嗯，我已经到处搜索了，但仍然找不到解决我的问题的方法。我对 php 和 codeigniter 仍然很陌生，所以也许我已经错过了答案，但无论如何，这就是我想要做的。
这是我的控制器 (c_index.php) - 调用搜索函数并对结果数组执行分页。
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class C_index extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('m_search');
$this->load->library("pagination");
$this->load->library("table");
}
/** Index Page for this controller */
public function index()
{
if($this->session->userdata('logged_in')){
$this->load->view('v_user');
}
else{
$this->load->view('index');
}
}
public function search()
{
// start of search
$search_term = $this->input->post('word');
$books = $this->m_search->search_books($search_term);
// start of pagination
$config['base_url'] = "http://localhost/test/index.php/c_index/search";
$config['per_page'] = 5;
$config['num_links'] = 7;
$config['total_rows'] = count($books);
echo $config['total_rows'];
$this->pagination->initialize($config);
$data['query'] = array_slice($books,$this->uri->segment(3),$config['per_page']);
$this->load->view("index",$data);
}
}
这是我的视图（index.php） - 基本上只显示分页结果
<h3> Search Results </h3>
<!-- table -->
<table class="table table-condensed table-hover table-striped" id="result_table">
<tbody>
<?php
if(isset ($query)){
if(count($query)!=0){
foreach($query as $item){
echo "<tr><td>". $item['title'] ." by " .$item['author'] ."<br/></td></tr>";
}
echo $this->pagination->create_links();
}
else
{
echo "No results found for keyword ' ". $this->input->post('word')." ' .";
}
}
else
{
echo "Start a search by typing on the Search Bar";
}
?>
</tbody>
</table>
我的模型（m_search.php） - 基本上搜索数据库并返回结果数组。
<?php
类 M_search 扩展 CI_Model{
function search_books($search_term='default')
{
$filter = $this->input->post('filter');
//echo $filter;
if($filter == 'title')
{
//echo 'title';
$this->db->select('*');
$this->db->from('book');
$this->db->like('title',$search_term);
// Execute the query.
$query = $this->db->get();
return $query->result_array();
}else if($filter == 'author')
{
//echo 'author';
$this->db->select('*');
$this->db->from('book');
$this->db->like('author',$search_term);
// Execute the query.
$query = $this->db->get();
return $query->result_array();
}else if($filter == 'type')
{
//echo 'type';
$this->db->select('*');
$this->db->from('book');
$this->db->like('book_type',$search_term);
// Execute the query.
$query = $this->db->get();
return $query->result_array();
}else if($filter == 'status')
{
//echo 'status';
$this->db->select('*');
$this->db->from('book');
$this->db->like('book_status',$search_term);
// Execute the query.
$query = $this->db->get();
return $query->result_array();
}else
{
//echo 'all';
$this->db->select('*');
$this->db->from('book');
$this->db->like('book_status',$search_term);
$this->db->or_like('book_type',$search_term);
$this->db->or_like('author',$search_term);
$this->db->or_like('title',$search_term);
// Execute the query.
$query = $this->db->get();
return $query->result_array();
}
}
}
现在我的问题是保留分页结果。
第一页很好，但每当我单击页面链接时，表格上的结果就会显示整个数据库，而不仅限于我的搜索结果。
我在某处读到，我需要使用会话来保留我的 search_term，以便在我切换页面时它可以工作，但我不知道把它放在哪里。
任何意见或建议将不胜感激。谢谢。
