Example

fields:

Decimals

Decimals can be used by adding the step option.

fields:
  price:

Minimum and maximum value

The min and max options define which numbers can be selected with the browser-specific up/down arrows and are also used to validate the input.

fields:
  temperature:
    label: Temperature
    type: number
    min: -50
    max: 250

before & after values

The number field can show additional text before or after the input. This is great when you need a price field for example:

fields:
  price:
    label: Price
    type: number
    min: 0
    before: €

How to use in templates/snippets

If your number field contains only integers, you can convert the value to a proper integer with the toInt() field method:

<?= $page->numberfield()->toInt() ?>

For floating value, use the toFloat() method:

<?= $page->numberfield()->toFloat() ?>
