This plugin allows you to add a honeypot captcha to your Craft CMS guest entry form.
This plugin requires Craft CMS 3.0.0 or later, and the Guest Entries plugin.
You can install this plugin from the Plugin Store or with Composer.
Go to the Plugin Store in your project’s Control Panel and search for “Guest Entries Honeypot”. Then click on the “Install” button in its modal window.
Open your terminal and run the following commands:
# go to the project directory
cd /path/to/my-project.test
# tell Composer to load the plugin
composer require mikestecker/craft-guest-entries-honeypot
# tell Craft to install the plugin
./craft install/plugin guest-entries-honeypot
To configure the plugin, go to Settings → Guest Entries Honeypot, and choose a param name that your honeypot field should have.
Then edit your entry form template(s), and add the honeypot field.
<input id="secretHoneypotParamName" name="secretHoneypotParamName" type="text">
You can hide the field with CSS:
input#secretHoneypotParamName { display: none; }
