我的控制器：
public function search()
{
$data['category_name'] = $this->model_products->dis_category();
$this->load->view('layout/header', $data);
$keyword = ''; // default when no term in session or POST
if ($this->input->post('search'))
{
// use the term from POST and set it to session
$keyword = $this->input->post('search');
$this->session->set_userdata('keyword', $keyword);
}
elseif ($this->session->userdata('keyword'))
{
// if term is not in POST use existing term from session
$keyword = $this->session->userdata('keyword');
}
$data['otherproduct'] = $this->model_products->other_prodects();
$data['otherproduct2'] = $this->model_products->other_prodects2();
//Pagination init
$config['base_url'] = base_url().'search/';
$config['total_rows'] = $this->model_products->num_rows($keyword);
$config['per_page'] = 10;
$config['uri_segment'] = 2;
$config['num_links'] = 2;
//custom pigination
$config['full_tag_open'] = '<ul class="tsc_pagination tsc_paginationA tsc_paginationA01">';
$config['full_tag_close'] = '</ul>';
$config['prev_link'] = 'Prev';
$config['prev_tag_open'] = '<li>';
$config['prev_tag_close'] = '</li>';
$config['next_link'] = 'Next';
$config['next_tag_open'] = '<li>';
$config['next_tag_close'] = '</li>';
$config['cur_tag_open'] = '<li class="current"><a href="#">';
$config['cur_tag_close'] = '</a></li>';
$config['num_tag_open'] = '<li>';
$config['num_tag_close'] = '</li>';
$config['first_tag_open'] = '<li>';
$config['first_tag_close'] = '</li>';
$config['last_tag_open'] = '<li>';
$config['last_tag_close'] = '</li>';
$config['first_link'] = 'First';
$config['last_link'] = 'Last';
$this->pagination->initialize($config);
$data['search'] = $this->model_products->SearchResult($config['per_page'],$this->uri->segment(2,0),$keyword);
$this->load->vars($data);
$this->load->view('layout/resault', $data);
$this->load->view('layout/footer');
}
我的模特：
function SearchResult($perPage,$uri,$keyword)
{
$this->db->select('*');
$this->db->like('pro_part',$keyword);
$this->db->or_like('pro_description',$keyword);
$this->db->or_like('pro_name',$keyword);
$this->db->order_by('pro_part','asc');
$getData = $this->db->get('products', $perPage, $uri);
return $getData->result_array();
}
function num_rows($keyword){
$this->db->select('*');
$this->db->where_in("'pro_part' like '%$keyword'");
$this->db->or_where_in("'pro_name' like '%$keyword'");
$query = $this->db->get('products');
return $query->num_rows();
}
我的观点：
特色产品＆lt; / span＆gt;＆lt; / h2＆gt; - ＆gt; “session-＆gt; userdata（'word'）;？＆gt;”的结果
<?php if(count($search) > 0):?> <?php foreach ($search as $row) :?> <div class="span13 product"> <div> <figure> <?php if(!empty($row['pro_image'])): ?> <a href="<?= site_url("view")."?productdetail=".$row['pro_id'];?>"><imgsrc =“template / images / products /”alt =“image”/＆gt;

我的问题是结果分页计数数据库中的所有行，不受post方法限制。
答案 0 :(得分：0)
将你的模型where_in更改为where，where_in用于数组，在你的情况下将导致null，因此它不使用条件
function num_rows($keyword){
$this->db->select('*');
$this->db->where_in("'pro_part' like '%$keyword'");
$this->db->or_where_in("'pro_name' like '%$keyword'");
$query = $this->db->get('products');
return $query->num_rows();
}
到
function num_rows($keyword){
$this->db->select('*');
$this->db->where("'username' like '%$keyword%'");
$this->db->or_where("'full_name' like '%$keyword%'");
$query = $this->db->get('cms_users');
//$query1 = $this->db->last_query();
//print_r($query1);
return $query->result_array();
}
