cakephp隐藏字段问题

Question

我在名为 add.ctp 的 View 中的输入字段有问题。当输入类型设置为'text'时，程序序列正常。但是当我将输入类型更改为“隐藏”时，会显示以下错误:

The request has ben black-holed. Error: The requested address was not found on this server.

mod-rewrite 似乎已激活。任何想法，这可能是什么原因？

您的代码没有错误。 CakePHP's Security component检查隐藏的表单字段以防止最终用户篡改:

By default SecurityComponent prevents users from tampering with forms. It does this by working with FormHelper and tracking which files are in a form. It also keeps track of the values of hidden input elements. All of this data is combined and turned into a hash. When a form is submitted, SecurityComponent will use the POST data to build the same structure and compare the hash.

使用 FormHelper::unlockField 使字段免于此功能:

$this->Form->unlockField('User.id');
