Question

在表单元素中，我编辑了错误消息：

$this->addElement('text', 'type', array(
    'label' => 'Type: ',
    'class' => 'form-control',
    'placeholder' => 'type',
    'required' => true,
    'validators' => array(
        array('validator' => 'StringLength', 'options' => array('min' => 3, 'max' => 10, 'messages' => array('stringLengthTooShort' => 'The type is too short.', 'stringLengthTooLong' => 'The type is too long.')))
        ,array('validator' => 'NotEmpty', 'options' => array('messages' => array('isEmpty' => 'Type is required.')))
    ),
));

问题是，如果我发送空表单，则会显示两条消息（类型太短+需要类型。）。但在这种情况下，我只需要显示NotEmpty错误消息而不是Stringlength（min length 3）错误消息。所以我需要在NotEmpty验证后验证minlength。感谢

修改：我已经尝试改变调用required和validators的不同位置以及它们的链的不同设置true / false（下一个代码），但是如果元素为空，它仍然显示两个错误消息

$this->addElement('text', 'type', array(
    'label' => 'Type: ',
    'class' => 'form-control',
    'placeholder' => 'type',

    'validators' => array(
        array('validator' => 'NotEmpty',true, 'options' => array('messages' => array('isEmpty' => 'Type is requiredDDDD.'))),
        array('validator' => 'StringLength',false, 'options' => array('min' => 3, 'max' => 10, 'messages' => array('stringLengthTooShort' => 'The type is too short.', 'stringLengthTooLong' => 'The type is too long.')))

    ),
    'required' => true,

));

Answer 1

您可以尝试这样的事情：

评论第二个验证器

$this->addElement('text', 'type', array(
    'label' => 'Type: ',
    'class' => 'form-control',
    'placeholder' => 'type',
    'required' => true,
    'validators' => array(
        //array('validator' => 'StringLength', 'options' => array('min' => 3, 'max' => 10, 'messages' => array('stringLengthTooShort' => 'The type is too short.', 'stringLengthTooLong' => 'The type is too long.'))),
        array('validator' => 'NotEmpty', 'options' => array('messages' => array('isEmpty' => 'Type is required.')))
    ),
));

并在isValid()函数中添加验证器：

public function isValid($data) {

    $etat_valid = parent::isValid($data);

    $error = $this->getElement('type')->getMessages();
    if (empty($error)){
        $validator = new Zend_Validate_StringLength(array( 
             'min' => 3, 
             'max' => 10, 
             'messages' => array('stringLengthTooShort' => 'The type is too short.', 
                                 'stringLengthTooLong' => 'The type is too long.')
                                                  )
                                           );

        $etat_valid_type = $validator->isValid($data['type']);
        if (!$etat_valid_type){
               $this->getElement('type')->addErrors($validator->getMessages());
        }
    }  

    return $etat_valid && $etat_valid_type;
 }

Answer 2

我上次评论的解决方案，如何为同一表格中的更多元素添加非空+不同的字符串长度验证：

public function isValid($data) {
    $etat_valid = parent::isValid($data);
    $elements = Array(Array('name', 4, 9), Array('type', 3, 10), Array('type2', 2, 12));

    for ($index = 0; $index < count($elements); $index++) {
        $error = $this->getElement($elements[$index][0])->getMessages();
        if (empty($error)) {
            $validator = new Zend_Validate_StringLength(array(
                'min' => $elements[$index][1],
                'max' => $elements[$index][2],
                    )
            );
            $validator->setMessages(array(
                Zend_Validate_StringLength::TOO_SHORT =>
                'Too short: min '.$elements[$index][1].' chars.',
                Zend_Validate_StringLength::TOO_LONG =>
                'Too long: max '.$elements[$index][2].' chars.'
            ));
            $etat_valid_type = $validator->isValid($data[$elements[$index][0]]);
            if (!$etat_valid_type) {
                $this->getElement($elements[$index][0])->addErrors($validator->getMessages());
            }
        }
    }
    return $etat_valid && $etat_valid_type;
}
