如何使用模型验证来确保一个字段> = CakePHP中同一模型中的另一个字段？

I am trying to validate my model, I am using CakePHP 1.2.3.8166 and mysql 5

我正在尝试验证我的模型,我正在使用CakePHP 1.2.3.8166和mysql 5

I have my model definied as it:

我的模型定义如下:

<?php
class Actividad extends AppModel {
    var $name = 'Actividad';
    var $validate = array('maxfield' => array(
        'rule'=> array('chkValue'),
        'message'=>'i2'
    ));

    function chkValue($data){
        return $data["maxfield"]>=$data["minfield"]
    }
}

My table has 2 fields; maxfield & minfield. I need to validate maxfield always >= minfield but I can't figure out how to check minfield value.

我的桌子有2个字段; maxfield&minfield。我需要验证maxfield always> = minfield但我无法弄清楚如何检查minfield值。

2 个解决方案

#1

You can access the value of "minfield" with $this->data['Actividad']['minfield']

您可以使用$ this-> data ['Actividad'] ['minfield']访问“minfield”的值

#2

you already have the validation for maxfield, you just need to do the same thing with the minfield. so your $validate should be like this:

你已经对maxfield进行了验证,你只需要对minfield做同样的事情。所以你的$ validate应该是这样的:

var $validate= array(
               'maxfield' => array(
                  'rule'=> 'chkValue',
                  'message'=>'i2'
                ),
               'minfield' => array(
                  'rule'=> 'chkValue',
                  'message'=>'i2'
               )   
        );

And by the way. 'rule' => 'nameOfValidationFunction'. no need to put in array.

顺便说一下。 'rule'=>'nameOfValidationFunction'。无需放入数组。
