Question

我必须建立我的习惯<条码>:isvalid(>,载于我的<条码>。如下文所示,因为我必须检查这2个领域中是否至少填满了:

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;
}
