Symfony 4 was released on November 30th.
Update now to the best Symfony ever!

You are browsing the Symfony 4 documentation, which changes significantly from Symfony 3.x. If your app doesn't use Symfony 4 yet, browse the Symfony 3.4 documentation.

Basic Usage

To verify that the "height" field of a class is between "120" and "180", you might add the following:

Date Ranges

This constraint can be used to compare DateTime objects against date ranges. The minimum and maximum date of the range should be given as any date string accepted by the DateTime constructor. For example, you could check that a date must lie within the current year like this:

    }
    

Be aware that PHP will use the server's configured timezone to interpret these dates. If you want to fix the timezone, append it to the date string:

The DateTime class also accepts relative dates or times. For example, you can check that a delivery date starts within the next five hours like this:

Options

min

type: integer

This required option is the "min" value. Validation will fail if the given value is less than this min value.

max

type: integer

This required option is the "max" value. Validation will fail if the given value is greater than this max value.

minMessage

type: string default: This value should be {{ limit }} or more.

The message that will be shown if the underlying value is less than the min option.

maxMessage

type: string default: This value should be {{ limit }} or less.

The message that will be shown if the underlying value is more than the max option.

invalidMessage

type: string default: This value should be a valid number.

The message that will be shown if the underlying value is not a number (per the is_numeric PHP function).

payload

type: mixed default: null

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
