Bic
===

This constraint is used to ensure that a value has the proper format of a
`Business Identifier Code (BIC)`_. BIC is an internationally agreed means to
uniquely identify both financial and non-financial institutions. You may also
check that the BIC's country code is the same as a given IBAN's one.

To use the Bic validator, apply it to a property on an object that
will contain a Business Identifier Code (BIC).

Available Options
-----------------

.. include:: /reference/constraints/_groups-option.rst.inc

``iban``
~~~~~~~~

**type**: ``string`` **default**: ``null``

An IBAN value to validate that its country code is the same as the BIC's one.

``ibanMessage``
~~~~~~~~~~~~~~~

**type**: ``string`` **default**: ``This Business Identifier Code (BIC) is not associated with IBAN {{ iban }}.``

The default message supplied when the value does not pass the combined BIC/IBAN check.

``ibanPropertyPath``
~~~~~~~~~~~~~~~~~~~~

**type**: ``string`` **default**: ``null``

It defines the object property whose value stores the IBAN used to check the BIC with.

For example, if you want to compare the ``$bic`` property of some object
with regard to the ``$iban`` property of the same object, use
``ibanPropertyPath="iban"`` in the comparison constraint of ``$bic``.

``message``
~~~~~~~~~~~

**type**: ``string`` **default**: ``This is not a valid Business Identifier Code (BIC).``

The default message supplied when the value does not pass the BIC check.

You can use the following parameters in this message:

===============  ==============================================================
Parameter        Description
===============  ==============================================================
``{{ value }}``  The current (invalid) BIC value
===============  ==============================================================
