I am trying to create pagination using CodeIgniter. It displays links fine, but when I click the links it shows 404 error. How to solve this?
控制器示例.php
class example extends CI_controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Donor_model');
$this->load->library('pagination');
$this->load->helper('url');
$this->load->library('form_validation');
}
public function get_details()
{
$config['base_url'] = base_url('info');
$config['total_rows'] = $this->Donor_model->count();
$config['per_page'] = 10;
$config['uri_segment'] = 3;
$choice = $config['total_rows']/$config['per_page'];
$config['num_links'] = round($choice);
$this->pagination->initialize($config);
$page =($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data['data'] = $this->Donor_model->get_data([], [],$config['per_page'],$page);
$data['links'] = $this->pagination->create_links();
$this->load->view('admin/info',$data);
}
}
模型(Example_Model.php)
Example_Model 类，它扩展了 My_Model 类:
class Donor_model extends MY_Model
{
protected $table = 'donors';
public function __construct()
{
//call the MY_Model construtor
parent::__construct();
}
public function get_data($where, $fields,$limit, $start)
{
return $this->get($where,$fields , $limit, $start);
}
public function count_data()
{
return $this->count();
}
模型 (My_Model.php)
class MY_Model extends CI_Model
{
protected $table = NULL;
// protected $table_fields = [];
// protected $fillable = [];
// protected $protected = [];
protected $primary_key = 'id';
function __construct()
{
parent::__construct();
$this->load->database();
}
/**
* Return all table contents
* @param array $where ,$fields, $limit
* @return array
*defualt $sortOrder = dsc
*/
// public function get(array $where = NULL, $limit = 1000, $sortOrder = 'dsc')
public function get(array $where = NULL, array $fields = NULL, $limit = NULL, $start = NULL)
{
$query = NULL;
// return all records with all fields from table
if($fields == NULL and $where == NULL){
$this->db->limit($limit, $start);
$query = $this->db->get($this->table);
if ($query->num_rows() > 0 ) {
return $query->result();
}
else
return false;
}
// rteurn all records with only my fields
elseif($fields != NULL and $where == NULL){
$this->db->limit($limit, $start);
$this->db->select($fields);
$query = $this->db->get($this->table);
if ($query->num_rows() > 0)
return $query->result();
else
return false;
}
// return all records through condition
elseif($fields == NULL and $where != NULL){
$this->db->limit($limit, $start);
$query = $this->db->get_where($this->table, $where);
if ($query->num_rows() > 0)
return $query->result();
else
return false;
}
// return all records with only my fields through condition
else{
$this->db->limit($limit, $start);
$this->db->select($fields);
$query = $this->db->get_where($this->table, $where);
if ($query->result() > 0 )
return $query->result();
else
return false;
}
}
public function count()
{
return $this->db->count_all($this->table);
}
}

<?php foreach ($data as $key => $row) {

推荐答案
你确定你已经从你的 url 中删除了 index.php 吗?此外，如果您重新定义了路线，以便信息"指向example/get_details"(正如我从您的评论中看到的...)，那么 $config['uri_segment'] 应该设置为2"，而不是3".
Did you make sure you've removed index.php from your url?
Also, if you've redefined the route so that "info" points to "example/get_details" (as I see from your comments...), then the $config['uri_segment'] should be set to "2", and not "3".
