分页在codeigniter中不起作用:( [英] pagination is not working in codeigniter :(
问题描述
我想在视图页面中显示2行作为输出.同样，当我单击以转到下一页时，它将显示接下来的2行，依此类推(总共共有8行) 桌子).但是，当我运行以下代码时，它将在视图页面中显示所有8行以及分页链接.我整天试图找到不这样做的实际原因 工作，但我的问题仍然没有解决.我在互联网上搜索相关查询的帮助，但没有用.最后，我在这里用我自己的话来解释 问题.我已经在代码中注释了几乎所有行.我正在自动加载库以进行分页，并在窗体和URL的帮助器中进行加载.如果真的我会很感激 有人帮我.预先感谢.
I want to display 2 rows in view page as an output. Again when i click on to go to the next page it will display 2 next rows and so on ( All together I have 8 rows in table). But when I run the following code it displays all 8 rows in the view-page along with pagination links. I tried whole day to find the actual reason for not working it but my problem is still unsolved. I searched for the help on internet with related query but it was of no use. Finalyy I am here with my own words to explain the problem. I've commented almost all the lines in my code. I am loading libraries in autoload for pagination and helper for form and url. I'll really be thankful if somebody help me out. Thanks in advance.
<?php
class ManageUser extends CI_Controller { // creating class for the controller
function index()
{
if($this->session->userdata('logged_in')) // checking users under session if he is already logged in
{
$this->load->model('admin/user'); // loading model . I am not using Datamapper.
$result = $this->user->view_user(); // getting response from the model and storing it to result
$total_rows = count($result); // counting number of rows countered ( its 8 in in my database )
//echo $total_rows;
if($result)
{
$data['users'] = $result;
$config['base_url'] = "http://192.168.0.102/project/index.php/admin/manageUser"; // this is the address where I am pointing the view page url
$config['total_rows'] = $total_rows; // Total numbers of rows assigned to pagination-config
$config['per_page'] = '2'; // I want to display 2 rows in 1 page
$config['uri_segment'] = '2';
$this->pagination->initialize($config); // initilizing the pagination-config
//$data['pagination'] = $this->pagination->create_links();
//$this->load->vars($data);
$this->load->view('admin/manageUser',$data); // Loading the page
}
//$this->load->view('admin/manageUser',$data);
}
else
{
redirect('admin/login'); // incase of faliured session user will be redirected to the login-page.
}
}
}
?>
以下代码来自于我的名为User
Following code is from my model named User
<?php
Class User extends CI_Model // extending the model
{
function __construct()
{
parent::__construct();
}
function view_user() // function which is loaded from controller
{
$query = $this -> db -> get('users'); //query to fetch all the information from the database
return $query->result(); // returning result to the Controller.
}
}
?>
最后这是我用来显示内容的查看页面.
And finally this is the view page I am using to display the content .
<!-- This is the view page -->
<?php if(isset($users)) { ?> <!-- Checking if user is set -->
<?php foreach($users as $user) { ?> <!-- running in a loop to accept all the value from the database and display it row wise -->
<td><?php echo $user -> us_display_name; ?></td> <!-- Displaying name -->
<td><?php echo $user -> us_first_name . " " . $user -> us_last_name; ?></td> <!-- Displaying first name and last name together -->
<td><?php echo $user -> us_email_id; ?></td> <!-- Displaying email-ID -->
<?php } } else { ?>
<tr> <td>No records found!</td>
<?php } ?>
<?php echo $this->pagination->create_links(); ?>
推荐答案
您正在从模型中获取所有用户.那不是你做的方式. 您的控制器应该是这样的:
You are getting all the users from the Model. That's not how you do it. Your controller should be something like this :
<?php
class ManageUser extends CI_Controller { // creating class for the controller
function index($offset)
{
if($this->session->userdata('logged_in')) // checking users under session if he is already logged in
{
$this->load->model('admin/user'); // loading model . I am not using Datamapper.
$perpage = 2;
$result = $this->user->view_user($offset,$perpage); // getting response from the model and storing it to result
$total_rows = $this->db->count_all('users');
if($result)
{
$data['users'] = $result;
$config['base_url'] = "http://192.168.0.102/project/index.php/admin/manageUser"; // this is the address where I am pointing the view page url
$config['total_rows'] = $total_rows; // Total numbers of rows assigned to pagination-config
$config['per_page'] = $perpage; // I want to display 2 rows in 1 page
$config['uri_segment'] = '2';
$this->pagination->initialize($config); // initilizing the pagination-config
//$data['pagination'] = $this->pagination->create_links();
//$this->load->vars($data);
$this->load->view('admin/manageUser',$data); // Loading the page
}
//$this->load->view('admin/manageUser',$data);
}
else
{
redirect('admin/login'); // incase of faliured session user will be redirected to the login-page.
}
}
}
?>
在模型中，您需要限制结果
And in the model you need to limit the result
<?php
Class User extends CI_Model // extending the model
{
function __construct()
{
parent::__construct();
}
function view_user($offset,$limit) // function which is loaded from controller
{
$query = $this -> db -> get('users',$perpage,$offset); //You dont fetch all the data from the database
return $query->result(); // returning result to the Controller.
}
}
?>
