原文外掛簡介
Contact Camo protects email addresses from scrapers and bots — now with a native Gutenberg block so you can build beautiful, protected contact experiences without touching a single line of code.
What Is It?
Contact Camo is a plugin for WordPress developed by Plan Left that effectively hides or obfuscates email addresses from scammers, web scrapers and internet bots to help minimize spam and other nefarious, automated actors.
In addition to protecting email addresses, Contact Camo provides rich, visual control over how those protected email addresses are displayed and interacted with by your visitors — all from inside the WordPress block editor.
Now with a Native Gutenberg Block!
Contact Camo now feels right at home in the WordPress block editor. Drag it in, configure it visually, and see a live preview of exactly what your visitors will see — no shortcodes, no guesswork.
Everything is point-and-click:
🎨 Pick an icon — Browse and search hundreds of WordPress icons right inside the sidebar. Choose your size from XS to XL, or dial in an exact pixel size.
🖌️ Choose a color — Set the text and icon color using your theme’s color palette or a custom color picker. It just works.
🔘 Link or button? — Toggle between a standard link and a styled button in one click. Your theme’s button styles apply automatically.
📋 Inline or popup form? — Show a sleek embedded contact form or a modal popup — your choice, configured visually.
📐 Control the layout — Adjust container padding and form width to fit perfectly within your design.
👁️ Show what you want — Display the icon and text together, icon only, or text only. You decide.
⚡ Live preview — Every change you make is reflected instantly in the editor canvas. What you see is what you get.
All of the above is available through the shortcode too, for those who prefer it.
Example Use Cases
Educational Organization with large faculty directories
Nonprofits who need to be accessible without displaying in-content email addresses
Large Organizations who have departmental pages and points of contact but don’t want to maintain multiple contact forms
Anyone who doesn’t want to expose email addresses to the scammers, scrapers and bots of the internet.
Why Did You Make This Plugin?
We work with many non-profits and educational organizations that need to list contact info in directories on their website. Due to the public visibility of these and their large user base, our clients’ web properties are under constant threat from spammers and bots. We wanted to ensure that their user directories were safe from these threats while still being functional to visitors. In other words, we needed to hide a bunch of email addresses from the outside world while still allowing the outside world to contact those users via their email address. When we got to developing this plugin, we knew we had to provide a solution that was as bulletproof as possible while allowing our clients and customers the most amount of control over things as practical.
Ultimately, we needed to create a plugin that would:
Optionally hide or obfuscate email addresses from scrapers and bots securely and confidently. For our use case, email addresses needed to be obfuscated in the source code, the DOM, and in HTTP requests. We took the email address out of the client-side equation completely by just tucking it safely away in the database in a lookup table instead of providing a workaround that simply disguises the email address. We essentially took the email address to a safe house and sent out its representative to interact with the outside world on its behalf. Nobody gets the email, not no way, not no how, see?!?
Provide users with lots of control over the UX of protected email addresses, without the need for cumbersome configuration. The Gutenberg block handles all of that visually, and the shortcode is still there for power users.
Be performant in capabilities, lightweight in footprint, and opinionated in scope.
The client was very pleased with the end-result and so were we. So, we decided to offer it back to the community. Our development team reviewed and scrutinized the existing plugin, found areas for improvements and further customizations, and baked them right in for everyone to use.
Who Is It For?
Site administrators and content editors/moderators. Anyone with a WordPress site that would like the peace of mind of knowing that their users’ email addresses are safely hidden from spam bots and other unintended consumers with ill intent. Content creators that don’t want to worry about the complications and time expenditure of dealing with and managing their user base getting spammed from their platform. And especially when any of the above mentioned require some level of control over what’s displayed to their users, who may very well be their customers or clients or patients, etc… It’s for site builders that want protection AND customization without being overwhelmed.
With the new Gutenberg block, that means literally anyone editing a page in WordPress — no code required.
What Problems Does It Solve?
Contact Camo hides or obfuscates email addresses in the source code AND the DOM. Not only this, it ensures the unobfuscated email address is never used in any page or ajax request from its originating context; all handling/processing is done server-side. Once obfuscated, the client-side never sees the original email address again (where obfuscated). The obfuscation (key) is a hash that is stored in a lookup table with the original email address.
A few of the limitations we found in some existing (but great) plugins:
email address only obfuscated in DOM, but not in source code
email address only obfuscated in source code, but not in the DOM
integrating with a 3rd-party service that scrapes entire pages and performs a search-and-replace of email addresses with obfuscated versions in the source code
email address obfuscation using only html entities replacement
few options for controlling output
no contact form or fallback options
no native block editor support
How Does It Work?
With the Gutenberg block (recommended): Search for “Contact Camo” in the block inserter, drop it onto your page, enter the email address you want to protect, and configure everything else from the visual sidebar. Done. You’ll see a live preview of the output right there in the editor.
With the shortcode: Contact Camo provides a simple shortcode that can be placed anywhere shortcodes are supported. The shortcode’s default output is a clickable link with the obfuscated email address’s generated hash stored in a data attribute. On click, this hash is used to look up the email address and then open the browser’s configured email client with the “To” field pre-populated.
The shortcode accepts parameters for overriding the default output — output a button instead of a link, add CSS classes, change the text output, choose an icon, set a color, and more.
The shortcode also supports an embedded contact form or an optional modal popup contact form as an alternative to triggering the email client.
What is Hide vs Obfuscate?
For our plugin, we wanted to give site administrators the option to either completely hide the email address and never let any end content consumer see any piece of the email, or to hide the email until requested and reveal it in context after a specific action is taken.
Hiding the email address: The site visitor will never see the email address, and instead only be presented a popup contact form that submits and mails through ajax. This option totally hides the email, and it will never be revealed unless the emailed recipient emails the form submitter back.
Obfuscating the email address: The site visitor will not see the email address until the contact button (or link) is clicked. On click, the email address will be revealed and the visitor can copy or mail to that address.
What Can I Do With It?
We chose to err on the side of simplicity, balanced with enough options to be truly useful. The Gutenberg block makes all of these options accessible without writing a single line of code:
Show a link or a button — your theme’s styles applied automatically
Add an icon from a library of hundreds, with full size control
Set a custom text and icon color using your theme palette or a custom picker
Show only the icon, only the text, or both
Display an inline contact form or a modal popup form
Control padding, form width, and layout
Add a custom CSS class or anchor ID for targeting with your own styles or JavaScript
All of the above is also available via the shortcode for developers and power users.
