Php 是否根据元素/字段值以Zend_形式进行验证？

让我们想象一下，我们有这样一个问题：“你是先生/夫人吗？” 根据答案值，我们将实施进一步的验证

比如说,， Mr>验证喜爱的车型 夫人：我最喜欢的花

是否可以覆盖

isValid

功能？

也许有一些最佳实践的例子？

我会编写一个自定义验证器，并使用提供的

$context

变量

一个简短的例子

控制器

class MyController extends Zend_Controller_Action {
    public function indexAction() {
        $form = new Application_Form_Gender();
        $this->view->form = $form;

        if ($this->getRequest()->isPost()) {
            if ($form->isValid($this->getRequest()->getPost())) {
                /*...*/
            }
        }
    }
}

class MyValidator extends Zend_Validate_Abstract {
    const ERROR = 'error';
    protected $_gender;
    protected $_messageTemplates = array(
        self::ERROR      => "Your gender is %gender%, so you have to enter something here",
    );
    protected $_messageVariables = array('gender' => '_gender');

    function __construct($gender) {
        $this->_gender = $gender;
    }

    function isValid( $value, $context = null ) {
        if (!isset($context['radio1'])) {
            return true;
        }
        if ($context['radio1'] != $this->_gender) {
            return true;
        }
        if (empty($context[sprintf('text%s', $this->_gender)])) {
            $this->_error(self::ERROR);
            return false;
        }
        return true;
    }
}

表格

class Application_Form_Gender extends Zend_Form {

    public function init()
    {
        $this->addElement('radio', 'radio1', array('multiOptions' => array('m' => 'male', 'w' => 'female')));
        $this->getElement('radio1')->isRequired(true);
        $this->getElement('radio1')->setAllowEmpty(false);

        $this->addElement('text', 'textm', array('label' => 'If you are male enter something here');
        $this->getElement('textm')->setAllowEmpty(false)->addValidator(new MyValidator('m'));

        $this->addElement('text', 'textf', array('label' => 'If you are female enter something here'));     
        $this->getElement('textf')->setAllowEmpty(false)->addValidator(new MyValidator('f'));

        $this->addElement('submit', 'submit');
    }

验证程序

class MyController extends Zend_Controller_Action {
    public function indexAction() {
        $form = new Application_Form_Gender();
        $this->view->form = $form;

        if ($this->getRequest()->isPost()) {
            if ($form->isValid($this->getRequest()->getPost())) {
                /*...*/
            }
        }
    }
}

class MyValidator extends Zend_Validate_Abstract {
    const ERROR = 'error';
    protected $_gender;
    protected $_messageTemplates = array(
        self::ERROR      => "Your gender is %gender%, so you have to enter something here",
    );
    protected $_messageVariables = array('gender' => '_gender');

    function __construct($gender) {
        $this->_gender = $gender;
    }

    function isValid( $value, $context = null ) {
        if (!isset($context['radio1'])) {
            return true;
        }
        if ($context['radio1'] != $this->_gender) {
            return true;
        }
        if (empty($context[sprintf('text%s', $this->_gender)])) {
            $this->_error(self::ERROR);
            return false;
        }
        return true;
    }
}

正如您在本例中所看到的，在

$form->isValid（）

中提供的所有数据都是通过

$context

变量提供的，您可以使用该变量执行任何检查。

我发现重写

isValid

对我来说最方便。您还可以尝试使用

$context

第二个参数的自定义验证器。但是它有点麻烦，因为您无法直接访问表单，这有时可能很方便/需要。我发现重写
