# Forms

<Warning>This is documentation for Inertia.js v1, which is no longer actively maintained. Please refer to the [v3 docs](/v3/getting-started/index).</Warning>

## Submitting Forms

While it's possible to make classic HTML form submissions with Inertia, it's not recommended since they cause full-page reloads. Instead, it's better to intercept form submissions and then make the [request using Inertia](/v1/the-basics/manual-visits).

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <template>
      <form @submit.prevent="submit">
          <label for="first_name">First name:</label>
          <input id="first_name" v-model="form.first_name" />
          <label for="last_name">Last name:</label>
          <input id="last_name" v-model="form.last_name" />
          <label for="email">Email:</label>
          <input id="email" v-model="form.email" />
          <button type="submit">Submit</button>
      </form>
  </template>

  <script>
  import { router } from '@inertiajs/vue2'

  export default {
      data() {
          return {
              form: {
                  first_name: null,
                  last_name: null,
                  email: null,
              },
          }
      },
      methods: {
          submit() {
              router.post('/users', this.form)
          },
      },
  }
  </script>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <script setup>
  import { reactive } from 'vue'
  import { router } from '@inertiajs/vue3'

  const form = reactive({
      first_name: null,
      last_name: null,
      email: null,
  })

  function submit() {
      router.post('/users', form)
  }
  </script>

  <template>
      <form @submit.prevent="submit">
          <label for="first_name">First name:</label>
          <input id="first_name" v-model="form.first_name" />
          <label for="last_name">Last name:</label>
          <input id="last_name" v-model="form.last_name" />
          <label for="email">Email:</label>
          <input id="email" v-model="form.email" />
          <button type="submit">Submit</button>
      </form>
  </template>
  ```

  ```jsx React icon="react" theme={null}
  import { useState } from 'react'
  import { router } from '@inertiajs/react'

  export default function Edit() {
      const [values, setValues] = useState({
          first_name: "",
          last_name: "",
          email: "",
      })

      function handleChange(e) {
          const key = e.target.id;
          const value = e.target.value
          setValues(values => ({
                  ...values,
                  [key]: value,
          }))
      }

      function handleSubmit(e) {
          e.preventDefault()
          router.post('/users', values)
      }

      return (
          <form onSubmit={handleSubmit}>
              <label htmlFor="first_name">First name:</label>
              <input id="first_name" value={values.first_name} onChange={handleChange} />
              <label htmlFor="last_name">Last name:</label>
              <input id="last_name" value={values.last_name} onChange={handleChange} />
              <label htmlFor="email">Email:</label>
              <input id="email" value={values.email} onChange={handleChange} />
              <button type="submit">Submit</button>
          </form>
      )
  }
  ```

  ```html Svelte icon="s" theme={null}
  <script>
      import { router } from '@inertiajs/svelte'

      let values = {
          first_name: null,
          last_name: null,
          email: null,
      }

      function handleSubmit() {
          router.post('/users', values)
      }
  </script>

  <form on:submit|preventDefault={handleSubmit}>
      <label for="first_name">First name:</label>
      <input id="first_name" bind:value={values.first_name}>

      <label for="last_name">Last name:</label>
      <input id="last_name" bind:value={values.last_name}>

      <label for="email">Email:</label>
      <input id="email" bind:value={values.email}>

      <button type="submit">Submit</button>
  </form>
  ```
</CodeGroup>

As you may have noticed in the example above, when using Inertia, you don't typically need to inspect form responses client-side like you would when making XHR / fetch requests manually.

Instead, your server-side route / controller typically issues a [redirect](/v1/the-basics/redirects) response. And, Of course, there is nothing stopping you from redirecting the user right back to the page they were previously on. Using this approach, handling Inertia form submissions feels very similar to handling classic HTML form submissions.

