是否可以强制表单助手根据需要呈现字段，即使它不在CakePHP中？ [英] Is it possible to force the form helper to render a field as required even if it isn't in CakePHP?

问题描述

是否有一些参数或解决方法我可以使用表单助手渲染一个字段，如果它是模型需要的，即使模型实际上不需要它吗？

Is there some parameter or workaround I can use to have the form helper render a field as if it were required by the model even if the model does not actually require it?

（我正在寻找cakephp所需的渲染类型，而不是实际的'required'表单属性，使这是一个不同的问题比 Cakephp Form Helper ）

(I'm looking for the cakephp required rendering type, not the actual 'required' form property making this a different question than Cakephp Form Helper)

推荐答案

所有必需样式是一个特定的CSS类设置自己：

All the "required" style is is a specific CSS class you can set yourself:

$this->Form->input('foo', array('div' => array('class' => 'input text required')));
