[6.x] Forms 2: Unique Instances

[duncanmcclean]

This pull request implements "unique instances" for forms: a Forms Pro feature which lets a form be treated as its own instance per entry, with submissions tracked against the entry they were submitted from, rather than in aggregate.

The classic use case is an Events collection where every event has its own RSVP form — each event gets its own submissions, its own capacity and its own close date, all from a single rsvp form.

Like multi-page forms, everything lives in core but is only available when the statamic/forms-pro addon is installed.

Enabling unique instances

Toggle on "Unique Instances" in the form's configure screen, then attach the form to entries using the form fieldtype.

The frontend

When {{ form:create }} is rendered in an entry's context, it outputs a hidden _entry input, and the submission is tracked against that entry.

Per-entry restrictions & overrides

When unique instances is enabled, the form's Access settings are evaluated per entry:

• Submission limits count only the entry's submissions (eg. "100 spots per event").
• Each entry can override the Access settings (close date, submission limit & period, closed message, require login & message) via the form fieldtype's "Configure" option. Fields are synced with the form's settings by default — editing a field desyncs it and stores an override, while synced fields keep following the form.

Connections are overridable in the same way, so each entry can have its own notifications. A warning banner is visible when configuring connections on a form with "unique instances" enabled.

In the Control Panel

The submissions listing shows which entry each submission came from, and can be filtered down to a single entry.

On the entry's publish form, the form fieldtype has a "View Submissions" option which opens the entry's submissions in a stack, with individual submissions opening in a nested stack. The fieldtype's index view links to the pre-filtered submissions listing, and the submission page links back to the entry.

PHP API

The form fieldtype's value is stored as a plain handle until an entry has overrides, at which point it becomes an array with form and config keys.

Restriction logic lives on a new Instance class, since "is this form open?" becomes a per-entry question when unique instances is enabled:

$form->instance($entryId)->status(); // open, closed, limit_reached
$form->instance($entryId)->restricted();
$form->instance($entryId)->restrictionMessage();
$form->instance($entryId)->config('submission_limit'); // entry override, falling back to the form
$form->instance($entryId)->connections(); // entry override, falling back to the form's own connections

// Every form has a "default" instance, which these delegate to:
$form->status();
$form->restricted();
$form->restrictionMessage();
