Version Control For ProcessWire CMS/CMF
Version Control Module For ProcessWire CMS/CMF. Copyright (c) 2013-2016 Teppo Koivula
This module uses hooks provided by ProcessWire to catch page edits and stores history data in a series of custom database tables, so that it can be later retrieved, reviewed, and restored.
Note that at module settings you can define which specific fieldtypes and fields to track and for which templates tracking values should be enabled. Right out of the box tracking is disabled for all templates and fields.
While editing a page with version control enabled, revision toggle (link which opens list of previous revisions) is shown for fields with earlier revisions available. From this list user can select a revision and rollback value of the field to that specific revision.
Supported fieldtypes and inputfields
All native ProcessWire fieldtypes and inputfields, apart from those that either don't directly store values at all (repeaters fields, fieldsets) or only store hashed values (password), should be supported by the time of this writing:
- Text (regular and multi-language)
- Textarea (regular and multi-language)
- Page Title (regular and multi-language)
If a specific fieldtype isn't listed here, it doesn't necessarily mean that it's not supported; it just hasn't been tested yet. If you know a fieldtype that works properly with this module but isn't included here, please inform the author of this module via GitHub.
You can enable support for any installed fieldtypes locally by modifying the "Compatible fieldtypes" setting, which can be found under "Advanced Settings" in module configuration screen.
Following inputfields are confirmed to be supported:
- CKEditor (regular and inline mode)
- Text (+ other inputfields using
<input>HTML element, such as Email)
- Textarea (+ other inputfields using regular
Please note that this module requires ProcessWire 2.4.1 or a later version. If you're still running an earlier version of ProcessWire and would like to have a similar feature, please take a look at the Version Control for Text Fields module: https://github.com/teppokoivula/VersionControlForTextFields.
Copy (or clone with git) VersionControl folder to /site/modules/, go to Admin > Modules, hit "Check for new modules" and install Version Control. Supporting modules Process Version Control and Page Snapshot are installed automatically.
After installing this module you need to configure it before anything really starts happening. Most configuration options (essentially templates and fields this module is switched on for) can be found from Admin > Modules > Version Control (module config.) Minor settings can be found from related Process modules config: Admin > Modules > Process Version Control.
