Flexical

Flexical is a PHP/MySQL calendar forked from phpEventCalendar by Isaac McGowan, and available under the GPL. It works great right now, and there are plans for some serious improvements, including icalendar import/export and repeating events. Don't hold your breath, it will take a while. The only reason development continues is because online portal calendars (like Google Calendar) don't provide the sort of display one needs to print out monthly event calendars.

Downloads

Some distribution archives can be found at the web site where Flexical is in production use. They are inevitably outdated, since releases are posted sporadically. The newest updates can be obtained via the gitweb interface at git.christfor.us. The bleeding edge (main branch) probably won't work, but the in_use branch ought to. Sorry, documentation is parse.

Demo

To see it in action, visit the production site. There's also a virgin demo install you can play with. Though it's not nearly as customized, you can log in as a privileged user and play with it.

Features

• Calendar tab, showing the classic landscape month calendar, weekdays ordered Sunday through Saturday, with a basic interface for selecting a different month and year, or navigating to the next, previous, and current (present-day) month. This may be displayed using a legacy HTML table or the CSS-based "display: table" property. Internet Explorer can only handle the former, but does display the calendar correctly when legacy tables are used.
• Event List tab, showing a tabular listing of events that fall on a specified date and a number of time units (days, weeks, months, years) after. It also allows navigation to the next or previous time span, or to the current date as a starting point. Events within dates are listed chronologically.
• Categorization of events. The display of event and category names can be tweaked with CSS, so that an event's category may be recognized at a glance. (See css/custom.css for examples.) Categories can be selected (or not) for the display of their events, and some categories can be designated as "hidden," so that casual users won't ever see them. Whole categories can be deleted with all their events at once, and their names can be changed by an administrator.
• User levels that distinguish between unauthenicated viewers, privileged viewers, event editors, and administrators. Popup windows are avoided when possible, and links are provided with displayed events, for privileged users, so that the effort required to create, modify, or delete events is minimal.
• Instead of offering repeating events at this point, we have the ability to copy events in a sophisticated way, repeating copies by day, week, month-by-day, month-by-date, and year.
• In addition to selection by category and by date range, events may also be filtered by title, description, and/or time, so that only matching events are displayed. This also allows privileged users to set those things for a number of events that match any required date range, category, and filter setting. The title and description filters are regular expressions, which provides great flexibility.
• Administrators are able to backup and restore the calendar database through the web.
