How to Add Hidden Fields in OptinMonster

Looking to add hidden fields in OptinMonster? This can easily be done using our Custom HTML Optin Form integration option and following this guide.

Hidden input fields are identifiable by the type attribute, and do not appear visible to your visitors but allow you to pass additional details with your form.

The following is an example of a simple HTML form including two input fields to collect the name and email address and a hidden input field that specifies the language.

<form src="http://www.example.com/form.php" method="post">

   <input type="text" name="name" placeholder="Name" />

   <input type="email" name="email" placeholder="Email Address" />

   <input type="hidden" name="Language" value="English">

   <input type="submit" name="submit" value="Submit" />

</form>
IMPORTANT: the name and value attributes are always required for hidden fields.
