WPBeginnerでは、WordPressサイトの<header>セクションや<footer>セクションにコードを挿入する必要のあるチュートリアルを多く書いています。特にWordPressにはヘッダーやフッターにコードスニペットを追加するビルトインオプションが用意されていないため、これは大変な作業に感じられるかもしれません。
しかし、Google アナリティクス、Google Search Console、Facebook Pixelなどのウェブサービスと統合しようとすると、WordPressでヘッダーとフッターのコードを追加する必要がある。
WordPressのチュートリアルで、WordPressのヘッダーやフッターにカスタムCSSやJavaScriptコードを追加するよう求められることもあるでしょう。
幸いなことに、初心者には簡単な解決策がある。無料のWPCodeプラグインを使えば、WordPressテーマファイルを直接編集することなく、安全にコードを追加することができます。
この投稿では、WordPressでヘッダーとフッターのコードを簡単に追加する方法を紹介します。
WordPressのヘッダーとフッターのコードを追加する最良の方法
WordPressのヘッダーとフッターのコードを追加したい場合、3つの解決策が考えられます：
- 手動で、テーマのheader.phpとfooter.phpファイルを編集する。
- テーマにビルトインされたヘッダーとフッターのコード機能を使って
- WordPressプラグインの使用
最初の設定は、header.phpとfooter.phpファイルを直接手動で編集してヘッダーとフッターのコードを追加する必要があるため、初心者には優しくない。
この方法のもう一つの欠点は、テーマの更新をインストールするとコードが削除されてしまうことです。
2つ目のオプションは、テーマのビルトイン機能を使うことです。Elegant Themesや StudioPressのGenesis FrameworkのようなWordPressテーマには、WordPressのヘッダーやフッターにコードやスクリプトを素早く追加するためのビルトインオプションが用意されています。
ビルトイン機能のあるテーマを使っているのであれば、安全で簡単な解決策のように思える。しかし、テーマを変更すると、サイトに追加したコードスニペットがすべて消えてしまいます。これには、Google Search Consoleでのサイト検証、Googleアナリティクスによるサイト分析などが含まれる。
そのため、ユーザーには常に3つ目の設定、ヘッダーとフッターのプラグインを使うことをお勧めしています。この設定は、WordPressでヘッダーとフッターのコードを追加する最も簡単で安全な方法です。
読者からの多くのリクエストの後、私たちのチームはWPCodeプラグインを作りました。
WPCode（旧Insert Headers and Footers）は100％無料のコードスニペットプラグインです。WordPressのヘッダーとフッターに簡単にコードを追加することができます。
WPCodeプラグインを使用する利点は以下の通りです：
1.簡単、迅速、整理整頓：サイトのヘッダーとフッターに簡単かつ迅速にコードを追加できます。さらに、フッターとヘッダーのコードをすべて一箇所に保存できるため、整理整頓も簡単です。
2.エラーを防ぐ：スマートコードスニペット検証は、テーマファイルを手動で編集した場合に発生する可能性のあるエラーを防ぐのに役立ちます。
3.安心してテーマのアップグレードや変更ができる：プラグインはヘッダーとフッターのコードを区切りの良い場所に保存するので、コードが消えてしまう心配をすることなくテーマの更新や変更ができます。
ヘッダーとフッターのスクリプトの他に、WPCodeを使って、テーマファイルを編集することなく、カスタムのPHP、JavaScript、CSS、HTML、テキストコードスニペットを簡単に挿入することができます。
さらに、WPCodeには、最も便利なWordPressコードスニペットをすべて見つけることができるスニペットライブラリがビルトインされています。これにより、自動更新、REST API、XML-RPC、コメントなど、不要なWordPress機能をすばやく削除することができます。
注：プライベートクラウドスニペットライブラリ、変換ピクセル、スケジュールスニペット、コードリビジョンなどの高度な機能が必要な場合は、WPCode Proにアップグレードすることができます。

