Twitterで過去記事を自動で呟くのをやってみた。凄く簡単「Tweetily」の使い方

WordPressの過去記事を自動ツイートを設定できるプラグイン

Twitterで過去記事を自動で呟く仕組みいいなぁ。。と。
で、そのやり方も@mk_mizuhoさんの自動ツイートで知った次第です。

PickUp!! ➔: [Å] WordPressプラグイン「Tweetily」を使って過去記事をランダムにツイートするようにしてみた！ http://t.co/ifLegllkCc

[Å] WordPressプラグイン「Tweetily」を使って
過去記事をランダムにツイートするようにしてみた！

Tweetily

Tweetilyをまずダウンロード。直接「プラグインの新規追加」でもOK
で、有効化したら注意点。あかめさんのブログにもあるけど

日本語未対応！

なので、ちょっとコアファイルの修正が必要です。

日本語に対応する修正方法

①プラグイン編集から②で「Tweetily」を選択して「tweetily-tweet-wordpress-posts-automatically/top-core.php」をクリック。

で、これを変更するコードがあかめさんの記事に書いてあり、

古いかもしれないから気をつけろよ！

と書いてあるのを全開で無視してバックアップを取らず盲目的にコピーペースト！
⇒「ファイルを保存」！

エラー！！！！！

いう事は聞かないとダメですね。気を取り直して、再インストール。
