The MoneyBundle provides support for making a number of comparisons for Money\Money instances using the Symfony Validator component.

All constraints support either a Money\Money instance or a scalar value (string/int/float) which can be parsed into a Money\Money instance.

Validates that a value is equal to another value as defined in the options. To validate that a value is not equal, see MoneyNotEqualTo.

Validates that a value is not equal to another value as defined in the options. To validate that a value is equal, see MoneyEqualTo.

Validates that a value is less than another value as defined in the options. To validate that a value is less than or equal to another value, see MoneyLessThanOrEqual. To validate a value is greater than another value, see MoneyGreaterThan.

Validates that a value is less than or equal to another value as defined in the options. To validate that a value is less than another value, see MoneyLessThan.

Validates that a value is greater than another value as defined in the options. To validate that a value is greater than or equal to another value, see MoneyGreaterThanOrEqual. To validate a value is less than another value, see MoneyLessThan.

Validates that a value is greater than or equal to another value as defined in the options. To validate that a value is greater than another value, see MoneyGreaterThan.

The constraints support the following extra options, similar to the comparison constraints provided by the Validator component:

• groups - Defines the validation group(s) this constraint belongs to
• message - This is the message that will be shown if the value fails the validation check; messages have the following parameters available:
  • {{ compared_value }} - The value being compared to
  • {{ compared_value_type }} - The expected value type
  • {{ value }} - The current (invalid) value
• payload - This option can be used to attach arbitrary domain-specific data to a constraint, it is not used by the Validator component, but its processing is completely up to you
• propertyPath - Defines the object property whose value is used to make the comparison
• value - This option is required; it defines the value to compare to, this should be a Money\Money instance or a scalar value (string/int/float) that can be parsed into a Money\Money instance

When used alongside the Symfony Form component, the constraints can be used with your forms to validate your data.