WordPressでヘッダーとフッターにコードを追加する
最初に行う必要があるのは、無料のWPCodeプラグインをインストールして有効化することです。詳しくは、WordPressプラグインのインストール方法のステップバイステップガイドをご覧ください。
プラグインを有効化したら、WordPressの管理画面からCode Snippets ” Header & Footerに移動します。その後、コードを追加できる「ヘッダー」ボックスが表示されます。
下にスクロールすると、「本文」と「フッター」ボックスも表示されます。
コードを3つのボックスのいずれかに貼り付けるだけです。設定が完了したら、「変更を保存」ボタンをクリックして設定を保存することをお忘れなく。
プラグインはWordPressサイトのそれぞれの場所にコードを自動的に読み込みます。
残したくないコードはいつでも編集して削除できる。
プラグインは常にインストーラして有効化しておく必要があります。プラグインを無効化すると、サイトへのすべてのカスタムコードの追加を停止します。
誤ってプラグインを無効化しても、コードはWordPressのデータベースに安全に保存されます。プラグインを再インストールまたは再アクティブ化するだけで、コードは再び外観に表示されるようになります。
注意：変更を保存した後、WordPressのキャッシュをクリアする必要があるかもしれません。そうすることで、あなたのサイトのフロントエンドにコードが正しく表示されます。
私たちは、初心者の多くがWPCodeプラグインを使用する最大の理由は、自分のサイトにGoogleアナリティクスを追加することであることがわかりました。そのために、私たちは実際に無料のMonsterInsightsプラグインを使用することをお勧めします。
MonsterInsightsはWordPressのための最高のGoogleアナリティクスプラグインです。数回のクリックでGoogleアナリティクスのトラッキングを適切に設定でき、WordPressダッシュボード内に役立つ統計情報を表示します。
ステップバイステップの手順については、WordPressにGoogleアナリティクスをインストールする方法のチュートリアルを参照してください。

my header and footer in not showing in particular page..how can i solve it
WPBeginner Support says
You would want to check with your specific theme’s support for the header not appearing on a specific page as it could be a page specific template causing you issues.

Thanks guys for your plugin! I used it to add FB Pixel to my site, but now I have a landing page and I need a different Pixel event (Lead) on the Thank You page after visitors confirm their details. Can I use the plugin to add the script to a specific page?
WPBeginner Support says
Not at the moment, for the time being, the plugin adds the code to all pages by default

You need to change your messaging/advertising regarding header/footer plug-in being free to install. It is not free unless you have purchased the Business plan for your page.
WPBeginner Support says
That would be because you are on WordPress.com, our tutorials are for WordPress.org sites. You can see the difference between the two here: https://www.wpbeginner.com/beginners-guide/self-hosted-wordpress-org-vs-free-wordpress-com-infograph/

Was wondering if PHP can be added in the header section. Like adding Yoast’s Breadcrumb code to the header so I don’t have to go into my theme files.
WPBeginner Support says
At the moment the plugin does not allow PHP code to be added.

Michael says
Thank you for your reply. Will, that ability be added in the future?
WPBeginner Support says
Currently, it is not planned but we will certainly look into it as a possibility if the need increases

I have another plugin it seems to work almost exactly the same way only it can be used on a single page or customized as to which pages the script is added.
I am trying the WpBeginner plugin just because I trust y’all.
Am I likely to run into problems having both added to my site?
Using yours for the whole site, and the other one for adding something only to the header or footer of an individual page?

Normally you shouldn’t but if you run into any conflicts you can reach out to the plugins supports

Hello,
I’m trying to update something in my footer section.
I have already downloaded and installed/ used this plug in previously and it is working currently. However, when I try to go edit it, when my cursor is hovering over settings…. no drop out menu appears to go to –>insert header and footer. It only takes me to my account setting page. Please help me because I need to update my mailing list options asap! Thank you!
WPBeginner Support says
If you go to your settings area, it should expand the other options for you to be able to see the Insert Headers and Footers menu item.

Thanks WPbeginer,
I tried saving the plugin when I added my google search console code, it redirected me to error 404.
What could be wrong?

That is quite odd, you may want to see if an error happened with your htaccess file when you saved: https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-posts-returning-404-error/
as the most common reason for 404 errors, if not you could use our troubleshooting article here: https://www.wpbeginner.com/beginners-guide/beginners-guide-to-troubleshooting-wordpress-errors-step-by-step/

Should i deactivate and delete the plugin after inserting the code?
Will the code be deleted as soon as the plugin is deactivated?