```php theme={null}
class UsersController extends Controller
{
        public function index()
        {
                return Inertia::render('Users/Index', [
                    'users' => User::all(),
                ]);
        }

        public function store(Request $request)
        {
                User::create($request->validate([
                    'first_name' => ['required', 'max:50'],
                    'last_name' => ['required', 'max:50'],
                    'email' => ['required', 'max:50', 'email'],
                ]));

                return to_route('users.index');
        }
}
```

## Server-side Validation

Handling server-side validation errors in Inertia works a little different than handling errors from manual XHR / fetch requests. When making XHR / fetch requests, you typically inspect the response for a `422`status code and manually update the form's error state.

However, when using Inertia, a `422` response is never returned by your server. Instead, as we saw in the example above, your routes / controllers will typically return a redirect response - much like a classic, full-page form submission.

For a full discussion on handling and displaying validation errors with Inertia, please consult the [validation](/v1/the-basics/validation) documentation.

## Form Helper

Since working with forms is so common, Inertia includes a form helper designed to help reduce the amount of boilerplate code needed for handling typical form submissions.

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <template>
      <form @submit.prevent="form.post('/login')">
          <!-- email -->
          <input type="text" v-model="form.email">
          <div v-if="form.errors.email">{{ form.errors.email }}</div>
          <!-- password -->
          <input type="password" v-model="form.password">
          <div v-if="form.errors.password">{{ form.errors.password }}</div>
          <!-- remember me -->
          <input type="checkbox" v-model="form.remember"> Remember Me
          <!-- submit -->
          <button type="submit" :disabled="form.processing">Login</button>
      </form>
  </template>

  <script>
  import { useForm } from '@inertiajs/vue2'

  export default {
      data() {
          return {
              form: useForm({
                  email: null,
                  password: null,
                  remember: false,
              }),
          }
      },
  }
  </script>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <script setup>
  import { useForm } from '@inertiajs/vue3'

  const form = useForm({
      email: null,
      password: null,
      remember: false,
  })
  </script>

  <template>
      <form @submit.prevent="form.post('/login')">
          <!-- email -->
          <input type="text" v-model="form.email">
          <div v-if="form.errors.email">{{ form.errors.email }}</div>
          <!-- password -->
          <input type="password" v-model="form.password">
          <div v-if="form.errors.password">{{ form.errors.password }}</div>
          <!-- remember me -->
          <input type="checkbox" v-model="form.remember"> Remember Me
          <!-- submit -->
          <button type="submit" :disabled="form.processing">Login</button>
      </form>
  </template>
  ```

  ```jsx React icon="react" theme={null}
  import { useForm } from '@inertiajs/react'

  const { data, setData, post, processing, errors } = useForm({
      email: '',
      password: '',
      remember: false,
  })

  function submit(e) {
      e.preventDefault()
      post('/login')
  }

  return (
      <form onSubmit={submit}>
          <input type="text" value={data.email} onChange={e => setData('email', e.target.value)} />
          {errors.email && <div>{errors.email}</div>}
          <input type="password" value={data.password} onChange={e => setData('password', e.target.value)} />
          {errors.password && <div>{errors.password}</div>}
          <input type="checkbox" checked={data.remember} onChange={e => setData('remember', e.target.checked)} /> Remember Me
          <button type="submit" disabled={processing}>Login</button>
      </form>
  )
  ```

  ```html Svelte icon="s" theme={null}
  <script>
  import { useForm } from '@inertiajs/svelte'

  let form = useForm({
      email: null,
      password: null,
      remember: false,
  })

  function submit() {
      $form.post('/login')
  }
  </script>

  <form on:submit|preventDefault={submit}>
      <input type="text" bind:value={$form.email} />
      {#if $form.errors.email}
          <div class="form-error">{$form.errors.email}</div>
      {/if}
      <input type="password" bind:value={$form.password} />
      {#if $form.errors.password}
          <div class="form-error">{$form.errors.password}</div>
      {/if}
      <input type="checkbox" bind:checked={$form.remember} /> Remember Me
      <button type="submit" disabled={$form.processing}>Submit</button>
  </form>
  ```
</CodeGroup>

