我尝试使用CodeIgniter进行分页,根据Codeigniter的手册,它应该很简单,即使在示例中是这样的
« 第一个 最后一个 »
$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');
在视图中我只这样称呼它 pagination->create_links(); ?> (或者当我从控制器调用它时,我通过视图发送它,但我仍然只得到这个
1 2 3 >
没有办法让它看起来像这个例子,可能听起来很愚蠢,但是,任何人都可以帮助我吗?或者有类似的问题?
Thanks
EDIT 1
$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);
我根据我收到的一些建议这样做了,就像你说的,当有很多数据时它效果很好,我仍然喜欢一直显示第一个和下一个按钮,我在查询后设置了total_rows(我用正确的行数调用它) ),我之前也尝试过,结果是一样的,我也只需要显示 4 个数字,我正在使用 numb_links ...仍然不起作用(我不知道为什么 Ci 文档说应该起作用..)有什么想法吗?
Thanks!
生成示例所示的内容实际上非常简单。您只需要扩展分页库来适应这一点。我能够做到这一点。无论您显示多少页,它仍然显示第一个、最后一个、后退箭头和前进箭头。
如果您希望始终显示 5 个页面,其中包含前进和后退的内容,则需要有那么多结果来填充该页面。然后你设置num_links
到第三页之前和之后您想要的内容。所以它将是 2。如果您在第一页,我的更改将使其在适用时显示 4 页。见下图。白色是当前页面。绿色表示页面可用。
希望我已经正确解释了所有内容并且这对您有用。让我知道。
