README

Ever had problems with scheduled posts not being published? This plugin fixes that problem.

Configuration

Every minute the plugin looks for scheduled posts that lost their publish event. To keep that query fast, only posts scheduled within a window around the current time are considered: by default from one day into the past up to one hour into the future. Posts that were scheduled long before that window are considered stale and are left alone.

Use the achttienvijftien_missed_schedule_fixer_query_args filter to change the query. For example, to look a week into the past instead of a day:

add_filter(
	'achttienvijftien_missed_schedule_fixer_query_args',
	function ( $query_args ) {
		$query_args['date_query'][0]['after'] = wp_date( 'Y-m-d H:i:s', time() - WEEK_IN_SECONDS );

		return $query_args;
	}
);

Keep the query bounded by post_date. Removing the date query brings back the slow, unbounded behaviour this window is meant to avoid.
