Zend Framework 2 表单错误未显示
Zend Framework 2 Form Errors Not Showing
我想弄清楚为什么 Zend Form 没有向我的表单返回错误。
当我查看：Zdendframework/library/form/form.php 文件时，我可以看到正在生成错误：
public function isValid()
{
if ($this->hasValidated) {
return $this->isValid;
}
...
if (!$result) {
$this->setMessages($filter->getMessages());
}
return $result;
}
如果我 var_dump($filter->getMessages()，我看到了错误。
然而，当我返回我的表单并尝试转储消息时，有 none 可用。
我的控制器
$prg = $this->prg();
if ($prg instanceof Response) {
return $prg;
} elseif ($prg === false) {
return $this->getVM()->setVariables([
'form' => $this->registerForm
]);
}
$this->registerForm->setData($prg);
if ( ! $this->registerForm->isValid($prg) ) {
return new ViewModel(['form' => $this->updateForm]);
}
我的表格：

InputFilterInterface $inputFilter,

在控制器中，如果我转储这个：
$result = $this->registerForm->getInputFilter()->getMessages();
die(var_dump($result));
这输出：
array (size=1)
'user' =>
array (size=1)
'firstName' =>
array (size=1)
'isEmpty' => string 'Value is required and can't be empty' (length=36)
从评论和 HappyCoder 本身推断，问题出在控制器中，错误的表单返回到视图。
if ( ! $this->registerForm->isValid($prg) ) {
return new ViewModel(['form' => $this->updateForm]);
}
应该是：

应该是：
