Magic Data Forms extends Magic Data to work with forms and form results.
Magic Data Forms does not include a forms block of its own. Magic Data Forms interfaces to existing forms blocks, such as the core Form block.
Use a form block to build an interface where users enter information, then have complete control over where, how and when you display it.
The forms block interface is open and configurable to plug in interfaces to other forms packages or indeed any tabular data. For example, Magic Data Forms CSV Interface.
Please read the documentation for details.
From version 1.3 this addon is compatible with php7. To update a site to php7 you will need to make core updates (at time of writing only on github and not released). You will also need to ensure that other addon packages are php7 compatible.
