How do I prevent Wordpress from stripping the "at" sign (@) from the URL query string?


If you're using WordPress and are facing issues with the "at" sign (@) being stripped from your URL query strings, you're not alone. This issue can affect your ability to use certain URLs that require the "@" character, such as those containing email addresses, usernames, or other identifiers. In this article, we will explore this problem, analyze the underlying causes, and provide solutions to ensure your URLs function correctly.

Understanding the Problem

When you input a URL into your WordPress site that includes the "@" character, WordPress may automatically remove it or alter the way the URL is processed. This can lead to confusion and frustration, especially if you're relying on these URLs for functionality such as sharing links or redirecting users based on specific parameters.

Original Code Example

For instance, consider the following URL that you might want to use:

https://example.com/[email protected]

When this URL is processed by WordPress, you may find that the "@" sign is stripped, resulting in an altered URL that doesn't function as intended.

Analyzing the Issue

The reason behind WordPress stripping the "@" symbol from URLs is related to the way it sanitizes and handles URL parameters. WordPress implements various security measures to prevent the use of potentially harmful characters within URLs, and the "@" sign is one of them.

Common Scenarios

  1. Email Links: If you're trying to create a link that includes an email address, the "@" character is essential for it to function properly.

  2. Custom Query Strings: Developers often use "@" in custom query strings for various applications, and having WordPress modify these can disrupt functionality.

Solutions to the Problem

1. Use URL Encoding

One effective way to prevent WordPress from stripping the "@" sign is to use URL encoding. The "@" symbol can be represented as %40. For example, you would change the URL to:

https://example.com/?user=john%40example.com

By encoding the "@" sign, you maintain the intended meaning of the URL without WordPress modifying it.

2. Modify .htaccess

If you have access to your site’s .htaccess file, you can add rules to ensure that WordPress doesn't modify certain query strings. Be cautious when editing this file, as improper changes can affect your site’s functionality.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{QUERY_STRING} user=([^&]+)
RewriteRule ^$ index.php?user=$1 [L]
</IfModule>

This rule allows the "@" character to be retained in your URL parameters.

3. Adjusting Plugin Settings

Sometimes, the issue may arise due to the settings of a specific plugin. Check the configurations of any security or optimization plugins you are using, as they may have options that filter out certain characters.

4. Use Alternative Characters

In cases where the above solutions do not work, consider using alternative characters that could serve the same purpose, such as dashes (-) or underscores (_), while ensuring that they are understood within the context of your application.

Conclusion

Stripping the "@" sign from URL query strings can create challenges in WordPress, particularly if you're dealing with email addresses or custom parameters. By using URL encoding, adjusting your .htaccess file, or modifying plugin settings, you can successfully mitigate this issue.
