How to Customize Validation

Overriding existing validation

To override existing validation rules, you will have to copy the existing validation in your own bundle.

For example, to allow spaces in option codes, create the following file:

As you can see all the validation rules must be copied back in your file.

Adding new validation rules

To add new validation rules instead of replacing existing ones, simply create a new yml file in the config/validation directory of your bundle. The name of the file must be different from the already existing validation configuration files.

Product value validation

Product value validation uses different mechanisms than those described above. For more details about implementing your own rules, please read How to Use a Custom Entity as an Attribute Type.
