Update Form

Write

Ninja Forms Forms ninjaforms/update-form

Update a form's settings — title, display, submission limits, calculator currency, and more.

Requires the Ninja Forms plugin on WordPress 6.9+ for the Abilities API (all 32 abilities are registered only when the wp_register_ability() function exists, via NF_Abilities_Integration::load_abilities_api() running on plugins_loaded). Every ability is gated by the same ninja_forms_ability_can_manage_forms() permission callback, requiring the caller to hold WordPress's manage_options capability or Ninja Forms' own nf_edit_forms capability.

What it does

This ability updates any subset of a form's dashboard-level settings: title, title visibility and heading level, default label position, post-submission behavior (clear/hide), AJAX submit, login requirement, public-link access, submission limits and their message, custom CSS classes, and the currency used by calculator forms. Only the fields supplied are changed; everything else on the form is left untouched. This lets an AI assistant make configuration tweaks — like raising a submission cap or switching a form to require login — directly from a conversation instead of the user opening the form's Settings tab.
