Codeigniter表单验证 - 如何成功后取消设置表单值？ [英] Codeigniter Form Validation - how to unset form values after success?

问题描述

我意识到这个请求违反了CI文档中提供的示例（建议单独的成功页面视图），但是我想在表单成功提交后重新利用给定的表单视图 - 显示成功消息然后显示空白表单。我尝试了几种方法未成功清除验证集值（取消设置 $ _ POST ，将规则/字段设置为空数组并重新运行验证）。

I realise this request goes against the example provided in the CI documentation (which advises a separate 'success' page view), but I would like to reutilise a given form view after a form has been successfully submitted - displaying a success message then displaying a blank form. I've tried a few ways unsuccessfully to clear the validation set values (unsetting $_POST, setting rules / fields to an empty array and rerunning validation).

我可以重定向到同一个页面，但是我必须设置一个会话变量来显示一个成功消息 - 这是一个凌乱的方法。

I could redirect to the same page, but then I'd have to set a session variable to display a success message - which is a messy approach.

任何想法如何最好地实现上述目标？

Any ideas how to best achieve the above?

推荐答案

这样，没有提交...。这也提供了一种显示flash_data的方法。

Redirect to itself. This way, no submissions have been run... This also gives you a way to show the flash_data.

    $this->load->library('form_validation');

    $this->form_validation->set_rules('firstname', 'First Name', 'required');
    $this->form_validation->set_rules('surname', 'Sur Name', 'required');

    if ($this->form_validation->run() === TRUE)
    {
                    // save data

        $this->session->set_flashdata('message', 'New Contact has been added');
        redirect(current_url());
    }

    $this->load->view('contacts/add', $this->data);
