TYPO3 Core

Hi,

when setting TCA display condition e.g like this: 'displayCond' => 'FIELD:type:IN:1,2,3,4' the condition fails if e.g. the field has the value array(0=>2).

@see TYPO3\CMS\Backend\Form\FormDataProvider\EvaluateDisplayConditions::matchFieldCondition

This could solve the problem:

            case 'IN':
            case '!IN':
            case '=':
            case '!=':
                if (is_array($fieldValue)) {
                    foreach (GeneralUtility::trimExplode(',', $operand) as $operandItem) {
                        $result = in_array($operandItem, $fieldValue);
                        if ($result === true) {
                            break;
                        }
                    }
                } else {
                    $result = GeneralUtility::inList($operand, $fieldValue);
                }
//                $result = is_array($fieldValue)
//                    ? in_array($operand, $fieldValue)
//                    : GeneralUtility::inList($operand, $fieldValue);
                if ($operator[0] === '!') {
                    $result = !$result;
                }
                break;
