geeklog から WordPress への記事移動プログラム

phpblock_geeklog2mt.phpを改造してphpblock_geeklog2wp.phpを作ってみた。基本phpblock_geeklog2mt.phpと同じで、出力フォーマットをWordPress用にした。

概要

スポンサードリンク

簡単な使い方

  1. geeklog/customにphpblock_geeklog2wp.php ファイル設置。
  2. lib-custom.phpに require_once( ‘custom/phpblock_geeklog2wp.php’ ); を追加。
  3. geeklogの管理画面からエクスポートする話題を選択。
  4. geeklog/data/ の出力されたファイルをローカルに保存。
  5. WordPressの管理画面からWordPress形式でのインポートを選択し、上記ファイルを選択する。
  6. 環境によってはWordPress側の受け入れが中断されることがあるので、その時はアップロードから再度行う。
  7. 記事数、メディア数を確認して問題なければ完了。
