Fluent Validation Rector

Appearance

Wildcard grouping ​

GroupWildcardRulesToEachRector ​

Folds flat wildcard and dotted keys into nested each() / children() calls, in FormRequests and Livewire components alike. When the folded children are FluentSchema chains, the synthesized parent is emitted in instance form ($rules->array()->children([...])) to match the receiver.

php
// Before
'tags'   => FluentRule::array()->nullable(),
'tags.*' => FluentRule::string()->max(50),

// After
'tags' => FluentRule::array()->nullable()->each(
    FluentRule::string()->max(50),
),

On Livewire this is safe: the HasFluentValidation trait's getRules() flattens the nested form back to wildcard keys at runtime.

Bail conditions

Each emits its own skip-log entry under =actionable:

  • A wildcard group with non-FluentRule entries, such as 'items' => ['required', ...] beside 'items.*' => FluentRule::....
  • A parent factory without each() / children(). Only FluentRule::array() and FluentRule::field() have them.
  • A wildcard parent (items.*) carrying type-specific rules that folding would silently drop.
  • A double wildcard (**), or a non-first * in a key suffix.
  • A concat-keyed wildcard ($prefix . '.*.foo') whose prefix is not a static class constant.
  • Branched-return bodies (several top-level returns) bail uniformly, rather than rewrite across branches.
Edge cases it handles
  • A dot-notation key with no explicit parent gets a synthesized bare FluentRule::array() parent, so nested required children still fire.
  • A FluentRule::field()->…->rule(Rule::array()) parent is promoted to array() before folding, because the array factory seeds the same implicit rule, but only array() exposes each(). Gated to provably equivalent chains: no label arg on the field() root, the only rule hop is the bare array rule, and every other hop exists on both FieldRule and ArrayRule. Labeled parents, FieldRule-only methods, conditionable closures, object-valued ->rule(...) hops, a message() bound to the array rule, keyed Rule::array([...]) and macro-based size constraints keep the escape hatch.
  • Wildcard-prefix concat keys ('*.' . CONST_NAME => …) fold when every sibling resolves its suffix from a self/static class constant. A mixed group keeps its literal-keyed entries and bails-with-log on the const branch. Partial conversion, no rule loss.
  • rules() returning RuleSet::from([...]) folds by descending into the array argument; the wrapper stays intact.
