Question

I have to create my custom FORM:isvalid() function in my form like below, because I have to check if one of these 2 fields are at least filled out:

class Products_AddForm extends Zend_Form {

public function isValid($data)
{

    // Check special post data
    $pzn_val = $data['PZN'];
    $mar_val = $data['PZO'];

    if(empty($pzn_val) && empty($mar_val)) {
        $this->getSubForm('sub1')->getElement('PZN')->setErrors(array('PZN or PZO needed'));
        $this->getSubForm('sub2')->getElement('PZO')->setErrors(array('PZN or PZO needed'));
    }

    // Standard validation
    return parent::isValid($data);

}

The errors for PZN and PZO will only fire if another error (other field) will be found.
How can I get the form error?
Field PZN and PZO are defined as not required.

TIA
Matt

Try:

public function isValid($data) {
    $isValid = parent::isValid($data); 
    // Check special post data
    $pzn_val = $data['PZN'];
    $mar_val = $data['PZO'];

    if(empty($pzn_val) && empty($mar_val)) {
        $this->getSubForm('sub1')->getElement('PZN')->setErrors(array('PZN or PZO needed'));
        $this->getSubForm('sub2')->getElement('PZO')->setErrors(array('PZN or PZO needed'));
        $isValid = false;
    }    

    return $isValid;
}
