我无法访问我的数组。
我有一个类似的URL：
http://localhost:8000/admin/country_index2/
Country2方法如下：
public function country_index2($sort_by = 'country_id', $sort_order='ASC', $offset = 0){
$this->load->model('model_admin');
$this->load->library('pagination');
/* This Application Must Be Used With BootStrap 3 * */
$config['full_tag_open'] = "<ul class='pagination'>";
$config['full_tag_close'] ="</ul>";
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = "<li class='disabled'><li class='active'><a href='#'>";
$config['cur_tag_close'] = "<span class='sr-only'></span></a></li>";
$config['next_tag_open'] = "<li>";
$config['next_tagl_close'] = "</li>";
$config['prev_tag_open'] = "<li>";
$config['prev_tagl_close'] = "</li>";
$config['first_tag_open'] = "<li>";
$config['first_tagl_close'] = "</li>";
$config['last_tag_open'] = "<li>";
$config['last_tagl_close'] = "</li>";
$config['base_url'] = 'http://localhost:8000/admin/country_index';
$config['total_rows'] = $this->db->get('mhcountry')->num_rows();
$config['per_page'] = 10;
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
// table, limit, offset
// $data['query'] = $this->db->get('mhcountry', $config['per_page'], $this->uri->segment(3));
$data['query'] = $this->model_admin->search_countries($config['per_page'] , $offset, $sort_by, $sort_order);
$data['templateVersion'] = 'template1';
$data['headerVersion'] = 'header1';
$data['navBarVersion'] = 'navbar1';
$data['main_content'] = 'detail-wrap/admin/country_index';
$data['page_title' ] = 'example.com - App';
$data['footerVersion'] = 'footer1';
// $data['num_rows'] = $this->db->get('mhcountry')->num_rows();
//if(empty($page_number)) $page_number = 1;
//$offset = ($page_number-1) * $config['per_page'];
//var_dump($data);
$this->load->view('detail-wrap/includes/template1', $data);
}
search_countries函数的内容如下：
function search_countries($limit, $offset, $sort_by, $sort_order){
// you can also do this with if then else
$sort_order = ($sort_order == 'DESC') ? 'DESC' : 'ASC';
$sort_columns = array('country_id', 'country');
$sort_by = (in_array($sort_by, $sort_columns)) ? $sort_by : 'country';
// results query
$query = $this->db->select('country', 'country_id')
->from('mhcountry')
->limit($limit, $offset)
->order_by($sort_by, $sort_order);
$results['rows'] = $query->get()->result();
$query_count = $this->db->select('COUNT(*) as count', FALSE)->from('mhcountry');
// $tmp = $query_count->get()->result();
//$results->[num_rows] =$tmp[0]->count;
return $results;
#print_r($results);
#die;
}
在我看来，我有这个：
<div class="bs-example">
Found
<?php
echo $num_rows ;
?>
Countries
<table class="table table-hover">
<thead>
<tr>
<th>Country ID</th>
<th>Country Name</th>
<th>Status</th>
<th>Options</th>
</tr>
</thead>
<tbody>
<?php
//print_r(data[$query]);
//foreach ($query->result() as $row ) {
foreach ($query->result_array() as $row ) {
?>
<tr>
<td><?php echo $row['country_id']; ?></td>
<td><?php echo $row['country']; ?></td>
<td>Carter</td>
<td>johncarter@mail.com</td>
</tr>
<?php } ?>
</tbody>
</table>
<?php echo $pagination; ?>
</div>
[狙击]
当我转储print_r（$results）时，我得到以下内容：
Array ( [rows] => Array ( [0] => stdClass Object ( [country] => Canada ) [1] => stdClass Object ( [country] => Japan ) [2] => stdClass Object ( [country] => Korea ) [3] => stdClass Object ( [country] => 0 ) [4] => stdClass Object ( [country] => pakist ) [5] => stdClass Object ( [country] => ddsdsd ) [6] => stdClass Object ( [country] => texas ) [7] => stdClass Object ( [country] => scotland ) [8] => stdClass Object ( [country] => scotland ) [9] => stdClass Object ( [country] => scotland ) ) )
但我似乎无法访问它们以在视图中显示它们。该视图没有显示国家。
[编辑]我认为发生的情况是，我正在传递一个多维数组，并且访问数据时遇到了困难。我在这里发现了一个类似的线程使用Codeigniter 访问多维数组
****新更新***
请注意，方法"function country_index2（…）"按原样工作，并将结果返回给控制器。控制器还清楚地将结果发送到视图。我遇到的问题是无法在视图中显示结果。只是想澄清一下。
是的，有几行是关于排序和分页的，但这还没有实现，就像坐在那里无所事事一样好。很高兴听到。
print_r($results)是一个包含对象的数组。
你可以这样循环：
foreach ($results['rows'] as $row) {
然后访问CCD_ 2的属性，如下所示：
$row->country
因为在控制器中，您已经在$data数组中设置了结果，并将视图部分传递给了您。
$data['query'] = $this->model_admin->search_countries($config['per_page'] , $offset, $sort_by, $sort_order);
如果您检查了模块，那么$query->get()->result();将为您提供数据对象而不是数组。
应为：
<?php
if( is_array($query) && count( $query ) > 0 ) :
foreach ($query['rows'] as $row ) { ?>
<tr>
<td><?php echo $row->country_id; ?></td>
<td><?php echo $row->country; ?></td>
<td>Carter</td>
<td>johncarter@mail.com</td>
</tr>
<?php }
endif; ?>
您可以保持代码的原样。只需修复这个函数
function search_countries($limit, $offset, $sort_by, $sort_order){
//your other codes here
//$query.....
//$results['rows'] = $query->get()->result();//replace it as bellow
$results = $query->get();
return $results;
}
注意
这行在您的search_countries函数中没有影响
$query_count = $this->db->select('COUNT(*) as count', FALSE)->from('mhcountry');
希望它能解决你目前的问题。

请记住，您的分页不会像您当前的设计一样工作
有两个错误。第一个错误出现在方法search_countries（）中；活动记录语法不正确。
之前：
$query = $this->db->select('country', 'country_id')
->from('mhcountry')
->limit($limit, $offset)
->order_by($sort_by, $sort_order);
之后：
$query = $this->db->select('country_id country')
->from('mhcountry')
->limit($limit, $offset)
->order_by($sort_by, $sort_order);
第二个错误出现在VIEW中。当我接收的是一个对象而不是一个数组时，视图循环应该是这样的：
<tbody>
<?php
//var_dump($query);
foreach ($query as $row ) {
?>
<tr>
<td><?php echo $row->country_id; ?></td>
<td><?php echo $row->country; ?></td>
<td>something</td>
<td>someone</td>
</tr>
<?php } ?>
</tbody>
感谢您的帮助。它现在正在工作。
