Provides an MultipleDatePickerField for managing and saving a string of multiple dates into a text field. Integrates jQuery MDP plugin, a plugin that enables jQuery UI calendar to manage multiple dates. See demo of the javascript interface & configuration options.

• Michael van Schaik <mic (at) restruct (dot) nl>

• SilverStripe 3.0 or newer

• Builds on silverstripe DateField (with Text field), same config & localisation supported (specific locales may need some further testing)
• Integrates MDP 1.6.3, a plugin that enables jQuery UI calendar to manage multiple dates
• Allows setting custom date separator (default: ", "), more Multidatepicker-specific configuration options can easily be added.
• TODO(!): I could use some help with the silverstripe config system for this module; I'm now using ($this->getConfig('separator') ? $this->getConfig('separator') : ', ') in order to provide a callback for the date separator because sometimes custom configuration values don't seem to load.
• TODO: Saving into many_many relation (currently only textfield supported)
• TODO: Full unit test coverage
• TODO: Validation (currently commented out)
