Validation on alphabetic character

[quantro]

i read this line in the zend framework programmer references guide :
Alpha
Returns true if and only if $value contains only alphabetic characters. This validator includes an option to also consider white space characters as valid.

I try to use that, but if i use white space as input, it reject and shows error. then i realize that the references contain this line :
This validator includes an option to also consider white space characters as valid.
the question is, how to use the option??
can someone show me the way??

Hi Quantro,

Just pass "true" to the constructor of Alpha filter e.g.:

Code: Select all

$filterChain->addFilter(new Zend_Filter_Alpha(true));

Code: Select all

$this->addElement('text', 'element1', array(
            'label'      => 'element1:',
            'required'   => true,
            'validators' => array(
                array('validator' => 'StringLength', 'options' => array(0, 20))
                )
        ));

that's my code, ho to add that filter?? or can i add it as validator??

Code: Select all

'validators' => array(
                array('validator' => 'StringLength', 'options' => array(0, 20)),
                array('validator' => 'Alpha', 'options' => true)
                )
