Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Greetings. By using the module I realize that this returns a warning of an array is not passed correctly to a php function (array_filter).
This code is as follows.
foreach ($items as $key => $val) (
if ($val && (count (array_filter ($val)) < $min_selections)) (
$Errors [$key] = t ('Please select at least options for% num% item', array ('%num' => $min_selections, '%item' => $components[$key]['name'] ));
)
)
As you can see the variable $ val is not an array. The array is the variable $ items. The above code is around line 211 of file webform_validation.validators.inc.
Suggest that the argument of the function array_filter is modified $val variable by the variable $items
Sorry by my english, I am from Venezuela and my english is not very good.
Bye.

quicksketchThis bug is in Webform Validation module, not Webform core.

svendecabooterCan you give more information on the specifics of your setup?
Did you change anything in the code, or did you implement any webform_validation hook?
By default, the minimum selection validation rule only applies to 'select' form components.
When the validation is run, $key is the component ID, and $val is an error of submitted entries for your 'select' form component.
Since each 'select' form component needs at least one option set, this will always be an array. I cannot reproduce your case where it isn't an array.
As an extra check i'm changing
if ($val && (count(array_filter($val)) < $min_selections)) {to
if (is_array($val) && (count(array_filter($val)) < $min_selections)) {.Can you get the latest version of the module from CVS with this change, and see if that fixes your problem?
