分页不正确显示页码编号 [英] Pagination do not correct display page numbers Codeigniter
问题描述
我的控制器函数
函数测试（$ start_from = 0）
{
$ this- > load-> library（'pagination'）;
$ data = array（）;
$ per_page = 3
$ total = $ this-> activity_model-> count_by（）;
$ config ['base_url'] = base_url（）。 '测试';
$ config ['total_rows'] = $ total;
$ config ['per_page'] = $ per_page;
$ config ['uri_segment'] = 2;
$ config ['num_links'] = 2;
$ config ['use_page_numbers'] = TRUE;
$ data ['follow'] = $ this-> activity_model-> get（$ per_page，$ start_from）;
$ this-> pagination-> initialize（$ config）;
$ data ['pagination'] = $ this-> pagination-> create_links（）;
$ this-> load-> view（'front_end / test'，$ data）;
}
我的路线：
$ route ['test'] =user_activity / test;
$ route ['test /（：any）'] =user_activity / test / $ 1;
型号：
code> function get（$ limit，$ start_from）
{
$ sql =SELECT * FROM user_follow LIMIT $ start_from，$ limit;
$ query = $ this-> db-> query（$ sql）;
return $ query-> result_array（）;
}
问题是我有分页1,2,3,4,5。 ...在每一页我显示3项。我想在URL中显示我的页码1,2,3,4,5
当我点击第二页url show 3
当我点击第三页网址显示6等等+3
是可能的，我花了几个小时在互联网上寻求建议，但没有什么我理解[代码] $ config [' use_page_numbers'] = TRUE; [/ code]做我需要的，但在我的情况下，它仍然不工作。
也许你可以建议任何图书馆？
在分页类（/system/libraries/Pagination.php）中进行以下更改， 。
OLD（第146-153行）：
if（$ CI-> uri-> segment（$ this-> uri_segment）！= 0）
{
$ this-> cur_page = $ CI-> ; uri-> segment（$ this-> uri_segment）;
//准备当前页面 - 没有有趣的业务！
$ this-> cur_page =（int）$ this-> cur_page;
}
新：：
为if语句添加else选项，以确保默认值为; page = 1。
if（$ CI-> uri-> segment（$ this-> uri_segment）！= 0）
{
$ this-> cur_page = $ CI-> uri-> segment（$ this-> uri_segment）;
//准备当前页面 - 没有有趣的业务！
$ this-> cur_page =（int）$ this-> cur_page;
}
else
{
$ this-> cur_page = 1;
}
OLD（第175行）： >
$ this-> cur_page = floor（（$ this-> cur_page / $ this-> per_page）+ 1）;
新：：
只要注释掉这一行，因此当前页面服从控制器/ URI。
// $ this-> cur_page = floor （（$ this-> cur_page / $ this-> per_page）+ 1）;
旧（第206行）：
$ i = $ uri_page_number - $ this-> per_page;
新：：
上一页应始终为当前页减去1。
$ i = $ uri_page_number - 1;
OLD（第230行）：
if（$ this-> cur_page == $ loop）
新功能：
缺少分页的URI应视为第1页。
if（$ this-> cur_page == $ loop ||（$ this-> cur_page == 1& $ this-> cur_page = = $ loop））
OLD（第238-247行） / p>
if（$ n ==''&& $ this-> first_url！=''）
{
$ output。= $ this-> num_tag_open。'< a'。$ this-> anchor_class.'href ='。$ this-> first_url。'>'。$ loop 。'< / a>'。$ this-> num_tag_close;
}
else
{
$ n =（$ n ==''）？ ''：$ this-> prefix。$ n。$ this-> suffix;
$ output。= $ this-> num_tag_open。'< a'。$ this-> anchor_class.'href ='。$ this-> base_url。$ n。' >'。$ loop。'< / a>'。$ this-> num_tag_close;
}
新：：
网页网址应使用页码而不是偏移量。
if（$ n ==' &&&&&&&&&&&" first_url！=''）
{
$ output。= $ this-" num_tag_open。'< a'。$ this-> anchor_class.'href ='。$ loop。'>'。$ loop。'< / a>'。$ this-> num_tag_close;
}
else
{
$ n =（$ n ==''）？ ''：$ this-> prefix。$ n。$ this-> suffix;
$ output。= $ this-> num_tag_open。'< a'。$ this-> anchor_class.'href ='。$ this-> base_url。$ loop。' >'。$ loop。'< / a>'。$ this-> num_tag_close;