To submit the form, you may use the `get`, `post`, `put`, `patch`and `delete` methods.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  form.submit(method, url, options)
  form.get(url, options)
  form.post(url, options)
  form.put(url, options)
  form.patch(url, options)
  form.delete(url, options)
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  form.submit(method, url, options)
  form.get(url, options)
  form.post(url, options)
  form.put(url, options)
  form.patch(url, options)
  form.delete(url, options)
  ```

  ```js React icon="react" theme={null}
  const { submit, get, post, put, patch, delete: destroy } = useForm({ ... })

  submit(method, url, options)
  get(url, options)
  post(url, options)
  put(url, options)
  patch(url, options)
  destroy(url, options)
  ```

  ```js Svelte icon="s" theme={null}
  $form.submit(method, url, options)
  $form.get(url, options)
  $form.post(url, options)
  $form.put(url, options)
  $form.patch(url, options)
  $form.delete(url, options)
  ```
</CodeGroup>

The submit methods support all of the typical [visit options](/v1/the-basics/manual-visits), such as `preserveState`, `preserveScroll`, and event callbacks, which can be helpful for performing tasks on successful form submissions. For example, you might use the `onSuccess` callback to reset inputs to their original state.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  form.post('/profile', {
      preserveScroll: true,
      onSuccess: () => form.reset('password'),
  })
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  form.post('/profile', {
      preserveScroll: true,
      onSuccess: () => form.reset('password'),
  })
  ```

  ```js React icon="react" theme={null}
  const { post, reset } = useForm({ ... })

  post('/profile', {
      preserveScroll: true,
      onSuccess: () => reset('password'),
  })
  ```

  ```js Svelte icon="s" theme={null}
  $form.post('/profile', {
      preserveScroll: true,
      onSuccess: () => $form.reset('password'),
  })
  ```
</CodeGroup>

If you need to modify the form data before it's sent to the server, you can do so via the `transform()` method.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  form
      .transform((data) => ({
          ...data,
          remember: data.remember ? 'on' : '',
      }))
      .post('/login')
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  form
      .transform((data) => ({
          ...data,
          remember: data.remember ? 'on' : '',
      }))
      .post('/login')
  ```

  ```js React icon="react" theme={null}
  const { transform } = useForm({ ... })

  transform((data) => ({
      ...data,
      remember: data.remember ? 'on' : '',
  }))
  ```

  ```js Svelte icon="s" theme={null}
  $form
      .transform((data) => ({
          ...data,
          remember: data.remember ? 'on' : '',
      }))
      .post('/login')
  ```
</CodeGroup>

You can use the `processing` property to track if a form is currently being submitted. This can be helpful for preventing double form submissions by disabling the submit button.

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <button type="submit" :disabled="form.processing">Submit</button>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <button type="submit" :disabled="form.processing">Submit</button>
  ```

  ```jsx React icon="react" theme={null}
  const { processing } = useForm({ ... })

  <button type="submit" disabled={processing}>Submit</button>
  ```

  ```svelte Svelte icon="s" theme={null}
  <button type="submit" disabled={$form.processing}>Submit</button>
  ```
</CodeGroup>

If your form is uploading files, the current progress event is available via the `progress` property, allowing you to easily display the upload progress.

