Question

我使用zend框架和zend表单和验证器DIGIT，如下所示：

    $ZV_Digit=new Zend_Validate_Digits();
    $credit = new Zend_Form_Element_Text('credit');
    $credit->setLabel('current credit');
    $credit->setValidators(array($ZV_Digit));

但它没有传递负数并给出了这个错误：

'-4000' contains not only digit characters

我现在能做什么？

Answer 1

来自Zend Framework documentation

Note: Validating numbers
When you want to validate numbers or numeric values, 
be aware that this validator only validates digits.
This means that any other sign like a thousand separator
or a comma will not pass this validator.
In this case you should use Zend_Validate_Int or Zend_Validate_Float

Zend Validator用于带有负标记的数字