}
OLD（第256行）： >
$ output。= $ this-> next_tag_open。'< a'。$ this-> anchor_class.'href =' 。$ this-> base_url。$ this-> prefix。（$ this-> cur_page * $ this-> per_page）。$ this-> suffix。'>'。$ this-> next_link 。'< / a>'。$ this-> next_tag_close;
新：：
下一页应始终是当前页和1的总和。
$ output。= $ this-> next_tag_open 。' OLD（第262行）：
$ i =（（$ num_pages * $ this-> per_page） - $ this-> per_page）;
新：：
最后一页应为总页数。
$ i = $ num_pages;
使用新行替换所有旧行。
希望这有助于：）

您需要更新您的控制器功能测试，例如：
function test（$ start_from = 0）
{
$ this-> load-> library（'pagination'）;
$ data = array（）;
$ per_page = 3;
$ total = $ this-> activity_model-> count_by（）;
$ config ['base_url'] = base_url（）。 '测试';
$ config ['total_rows'] = $ total;
$ config ['per_page'] = $ per_page;
$ config ['uri_segment'] = 2;
$ config ['num_links'] = 2;
$ config ['use_page_numbers'] = TRUE;
$ start = $ per_page *（$ start_from-1）;
$ data ['follow'] = $ this-> activity_model-> get（$ per_page，$ start）;
$ this-> pagination-> initialize（$ config）;
$ data ['pagination'] = $ this-> pagination-> create_links（）;
$ this-> load-> view（'front_end / test'，$ data）;
}
这里我添加了一个新的变量$ start，它是 $ per_page *（$ start_from-1）。现在把这个$ start作为模型的参数传递。
这是做每页的项目数乘以（当前页码-1）。这意味着如果你的项目每页为 10 ，您在第二页上的 $ start = 10 *（2-1） 10 。因此，您的结果将从10,20开始，因此一个
希望这有助于：）
My controller function
function test($start_from = 0)
{
$this->load->library('pagination');
$data = array();
$per_page = 3;
$total = $this->activity_model->count_by();
$config['base_url'] = base_url() . 'test';
$config['total_rows'] = $total;
$config['per_page'] = $per_page;
$config['uri_segment'] = 2;
$config['num_links'] = 2;
$config['use_page_numbers'] = TRUE;
$data['follow'] = $this->activity_model->get($per_page, $start_from);
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$this->load->view('front_end/test' ,$data);
}
my route :
$route['test'] = "user_activity/test";
$route['test/(:any)'] = "user_activity/test/$1";
model :
function get($limit,$start_from)
{
$sql = "SELECT * FROM user_follow LIMIT $start_from, $limit";
$query = $this->db->query($sql);
return $query->result_array();
}
Problem is that I have pagination 1,2,3,4,5.... and in every page I display 3 items. I want to do that in url it show my page numbers 1,2,3,4,5
When I click second page url show 3 When I click third page url show 6 and so on +3
is it possible, I spend hours for looking advice on internet but nothing as I understand [code]$config['use_page_numbers'] = TRUE;[/code] do what I need but in my case it still do not work.
Maybe you can advice any library ?
Make the following changes in Pagination class (/system/libraries/Pagination.php) so that it uses page numbers instead of offsets.
OLD (lines 146–153):
if ($CI->uri->segment($this->uri_segment) != 0)
{
$this->cur_page = $CI->uri->segment($this->uri_segment);
// Prep the current page - no funny business!
