csv

Description

Wpart responsible for entering CSV (Common Separated Values) data. During the validation phase data is split by delimiter and passed to the lower level (basic elements) validators. All elements of the field must be of the same type. The type of the elements is described by type parameter.

For example, if we want to add a new attribute describing our model, let's say tags, that will hold the list of the same data, we can use wpart_csv for that. The data retrieved from the form will be tokenized and stored in the database as a list of values.

The rendered widget is <input type="text" ... />.
