php - 在 codeigniter 中的文本框旁边显示验证错误消息

Question

我是 codeigniter 的新手。我想在文本框旁边显示错误消息。我的 View 文件 create.php 包含以下代码。

  <?php     
    echo validation_errors();               //validation
    echo form_open('news/create');  //create a form   
  ?>
 <div class="boxes">
   <div class="common">
     <div class="lables">
        <label for="name">Name</label>
     </div>

     <div class="text_boxes">
        <input type="text" name="uname" /><div id="infoMessage"><?php echo $message;?></br>
    </div>
</div>`

下面是我的 Controller 模型:

 public function create()
{
    $this->load->helper('form');
    $this->load->library('form_validation');

    $data['title'] = 'Insert Items';

    $this->form_validation->set_rules('uname','required|min_length[6]|max_length[15]');
    $this->data['message'] = enter your name;
    $this->form_validation->set_rules('uaddress','enter your address','required');
    $this->form_validation->set_rules('email','Enter emailid','required');
    $this->form_validation->set_rules('mobile','Enter mobile number','required');

     if ($this->form_validation->run() === FALSE)
    {
        $this->load->view('templates/header', $data);
        $this->load->view('news/create');
        $this->load->view('templates/footer');

    }
    else
    {
        $this->news_model->set_news();
        $this->load->view('news/success');
    }
    /** View Details **/
    $data['user_data'] = $this->news_model->get_details();
    $data['title'] = 'Database Details';

    $this->load->view('templates/header');   //used to call the view file(header) which is in templates/header
    $this->load->view('news/index', $data);         //used to call the view file(index) ie:news/index
    $this->load->view('templates/footer');              //used to call the view file(footer) ie:templates/header
    /**     END **/
}

但我知道 #infoMessage 将始终显示在 用户名字段 之后。但我真的不知道如何在自定义位置显示错误消息。

请帮我解决这个问题!!

编辑:添加后

 <input type="text" name="uname"  value="<?php echo set_value('uname'); ?>" />
  <div id="infoMessage"><?php echo form_error('uname'); ?></div></br> 

此代码如下图所示:

如果您阅读 CI documentation你可以找到答案。

用这个替换你的行

<input type="text" name="uname"  value="<?php echo set_value('uname'); ?>" /><div id="infoMessage"><?php echo form_error('uname'); ?></div></br>
