WordPressの構文エラーを修正する方法

WordPressの構文エラーは、特にコーディングに慣れていない場合、圧倒されることがあります。

チュートリアルからコード・スニペットを追加するときに、この問題に遭遇するかもしれない。 小さなミスでもサイト全体を壊してしまう可能性があります。

構文エラー、予期しない…」という恐ろしいメッセージを見たことがあっても、慌てる必要はありません!私たちはこのエラーに何度も遭遇し、解決してきました。

このガイドでは、WordPressの構文エラーを修正する手順を説明します。最後には、サイトをスムーズに復旧させる方法がわかるでしょう。

How to Fix the Syntax Error in WordPress

WordPressの構文エラーとは何か?

WordPressの構文エラーは、追加したコードの構文が正しくない、つまりプログラミング言語のルールに従っていない場合に発生します。

この種のエラーは、コンマの抜け、余分な括弧、引用符の位置の間違いなど、単純なことで起こり得る。

では、なぜ構文エラーを気にする必要があるのか?

まず、サイト全体が停止してしまう可能性があります。美しく作られたサイトが表示される代わりに、訪問者はエラーメッセージで迎えられます。これはユーザーエクスペリエンスに影響を与えるだけでなく、サイトの評判や信頼性にも悪影響を及ぼしかねません。

さらに、構文エラーによってWordPressの管理エリアにアクセスできなくなることもあります。コーディングが苦手で、問題の解決方法がわからない場合は、特にストレスになります。

つまり、シンタックスエラーとは、コードの中にある小さいけれども重大なミスのことで、サイトに大きな影響を与える可能性があります。これらのエラーを素早く特定し、修正できることが、スムーズでプロフェッショナルなサイトを維持するための鍵となります。

エラーを避けるために正しい構文を使う

あなたのコードが最初から正しく書かれていることを確認することは、多くの頭痛の種を避けることができます。適切な構文に注意を払うことで、エラーにつながる多くの一般的な落とし穴を避けることができます。

まず最初にすべきことは、WordPressにウェブからスニペットを貼り付けるための初心者向けガイドを見ることです。この投稿では、WordPressテンプレートにコードを貼り付ける際に初心者が犯しがちな間違いをいくつか挙げています。

Example of a syntax error in WordPress

構文エラーは通常、コードの構文におけるわずかな、しかし重大なミスが原因です。例えば、カンマが抜けていたり、中カッコが余分にあったりすると、スクリプト全体が壊れてしまうことがある。

最近、ウェブからスニペットを貼り付けましたか?プラグインを更新しましたか?それなら、どこを見ればいいのかよくご存知でしょう。

FTPを使用した構文エラーの修正

構文エラーを修正するには、その原因となったコードを編集する必要があります。削除するか、構文を修正するかのどちらかです。

このエラーによってサイト全体がアクセス不能になるため、初心者はしばしばパニックに陥る。

WordPressダッシュボードの外観 ” エディターセクションを使用してコードを貼り付けた場合は、ロックアウトされています。WordPressの管理画面からロックアウトされた場合の対処法をご覧ください。

では、どうやってコードを編集するのか?

これを解決する唯一の方法は、FTPを使って最後に編集したファイルにアクセスすることです。ステップバイステップの手順については、FTPの使い方のガイドを参照してください。

FTPプログラムをインストーラした後、サイトに接続し、編集が必要なテーマファイルにアクセスしてください。編集が必要なファイルを忘れてしまった場合は、エラーコードを見てください。エラーは、あなたが編集する必要があるファイルと行を正確に教えてくれます。

最後に追加したコードを削除するか、正しい構文を使用してコードを記述します。コードの削除や編集が終わったら、ファイルを保存してサーバーにアップロードしてください。

その後、WordPressサイトにアクセスしてページを更新してください。サイトが再び機能していることが確認できるはずです。

WordPressで構文エラーを防ぐ方法

WordPressサイトが再び壊れないようにするには、WPCodeのようなコードスニペットプラグインでカスタムコードを追加することをお勧めします。

WPCode's homepage

WPCodeは、テーマのfunctions.phpファイルを編集することなく、WordPressにコードスニペットを簡単に追加することができます。また、エラーを防ぐためのスマートコードスニペット検証が付属しています。

カスタマイザーコードを追加すると、WPCodeは自動的にエラーを検出します。エラーの上にマウスオーバーすると、役立つ説明が表示されますので、簡単に間違いを修正することができます。

Smart code snippet validation to find code errors

WPCodeはまた、構文エラーを検出した場合、カスタムコードを直ちに無効化します。

このプラグインを使えば、コードスニペットを追加する際にサイトが壊れる心配はない。

    Hello,

    I got this error after I updated some plug ins,
    Parse error: syntax error, unexpected ‘var’ (T_VAR) in /home/smilesonbristol/public_html/wp-content/plugins/jetpack/sal/class.json-api-date.php on line 55

    Please help.

    • WPBeginner Support

      Hey Francisco,

      First you need to deactivate all WordPress plugins. After that activate them one by one until you get the error again. This will help you find out exactly which plugin is causing the error. You can then contact the plugin support.

    Here’s another one:
    logged on to the FTP (as suggested by this blog…thanks for that!!), found the files…. but couldn’t download them:
    ….Status: Starting download of /www/wp-admin/theme-editor.php
    Error: Failed to open “/theme-editor.php” for writing
    Error: File transfer failed…..

    idea? Anyone?

    • Raffy

      I had the same problem, a red error message when I tried to download it from the right-click window: so I simply searched for my desktop, dragged the file there, edited it, deleted the old functions.php file in my wordpress and dragged the new edited file in the same place. Hope this helps.

  8. Deb

    I cannot tell you how much you’ve saved my life!!! Well, my blog!!! Follow every step, guys!

