Validation

Getting started

Validation rules may be added to any field.

Filament includes several dedicated validation methods, but you can also use any other Laravel validation rules, including custom validation rules.

Beware that some validations rely on the field name and therefore won't work when passed via ->rule()/->rules(). Use the dedicated validation methods whenever you can.

Available rules

Active URL

The field must have a valid A or AAAA record according to the dns_get_record() PHP function. See the Laravel documentation

Field::make('name')->activeUrl()

After (date)

The field value must be a value after a given date. See the Laravel documentation

Field::make('startDate')->after('tomorrow')

Alternatively, you may pass the name of another field to compare against:

Field::make('startDate')
Field::make('endDate')->after('startDate')

After or equal to (date)

The field value must be a date after or equal to the given date. See the Laravel documentation

Field::make('startDate')->afterOrEqual('tomorrow')

Alternatively, you may pass the name of another field to compare against:

Field::make('startDate')
Field::make('endDate')->afterOrEqual('startDate')

Alpha

The field must be entirely alphabetic characters. See the Laravel documentation

Field::make('name')->alpha()

Alpha Dash

The field may have alpha-numeric characters, as well as dashes and underscores. See the Laravel documentation

Field::make('name')->alphaDash()

Alpha Numeric

The field must be entirely alpha-numeric characters. See the Laravel documentation

Field::make('name')->alphaNum()

Before (date)

The field value must be a date before a given date. See the Laravel documentation

Field::make('startDate')->before('first day of next month')

Alternatively, you may pass the name of another field to compare against:

Field::make('startDate')->before('endDate')
Field::make('endDate')

Before or equal to (date)

The field value must be a date before or equal to the given date. See the Laravel documentation

Field::make('startDate')->beforeOrEqual('end of this month')

Alternatively, you may pass the name of another field to compare against:

Field::make('startDate')->beforeOrEqual('endDate')
Field::make('endDate')

Confirmed

The field must have a matching field of {field}_confirmation. See the Laravel documentation

Field::make('password')->confirmed()
Field::make('password_confirmation')

Different

The field value must be different to another. See the Laravel documentation

Field::make('backupEmail')->different('email')

Doesnt Start With

The field must not start with one of the given values. See the Laravel documentation

Field::make('name')->doesntStartWith(['admin'])

Doesnt End With

The field must not end with one of the given values. See the Laravel documentation

Field::make('name')->doesntEndWith(['admin'])

Field::make('status')->enum(MyStatus::class)

Exists

The field value must exist in the database. See the Laravel documentation.

Field::make('invitation')->exists()

By default, the form's model will be searched, if it is registered. You may specify a custom table name or model to search:

use App\Models\Invitation;
 
Field::make('invitation')->exists(table: Invitation::class)

By default, the field name will be used as the column to search. You may specify a custom column to search:

Field::make('invitation')->exists(column: 'id')

You can further customize the rule by passing a closure to the callback parameter:

use Illuminate\Validation\Rules\Exists;
 
Field::make('invitation')
->exists(callback: function (Exists $rule) {
return $rule->where('is_active', 1);
})

Filled

The field must not be empty when it is present. See the Laravel documentation

Field::make('name')->filled()

Greater than

The field value must be greater than another. See the Laravel documentation

Field::make('newNumber')->gt('oldNumber')

Greater than or equal to

The field value must be greater than or equal to another. See the Laravel documentation

Field::make('newNumber')->gte('oldNumber')

In

The field must be included in the given list of values. See the Laravel documentation

Field::make('status')->in(['pending', 'completed'])

Ip Address

The field must be an IP address. See the Laravel documentation

Field::make('ip_address')->ip()
Field::make('ip_address')->ipv4()
Field::make('ip_address')->ipv6()

JSON

The field must be a valid JSON string. See the Laravel documentation

Field::make('ip_address')->json()

Less than

The field value must be less than another. See the Laravel documentation

Field::make('newNumber')->lt('oldNumber')

Field::make('mac_address')->macAddress()

Multiple Of

The field must be a multiple of value. See the Laravel documentation

Field::make('number')->multipleOf(2)

