
  );
$NoticeSwitch->setAttribute('class', 'joe_content joe_other');
$form->addInput($NoticeSwitch->multiMode());

Test

2.再将下列代码放入主题目录的`aside.php`文件里

  <?php if ($this->options->NoticeSwitch === 'on') : ?>
  包裹住你要隐藏的侧边栏模块的代码区域
  <?php endif; ?>

Test

懒人专用 把下面代码替换 3个方框 里的代码即可

  <?php if ($this->options->NoticeSwitch === 'on') : ?>
    <section class="joe_aside__item hot">
      <div class="joe_aside__item-title">
