People searching “Laravel Vue validation errors” want the sentence under the input. The [CRUD guide](https://laravel-vuejs.space/laravel-inertia-vue-crud) already posts the form. This page is only that sentence.

> **TL;DR**

> -   Put the Laravel validation message under the matching Vue input.
> -   Inertia already sends form.errors.
> -   Do not return `response()->json(['errors' => ...], 422)` from an Inertia route.
> -   Do not pass `$request->all()` into `Post::create()`.

## The fix

A failed `validate()` throws `ValidationException`. Inertia turns it into a redirect back to this page. It does not show you a 422 in the Vue catch. `form.errors.title` is the first message for that field.

```vue
<script setup lang="ts">
import { useForm } from "@inertiajs/vue3";

const form = useForm({ title: "" });

function submit() {
  form.post("/posts");
}
</script>

<template>
  <form @submit.prevent="submit">
    <input v-model="form.title" name="title" />
    <p v-if="form.errors.title">{{ form.errors.title }}</p>
    <button type="submit">Save</button>
  </form>
</template>
```

```php
$validated = $request->validate([
    'title' => ['required', 'string', 'max:120'],
]);

Post::create(['title' => $validated['title'], 'user_id' => $request->user()->id]);
```

The input name, the `v-model` key, and the rule key have to be the same word. `form.errors.title` stays empty when the rule was `name` and the input was `title`.

## What to avoid

> **Gotcha**
>
> Do not return `response()->json(['errors' => ...], 422)` from an Inertia route. The client is waiting for a redirect. Do not pass `$request->all()` into `Post::create()`.
