伊夫试图与笨分页,应该根据笨的手动那么简单,即使是在例如是这样如何配置分页codeigniter?

«第一< 1 2 3 4 5>最后»

$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'); 

在视图中我只把它叫做这样的分页 - > create_links(); ?>(或者我通过时,我把它从控制器的观点发送,还是我只得到这个

1 2 3>

,有没有办法让它看起来像〔实施例,听起来所以假,但任何人都可以帮我吗?还是有相似?

感谢

$config['total_rows'] = $this->searchdesc_model->queryallrows(); 
$config['per_page'] = '5'; 
$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>'; 
$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); 

一个问题,我这样做是根据一些建议伊夫收到,就像你说的那样,当许多数据工作的很好时,我仍然喜欢随时显示第一个和下一个按钮,在我的查询(我用正确的行数调用)之后设置了total_rows,并且之前我也尝试过结果是一样的,我也只需要显示4个数字,我很讨厌numb_links ...仍然不起作用(我不知道为什么Ci文件应该工作..)任何想法?

谢谢!

据我所知,这只是看上去什么像分页的例子。不是使用CodeIgniter分页类可以创建的实际分页。您可能需要扩展分页类并自己调整'create_links()'方法。 – 2012-02-13 05:12:40

谢谢,有关如何由我自己创建它们的任何想法? (我讨厌codeigniter给出了这些例子,他们甚至不提供如何使它的线索......) – jpganz18 2012-02-13 05:18:02

你正在使用哪个CodeIgniter版本? – 2012-02-13 05:29:19

生成示例所示的内容其实很简单。你只需要扩展分页的库来适应这一点。我能够做到这一点。无论显示多少页面,它仍然显示首先,最后,后退箭头和前进箭头。

如果你想要随时显示5页的正面和背面的东西,你需要有这么多的结果来填充该页面。然后在第3页上设置num_links之前和之后的值。所以它会是2.如果您在第一页上,我的更改会在适用后显示4页。见下图。白色是当前页面。绿色是可用的页面。

我写了关于Cdeigniter分页的教程。请看看并提出建议https://www.cloudways.com/blog/pagination-in-codeigniter/ – 2017-11-24 14:02:07

您得到1 2 3 >而不是« First < 1 2 3 4 5 > Last »的唯一原因是您的结果中没有足够的行来生成超过3页。

  • 如果您不需要它们,默认情况下不会显示“第一个”和“最后一个”链接。从documentation的例子中我们不太清楚。

  • 直到您超过第1页,该示例实际上位于第3页(“3”是粗体)之前,您将不会获得“Previous”链接。

  • 由于您在配置中提供了自己的模板而不是使用默认值,因此实际结果会稍有不同。

如果你想要做一个快速的测试,看看更多的联系,只是减少你per_page到一个较低的数字或包括在total_rows更多的行。显示的链接总数也可配置为num_links

+0

谢谢!我减少了链接到5(现在我只有18行数据),但如果我设置total_rows一个高参数我得到,就像你说的,第一和最后的链接,问题,如果我点击最后我去该页面(页码1000),它没有数据,任何其他方式来模拟? – jpganz18 2012-02-13 05:39:15

你只需要更多的数据。将'total_rows'设置为任意数字仅用于快速测试以查看链接,这不是您实际想要执行的操作。 – 2012-02-13 05:51:34

谢谢,我已经在1000上设置了total_rows,但是当我点击“最后”链接发送给页面1000 ...没有数据......任何想法如何解决它? – jpganz18 2012-02-13 06:12:09
