Adding Additional Consent Checkboxes at Checkout

Requiring members to agree to terms or provide consent can be a requirement for many membership sites. Paid Memberships Pro allows you to add a single Terms of Service (TOS) agreement by default. When members agree, the “Terms of Service” tab records their consent as TOS Consent History. But you’ll need more flexibility if you have multiple terms or policies.

This recipe allows you to add additional required consent checkboxes at checkout and records each agreement in the Terms of Service tab in the Edit Member area. Use it to ensure members acknowledge all necessary terms before completing their purchase.

Understanding the Code Recipe

Using the  pmpro_checkout_before_submit_button filter,  the code dynamically adds checkboxes for each page that requires consent.
These checkboxes appear at checkout, requiring members to agree to all terms before proceeding. The agreements are validated before checkout and logged after completion, capturing details like the document version and timestamp.

Your additional pages will appear as links with a checkbox near the end of your checkout page. Users must agree to all checkboxes to complete the checkout process.