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <progress v-if="form.progress" :value="form.progress.percentage" max="100">
      {{ form.progress.percentage }}%
  </progress>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <progress v-if="form.progress" :value="form.progress.percentage" max="100">
      {{ form.progress.percentage }}%
  </progress>
  ```

  ```jsx React icon="react" theme={null}
  const { progress } = useForm({ ... })

  {progress && (
      <progress value={progress.percentage} max="100">
          {progress.percentage}%
      </progress>
  )}
  ```

  ```svelte Svelte icon="s" theme={null}
  {#if $form.progress}
      <progress value={$form.progress.percentage} max="100">
          {$form.progress.percentage}%
      </progress>
  {/if}
  ```
</CodeGroup>

If there are form validation errors, they are available via the `errors` property. When building Laravel powered Inertia applications, form errors will automatically be populated when your application throws instances of `ValidationException`, such as when using `{'$request->validate()'}`.

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <div v-if="form.errors.email">{{ form.errors.email }}</div>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <div v-if="form.errors.email">{{ form.errors.email }}</div>
  ```

  ```jsx React icon="react" theme={null}
  const { errors } = useForm({ ... })

  {errors.email && <div>{errors.email}</div>}
  ```

  ```svelte Svelte icon="s" theme={null}
  {#if $form.errors.email}
      <div>{$form.errors.email}</div>
  {/if}
  ```
</CodeGroup>

For a more thorough discussion of form validation and errors, please consult the [validation documentation](/v1/the-basics/validation).

To determine if a form has any errors, you may use the `hasErrors` property. To clear form errors, use the `clearErrors()` method.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  // Clear all errors...
  form.clearErrors()

  // Clear errors for specific fields...
  form.clearErrors('field', 'anotherfield')
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  // Clear all errors...
  form.clearErrors()

  // Clear errors for specific fields...
  form.clearErrors('field', 'anotherfield')
  ```

  ```js React icon="react" theme={null}
  const { clearErrors } = useForm({ ... })

  // Clear all errors...
  clearErrors()

  // Clear errors for specific fields...
  clearErrors('field', 'anotherfield')
  ```

  ```js Svelte icon="s" theme={null}
  // Clear all errors...
  $form.clearErrors()

  // Clear errors for specific fields...
  $form.clearErrors('field', 'anotherfield')
  ```
</CodeGroup>

If you're using a client-side input validation libraries or do client-side validation manually, you can set your own errors on the form using the `setErrors()` method.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  // Set a single error...
  form.setError('field', 'Your error message.');

  // Set multiple errors at once...
  form.setError({
      foo: 'Your error message for the foo field.',
      bar: 'Some other error for the bar field.'
  });
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  // Set a single error...
  form.setError('field', 'Your error message.');

  // Set multiple errors at once...
  form.setError({
      foo: 'Your error message for the foo field.',
      bar: 'Some other error for the bar field.'
  });
  ```

  ```js React icon="react" theme={null}
  const { setError } = useForm({ ... })

  // Set a single error...
  setError('field', 'Your error message.');

  // Set multiple errors at once...
  setError({
      foo: 'Your error message for the foo field.',
      bar: 'Some other error for the bar field.'
  });
  ```

  ```js Svelte icon="s" theme={null}
  // Set a single error
  $form.setError('field', 'Your error message.');

  // Set multiple errors at once
  $form.setError({
      foo: 'Your error message for the foo field.',
      bar: 'Some other error for the bar field.'
  });
  ```
</CodeGroup>

Unlike an actual form submission, the page's props remain unchanged when manually setting errors on a form instance.

When a form has been successfully submitted, the `wasSuccessful` property will be `true`. In addition to this, forms have a `recentlySuccessful` property, which will be set to `true` for two seconds after a successful form submission. This property can be utilized to show temporary success messages.

To reset the form's values back to their default values, you can use the `reset()` method.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  // Reset the form...
  form.reset()

  // Reset specific fields...
  form.reset('field', 'anotherfield')
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  // Reset the form...
  form.reset()

  // Reset specific fields...
  form.reset('field', 'anotherfield')
  ```

  ```js React icon="react" theme={null}
  const { reset } = useForm({ ... })

  // Reset the form...
  reset()

  // Reset specific fields...
  reset('field', 'anotherfield')
  ```

  ```js Svelte icon="s" theme={null}
  // Reset the form...
  $form.reset()