$this->cur_page = (int) $this->cur_page;
}
NEW:
Add ‘else’ option to if-statement to make sure default is; page = 1.
if ($CI->uri->segment($this->uri_segment) != 0)
{
$this->cur_page = $CI->uri->segment($this->uri_segment);
// Prep the current page - no funny business!
$this->cur_page = (int) $this->cur_page;
}
else
{
$this->cur_page = 1;
}
OLD (line 175):
$this->cur_page = floor(($this->cur_page/$this->per_page) + 1);
NEW:
Simply comment out this line so current page obeys controller/URI.
//$this->cur_page = floor(($this->cur_page/$this->per_page) + 1);
OLD (line 206):
$i = $uri_page_number - $this->per_page;
NEW:
Previous page should always be current page subtracted by 1.
$i = $uri_page_number - 1;
OLD (line 230):
if ($this->cur_page == $loop)
NEW:
URIs missing pagination should be considered page 1.
if ($this->cur_page == $loop || ($this->cur_page == 1 && $this->cur_page == $loop))
OLD (line 238–247):
if ($n == '' && $this->first_url != '')
{
$output .= $this->num_tag_open.'<a '.$this->anchor_class.'href="'.$this->first_url.'">'.$loop.'</a>'.$this->num_tag_close;
}
else
{
$n = ($n == '') ? '' : $this->prefix.$n.$this->suffix;
$output .= $this->num_tag_open.'<a '.$this->anchor_class.'href="'.$this->base_url.$n.'">'.$loop.'</a>'.$this->num_tag_close;
}
NEW:
Page URLs should use page numbers and not offsets.
if ($n == '' && $this->first_url != '')
{
$output .= $this->num_tag_open.'<a '.$this->anchor_class.'href="'.$loop.'">'.$loop.'</a>'.$this->num_tag_close;
}
else
{
$n = ($n == '') ? '' : $this->prefix.$n.$this->suffix;
$output .= $this->num_tag_open.'<a '.$this->anchor_class.'href="'.$this->base_url.$loop.'">'.$loop.'</a>'.$this->num_tag_close;
}
OLD (line 256):
$output .= $this->next_tag_open.'<a '.$this->anchor_class.'href="'.$this->base_url.$this->prefix.($this->cur_page * $this->per_page).$this->suffix.'">'.$this->next_link.'</a>'.$this->next_tag_close;
NEW:
Next page should always be the sum of current page and 1.
$output .= $this->next_tag_open.'<a '.$this->anchor_class.'href="'.$this->base_url.$this->prefix.($this->cur_page + 1).$this->suffix.'">'.$this->next_link.'</a>'.$this->next_tag_close;
OLD (line 262):
$i = (($num_pages * $this->per_page) - $this->per_page);
NEW:
Last page should be the total number of pages.
$i = $num_pages;
Replace all the old lines with new lines. Make sure you do a backup of file before changing.
Hope this helps :)
EDIT:
You need to update your controller function test like :
function test($start_from = 0)
{
$this->load->library('pagination');
$data = array();
$per_page = 3;
$total = $this->activity_model->count_by();
$config['base_url'] = base_url() . 'test';
$config['total_rows'] = $total;
$config['per_page'] = $per_page;
$config['uri_segment'] = 2;
$config['num_links'] = 2;
$config['use_page_numbers'] = TRUE;
$start = $per_page * ($start_from-1);
$data['follow'] = $this->activity_model->get($per_page, $start);
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$this->load->view('front_end/test' ,$data);
}
Here i have added a new variable $start which is $per_page * ($start_from-1). Now pass this $start as argument to model.
What this do is multiply the number of items per page with (current page number -1 ) .This means if your items per page is 10 and you are on the second page the $start = 10 *(2-1) which gives 10. So your result will start from 10,20 and so one
Hope this helps :)
