Whats the best way to handle the following situation in codeigniter:

家庭控制器具有索引操作和提交操作。

Home controller has an index action and a submit action.

提交操作用于表单提交。我想通过索引控制器加载页面 - 包括在表单提交后，即与形式错误数据重新填充表单输入错误等。

The submit action is used for a form submission. I want to load the page through the index controller though - including after form submission i.e. with form errors data to repopulate form inputs on error etc.

最好的办法

推荐答案

如果您没有索引控制器处理主页加载和表单提交。 redirect（），您将无法使用 set_value（） 用于重新填充表单字段。

If you redirect(), you won't be able to use set_value() for re-populating your form fields.

最简单的方法是使用索引控制器默认加载行为和提交。

What's easiest is having your index controller handle both the default load behavior, and the submission.

function index()
{
    if($this->input->post('foo'))
    { // something was POSTed
        $this->load->library('form_validation');
        //validation rules
    } else
    { // normal view
        //
    }

    $this->load->view('home');
}

或者，您可以设置 / code>和提交控制器，并让他们指向同一个视图，它检测 validation_errors >设置并重新填充表单字段。

Alternatively, you can just set up your index and submit controller, and have them point at the same view, which detects if validation_errors() are set and re-populates form fields accordingly.

第三个选项（hackish）：你可以使用flashdata来保持提交错误，指数。类似这样的工作方式：

Third option (hackish): you could use flashdata to keep submission errors and the submitted form values across a redirect back to index. Something like this would work:

$this->session->set_flashdata('errors', $validation_errors());