You would want to leave the plugin active, if you deactivate the plugin the code you’ve added will no longer be included.

Hello. I’ve been using this plugin for some time and find it invaluable.
However, I am about to update to WordPress 5 but on the download page, it says ‘Compatible up to 4.9.9’. This makes me wary – will it work with 5 and are there plans to update it? Thank you.
WPBeginner Support says
At the moment the plugin should work with the most recent version of WordPress but if you are concerned with the not tested number then you may want to take a look at our article: https://www.wpbeginner.com/opinion/should-you-install-plugins-not-tested-with-your-wordpress-version/

Hiya,
Thanks for recommending the Header and Footer plugin, and I have added code to just a single post only to prevent any issues.
I’ve noticed though, that my dropdown menu has stopped showing (just on the page with code). Do you have a Javascript fix, please?

Hope you can help.
Merry Xmas!!!!

Hey Ken,
Try uninstalling the plugin to see if that fixes your issue.

I have added this to my site. It reads it just fine, but prints the code across the top of my header bar EVERY time! Not sure how to fix this.

Plsss explian in details how to add more than one code in the headers space, cos i have already inserted ,google search console code with the pluggin how am i going to add the adsene code in the same headers section

How do I add a HTLM code in the header of my theme. I dont quite understand where it is. I use Xtheme and some people said to go to appearance and editor, but I dont have no editor.
I need to add the Gtag in the heard of my website for Google analytics and I dont want to use a plug in
mohamed ballouti says
I want to ask you about this plugin.
Can I put more than one code from different sites (eg Google Analytics code, Webmaster’s code, and Adsense ad code) Will the number of codes affects their performance because I see a difference in terms of visitors Google Analytics and WordPress analytics(WP Statistics)?
And the difference between placing the code in the header and in the footer?
Thank you sorry for bothering you
I hope you will respond quickly.
WPBeginner Support says
Hi Mohamed,
Yes you can add code from multiple sites like Analytics, Webmaster tools, and so on.
管理者
Samantha says
Like they asked, what is the difference between placing the code in the header or footer?
Thanks!
WPBeginner Support says
The code would be run sooner when placed in your header which makes it less likely to prevent loading due to a bad script when placed in the header
Gerardo says
Hi, is it possible use this plugin to add more scripts? For example i need to add the AdSense and PushCrew codes.
If possible, just copy the code one under the other?
Thanks

Hi Knut,
Here is the sample code that you can use to exclude header from any page using the page ID.

Riddhi says
Hey, is there anyway to check if the code has been inserted ? Can’t detect it in my site source code nor in the headers.php file. Is is possible for this plugin to not be working ?
WPBeginner Support says
Hi Riddhi,
Once you add the code and save your changes you will be able to see the code in your site’s source code. For header code you will find it between <head> and </head> tags. Footer code will be added before the </body> tag.

Debbie says
Is there a way to use this to add an image in the header that does not replace the existing header? In other words, I already have a logo there on the left, and a search bar with social media links on the right. The center is empty. I want to add an image widget which links to the source page of the image. I have the widget code ready to insert, but there is no HTML showing in the header.php file. I do not know PHP (i do know HTML quite well).
I added the widget to the footer, which was easy because in my theme there IS HTML (an HTML table) in the footer. But it is supposed to be at the top of the pages.
Ralph Machin says
Any idea when this plugin will be updated for WP 4.9.1? Looks like it’s only compatible up to 4.8.4

HI
How do i add the code to a single page header (not a post) so it appears only on that page?
WPBeginner Support says
Hey Rolland,
This plugin will add header and footer code to all pages and posts. If you want to add it to just a single page, then you will have to manually add your code to your theme and surround it with a conditional php tag. For example:
if (is_page( 22 )) { // your code goes here }1-click Use in WordPress
Don’t forget to replace 22 with your actual page ID.

Hi, I love the simplicity of this plugin. There is one annoying point however.
How can I disable the dashboard notice “Thank you for installing….” in a multisite set up.
I don’t need all my client sites seeing that notice.
A solution that doesn’t involve another plugin would be appreciated, preferably I can just remove an action or something.

Does that mean that I can’t disable the notice? (without hacking the plugin)
