Wordpress で管理画面にカテゴリIDを表示

Posted at

検索してみたら『URLのパラメータを調べろ』ばっかりだったのでメモ。

functions.php に

<?php
function add_category_columns($columns)
{
	$index = 1; // 追加位置

	return array_merge(
		array_slice($columns, 0, $index),
		array('id' => 'ID'),
		array_slice($columns, $index)
	);
}
add_filter('manage_edit-category_columns', 'add_category_columns');

function add_category_custom_fields($deprecated, $column_name, $term_id)
{
	if ($column_name == 'id') {
		echo $term_id;
	}
}
add_action('manage_category_custom_column', 'add_category_custom_fields', 10, 3);

て書いておくと編集画面がこんな感じになります。

他の場所に出す時はフィルタ/アクション名を調べて追記すれば良し。
