国家下拉菜单中没有填充数据代码点火器

Question

国家/地区下拉列表中没有填充数据代码点火器，任何机构都可以帮助我，我想要查看国家/地区列表，以便我可以选择国家/地区。当我在视图中添加选择代码以进行下拉时，它会隐藏列表并保存按钮。

我的模特

public function get_Country() {
        $this->db->select('code, name')->from("country");
        $query = $this->db->get();
        return $query->result_array();
    }

我的控制器

public function get_Country() {
        $ctry = $this->job_post_model->get_Country();
       // debug($ctry);
    }

我的查看代码

<div class="row">
    <div class="span8">

Answer 1

在模型中：

替换

return $query->result_array();

有

返回 $query->result();

在视图中：

替换

 <?php $countries = get_Country(); ?>
 <select name="country">
       <option>Select your country*</option>
           <?php foreach ($countries as $country) { ?>
            <option value="<?php echo $country->name ?>" </option>
      <?php }
       ?>
  </select>

有

 <?php $countries = get_Country(); ?>
 <?php echo form_dropdown('country',$countries, 0,'required'); ?>

在 Codeigniter 中使用下拉菜单中的 Codeigniter

Answer 2

您的模型是正确的，但您确实需要决定是以array 还是object 访问数据。这将决定您如何访问视图中的数据。

$query->result_array() 返回一个array

$query->result() 返回一个object

在您的控制器中，您需要使用您的模型。

// Load your model into your controller
$this->load->model('your_model');

// use your_model method to set $data['countries']
$data['countries'] = $this->your_model->get_Country();

// You will access $countries in your view by passing it to your view
$this->load->view('your_view'), $data);

在您看来，如果您在模型中选择$query->result()：

<select name="country">
  <option>Select your country*</option>
<?php foreach ($countries as $country): ?>             
  <option value="<?php echo $country->name ?>"><?php echo $country->name ?></option>
<?php endforeach; ?>
</select>

Answer 3

你的控制器没有return任何东西，所以需要修改控制器如下。

控制器：

public function get_Country() {
   return $ctry = $this->job_post_model->get_Country();
}

还有您的 VIEW 以数组形式返回结果，您需要使用 $country['name'] 代替 $country->name。

查看：

 <?php $countries = get_Country(); ?>
       <select name="country">
             <option>Select your country*</option>
             <?php foreach ($countries as $country) { ?>
             <option value="<?php echo $country['code'] ?>"><?php echo $country['name'] ?></option>
              <?php }
              ?>
        </select>
