自作ウィジェットでのWordPressのダッシュボード活用のアイデア

//①ダッシュボード表示時にsample_widgetを実行する
add_action('wp_dashboard_setup', 'sample_widget');

//②ダッシュボードへウィジェットを追加
function sample_widget() {
  wp_add_dashboard_widget('sample_widget', 'ウィジェットのサンプル', 'original_sample');
}

//③文字を表示するウィジェット
function original_sample() {
  echo '<p>これはサンプルです。</p>';
}

add_action('wp_dashboard_setup', 'original_dashboard_widgets');
function original_dashboard_widgets() {
  //①タイムゾーンの設定
  date_default_timezone_set('Asia/Tokyo');
  
  //②月初（1～3日以内）の場合にウィジェットを表示
  if (date('d') <= 3){
    wp_add_dashboard_widget('todo_widget', '月初対応', 'original_widget_reminder');
  }
}

function original_widget_reminder() {
  echo '<font color="#f00" size="6">対応忘れずに！</font><br>';
  echo '<ol><li>記事の追加</li><li>プログラムのパラメータ変更</li></ol>';
}

add_action('wp_dashboard_setup', 'original_dashboard_widgets');
function original_dashboard_widgets() {

  wp_add_dashboard_widget('elapsed_time_widget', '最終投稿からの経過時間', 'original_elapsed_time');
}

function original_elapsed_time() {
  $currentDate = date('Y-m-d h:m:s');

  //①経過日数と時間を算出（小数点以下切り捨て）
  $hours = floor((strtotime($currentDate) - strtotime(get_lastpostdate('blog'))) / (60 * 60));
  $days = floor($hours / 24);
  $hours = $hours - $days * 24;
  
  //②経過時間を表示
  if ($days > 1){
    echo '<font size="7">' . $days . '日と' . $hours. '時間</font><br>';
