Development - Hokoku (Zenbu Export) for EE3

Development documentation

This documentation is for the EE2 version of Hokoku (1.x)

By default, Hokoku exports data as it displayed in the Zenbu module, but with HTML markup stripped out. Starting with Hokoku 1.2.0, export options can be added to modify how data is exported based on the data presented by Zenbu.

Hokoku first looks for Hokoku functions in the third-party’s fieldtype file (ft.field.php). If Hokoku functions are not found, Hokoku looks for fieldtype support files corresponding to a fieldtype in the hokoku/fieldtypes folder. As a final fallback, if Hokoku functions are still not found, the exported data will be the data displaed by Zenbu, with HTML markup stripped.
