This is a pre-release please do not use in production.

FieldtypeRecurringDates

Fieldtype and Inputfield for definining recurring dates according to RFC-RFC 5545 and the awesome library php-rrule

Installation

composer require elabx/fieldtype-recurring-dates

Make sure to install both FieldtyeRecurringDates and AlpineJS modules. Additionally you may install RecurringDatesFinder for search operations.

Or download through the processwire modules directory.

This module will save the RRules occurrences in the database to be queried later.

Find pages with fields

Use date values valid for date selectors.

$pages->find('recurring_meetings=>today')

Finding occurrences

You can use the module included in this same package to find the rules occurrences:

$start and $end value are any acceptable value for $datetime

$finder = $modules->get('ReccurringDatesFinder')
$output = $finder->find(
     // from date 
    'today', 
    // to date
    '+30 days', 
    $selector, [
        'fields' => [ // Will find event occurrences in fields specified in this array 
            'recurring_meetings',
            'recurring_events'
        ]
    ]

This method will return the SQL UNION result of specified fields.

You can also hook into getRecurringFieldQueries() to add queries that will get added to the final UNION query.
