Question

这是我第一次在StackOverflow中询问。所以请原谅我，如果我错了，我是PHP和CodeIgniter的新手。好的，我有一个用于创建新数据的页面。我正在CI上使用表单验证，但是如果我填写表单没有任何事情，那就不行了。这是我的代码。

我的控制器

    parent::__construct();

        redirect('bunker/login', 'refresh');

    $user = $this->ion_auth->user()->row();
    if(empty($user->last_pwd_change)){
        redirect('bunker/account/renew', 'refresh');

抱歉，如果我的英语太糟糕了。

Answer 1

重构控制器#create（）方法，以便不使用操作后检查。而是使用表单验证运行方法。

示例：

$this->form_validation->set_rules('page_id', "Page Name", 'required|numeric|xss_clean');
$this->form_validation->set_rules('article_title', "Article Title", 'required|xss_clean');

$this->form_validation->set_rules('article_url', "Custom URL", 'xss_clean');
$this->form_validation->set_rules('article_status', "Publication Status", 'required|xss_clean');
$this->form_validation->set_rules('article_excerpt', "Excerpt", 'required|min_length[250]|xss_clean');
$this->form_validation->set_rules('article_content', "Content", 'required|min_lenght[500]|xss_clean');

$this->form_validation->set_error_delimiters('<li>','</li>');
if ($this->form_validation->run() == TRUE){
    // Display Succeeded Site or something else
} else {
    // Display Failed Site or Errors or something else
}

表单验证不适用于代码点火器
