Code Snippets


Code Snippets is an easy, clean and simple way to run code snippets on your site. It removes the need to add custom snippets to your theme’s functions.php file.

A snippet is a small chunk of PHP code that you can use to extend the functionality of a WordPress-powered website; essentially a mini-plugin with less load on your site.
Most snippet-hosting sites tell you to add snippet code to your active theme’s functions.php file, which can get rather long and messy after a while.
Code Snippets changes that by providing a GUI interface for adding snippets and actually running them on your site just as if they were in your theme’s functions.php file.

Code Snippets provides graphical interface, similar to the Plugins menu, for managing snippets. Snippets can be activated and deactivated, just like plugins. The snippet editor includes fields for a name, a visual editor-enabled description, tags to allow you to categorize snippets, and a full-featured code editor. Snippets can be exported for transfer to another site, either in JSON for later importing by the Code Snippets plugin, or in PHP for creating your own plugin or theme.

How can I recover my site if it is crashed by a buggy snippet?

You can recover your site by enabling the Code Snippets safe mode feature. Instructions for how to turn it on are available here:

Will I lose my snippets if I change the theme or upgrade WordPress?

いいえ、スニペットはテーマとは無関係に WordPress データベースに保存され、WordPress のアップグレードの影響を受けません。

Can the plugin be completely uninstalled?

If you enable the ‘Complete Uninstall’ option on the plugin settings page, Code Snippets will clean up all of its data when deleted through the WordPress ‘Plugins’ menu. This includes all stored snippets. If you would like to preserve the snippets, ensure they are exported first.

作成したスニペットを別の WordPress サイトにコピーできますか ?

はい! 「スニペットの管理」ページのスニペット名の下にあるリンクを使って単一のスニペットを個別にエクスポートしたり、「一括アクション」機能を使って複数のスニペットを一括してエクスポートすることができます。スニペットは、「スニペットのインポート」ページでエクスポートしたファイルをアップロードすることで、後でインポートすることができます。

Can I export my snippets to PHP for a site where I’m not using the Code Snippets plugin?

はい。エクスポートしたいスニペットの横にあるチェックボックスをクリックし、「一括操作」メニューから「PHP にエクスポート」を選択して「適用」をクリックします。生成されたPHP ファイルには、エクスポートされたスニペットのコードのほか、名前と説明がコメントとして含まれます。

Can I run network-wide snippets on a multisite installation?

ネットワークダッシュボードから Code Snippets をネットワーク起動することで、マルチサイトネットワーク全体でスニペットを実行することができます。また、メインサイトだけで Code Snippets を有効にして、他のお好きなサイトで個別に有効にすることもできます。

WordPress データベースのどこにスニペットが保管されているのでしょうか?

スニペットは WordPress データベースの wp_snippets テーブルに格納されます。テーブル名は、テーブルのプレフィックスの設定によって異なる場合があります。

Where can I go for help or suggest new features?

Code Snippets のヘルプを取得したり、バグやエラーを報告したり、WordPress サポート フォーラムまたはGitHubで新機能や改善点を提案したりできます

How can I help contribute to the development of the Code Snippets plugin?

Good, no problems, But it is irritating, that when a syntax error is created (by myself) that all changes are lost. (So before every save I copy the content of the snippet first)
Users of this plugin already know how efficient and remarkable this one is. For those new to this, all I can say from experience of using Code Snippets on several of m websites - THANK YOU, team Code Snippets! Not having this plugin will show any Wordpress admin clearly the value it brings.
The worst thing about the plugin is when you would like press <ctrl + s> and the finger presses <ctrl + w>.
Never had any problems with it. It always did what I needed. Then one day I updated the plugin and it had a problem. I messaged the developer in the support forum on and he released a patch right away. Things have bugs from time to time so I decided to leave this 5 star review because of how quickly the developer released a patch for the bug I experienced and because I have this plugin installed on almost every site I use. It is my go to for adding snippets of code without having to change the functions.php
