I was asked by a member of the MODx-community, if it is possibly to count the children of more than one parent. So I tried to rewrite this snippet. But not being a programmer I need some help:

Thisis how I started:

$parentId = explode(",",$parentId);

foreach ($parentId as $value) {

  $child = count($modx->getDocumentChildren($value, 1, 0,'id'));

}

$partentId would be an comma seperated list of parents ID´s from the snippet call.

Now I wanted to have something like

  echo array_sum($child);

but $child will not return an array but simply the numbers of the children written one after the other without any delimiter.

Any ideas?

Thank you

Dimmy, thank you for the fast answer.

I´m not sure what "child +" will do but that doesn’t seem to work.

If you want child to be an array you need to let it know, it thinks it is a string.

try adding $child = array() before the foreach loop

And change the code to

$child[] = count($modx->getDocumentChildren($value, 1, 0,'id'));

I´m not sure what "child +" will do but that doesn’t seem to work.

This should return the total of all the children since it adds the value of each pass in the foreach loop. This would eliminate the array_sum() since you would already have the total value.
