在uri - Codeigniter中获取GET数据 [英] Pagnation with GET data in the uri - Codeigniter

问题描述

我试图分页DB返回的结果。但是当我尝试从URI获取偏移量时：

questions / search？content = foobar / 4 p>

/ 4 应为偏移量，但分配给 $ _ GET value。

这是控制器中的整个方法：

http://pastebin.com/QFJddMDJ

  $ 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）; 
  

解决方案

t工作这样。查询字符串必须在结尾（或在＃散列片段之前）。此查询字符串：

  questions / search？content = foobar / 4 
  pre> 
 
 
表示 $ _ GET ['content'] ='foobar / 4';  
 
 
 
您需要将分页网址更改为以下内容：
 问题/搜索/ 4 /？content = foobar 
  
  /  
 
 
 
您必须从分页的 $ config ['base_url']中删除查询字符串 
 
 
或者尝试这个未公开的功能：
  //加载分页类后
 $ this-> pagination-> suffix ='{YOUR QUERY STRING}'; 
  
或者更好的方法是添加 $ config ['suffix'] = {YOUR QUERY STRING}'; 加载您的配置。这应该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： / p> 
 
 
  //确保对这些
 // $ config ['first_link'] ='< ; 
 $ config ['first_link'] ='& lt;& lt;'; 
 // $ config ['last_link'] ='>>'; 
 $ config ['last_link'] ='& gt;& gt;'; 
 
 $ offset = $ this-> uri-> segment（3）; 
 //默认的URI段是3，它是你在上面使用的。删除此。 
 // $ config ['uri_segment'] = 2; 
 
 //这应该是FALSE（默认）。去掉它。 
 // $ config ['page_query_string'] = TRUE; 
 
 //如果你是
 //使用URI段作为你的OFFSET，这应该是FALSE（默认）。去掉它。 
 // $ config ['use_page_numbers'] = TRUE; 
 
 //添加您的查询字符串
 $ config ['suffix'] ='？content ='。 
 $ config ['base_url'] = base_url（）。'questions / search /'; 
 $ this-> pagination-> initialize（$ config）; 
  
 
Im trying to paginate results returned by DB. But when I try to get the offset from URI:

questions/search?content=foobar/4

/4 should be the offset but it is assigned to the $_GET value.

This is the whole method in the controller: 

http://pastebin.com/QFJddMDJ
$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);

解决方案
As I'm sure you know, URIs don't work like that. The query string must be at the end (or before a # hash fragment). This query string:
questions/search?content=foobar/4
Means $_GET['content'] = 'foobar/4';

You need to change your pagination URLs to something like this:
questions/search/4/?content=foobar
The / after the 4 there is also optional.

You'll have to remove the query string from your pagination's $config['base_url'] and instead append it to the links in the view, which sadly involves hacking the pagination class...

Or try this undocumented feature:
// After loading the pagination class
$this->pagination->suffix = '{YOUR QUERY STRING}';
Or better yet, just add $config['suffix'] = '{YOUR QUERY STRING}'; to your config before loading the class. This should automatically add the query string to every link's href.

Some adjustments to your config area also needed:
// 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);
