$form = new Zend_Form();

$mockDate = new Zend_Form_Element_Text('mock');

$mockDate->addValidator(???????);

$form->addElements(array($mockDate));

$result = $form->isValid();

if ($result) echo "YES!!!";
else echo "NO!!!";

假设元素采用日期格式。如何确定给定的日期大于或等于今天?

class My_Validate_DateGreaterThanToday extends Zend_Validate_Abstract
{
    const DATE_INVALID = 'dateInvalid';

    protected $_messageTemplates = array(
        self::DATE_INVALID => "'%value%' is not greater than or equal today"
    );

    public function isValid($value)
    {
        $this->_setValue($value);

        $today = date('Y-m-d');

        // expecting $value to be YYYY-MM-DD
        if ($value < $today) {
            $this->_error(self::DATE_INVALID);
            return false;
        }

        return true;
    }
}

并将其添加到元素中:

$mockDate->addValidator(new My_Validate_DateGreaterThanToday());

Zend_Date 用于日期本地化和其他好处。

要创建自定义验证,请查看 writing validators 来自Zends手册。

    if(!$this->inputFilter){
        $inputFilter = new InputFilter();
        $inputFilter->add(array(
            'name' => 'mock',
            'validators' => array(
                array('name' => 'Date'),
                array(
                    'name' => 'GreaterThan',
                    'options' => array(
                        'min' => date('Y-m-d'),
                    ),
                ),
            ),
        ));
        $this->inputFilter = $inputFilter;
    }
    return $this->inputFilter;
}
