Hello all,

this warning probably has no effect on functionality. But if you want to repair it, find that file and line from error report and modify this code:

foreach($data as $val)
{
$array[$val['key']] = $val['value'];
}

to:

if ($data){
foreach($data as $val)
{
$array[$val['key']] = $val['value'];
}
}

Was that helpful?

And to berndholtz:
Symbols to select time and date are there. I found only 1 problem and it is probably in javascript creating new price option row. All fields for dates and times are shifted to the left. You can still create new price settings and after save, everything is fine.
I will try to look on this problem deeply and send you a solution for javascript problem.

Solution for second bug should be easy too.
Find this file: components/com_booking/assets/js/view-subject.js and check line 389.

There should be this code:
ACommon.createCalendar(children[10], 'priceDateUp#', 'price-date_up[]');
ACommon.createCalendar(children[11], 'priceDateDown#', 'price-date_down[]');
/* append and setup time pickers */
ACommon.createTimePicker(children[12], 'price-time_up[]');
ACommon.createTimePicker(children[13], 'price-time_down[]');


Modify all rows and increase all numbers by 1. Finally there will be these numbers: 11, 12, 13 and 14.
