I have a little problem with pagination class of codeigniter
Here is my controller
function index()
{
$this->load->library('pagination');
$config['base_url'] = base_url().'index.php/books/index/';
$config['total_rows'] = $this->db->count_all('books');
$config['per_page'] = '5';
$config['full_tag_open'] = '<p>';
$config['full_tag_close'] = '</p>';
$this->pagination->initialize($config);
echo "Here";
//load the model and get results
$this->load->model('books_model');
$data['results'] = $this->books_model->get_books($config['per_page'],$this->uri->segment(3));
// load the HTML Table Class
$this->load->library('table');
$this->table->set_heading('Title');
// load the view
$this->load->view('books_view', $data);
}
and here is the view
<body>
<h1>Books</h1>
<?php echo $this->table->generate($results); ?>
<?php echo $this->pagination->create_links(); ?>
</body>
and the model
function get_books($num, $offset) {
$query = $this->db->get('books', $num, $offset);
return $query;
}
I setup my database, and routes (default->books) already but the page doesn't show anything. My database table is books.
I don't know if $config is a variable of your own class. If it is the global config, maybe your should set its parameters using $this->config->set_item function.
Furthermore, to avoid troubles like #Henesnarfel mentioned before, try to echo the number of results when you execute the query.
function index()
{
$this->load->library('pagination');
$this->config->set_item('base_url',base_url().'index.php/books/index/');
$this->config->set_item('total_rows',$this->db->count_all('books'));
// ECHO to make me sure that the query is succesfully done
echo("Found ".$this->db->count_all('books')." books");
$this->config->set_item('per_page','5');
$this->config->set_item('full_tag_open','<p>');
$this->config->set_item('full_tag_close','</p>');
$this->pagination->initialize($config);
echo "Here";
//load the model and get results
$this->load->model('books_model');
$data['results'] = $this->books_model->get_books($config['per_page'],$this->uri->segment(3));
// load the HTML Table Class
$this->load->library('table');
$this->table->set_heading('Title');
// load the view
$this->load->view('books_view', $data);
}

hi in this link you are not checking the search condition
$config['total_rows'] = $this->db->count_all_results('tbl_products');
change this line to
$config['total_rows'] = $this->db->count_all_results($search_term);
and write the proper query
$config['total_rows'] = $this->db->count_all_results('tbl_products');
Problem in the this files, u need write another query which will be collect result by search without offsets and limits.
For example
function search($text, $offset, $limits){
//this u do search
}
function count_search($text){
//This same logic with search but return Integer value for example
//return $this->db->query()->num_rows();
}
Hi I have implemented Pagination in PHP Code But it is not Working while clicking on the pagination links.It is displaying the same data for all the pages.Here is the code.
Controller:
class Testimonial extends CI_Controller {
function __construct() {
parent::__construct();
//here we will autoload the pagination library
$this->load->library('pagination');
}
public function index()
{
$this->load->model('testimonial_model');
$config = array();
$config["base_url"] = base_url('testimonial/index');
$config['total_rows'] = $this->db->count_all("testimonials");//here we will count all the data from the table
$config['per_page'] = 6;//number of data to be shown on single page
$config["uri_segment"] = 2;
$this->pagination->initialize($config);
$page = ($this->uri->segment(2)) ? $this->uri->segment(2) : 0;
$data["records2"] = $this->testimonial_model->get_all_testimonials($config["per_page"], $page);
$data["links"] = $this->pagination->create_links();//create the link for pagination
$data['mainpage'] = "testimonial";
$this->load->view('templates/template',$data);
}
Model:
class Testimonial_model extends CI_Model
{
function get_all_testimonials($limit, $start)
{
$this->db->limit($limit, $start);
$this->db->select('T.*');
$this->db->from('testimonials AS T');
$this->db->where(array('T.status'=>1));
$q = $this->db->get();
if($q->num_rows()>0)
{
return $q->result();

