Php CodeIgniter 2.0.3分页类起始页
我试图使用codeigniter分页类 这是我的密码Php CodeIgniter 2.0.3分页类起始页,php,codeigniter,pagination,numbers,Php,Codeigniter,Pagination,Numbers,我试图使用codeigniter分页类 这是我的密码 $this->load->library('pagination'); $config['base_url'] = base_url('language/'.$this->uri->segment(2)); $config['total_rows'] = $page_count; $config['per_page'] = 1; $config['num_links'] = '2'; $config['uri_se
$this->load->library('pagination');
$config['base_url'] = base_url('language/'.$this->uri->segment(2));
$config['total_rows'] = $page_count;
$config['per_page'] = 1;
$config['num_links'] = '2';
$config['uri_segment'] = '2';
$this->pagination->initialize($config);
$data['pages'] = $this->pagination->create_links();
但是,在第一个页面中,url如下所示
localhost/language/something/
而第二页是
localhost/language/something/1
这看起来有点奇怪,是否可以让url在第一页以1开头?url中的数字不是页码,而是记录偏移量 例如,如果将其设置为每页25条记录:
$config['per_page'] = 25;
第1页的URL如下所示:
localhost/language/something/
localhost/language/something/25
第2页是这样的:
localhost/language/something/
localhost/language/something/25
第三页
localhost/language/something/50
下面是重写内置分页类的代码。将它放在应用程序/库中,然后像平常一样做其他事情 我在从原始类编辑的每一行中添加了一条注释 注意:在示例代码中,您将页面总数放在total_rows配置值中。请确保输入记录的总数,而不是总页数

感谢您的输入,但是是否可以更改此设置而不是显示偏移量,而是显示当前页面?您需要扩展(继承)分页库。如果你告诉我你使用的是哪个版本的CI,我会发布代码。我使用的是最新版本,应该是2.0。3@Jonathan如果你想在URI中显示页码而不是索引,你可以设置配置:$config['use_page_numbers']=true;这是CodeIgniter 2.1中添加的新功能:)
