您应该检查$pizza->getInputFilter（）是否返回一个实现Zend\InputFilter\InputFilterInterface接口的对象。因为表单类的setInputFilter（）方法只接受此类对象 请删除getInputFilter
方法中的else
。我认为这就是造成错误的原因。这就是为什么会出现错误：null如果给定
，$inputfilter
将不会第一次返回
我帮你改正了。用以下方法替换您的方法：
public function getInputFilter(){
if (!$this->inputFilter) {
$inputfilter = new InputFilter();
$inputfilter->add(array(
'name' => 'name',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
array('name' => 'StripTags')
),
'validators'=> array(
array('name' => 'StringLength',
'options'=> array(
'encoding' => 'UTF-8',
'min' => 5,
'max' =>30,
))
)
));
$inputfilter->add(array(
'name'=> 'ingredients',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
array('name' => 'StripTags')
),
'validators'=> array(
array('name' => 'StringLength',
'options'=> array(
'encoding' => 'UTF-8',
'min' => 5,
'max' =>255,
))
)
));
$inputfilter->add(array(
'name' => 'smallprice',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
array('name' => 'StripTags')
),
'validators'=> array(
array('name' => 'StringLength',
'options'=> array(
'encoding' => 'UTF-8',
'min' => 1,
'max' => 5,

)
));
$inputfilter->add(array(
'name' => 'bigprice',
'required' => true,
'filters' => array(
array('name' => 'StringTrim'),
array('name' => 'StripTags')
),
'validators'=> array(
array('name' => 'StringLength',
'options'=> array(

$inputfilter->add(array(

希望有帮助 实际上，名为Pizza
的模型存在问题，因为输入过滤器是在ModelPizza
上定义的。所以请先检查你的模型，或者写下模型，这样我们可以解决你的问题。谢谢并确保您已经在您的模型上添加了这个namespace Pizza\Model；使用Zend\InputFilter\InputFilter；使用Zend\InputFilter\InputFilterAwareInterface；使用Zend\InputFilter\InputFilterInterface；类Pizza实现了InputFilterAwareInterface{…
我添加了模型的代码你能检查它吗pllz:染色它返回：$inputfilter=new inputfilter（）；…..$this->inputfilter=$inputfilter；返回$this->inputfilter；当我尝试它时，错误消失了，但数据没有存储在DB中？测试条件是否if（$add_form->isValid（））
返回true
。尝试在if语句中回显'success'；
。非常感谢您，它终于起作用了：D问题出在这一系列代码中：return$this->redirect（）->toRoute（'pizza'）；在：函数addAction（）中