  // Reset specific fields...
  $form.reset('field', 'anotherfield')
  ```
</CodeGroup>

If your form's default values become outdated, you can use the `defaults()` method to update them. Then, the form will be reset to the correct values the next time the `reset()` method is invoked.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  // Set the form's current values as the new defaults...
  form.defaults()

  // Update the default value of a single field...
  form.defaults('email', 'updated-default@example.com')

  // Update the default value of multiple fields...
  form.defaults({
      name: 'Updated Example',
      email: 'updated-default@example.com',
  })
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  // Set the form's current values as the new defaults...
  form.defaults()

  // Update the default value of a single field...
  form.defaults('email', 'updated-default@example.com')

  // Update the default value of multiple fields...
  form.defaults({
      name: 'Updated Example',
      email: 'updated-default@example.com',
  })
  ```

  ```js React icon="react" theme={null}
  const { setDefaults } = useForm({ ... })

  // Set the form's current values as the new defaults...
  setDefaults()

  // Update the default value of a single field...
  setDefaults('email', 'updated-default@example.com')

  // Update the default value of multiple fields...
  setDefaults({
      name: 'Updated Example',
      email: 'updated-default@example.com',
  })
  ```

  ```js Svelte icon="s" theme={null}
  // Set the form's current values as the new defaults...
  $form.defaults()

  // Update the default value of a single field...
  $form.defaults('email', 'updated-default@example.com')

  // Change the default value of multiple fields...
  $form.defaults({
      name: 'Updated Example',
      email: 'updated-default@example.com',
  })
  ```
</CodeGroup>

To determine if a form has any changes, you may use the `isDirty` property.

<CodeGroup>
  ```vue Vue 2 icon="vuejs" theme={null}
  <div v-if="form.isDirty">There are unsaved form changes.</div>
  ```

  ```vue Vue 3 icon="vuejs" theme={null}
  <div v-if="form.isDirty">There are unsaved form changes.</div>
  ```

  ```jsx React icon="react" theme={null}
  const { isDirty } = useForm({ ... })

  {isDirty && <div>There are unsaved form changes.</div>}
  ```

  ```html Svelte icon="s" theme={null}
  {#if $form.isDirty}
      <div>There are unsaved form changes.</div>
  {/if}
  ```
</CodeGroup>

To cancel a form submission, use the `cancel()` method.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  form.cancel()
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  form.cancel()
  ```

  ```js React icon="react" theme={null}
  const { cancel } = useForm({ ... })

To instruct Inertia to store a form's data and errors in [history state](/v1/advanced/remembering-state), you can provide a unique form key as the first argument when instantiating your form.

<CodeGroup>
  ```js Vue 2 icon="vuejs" theme={null}
  import { useForm } from '@inertiajs/vue2'

  form: useForm('CreateUser', data)
  form: useForm(`EditUser:${this.user.id}\
  ```

  ```js Vue 3 icon="vuejs" theme={null}
  import { useForm } from '@inertiajs/vue3'

  const form = useForm('CreateUser', data)
  const form = useForm(`EditUser:${user.id}\
  ```

  ```js React icon="react" theme={null}
  import { useForm } from '@inertiajs/react'

  const form = useForm('CreateUser', data)
  const form = useForm(`EditUser:${user.id}\
  ```

  ```js Svelte icon="s" theme={null}
  import { useForm } from '@inertiajs/svelte'

  const form = useForm('CreateUser', data)
  const form = useForm(`EditUser:${user.id}\
  ```
</CodeGroup>

## File Uploads

When making requests or form submissions that include files, Inertia will automatically convert the request data into a `FormData` object.

For a more thorough discussion of file uploads, please consult the [file uploads documentation](/v1/the-basics/file-uploads).

## XHR / Fetch Submissions

Using Inertia to submit forms works great for the vast majority of situations; however, in the event that you need more control over the form submission, you're free to make plain XHR or `fetch` requests instead using the library of your choice.
