Calendar 1.2.3 Released

Calendar version 1.2.3 has been released. You can download it from WordPress or from my own site. Thanks to all who helped with testing and especially to those who offered solutions to discovered issues.

This release sees a whole raft of important bug fixes, if you have a minor issue with your current install it will almost certainly be fixed in this version.

In addition to fixes, a number of enhancements have been added

  • Full support for WordPress 3.0
  • Recurring events by weekday (ie. 3rd Sunday of every month)
  • Ability to list today’s and upcoming events on posts/pages using tags

Hope you continue to enjoy using Calendar!

    There is a problem with version 1.2.3 … on my site at, when u mouse over on the event dates, the title & color is overlapping. Happened on my other site as well. I’m using wp 3

    Thank you so much for the calendar update. I appreciate it. There is one issue, however, that I have with the changes. I like to use category colors, but I do not like the category colors to display in the sidebar under current and upcoming events. It adversely effects the look of the site.

    How do I go about keeping category colors for the full calendar view and for mouse-overs, but eliminating them from the sidebar? I can’t find an option for that.

    hey there, thanks for helping me resolve my issue on installing your plug in, your advice did do the trick. i found the calendar settings within settings and set everything up to. my problem now is that i dont see the calendar.

    i did had the widgets upcoming events and today’s events. i did add the calendar widget but it only showed my posting from yesterday, it didnt show any of the dates in the future or today’s event. i took the calendar widget off and i am looking around your forum trying to figure this out.


    what am i doing wrong?

    does not have the Recurring events by weekday (ie. 3rd Sunday of every month) option in the Admin Control Panel.

    Re-Installed 3 times.

    Also hides times on roll over even after resetting to default options .

    Going back to old version

    Trying to solve some problems with my WP install and running in debug, I get some warnings thrown out for your plugin:

    Notice: register_sidebar_widget is deprecated since version 2.8! Use wp_register_sidebar_widget() instead.

    Notice: register_widget_control is deprecated since version 2.8! Use wp_register_widget_control() instead.

    I changed these functions to use the new versions and it works, but the args have changed for them, so you might need to fix.

    Also encountered a problem with load_plugin_textdomain call for which the args have changed.

    If I use the following it stops complaining:

    $plugin_dir = dirname( plugin_basename( __FILE__ ));
    load_plugin_textdomain( ‘calendar’, false, $plugin_dir);

    I had a question. I’m having trouble trying to remove the “time” from each event. When I remove it from the control panel i get an “all day”. is it possible to remove that?

    Thanks for the information Glen, I’ll work on resolving those issues.

    Toni, please ask your questions in the forums

    Hi there! I’ve been sitting for 3 evenings trying to put your plugin back to it’s normal working state (with all those glitches and annoying misstylings) and filnally got it working PERFECTLY!.

    I’ve posted an archive with my update to your forum:

  12. Ionut Staicu Said,

    August 5, 2010 @ 1:37 pm

    Thanks for this nice plugin dude!

    Quick idea for next version: make semantic html markup. Br is kinda useless 😉

    I used 1.2.2 and today, after I updated, I started to find & replace.

    Would be great if all structure will be customizable via wp-admin 🙂

    Oh, and maybe you can do a little optimization. 400+ queries/page on a medium traffic site are not too server friendly 😉

    I think there is an error with the table creation on the plugin, the error is with the calendar table:

    ERROR 1101 (42000): BLOB/TEXT column ‘event_link’ can’t have a default value

    I changed this line in the calendar table: event_link TEXT ,

    An calendar worked OK

    Thanks for the great calendar plug-in. I have three requests… first wondering if you can incorporate and option where we can choose between a 12-hour clock and the current 24-hour clock. Second, is it possible to have a calender layout option where the weekends are in the traditional layout where they bookend the weekdays? And third request, when adding the optional link to an event, can the link go to a new tab or window without leaving the current page?

  18. Anna Said,

    Is there a way that I can allow the public to update the calendar from my website?

  19. N21LV Said,

    August 25, 2010 @ 6:31 pm

    Anna, did you try to configure the Calendar? There’s an option in Calendar Config which allows users to create/edit events. It’s smth like “Lowest access level to create/edit events”. Just specify an access level (Reader, Contributor, etc.) and registered users of your blog will be able to manage your calendar.

