*****************

.[perex]
You can change the default [form error messages|validation] in the configuration.

```neon
forms:
	messages:
		Equal: 'Please enter %s.'
		NotEqual: 'This value should not be %s.'
		Filled: 'This field is required.'
		Blank: 'This field should be blank.'
		MinLength: 'Please enter at least %d characters.'
		MaxLength: 'Please enter no more than %d characters.'
		Length: 'Please enter a value between %d and %d characters long.'
		Email: 'Please enter a valid email address.'
		URL: 'Please enter a valid URL.'
		Integer: 'Please enter a valid integer.'
		Float: 'Please enter a valid number.'
		Min: 'Please enter a value greater than or equal to %d.'
		Max: 'Please enter a value less than or equal to %d.'
		Range: 'Please enter a value between %d and %d.'
		MaxFileSize: 'The size of the uploaded file can be up to %d bytes.'
		MaxPostSize: 'The uploaded data exceeds the limit of %d bytes.'
		MimeType: 'The uploaded file is not in the expected format.'
		Image: 'The uploaded file must be image in format JPEG, GIF, PNG, WebP or AVIF.'
		Nette\Forms\Controls\SelectBox::Valid: 'Please select a valid option.'
		Nette\Forms\Controls\UploadControl::Valid: 'An error occurred during file upload.'
		Nette\Forms\Controls\CsrfProtection::Protection: 'Your session has expired. Please return to the home page and try again.'
```

If you are not using the whole framework and therefore not even the configuration files, you can change the default error messages directly in the `Nette\Forms\Validator::$messages` field.
