What Is Serialization?

In very rare cases, some themes store multiple data points in a single field. Themes shouldn’t do this. It’s not nice, and the practice is generally frowned upon, but it still happens. These fields are often called Serialized Fields.

To add a serialized meta/custom field, enter the meta/custom field name, then click the Multiple values? checkbox and define what’s imported.

The Serialize feature generates an array with the key => value pairs you specify, and then returns the serialized value of the array.

This option allows you to add unlimited serialized data.
