Silverstripe条件验证

Question

我有一个表单有多个动作,例如创建订单和创建报价.

根据点击的操作,我需要应用不同的验证.例如,报价不需要订单参考.

在Silverstripe中这可能吗？如果没有,我将如何得到它？

public function Order($request=null) {
 $form = Form::create(
    $this,
    __FUNCTION__,
    FieldList::create(
        TextField::create('Name', 'Your Full Name'),
    TextField::create('OrderRef', 'Purchase Order #')
    ),
    FieldList::create(
        LiteralField::create('Cancel', '<a class="cancel button alert">Don\'t save</a>'),
        FormAction::create('saveQuote', 'Save Quote'),
        FormAction::create('saveOrder', 'Save Order')->addExtraClass('success')
    ),
    RequiredFields::create('Name', 'OrderRef')
);

return $form;
}

Answer 1

为此,您可能需要创建自定义RequiredFields子类以有条件地设置所需的字段:

class CustomValidator extends RequiredFields {
    public function php($data) {
        if($this->form->buttonClicked()->actionName() == 'saveQuote') {
            $this->addRequiredField('FieldName'); // ...
        } else {
            $this->addRequiredField('OtherFieldName'); // ...
        }

        return parent::php($data);
    }
}

然后在表单中使用它,如:

$form = new Form(
    $this, 'FormName', $fields, $actions, new CustomValidator()
);
