Codeigniter 表单验证错误：使用表单验证后无法访问页面以填写表单

Question

我在 codeignitor 中创建了一个添加用户表单，其中包含链接 http://example.com/users/add。在控制器中，我有以下用于表单验证的代码：

$this->form_validation->set_rules('firstName', 'First Name', 'required');
$this->form_validation->set_rules('lastName', 'Last Name', '');
$this->form_validation->set_rules('guardian1', 'Guardian First', 'required');
$this->form_validation->set_rules('guardian2', 'Guardian Second', '');
$this->form_validation->set_rules('mobile', 'Mobile Number', 'required');
$this->form_validation->set_rules('phone', 'Phone Number', '');
$this->form_validation->set_rules('dob', 'Date Of Birth', 'required');
$this->form_validation->set_rules('status', 'Account Status', 'required');
$this->form_validation->set_rules('confirmation', 'Confirm Creation', 'required');

if ($this->form_validation->run == FALSE)
{
  redirect('news');
}
else
{
  redirect('users/view');
}

当我尝试访问 url 以添加用户时，它直接将我重定向到 http://example.com/news，而无需打开我可以填写表单的表单页面。 这是我添加用户表单的表单代码：

<form id="form-project" role="form" method="post" action="<?php echo base_url(); ?>users/add" autocomplete="off" novalidate>
    <div class="form-group-attached">
    <div class="row clearfix">

        </div>
      </div>
      <div class="row clearfix">
        <div class="col-md-6">
          <div class="form-group form-group-default input-group required">

            </div>
          </div>
        </div>
      </div>
    </div>
    <br>
    <div class="pull-left">
      <div class="checkbox check-primary">
        <input type="checkbox" checked="unchecked" value="1" id="checkbox-agree" name="confirmation">
        <label for="checkbox-agree">I hereby certify that the information above is true and accurate
        </label>
      </div>
    </div>
    <br>
    <button class="btn btn-primary" type="submit">Submit</button>
    <button class="btn btn-default" type="reset"><i class="pg-close"></i>Clear</button>
  </form>

P.s 我已经加载了表单验证库和 url 助手。

Answer 1

如果条件需要改变你：

if ($this->form_validation->run == FALSE)

到

if ($this->form_validation->run != FALSE)

然后，如果验证失败，用户将被重定向回“users/view”，如果通过则重定向到“news”。

Answer 2

如果你想重定向回你的表单，你的重定向语句应该在 if 块体中

if($this->form_validation->run == FALSE)
{
  redirect('users/view');
}
else
{
  redirect('news');
}
