Zend Form 2 multiselect field is empty after validation


Zend Form 2 multiselect field is empty after validation

will help you When you specify multiple in attributes, Zend\Form and Zend\InputFilter add []after the name. You should not do it yourself otherwise, in the html code, the element appears under the name author[][] and the setData method don't match. To see it, replace required by true and look at the html code of the form.
code :
$this->add([
        'name' => 'author',
        'attributes' => [
            'class' => 'form-control',
            'data-placeholder' => 'Author',
            'multiple' => 'multiple',
            'placeholder' => 'Author',
        ],
        'required' => false,
        'type'       => \Zend\Form\Element\Select::class,
        'options' => [
            'value_options' => [
                'check1' => 'check1',
                'check2' => 'check2',
            ],
        ],
    ]);

    $this->myInputFilter->add([
        'filters' => [],
        'name' => 'author',
        'required' => false,
        'validators' => [],
    ]);

hop of those help? Override the isValid() and setDefaults() methods in your Form class to populate the city element when the country element is set.
code :
function isValid($data) {
    if (isset($data['country'])) {
        $this->populateCity($data['country']);
    }
    return parent::isValid($data);
}

function setDefault($name, $value) {
    if ('country' === $value) {
        $this->populateCity($value);
    }
    return parent::setDefault($name, $value);
}

wish of those help if you set 'required' => true Zend_Form append in automatic the validator NotEmpty to input textarea. The error messages are displayed only if you execute the method of the isValid() Form. Then calls the isValid the point that you feel most appropriate.