Not In

The field must not be included in the given list of values. See the Laravel documentation

Field::make('status')->notIn(['cancelled', 'rejected'])

Not Regex

The field must not match the given regular expression. See the Laravel documentation

Field::make('email')->notRegex('/^.+$/i')

Nullable

The field value can be empty. This rule is applied by default if the required rule is not present. See the Laravel documentation

Field::make('name')->nullable()

Required

The field value must not be empty. See the Laravel documentation

Field::make('name')->required()

Required With

The field value must not be empty only if any of the other specified fields are not empty. See the Laravel documentation

Field::make('name')->requiredWith('field,another_field')

Required With All

The field value must not be empty only if all of the other specified fields are not empty. See the Laravel documentation

Field::make('name')->requiredWithAll('field,another_field')

Required Without

The field value must not be empty only when any of the other specified fields are empty. See the Laravel documentation

Field::make('name')->requiredWithout('field,another_field')

Required Without All

The field value must not be empty only when all of the other specified fields are empty. See the Laravel documentation

Field::make('name')->requiredWithoutAll('field,another_field')

Regex

The field must match the given regular expression. See the Laravel documentation

Field::make('email')->regex('/^.+@.+$/i')

Same

The field value must be the same as another. See the Laravel documentation

Field::make('password')->same('passwordConfirmation')

Starts With

The field must start with one of the given values. See the Laravel documentation

Field::make('name')->startsWith(['a'])

String

The field must be a string. See the Laravel documentation

Field::make('name')->string()

Unique

The field value must not exist in the database. See the Laravel documentation

Field::make('email')->unique()

By default, the form's model will be searched, if it is registered. You may specify a custom table name or model to search:

use App\Models\User;
 
Field::make('email')->unique(table: User::class)

By default, the field name will be used as the column to search. You may specify a custom column to search:

Field::make('email')->unique(column: 'email_address')

Sometimes, you may wish to ignore a given model during unique validation. For example, consider an "update profile" form that includes the user's name, email address, and location. You will probably want to verify that the email address is unique. However, if the user only changes the name field and not the email field, you do not want a validation error to be thrown because the user is already the owner of the email address in question.

Field::make('email')->unique(ignorable: $ignoredUser)

If you're using the admin panel, you can easily ignore the current record by using ignoreRecord instead:

Field::make('email')->unique(ignoreRecord: true)

You can further customize the rule by passing a closure to the callback parameter:

use Illuminate\Validation\Rules\Unique;
 
Field::make('email')
->unique(callback: function (Unique $rule) {
return $rule->where('is_active', 1);
})

UUID

The field must be a valid RFC 4122 (version 1, 3, 4, or 5) universally unique identifier (UUID). See the Laravel documentation

Field::make('identifer')->uuid()

Other rules

You may add other validation rules to any field using the rules() method:

TextInput::make('slug')->rules(['alpha_dash'])

A full list of validation rules may be found in the Laravel documentation.

Custom rules

You may use any custom validation rules as you would do in Laravel:

TextInput::make('slug')->rules([new Uppercase()])

You may also use closure rules:

TextInput::make('slug')->rules([
function () {
return function (string $attribute, $value, Closure $fail) {
if ($value === 'foo') {
$fail("The {$attribute} is invalid.");
}
};
},
])

Sending validation notiications

If you want to send a notification when validation error occurs, you may do so by using the onValidationError() method on your Livewire component:

use Filament\Notifications\Notification;
use Illuminate\Validation\ValidationException;
 
protected function onValidationError(ValidationException $exception): void
{
Notification::make()
->title($exception->getMessage())
->danger()
->send();
}

Alternatively, if you are using admin panel and you want this behaviour on all the pages, add this inside the boot() method of your AppServiceProvider:

use Filament\Notifications\Notification;
use Filament\Pages\Page;
use Illuminate\Validation\ValidationException;
 
Page::$reportValidationErrorUsing = function (ValidationException $exception) {
Notification::make()
->title($exception->getMessage())
->danger()
->send();
};
