Form inputs can have specially named name-attributes, which alter functionality. They are all prefixed with an underscore.

_replyto

This value is used for the email's Reply-To field. This way you can directly "Reply" to the email to respond to the person who originally submitted the form.

To activate this feature your form should request the user's email address.

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

_next

By default, after submitting a form the user is shown the FormSubmit "Thank You" page. You can provide an alternative URL for "Thank You" page.

<input type="hidden" name="_next" value="https://yourdomain.co/thanks.html">

_subject

This value is used for the email's subject, so that you can quickly reply to submissions without having to edit the subject line each time.

<input type="hidden" name="_subject" value="New submission!">

_cc

This value is used for the email's CC Field. This lets you send a copy of each submission to another email address.

<input type="hidden" name="_cc" value="another@email.com">

If you want to CC multiple email addresses, then just make it a list of email addresses separate by commas.

<input type="hidden" name="_cc" value="another@email.com,yetanother@email.com">

_honey

Add this "honeypot" field to avoid spam by fooling scrapers. If a value is provided, the submission will be silently ignored. The input should be hidden with CSS.

All forms come with reCAPTCHA, which uses advanced machine learning techniques to distinguish between humans and bots, so for most forms this isn't necessary.

<input type="text" name="_honey" style="display:none">

Disable reCAPTCHA _captcha

Don't want your users to complete a reCAPTCHA? Each form now comes with the option to disable the reCAPTCHA, so you can maintain complete control over your form. You can even keep reCAPTCHA on a few forms that might be suceptible to spam, while disabling it on others.

<input type="hidden" name="_captcha" value="false">

_autoresponse

You can send an instant response to your users with a copy of the submission. Add a custom message to the email body.

<input type="hidden" name="_autoresponse" value="your custom message">

To activate this feature your form should request the user's email address.

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

* autoresponse won't work with forms that are disabled reCAPTCHA and forms that are submitting through AJAX.

_template

You can select an email template from 3 different templates. By default, FormSubmit uses the basic template.

<input type="hidden" name="_template" value="table">

_webhook

This feature allows you to configure a webhook that will be triggered each time a form receives a new submission. Webhooks can be used to manipulate data in real-time.

<input type="hidden" name="_webhook" value="https://yourdomain.co/your-webhook">
