Enforce Address Postcode Validation

LFS Version requirement: v11.16 or later

The delivery address form in Limio For Salesforce validates the Postal/Zip Code field value against a Regular Expression from the Custom Metadata Type config.

The validation occurs in the Delivery Contact component, in the Delivery Postal Code field, and depends on the Country being selected.

Because the post code validation depends on the country being selected, any given post code is considered invalid as long as country field is not populated

NOTE: if the setting is left blank and no regular expression is specified, any post code is considered as valid for the country.

The form supports further customisation for adding a custom validation message specific to each country. In this case the custom message will appear as placeholder to the delivery postal code, to help the user inputting the code in a valid format from the start.

If the format used is still invalid against the regex specified, the same validation message will appear as input field error message:

In order to update the regular expression and the corresponding validation message, follow the instructions below:

1. In the Setup search box, look for the Custom Metadata Types and click 'Manage Records' on the Region type.

2. Find a region of interest and click 'Edit'.

3. Find the Address Validation field and populate a 'zip' property of the object inside with the relevant Regular Expression

4. In the same Address Validation filed, add (or edit) the property 'invalid_code_msg' with the relevant message

5. Save the record.

As an example, the Address Validation can be populated as follows for United Kingdom post codes
