Zend表格验证范围日期 [英] Zend Form Validate Range Date
本文介绍了Zend表格验证范围日期的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
示例：
dateGT = 2011-09-05
dateLT = 2011-07-05
如果表单字段设置为：
dateFieldForm = 2011-08-15
我期望验证器返回true！
，如果表单域设置为：
dateFieldForm = 2011-10-15
我期望验证器返回false！
解决方案
对不起，前面的大码：

}
用法：
$ element-> addValidator（new My_Validate_DateCompare（'startdate'））; // exact match
$ element-> addValidator（new My_Validate_DateCompare（'startdate'，null））; // exact match
$ element-> addValidator（new My_Validate_DateCompare（'startdate'，'enddate'））; //之间的日期
$ element-> addValidator（new My_Validate_DateCompare（'startdate'，true））; // not later
$ element-> addValidator（new My_Validate_DateCompare（'startdate'，false））; //不早于
使用全局设置的日期格式（存储在Zend_Registry（Locale））。
还可以自定义每个案例的错误消息。
最新更新：修正错误的默认可选参数它应该是NULL而不是True。
将消息更改为不那么混乱。
某些格式和空格。
who gives me a hand to create a custom validator for Zend Framework, which checks that a date is in to a range?
Example:
dateGT = 2011-09-05
dateLT = 2011-07-05
if the form field is set to: dateFieldForm = 2011-08-15 I expect the validator returns true!
and if the form field is set to: dateFieldForm = 2011-10-15 I expect the validator returns false!

Sorry, large code ahead:

/**
* Error messages

protected $_messageTemplates = array(
self::NOT_SAME => "The date '%value%' does not match the required",
self::NOT_BETWEEN => "The date is not in the valid range",

}
// Not Earlier

// Date is valid
return true;
}
}
Usage:
$element->addValidator(new My_Validate_DateCompare('startdate')); //exact match
$element->addValidator(new My_Validate_DateCompare('startdate', null)); //exact match
$element->addValidator(new My_Validate_DateCompare('startdate', 'enddate')); //between dates
$element->addValidator(new My_Validate_DateCompare('startdate', true)); //not later
$element->addValidator(new My_Validate_DateCompare('startdate', false)); //not earlier
Uses the globally set date format (stored in Zend_Registry('Locale')).
It is also advisable to customize the error messages per case.
Latest update: fixed wrong default optional parameter which should be NULL instead of True. Changed the messages to be less confusing. Some formatting and whitespace.
