how to implement input filter and validation

I am a newbie in zendframework. I am using zendframework version 2.

I have a ClientForm class which is inheriting from Zend\Form\Form.

class Client extends Form
{
    public function __construct($name = null, $options = array())
    {
        if (null == $name) $name = 'ClientFrom';
        parent::__construct($name, $options);

        $this->add(array(
            'name' => 'clientName',
            'type' => 'Text'
        ));

        $this->add(array(
            'name' => 'address1',
            'type' => 'Text'
        ));
    }
}

I need to implement validation and filtering for the above form.

Rules for Validation

'clientName' => required, min = 3, max = 25

Rules for Filter

'clientName' => [a-zA-Z0-9_ ]

Questions

  1. Can I implement this rules and filter in the same class as Form (without creating a new input filter class)
  2. Please show me example on how to implement above rules on my above class.

Thank you.

Try this:

    $this->add(array(
        'name' => 'clientName',
        'type' => 'text',
        'required' => true,             
        'validators' => array(
             new Validator\RegexValidator('/^#[a-zA-Z0-9_ ]$/'),
             new Validator\StringLength(array('min'=>3 ,'max' => 25))
         )             
    ));

There is the Zend\InputFilter-Component that you'd use for this kind of task. There's a lot of examples out there, some programatical ones like here or some configurational ones like here or here.

The later two being examples used for specific Doctrine-Validators, but you can use them for any normal Zend\InputFilter, too.

I suppose you have no code yourself yet ... well.

'clientName' => required, min = 3, max = 25

This one isnt too difficult, heres some easy code ... ill write it extremely simple and readable, you can shorten the if-statements if you want:

if(!empty($clientName)) {
    if(!($clientName > 25)) {
        if(!($clientName < 3)) {
            echo "valid name!";
        }
    }
} else {
    return false;
}

'clientName' => [a-zA-Z0-9_ ]

Either you use RegEx or string-functions where you only allow these specific characters.