  9. Kathleen

    I am getting this error. I did what you said, pasted in some code that didn’t work. When I took the pasted code out, it still gave me the error. So, fine, I just copied the whole file from a fresh download, and I’m still getting the same error, so I have no idea of what to do now.

  10. Stephen

    This article saved my life – lol. Thank you so much for the step by step. Fortunately, I had copied and pasted the good code into a text file so going back was easy after I understood what I was looking for.

    OMGosh, thank you for this post! That just happened to me, and I thought I had lost my site for good. What a relief to know the solution was as simple as using FTP.

    • Walter

      This error happen after I made the plugin´s update by WP Painel.. and now I can´t access the WP Painel anymore… only by FTP

  13. Mikael Andersen

    Would it be possible for the WP developer team to develop some kind of a script, that is checking out the code syntax in the functions.php file in order to prevent the user from saving the file if it contents any error.

    I think it could be of a big help for many users, especially if a user has taken a copy of the file before making any changes in it.

  14. Imran

    Hello guys ,

    Can anyone help me with this, I’m having an error when i check my blog health on I dont know how to fix this error. I have tried so hard but couldn’t fix it.

    Improper use of href attribute

    The href attribute specifies the URL of the page the link goes to. Without this attribute, the <a> is not a hyperlink.

    How to solve this issue

    This is essentially a broken link and therefore should be fixed asap so as to not affect SEO negatively.

    Thank you

    • WPBeginner Support

      Hi Imran,

      You will need to edit the post or page and locate the broken link and then delete it.

I got this error: Parse error: syntax error, unexpected ‘<' in C:\xampp 1\htdocs\wp\wp-content\themes\theme\keid-hosting\functions.php on line 43 and i now cant access my admin via the usual http://localhost/wp/wp-admin/.

    Ive tried to replace the functions.php file with an original from download and also i replaced all theme files with originals, still getting the error. I also tried to change the name of the theme and themes directory to try get it revert back to default theme (twentyfifteen etc…) but still getting the error

    Can you help me pls???

    Thanks in advance

    Hello –

    I have a similar error. The site had a theme and I changed it. It worked fine and I was customizing when the issue happened. When I go into FTP the new theme files are not there- only the old theme is shown. How can that be?

    I tried to upload the new theme here to overwrite whatever is causing it to stay down but nothing is working. Any advice?

    Thanks!

  35. Karen

    YOU are incredibly AWESOME! Your site will be carried around in my back pocket and shared with everyone I know that uses WP. Thank you for this valuable info. You saved my site!

  36. Andrew

    When I go to my website I get this error:

    Parse error: syntax error, unexpected ‘/’ in /home/cycletrk/public_html/wp-blog-header.php on line 12

    I know it’s a code error but I haven’t made any changes to the website for a while so the code just suddenly changed? I can log into the admin section site fine but I can’t find where this code is.

    Any help?

    • WPBeginner Support

      Try deactivating plugins. See how to deactivate all WordPress plugins when not able to access wp-admin. If this does not work, then try updating your WordPress site URL. Simply edit your wp-config.php file and add these two lines:

      define(‘WP_HOME’,’http://example.com’);
      define(‘WP_SITEURL’,’http://example.com’);

      Replace example.com with your own domain name. It is possible that your site URLs are changed and have an unexpected ‘/’ at the end of the URL. IF this does not work out, then try deleting .htaccess file. If the .htaccess method solves the problem, then remember to visit Settings -> Permalinks page and click on update button to refresh your permalinks.

    Life saver! FTP did the job

  38. WPBeginner Staff

    See our FTP Tutorial

    Once you are connected through FTP locate the file where you pasted the code. Most probably you added it in /wp-content/themes/yourthemename/functions.php

    Download the file to your computer. Edit it to remove the code and then upload it back to the server.

    Hey-

    I’ve downloaded FTP but I have no idea what to do once inside besides logging in. How do I find my error and correct it?

    A little more background:

    I was trying to change where an ad on my page was by the code. Put the code in wrong so I can’t log into the page now. No idea how to change it back.

    Thanks

    If i am using mamp as my wordpress server, but now I am locked out because of the “Parse error: syntax error, unexpected”, does this mean I need to get a ftp account in order to edit my error?

  41. Eric

    Hi – I was able to login to my FTP by am unable to open the functions.php file. I keep getting a file transfer failed message. Any advice? Thanks!

  42. GM

    I’ve been trying to correct the syntax error I made whilst building my site, but the mapping for where I’m being told the error is doesn’t appear to exist when I try to access the site through FZ. I’m guessing it’s a similar issue to Jose’s last month. Any advice? Thanks

  43. K

    I cannot connect my site to FZ, it says ” Could not connect to server ” I already installed wordpress. And now I cant access my site because I accidentally pasted theme_hooks into theme_function. I don’t know how to find my server. Please HELP me, thanks

  44. Jose

    Hello, After editing the Functions.php I received a parse error on a certain line. Although I knew what the problem is the site is hosted on wordpress.com I can’t access the file via FTP. Any recommendations?

    Hello,

    I got this error when I tried to access the my blog :(

    Parse error: syntax error, unexpected T_FUNCTION in /home/content/……../wp-content/plugins/easy-related-posts/easy_related_posts.php on line 75

    Please help. :(

  46. WPBeginner Staff

    Seems like your theme’s functions.php file is broken. Here is what you need to do. First connect to your website using an FTP client. Go to wp-content/themes/laboratory_child/ directory and then edit functions.php file. On line 20 you will see a closing curly bracket ‘ } ‘ This bracket is not supposed to be here.

    If this is a child theme, then you can backup your functions.php file and then delete it from your webserver. The parent theme’s functions.php file will take over.
