$ config ['total_rows'] = 1000;
$ this-> pagination-> initialize（$ config）;
我这样做是根据一些建议Ive收到，像你说的，当许多数据工作好，仍然我想爱显示第一个和下一个按钮，所有的时间，我设置total_rows后我的查询（我调用正确的行数），我也试过，结果是一样的，我还需要显示只有4数字和我ustust numb_links ...仍然不工作（我不知道为什么Ci docs说应该工作..）任何想法？
谢谢！
解决方案
生成示例显示的内容实际上很容易。你只需要扩展Pagination的库来适应这一点。我能做到这一点。无论您显示多少页面，它仍显示第一个，最后一个，返回箭头和向前箭头。
如果您想随时显示5页和后面的东西，你需要有很多结果来填充该页面。然后，您在第3页上将 num_links 设置为之前和之后的内容。所以它将是2.我的更改，如果你在第一页上，使其显示4页后适用。见下图。白色是当前页面。绿色是可用的页面。
希望我已经解释一切正确，这适用于你。让我知道。

Ive trying to make a pagination with CodeIgniter, it should be so simple according the manual of Codeigniter, even in the example is like this
« First < 1 2 3 4 5 > Last »
$config['total_rows'] = $this->searchdesc_model->queryallrows();
$config['per_page'] = '10';
$config['uri_segment'] =4;
$config['full_tag_open'] = '<p>';
$config['full_tag_close'] = '</p>';
$config['cur_tag_open'] = '<b>';
$config['cur_tag_close'] = '</b>';
$config['first_link'] = 'First';
$config['last_link'] = 'Last';
$config['last_tag_open'] = '<p>';
$config['last_tag_close'] = '</p>'
$this->load->library('Company_Creation');
in the view I only call it like this pagination->create_links(); ?> (or I send it through the view when I call it from the controller, still I only get this
1 2 3 >
and there is no way to make it look like the exmaple, may sound so dummy but , anyone could help me with this? or have a problem similar?
Thanks
EDIT 1
$config['total_rows'] = $this->searchdesc_model->queryallrows();

$config['last_link'] = ' Last';
$config['last_tag_open'] = '<p>';
$config['last_tag_close'] = '</p>';
$config['next_link'] = '';
$config['next_tag_open'] = '<p id="nextbutton" style="padding-left:5px;">';
$config['next_tag_close'] = '</p>';
$config['prev_link'] = '';
$config['prev_tag_open'] = '<p id="prevbutton" style="padding-right:5px;">';
$config['prev_tag_close'] = '</p>';
$config['num_links']=4;
$data['retorno'] = $this->searchdesc_model->queryalldb($config['per_page'],$this->uri->segment(4,0));
$config['total_rows']=1000;
$this->pagination->initialize($config);
I did this according some advices Ive recieve, like you said when are many data it works good, still I'd LOVE to show first and next button all time, I set total_rows after my query (which I call with the right number of rows) , and I tried before too and the results are the same, I also need to show only 4 numbers and I am ustying numb_links ... still doesnt work (I dont know why Ci docs say should work..) any idea?
Thanks!
解决方案
To produce what the example shows is actually pretty easy. You just need to extend the Pagination's Library to accommodate this. I was able to do this. No matter how many pages you show it still shows first, last, back arrow, and forward arrow.
If you are wanting to show 5 pages at all times with the foward and back stuff you need to have that many results to fill that page. Then you set num_links to what you would want before and after if on the 3rd page. So it would be 2. My changes if you are on the 1st page make it display 4 pages after when applicable. See image below. White is current page. Green is pages available.
Hopefully I've explained everything correctly and this works for you. Let me know.
Controller
$this->pagingConfig = array();
$this->pagingConfig['base_url'] = 'URL';
$this->pagingConfig['total_rows'] = 0;//TOTAL ROWS
$this->pagingConfig['cur_page'] = 0;//CURRENT PAGE NUMBER
$this->pagingConfig['per_page'] = 0;//YOUR RESULTS PER PAGE
$this->pagingConfig['num_links'] = 2;//NUMBER OF LINKS BEFORE AND AFTER CURRENT PAGE IF ON PAGE ONE WILL SHOW 4 PAGES AFTERWARDS IF YOU HAVE ENOUGH RESULTS TO FILL THAT MANY
$this->pagingConfig['first_link'] = "<< First";
$this->pagingConfig['last_link'] = "Last >>";
$this->pagingConfig['full_tag_open'] = "<div class='pagination'>";
$this->pagingConfig['full_tag_close'] = "</div>";
$this->pagingConfig['last_tag_open'] = "";
