Pagination and segment URIs - mboehmlaender - 07-06-2020
I began writing a webapp in Codigniter 4 and currently, i'm stuck with the pagination.
I created a controller, a model an a view to retrieve database entries für usergroups and used CI's built-in pagination-library.
UsergroupsModel:
Code:
<?php namespace App\Models;
use CodeIgniter\Model;
class UsergroupsModel extends Model{
protected $table = 'roles';
protected $allowedFields = [];
protected $beforeInsert = ['beforeInsert'];
protected $beforeUpdate = ['beforeUpdate'];
public function getGroups(){
$db = \Config\Database::connect();
$builder = $db->table('roles');
$query = $builder->get();
$results = $query->getResultArray();
return $results;
}
}Controller (Usergroups):
Code:
<?php namespace App\Controllers;
use App\Models\UsergroupsModel;
class Usergroups extends BaseController
{
public function index()
{
//Helper laden
helper(['form','template','userrights']);
$data = [];
$data['template'] = get_template();
$data['info'] = [
"active" => "menu_dash",
"title" => "Dashboard",
"icon" => "fab fa-fort-awesome fa-lg",
"sub" => "Frontend",
];
//Check Permissions
$data['userrights'] = get_userrights(session()->get('id'));
if($data['userrights'][1] == 1)
{
foreach($data['userrights'] as $key => $value){
$data['userrights'][$key] = '1';
}
}
else
{
$data['userrights'] = $data['userrights'];
}
$model = new UsergroupsModel;
$model->getGroups();
$pager = \Config\Services::pager();
$data['usergroups'] = $model->paginate(5);
$data['pager'] = $model->pager;
//Create Views
echo view($data['template'].'/templates/header', $data);
echo view($data['template'].'/backend/navigation');
echo view($data['template'].'/templates/sidebar');
echo view($data['template'].'/backend/usergroups');
echo view($data['template'].'/templates/footer');
}
//--------------------------------------------------------------------
}In the view, i got my pagination by using
Code:
<?= $pager->links() ?>The default pagination works fine, but i get an URI like https://DOMAIN.DE/usergroups?page=2
In the official Codeigniter 4 docs for the pagination, you can find the following:
Quote:Specifying the URI Segment for Page It is also possible to use a URI segment for the page number, instead of the page query parameter. >Simply specify the segment number to use as the fourth argument. URIs generated by the pager would then >look like https://domain.tld/model/[pageNumber] instead of https://domain.tld/model?page=[pageNumber].:So in my controller i changed
::
$users = $userModel->paginate(10, ‘group1’, null, 3); Please note: $segment value cannot be greater than the number of URI segments plus 1.
Code:
$data['usergroups'] = $model->paginate(5);to
Code:
$data['usergroups'] = $model->paginate(5,'test',0,2);and in the view i added 'test' as a parameter.
Code:
<?= $pager->links('test') ?>In the Routes i added
Code:
$routes->get('usergroups/(:num)', 'Usergroups::index/$1');and in the Controller i changed the index-function to
Code:
public function index($segment = null)The URIs generated from the pagination now look like this:
https://DOMAIN.DE/usergroups/2
but it does not change anything in the entries and the pagination itself alway sticks to page 1.
I think, i can not use CI's built in library when switching to segment-URIs and thus i need to create a manual pagination.
Can somebody help me to fix this problem?
RE: Pagination and segment URIs - jreklund - 07-06-2020
By the looks of things, there are a bug in 4.0.3, as the development version have changed how that feature works. And as of now (for you) it's broken. You need to load it manually for now.
https://codeigniter.com/user_guide/libraries/pagination.html#setting-page-manually
PHP Code:
$data['usergroups'] = $model->paginate(5, 'test', (int) $segment);
RE: Pagination and segment URIs - mboehmlaender - 07-06-2020
Great, that did the trick!
In the controller, i changed the function to
Code:
public function index($page = 1)and the $data['usergroups']
to
Code:
$data['usergroups'] = $model->paginate(5, 'test', $page, 2);Works like a charm

Great that it worked out for you, don't have an release date for then this is fixed and you don't need to manually assign it anymore.
