How to sum calc element in repeating group?

[marcelhavlik]

Hello guys, I have already tried total element, but it shows the correct result for only one second and then only 0 (zero). Could you please help me with this issue?

I found also a solution with calc element with code below, but it works only for 2 and more records in repeating group.

array_sum($data['table___element_raw'])

Thank you

... but it works only for 2 and more records in repeating group

... indicating that it's not an array if there's only a single record. Means you want to first check if it's an array (then use your code), else return the single value only.

Thank you for your reply, but could you please send me an example? Thank you

if (is_array($foo)) {
    // do something with the array
} else {
    // do something else
}

}

Thank you!! Do you know how to enable this calculation (of calc element) via AJAX? Now if I enable AJAX, I will get 0, but after save is total correct.
