CHtml::activeCheckBox() seems to post '1' when checked, but an empty string ('') when unchecked.  I want a single checkbox for a bunch of attributes (such as `email_publicly_visible`) which have boolean values.  When the checkbox is unchecked, I get a mysql error because it can't store null into the column.

Should CHtml::activeCheckBox() actually post '0' when unchecked?  Is that a bug?

Should an argument be added to it that defines what the value is when unchecked?

Yes, I think adding an option to specify unchecked value is good. Could you create a ticket for that? Thanks!

Another question:  What's the best way to validate checkboxes?

May I suggest to add another type to CTypeValidator that is "boolean"?

[qiang]

Not sure if this is needed. There are several ways to validate a boolean (e.g. CRangeValidator, CNumberValidator). I prefer to using CRangeValidator.

[jonah]

Ok.  Yes, it is definitely not needed, but I think it would be less typing.  And I don't see why the type validator should not support it anyways, it is a ''data type" after all.

I'll use the range validator however..

I want to validate checkBox to know user accept terms and conditions. But the validation is not works.

I did like this:
In model

public function rules()

	{

		return array(

			array('terms', 'required'),  

			array('terms', 'length', 'min'=>1,

				'message'=>'You must accept to continue....'),  

		);

	}

in views:

<?php echo CHtml::activeLabelEx($confirm,'terms'); ?>

<?php echo CHtml::activeCheckBox($confirm,'terms'); ?>

<?php echo CHtml::error($confirm,'terms'); ?>

How to validate this checBox?

Sorry, it should be like this:

public function rules()

{

   return array(

       array('terms', 'required'),  

       array('terms', 'CRangeValidator', 'range'=>array(1),

       'message'=>'You must accept to continue....'),  

   );

}
