Advanced Content Copy is a WordPress plugin that automatically modifies content when users copy text from your website. It adds customizable attribution text and links to help protect your content and drive traffic back to your site. The plugin intelligently detects the page type (single posts, categories, archives, etc.) and provides the appropriate URL for attribution.
Key Features:
<ul>
<li>Customizable Attribution: Add your own prefix and suffix text to copied content</li>
<li>Snippet Length Control: Limit the amount of text that gets copied with customizable character limits</li>
<li>Domain Attribution: Automatically include your site name or custom domain text</li>
<li>Page Exclusion: Exclude specific pages or posts from copy modification</li>
<li>Minimum Character Threshold: Only modify copies that meet a minimum character count</li>
<li>Clean Implementation: Uses WordPress best practices with proper enqueue functions</li>
<li>Smart URL Detection: Automatically detects page types and provides correct attribution URLs for posts, categories, archives, and more</li>
</ul>
How It Works:
When a user selects and copies text from your website, the plugin automatically: 
1. Checks if the copied text meets the minimum character requirement 
2. Truncates the text if it exceeds the snippet length limit 
3. Adds your custom attribution text and site URL 
4. Places the modified content in the user’s clipboard
Example Output: 
 <code>Original copied text: "This is a long article about WordPress development..." 
Modified clipboard content: "This is a long article about WordPress development... (This excerpt was copied from My Website; learn more at: https://mysite.com/post-url)"</code>

This plugin adds attribution inputs to the media uploader and “edit media” page. It includes a number of creative common license, public domain, fair use, and standard copyright. It will link back to the author’s page at either the end of a post/page and/or the attachment page. If you have a Flickr API key, it can automatically pull information for Flickr images (copyright, author name, title, description, etc). 
It adds a few settings to the Media settings page. You can add a Flickr API key, or display Creative Common logos for their respective licenses.
To style the attributions, I’ve added these CSS classes:
<ul>
<li>a2k-container – A div that contains all of the other elements</li>
<li>a2k-sources – Contains the text “Source:” or “Sources:” depending on the context</li>
<li>a2k-title – The attachment title</li>
<li>a2k-copyright – The copyright information. It may or may not contain an img tag, depending on your settings</li>
<li>a2k-author – The author information. If an author link is provded, it will contain an a tag.</li>
</ul>
