Projects / WebCalendar


WebCalendar is a Web-based calendar application that can be configured as a single-user calendar, a multi-user calendar for groups of users, or as an event calendar viewable by visitors. WebCalendar requires a database such as MySQL, Oracle, PostgreSQL, MS SQL Server, ODBC, or Interbase. Features include email reminders, iCal/vCal import/export, remote subscriptions for Sunbird or Apple iCal, LDAP and NIS support, and translations for 29 languages.

            Hello all,

            I just installed webcalendar via my hosting service's one-click install. I'm wanting to modify it style-wise to fit the look of the website to which it is now part.

            1. Make the liquid layout fixed and centered. I changed $tableWidth to 760px, and that worked, but the table is now left-justified. I'd like to center it on the page.

            2. This is for public viewing only, so I do not want the GO TO or CURRENT USER menus that appear at the bottom when the top menu bar is deactivated.

            3. I'd like to be able to center the optional header text and change the text format.

            4. I'd also like to change the text size of the month.

            5. I'd also like to remove the category drop-down box, and the lower month, week and year drop downs as well.

            6. How to make the 'Public Access' text below the month say something else?

            I appreciate the sheer amount of work this webcalendar project took. Being straight PHP it's harder for an intermediate user such as myself to tweak it. Any and all help would be greatly appreciated.

            Yes, you can turn public event submissions on and off. We have also added CAPTCHA for public event submissions to cut down on link spamming.

            Is it possible to have a calendar that is viewable by the public but not update-able by the public so that the entries are only created by specific individuals?

            Hey, these are great tips! A little bit of info goes a long way. I will have to implement a few of these in my blog for sure.