$data["links"] = $this->pagination->create_links();//create the link for pagination
$data['mainpage'] = "testimonial";
$this->load->view('templates/template',$data);
}
I cant comment so I just make this an answer,
Here
http://bootsnipp.com/snippets/featured/rounded-pagination
This is what I use in making my pagination! and there is alot more of it! I also use CI as my framework!
I put my problem, I created a table "comments" then I maked a controller which two functions are implemented, function for reading and the one other for insertion.
What I need now is to realize function for managing comments, ie beside each comments there is an options delete and modify.
So,I add a new function that I named manage (), then, to avoid some repetition I think keep read (used to list the comments) and using it into manage() then add these stufs(modify,delete) beside each comment.
But I don't know how to proceed?
I need your advice help!
<?php
class Site extends CI_Controller {

}
function index() {
$this->read();
// $this->add();
}

$this->load->library('pagination');

I am trying to get the pagination to work with codeigniter. But am getting the following errors
Severity: Notice
Message: Undefined offset: 0
Filename: controllers/group.php
And
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: views/group_list_view.php
Following is the code of my Model
public function get_list($userid)
{
$this->load->library('pagination');
$config['base_url'] = 'http://localhost/portal/index.php/group/index';
$config['total_rows'] =$this->db->where('UserId',$userid)->get('group')->num_rows();
$config['per_page'] = 10;
$config['num_links'] = 10;
$this->pagination->initialize($config);
$query['groups'] = $this->db->get('group', $config['per_page'], $this->uri->segment(3));
return $query;
}
Here is the code for my controller
class Group extends CI_Controller {
public function __constructor()
{
session_start();
parent::__constructor();
}
public function index()
{
if(!$this->session->userdata('userid'))
redirect('login');
$this->load->model('group_model');
$result = $this->group_model->get_list($this->session->userdata('$userid'));
//neither this works
data['groups'] = $result;
//nor this
$data['groups'] = $result[0];
$this->load->view('group_list_view', $data);
}
}
And this the code in view
foreach($groups as $group){
echo $group->GroupId;
}
Can anyone please guide me where am i doing it worng. Apparently no one else seems to have encountered any such problem. I followed the tutorial from net.tutsplus ditto but still facing the same issue. Please note i am new to PHP to be gentel :)
You need to write the code in controller not in model
public function index()
{
if(!$this->session->userdata('userid'))
redirect('login');
$this->load->library('pagination');
$config['base_url'] = 'http://localhost/portal/index.php/group/index';
$config['total_rows'] = // Use the same function to get the number of rows
$config['per_page'] = 10;
$config['num_links'] = 10;
$this->pagination->initialize($config);
$this->load->model('group_model');
$result = $this->group_model->get_list($this->session->userdata('$userid'));
data['groups'] = $result;
$this->load->view('group_list_view', $data);
}
Here:
$query['groups'] = $this->db->get('group', $config['per_page'], $this->uri->segment(3));
You're assing the query resultset to $query['group']
but in the controller you're doing
$data['groups'] = $result;
and then you iterate:
foreach($groups as $group){
You should be doing instead:
foreach($groups['groups'] as $group){
Since your original assignment in the model is to $query['groups'].
So, either you assing to $query in the model, or you iterate the correct array in the view (like I showed you above)

}
here, you are wrong
$newss=$this->load->model('NewsModel');
do it like this
$this->load->model('NewsModel'); //this line just loads model
$newss=$this->NewsModel->your_function_in_model(); //here you call function from models that you ve loaded
Check this line:
$newss = $this->load->model('NewsModel');
You need to call a model function here and not load the model again. I think it should be:
$newss = $this->NewsModel->get_paged_list();
Or, change the foreach to:
foreach($News1 as $news){ #$News1 from $News1 = $this->NewsModel->get_paged_list($this->limit, $offset)->result();
I think you don't know how load->model() works.
$this->load->model('NewsModel'); // will load NewsModel on NewsController
// you can call loaded model by $this->modelName
$newss = $this->NewsModel->get_paged_list(10, $i); // will call get_paged_list() on NewsModel and result will save on newss
There is no such function call in your code. Now you can do this foreach($newss as $news)
