使用 URI 中的 GET 数据进行分页 - Codeigniter

Question

我正在尝试对 DB 返回的结果进行分页。但是当我尝试从 URI 中获取偏移量时：

questions/search?content=foobar/4

/4 应该是偏移量，但它被分配给$_GET 值。

这是控制器中的整个方法：

$results = $this->question->search_results_count($content);
$this->load->library('pagination');
$config['total_rows'] = count($results);
$offset = $this->uri->segment(3);
if ($offset == false) $offset = 0;
$config['full_tag_open'] = '<ul class="pages">';
$config['full_tag_close'] = '</ul>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li><a  class="active">';
$config['cur_tag_close'] = '</a></li>';
$config['prev_tag_open'] = '<li class="prev">';
$config['prev_tag_close'] = '<li>';
$config['next_tag_open'] = '<li class="next">';
$config['next_tag_close'] = '</li>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['first_link'] = '<<';
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['last_link'] = '>>';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['per_page'] = 1;
$config['uri_segment'] = 2;
$config['page_query_string'] = TRUE;
$config['use_page_numbers'] = TRUE;
$config['suffix'] = '?content='.$content;
$config['base_url'] = base_url().'questions/search/';
$this->pagination->initialize($config);

我相信你知道，URI 不是这样工作的。查询字符串必须在末尾（或在# 哈希片段之前）。这个查询字符串：

questions/search?content=foobar/4

表示$_GET['content'] = 'foobar/4';

您需要将分页 URL 更改为以下内容：

questions/search/4/?content=foobar

4后面的/也是可选的。

您必须从分页的$config['base_url'] 中删除查询字符串，而是将其附加到视图中的链接，这很遗憾涉及破解分页类...

或者试试这个未记录的功能：

// After loading the pagination class
$this->pagination->suffix = '{YOUR QUERY STRING}';

或者更好的是，只需在加载类之前将$config['suffix'] = '{YOUR QUERY STRING}'; 添加到您的配置中。这应该会自动将查询字符串添加到每个链接的href。

还需要对您的配置区域进行一些调整：

// Make sure to encode these
// $config['first_link'] = '<<';
$config['first_link'] = '&lt;&lt;';
// $config['last_link'] = '>>';
$config['last_link'] = '&gt;&gt;';

$offset = $this->uri->segment(3);
// Default URI segment is 3, and it's what you use above. Remove this.
// $config['uri_segment'] = 2;

// This should be FALSE (default). Remove it.
// $config['page_query_string'] = TRUE;

// This should be FALSE (default) if you're
// using the URI segment as your OFFSET. Remove it.
// $config['use_page_numbers'] = TRUE;

// Add your query string
$config['suffix'] = '?content='.$content;
$config['base_url'] = base_url().'questions/search/';
$this->pagination->initialize($config);
