我正在学习CI,而我最近的任务就是分页。所以我遵循了这个教程,因为它看起来相当不错,并且解释得很好。 Link
分页效果很好。现在我想在每个帖子下阅读更多内容,使每个帖子单独打开并附上完整描述。这也有效,但当我点击链接返回分页索引时,无论我点击哪个帖子,列表都从头开始。我不确定如何添加我希望返回链接带回来的页面,所以我只是在这里发帖,希望有人告诉我这太难了。
如果有人对我之后的事情感到困惑,请查看最后一个视图readmore_paginate。在其中,最后一个链接应该包含一个数字 到页面,但idk如何放或放在那里。
控制器
public function paginate()
{
$config = array();
$config['base_url'] = base_url()."welcome/paginate";
$config['total_rows'] = $this->blog_model->countPosts();
$config['per_page'] = 2;
$config['uri_segment'] = 3;
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0; //TERNARY OPERATOR (? = TRUE) (: = FALSE)
$data['results'] = $this->blog_model->fetchPosts($config['per_page'], $page);
$data['links'] = $this->pagination->create_links();
$this->load->view('header');
$this->load->view("p_content", $data);
$this->load->view('footer');
}
public function readMore_Paginate()
{
$id = $this->input->get('postid');
$data['post'] = $this->blog_model->getSpecificPost($id);
$this->load->view('header');
$this->load->view('readmore_paginate', $data);
$this->load->view('footer');

模型
public function countPosts()
{
return $this->db->count_all("Blogposts");
}
public function fetchPosts($limit, $start)

if($query->num_rows() > 0)
{
foreach ($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
