First in administrator/com_booking/helpers/booking.php, second in administrator/com_booking/helpers/html.php but I think there is more code to edit. It solves the problem for me but you must know that my version of com_booking has been modified.

In fact the problem is the call to $current->toFormat('%W') which returns 0 for the first week of the year. We should get 1.

Ok sorry it's not good.

It makes further calculations wrong.

I correct it like this: in the function getWeekCalendar, I replace the line.

But then I have to change the function getWeekSelect replacing this line:

But I'm not sure it will not affect the rest of the code. An answer from ARTIO would be great.

Hello,

you have to check that it's the first week of the year. I had the problem with the function getWeekCalendar. The problem is with this line: $setting->year . '-W' . str_pad($setting->week, 2, '0', STR_PAD_LEFT). This doesn't work if $setting->week is equal to 0.
So you can do something like this:



And use $calc_date instead of $setting->year . '-W' . str_pad($setting->week, 2, '0', STR_PAD_LEFT) everywhere in the function. It seems to have solved the problem for me.

Happy new year !!!