    I you mean overlapping in calendar view, then it’s managed in my fix. The link is some comments above.

    Hi Kieran, thanks bunches for this! You saved me LOTS of time. I’m pulling the calendar from the wordpress side of our site and using it in a standard php page. In action:

    Still working on styling it up a bit. I have one question at the moment. I’d like to use this calendar for our events as well as our driving schedule. Is there a way to implement a separate calendar/db so that we could show our events without having the driving schedule show up? Thanks again!

  23. Joco1114 Said,

    @N21LV: I’ve downloaded the fix, but it didnt solve my problem in the sidebar:

  24. N21LV Said,

    August 30, 2010 @ 9:53 pm

    You have something terribly wrong with your style. Try to tinker with that. Look for Z-indexes of other elements, the tooltip needs to have the highest possible value to overlap other elements. What seems to me is that the tooltip is being drawn not over a whole page, but over an element of a sidebar. So, if you solve that problem by somehow positioning the tooltip over the whole page, you might get some results. Howerver, if you don’t feel yourself skillful in web-design.. you may need to change the style or look for another plugin.

    I’m curious as to why the calendar has no daily reoccurring option. For example, if I’m holding a 3-day event that runs Friday-Saturday-Sunday, I have to make 3 separate entries. It has weekly and monthly – a daily would be nice too.

    Just a thought! It’s a nice plugin, works well except for this one item.

  26. N21LV Said,

    September 9, 2010 @ 5:02 pm

    Actually, it is not clear what do you really need. You can easily set a 3-day event by entering Friday as a start date and Sunday as an end date and get what you want. The only such issue that this plugin has is that more-than-one-day events share their starting time. To set an event which starts at 1100 at 1st day and lasts three days you need to set 2 separate events – one 1-day event starting at 1100 at the 1st day, and second 2-day event which starts on 2nd day with no starting time.

    Thanks, I’ll try that!

    Since I updated my calendar, when u mouse over on the event dates, the title & color is overlapping and not justified. Any idea why and can I go back to the old version which worked fine? I’m using wordpress 3.01

  29. Lucs Said,

    October 1, 2010 @ 3:31 pm

    Dear Kieran,
    I installed your plugin but came to a problem. When I try to enter a new event, I get the following error message: “Error: An event with the details you submitted could not be found in the database. This may indicate a problem with your database or the way in which it is configured.”
    Everything else seem to work normally. I also took a peek in my mysql log but there is no error or failed connection attempt listed.
    I am running wordpress on a IIS server.
    Is there any ideas about what may be the cause of the problem?

    Hi Kieran,

    The calendar is great! Thanks for making it.
    Two thoughts:

    1. Is there (or can there be) a way to print out the month with the daily details shown? I want to use it for my fire stations website, but we need to be able to print out the calendar regularly.

    2. I tried desperately to sign up for the calendar forum, but couldn’t get past the captcha (and I’m a real person!). Please take a look at that and consider using one that’s not so hard to make out.

    I used the Calendar on my Side but I can’t display the Todays Event on the Sidebar WHY.

    Hi. I’m having the same problems as Ionut Staicu above – 550+ queries is quite much for a calendar plugin I say.

    It also adds about .5 of a second to the execution of my site

    I cannot see, what all these queries is about? Get all database info in one query, and then use php or javascript to structure it. It is not good to create a new query for every thing you need posted on the page.

    This is the best calendar plugin I have found, but I am sorry to say, it needs a rewrite (and I do not have the time to do it ;D)
    I hope you have?

    Best regards
    Svend K

    Thanks for the plugin. I can’t seem to go to the full calendar view. How can I make a page aobut it? There are no links to the full page calendar. Is it because of my theme? My current theme is Motion by 85ideas. Anxiously waiting for the answer. Thanks again.

    Full-page calendar may be shown by creating a new page in your Dashboard and typing the word {CALENDAR}. Read the manual.

    Like Kristina up above, I am also having problems with the sidebar widget. The months are not jumping properly and the dates are not displaying events. The Page calendar is working perfectly.
