为什么分页后在view里显示不出首页和尾页呢

pets-queen · 发表于 2012-6-21 16:21:37

PHP复制代码

function lists() {
$this->load->library('pagination');
$this->load->model('Blog_model');
$config['base_url'] = base_url() . 'index.php/blog/lists';
$config['total_rows'] = $this->Blog_model->getBlogs()->num_rows();
$config['per_page'] = '5';
$config['first_link'] = '首页';//这两条就是显示不来的
$config['last_link'] = '尾页';//
$config['full_tag_open'] = '<code>';
$config['full_tag_close'] = '</code>';
$this->pagination->initialize($config);
$data['result'] = $this->Blog_model->pages($config['per_page'],$this->uri->segment(3));
$this->load->library('table');
$this->table->set_heading('标题','发布时间');
$this->load->view('list',$data);
}

复制代码

HTML复制代码

<div id="main">
<table style="border-collapse: collapse;margin-left: 20px;margin-top: 10px">
<?php foreach($result->result_array() as $row): ?>
<tr>
<td><?php echo anchor('blog/cont/' . $row['id'],$row['title']); ?></td>
</tr>
<?php endforeach;?>
</table>
<div style="margin-top:330px;margin-left:20px;"><?php echo $this->pagination->create_links(); ?></div>
</div>

显示的就是这样

ci里面分页类问题。
你到第三页的时候，应该就出来了。

pets-queen · 发表于 2012-6-21 17:49:09

还是显示不出

siek · 发表于 2012-6-21 17:54:15

一直下一页，就没一个成功出来的？

pets-queen · 发表于 2012-6-21 17:54:18

我知道了，如果记录少的话，就不会出来的

嗯。其实吧，这是ci分页类存在的一个瑕疵问题。
我以前也遇到过一个。
给你一个修改过了的我一直在用的分页类吧。

我觉得这不应该算瑕疵，我觉得这是风格问题，老外的分页风格就是这样，只能说不符合国情。

是的 CI没借鉴Wordpress的分页就应该知足了
