php - Symfony 1.4 - 强制 symfony 在到达后验证者之前停止执行

Question

我在 symfony 1.4 中创建了一个丢失的密码表单，并且一直遇到一个问题，即即使小部件约束失败，也会调用 post 验证器。

片段：

$this->validatorSchema['email_address'] = new sfValidatorEmail(
    array(
        'max_length'    => 254,  // http://www.rfc-editor.org/errata_search.php?rfc=3696&eid=1690
        'min_length'    => 4,
        'required'      => true,
        'trim'          => true
    ),
    array(
        'invalid'       => 'Email address entered is malformed',
        'max_length'    => 'Email Address cannot contain more than %max_length% characters',
        'min_length'    => 'Email Address must be at least %min_length% characters',
        'required'      => 'Please enter an email address'
    )
);

$this->mergePostValidator(new sfValidatorCallback(array('callback' => array($this, 'emailValidate'))));
$this->mergePostValidator(new sfValidatorCallback(array('callback' => array($this, 'throttleCheck'))));

问题是“emailValidate”回调假定已输入格式正确的电子邮件地址，例如 a@b.com，但如果我输入垃圾，例如“fdadfaa”，表单仍会继续尝试执行 post 验证器，当它不应该。如果数据不好，就没有理由发出查询。

我找到了一个“halt_on_error”标志，它可以传递给模式验证器构造函数，但对我不起作用。还有人过这座桥吗？

Symfony 是一个疯狂的旅程......能够使用它来让它工作：

$this->validatorSchema['email_address'] = new sfValidatorAnd(
    array(
        new sfValidatorEmail(
            array(
                'max_length'    => 254,  // http://www.rfc-editor.org/errata_search.php?rfc=3696&eid=1690
                'min_length'    => 4,
                'required'      => true,
                'trim'          => true
            ),
            array(
                'invalid'       => 'Email address entered is malformed',
                'max_length'    => 'Email Address cannot contain more than %max_length% characters',
                'min_length'    => 'Email Address must be at least %min_length% characters'                        
            )
        ),
        new sfValidatorCallback(array('callback' => array($this, 'emailValidate'))),
        new sfValidatorCallback(array('callback' => array($this, 'throttleCheck')))
    ),
    array('halt_on_error' => true),
    array('required' => 'Please enter an email address')
);

这里唯一的问题是 postValidators 直接绑定到电子邮件字段，因此您必须将任何引用从 更改$values['email']为$values。但它似乎确实可以在点击后验证器之前停止执行流程。
