Invalid argument supplied for foreach() in ...

I have exactly the same problem - can't figure it out!

Same here, and if you google for it you find Drupal sites all over with it on their calendar pages ;-)

One page putting the error into the logs:

http://wsf2008.net/nl/view/calendar/all/all/all/2008/01/8

Invalid argument supplied for foreach() in /var/www/d53/includes/tablesort.inc on line 187.

Ack!! I can't see where this is coming from either. I'm not getting it on my installation. Does anyone getting this have the ability to use debug_backtrace to figure out what function in Claendar is triggering this?

Issues that look like duplicates are http://drupal.org/node/193916 and http://drupal.org/node/144404

I was getting this same set of errors until just now. I read the descriptions that are included when one adds an argument like "Calendar: Day" to the list. In the case of "Calendar: Day", the description reads "Filter by the calendar day (1-31). Place this argument after a 'Year' and a 'Month' argument." instructing you to place "Calendar: Month" in the second position in the list and "Calendar: Year" in the top position in the argument list.

So instead of my arguments being (in order)
Calendar: Day
Calendar: Month
Calendar: Year
Which resulted in the errors reported above.

I switched the order (as instructed by the descriptors) to
Calendar: Year
Calendar: Month
Calendar: Day

And the errors immediately went away and the view displays correctly.

I don't know if the site reporting problems have the arguments in the wrong order, but the code will definitely not work if they are in the wrong order. This is one of the complexities of the Calendar module -- Views is designed to have arguments that are completely independent and can be used in any order, but to get the right results in the Calendar they must work together and be in the right order.

It would be good to check if the people reporting the error have arguments in the right order -- they must be year/month/day order, and all three must be there for the code to work right.

Yes, mine are in the correct order %1,%2,%3 as Year, Month, Day and I still have the issue. Also curious is that the calendar is a day off (TZ issue.) coming from CiviCRM Events iCAL. I'm going to try applying a patch to the Date API.

I still have no idea where this might be coming from in the 1.7 version.

Hopefully this is fixed in the 5.2 version, which is not quite ready for an official release. You can see that release if you look for 'other releases' on the project page. Try it in a test environment, or be prepared to update it as bugs are found and fixed.

Reopen and change the version number if the problem still happens in 5.2.

I've tried to uninstall calendar and Date modules, then reinstall with the dev versions. I have the same error, but it seems to have gotten worse with the date update script (i have not yet reinstalled the calendar module.)

here is the error:

Re-opening. I've followed suggestion. updated to 5.x-2.dev

new error:

any ideas?

I'm getting this in 5.x-1.7:

I think this is the same as http://drupal.org/node/186875, which has a potential fix identified.
