Use this CF7 extension to enable OTP links to be inserted into confirmation\/notification emails sent to email addresses submitted through your CF7 forms. The OTP is a unique link the email inbox user needs to click to confirm their address. The link is valid by default for 72 hours and can be customised.<\/p>\n\n\n
[otp-<field-name>]<\/code> will be available to insert into your notification\/confirmation email which will all a unique time-limited URL for users to confirm their email.<\/li>\n- In the form editor page, the OTP tab allows you to set the pages to redirect to when an email is validated or fails due to an outdated link.<\/li>\n<\/ol>\n\n\n
\n0. What does this plugin do ?<\/h3><\/dt>\nIf you are collecting an email address in your CF7 form from a visitor, you can use this plugin to validate that email.<\/p>\n\n
The email field name will be used to create a unique OTP mail tag shortcode to insert into your notification mail (sent to that email). The shortcode will be replaced by a unique URL which the recipient can click on to validate their email. This unique link is created using WordPress nonce API, and it stored in the DB as a transient with a default validity of 72 hours (3 days). You can customise this validity period, please refer to the FAQ below for more details. When a recipient clicks on a valid link, they are redirected to the On Success<\/em> page you configured in the OTP tab. If the link is no longer valid, they are taken to the On failure<\/em> page instead, where you may give them the option to send them a new OTP link.<\/p>\n\nYou can use this plugin to go beyond simple email validation, as each valid user now has a unique way to identify themselves on your server. I have used this plugin to create a conference registration and submission form for speakers without having them to actually create a user account on the server. A visitor registers as a speaker, and once their email is validated, they use their OTP link (which expires a week prior to the conference start date) in order to submit talks for the conference without having to have an account.<\/p>\n\n
