i have a problem with the kohana pagination. i have made a method for paginating elements from the database, (let's say 3 on a page), but, (though the pagination links are there), the pagination is not actually done, meaning i always get listed all the elements of the query.
the code i am using:
in a helper:
public function come_paginate_users(){
$count = Model::factory('user')->count_all(); //echo $count; exit();
$pagination = Pagination::factory(array(
'total_items' => $count,
'items_per_page' => 2,
'auto_hide' => TRUE,
));
$results = Model::factory('user')->order_by('user_id','ASC')->limit($pagination- >items_per_page)->offset($pagination->offset)->find_all();//->execute();
$page_links = $pagination->render();
return $pagination;
}
in the controller:
$pagination = #helper_utilities::come_paginate_users();
$this->view->pagination = $pagination;
and in the view:
<? echo 'Classic style: '.$pagination;?>
but... the pagination is not working. any idea why? thank you!
Actually, You need to return $page_links (wich is rendered html) and $result instead of $pagination object in your come_paginate_users() method
Maybe total_items < items_per_page and auto_hide hides the pagination? Try to set auto_hide to FALSE

I have a form in Laravel. I used pagination in this form and search option too. Pagination works fine when I didn't search anything. If I search something which has records more than 10 (my pagination record limit is 10), it shows result perfectly in first page but in second page or third page it shows the records of whole database. It's ignore the search criteria.
Controller Code:
public function index()
{
if (Input::has('invoiceNumber')) {
$invoiceNumber = Input::get('invoiceNumber');
$invoices = Invoice::where('invoiceNumber','like', '%'.$invoiceNumber.'%')->orderBy('date','desc')->paginate(10);
} elseif (Input::has('client')) {
$client = Input::get('client');
$invoices = Invoice::where('client','like', '%'.$client.'%')->orderBy('date', 'desc')->paginate(10);
} elseif (Input::has('startDate') && Input::has('endDate')) {
$startDate = Input::get('startDate');
$endDate = Input::get('endDate');
$invoices = Invoice::whereBetween('date', [$startDate, $endDate])->orderBy('date', 'desc')->paginate(10);
} elseif (Input::has('startDate')) {
$startDate = Input::get('startDate');
$invoices = Invoice::where('date', $startDate)->orderBy('date', 'desc')->paginate(10);
} elseif (Input::has('endDate')) {
$endDate = Input::get('endDate');
$invoices = Invoice::where('date', $endDate)->orderBy('date', 'desc')->paginate(10);
} else {
$invoices = DB::table('invoices')
->join('vehicles', 'invoices.vehicle', '=', 'vehicles.registration')
->select(
'invoices.*',
'vehicles.brand',
'vehicles.model',
'vehicles.seat',
'vehicles.remarks'
)
->orderBy('date', 'desc')
->paginate(10);
}
return view('invoice.index',compact('invoices'));
}
After performing search my URL look like this:
http://my-site.com/invoice?invoiceNumber=&client=&startDate=2016-01-01&endDate=2016-02-08
After this search when I click on page 2, the URL become this:
http://my-site.com/invoice?page=2
Try to use this bellow code (change as per your requirement)
return view('invoice.index')->withInvoices($invoices->appends(Input::except('page'));
Hope it's working for you...
In your view file, the render has to be like given below:
{!! $invoices->appends(Input::except('page'))->render() !!}
Simply use this on the result page.Pagination will be automatically visible at the bottom of the page
{!! $invoices->render() !!}
I'm new to cakephp2 and I need some help here.
The problem is that I have a view that displays a list of items from the database and there is a pagination button below. Instead of moving to the 2nd page by using the pagination, I want to have a single button that will allow you to display(append)10 more data list. But I'm not sure how it is called and how to implement it. Sorry for my bad explanation.
I think, you can play with limit parameter.
Somethink like this:
// in controller
<?php
function items() {
$limit = array_key_exists('n', $this->request->query) ? (int) $this->request->query['n'] : 10;
// some security check you need to add
$this->paginate = array(
'limit' => $limit
);
$items = $this->paginate($this->YourModel);
// some other code
$this->set(array(
'items' => $items,
'next_limit' => $limit + 10
));
}
?>
<?php
// in view file
// items output
foreach($items as $item) ...
// more button
echo "<a href='".$this->here."?n=".$next_limit."'>More</a>";
?>
I am trying to integrate pagination in kohana, but don't know how to integrate it. Following is the controller function
public function action_index() {
//setup the model and view
$_users = Model::factory('users');
$us = $_users->get_users();
$view = View::factory('users/index')->bind('user_list', $us);
$this->template->set('content',$view);
}
How can i add pagination in this function?
I found some code for pagination but couldn't integrate it. This is the function i found
$this->pagination = new Pagination(array(
'base_url' => 'users/index/',
'uri_segment' => 'page',
'total_items' => count($items->get_item_count())
Please help me
EDIT:
I tried something like
public function action_index(){
$query = DB::select()->from('user');
// count number of users
$total_users = count($query);;
// set-up the pagination
$pagination = Pagination::factory(array(
'total_items' => $total_users,
'items_per_page' => 10, // this will override the default set in your config
));
// select rows using pagination's limit&offset
$users = $query->offset($pagination->offset)->limit($pagination->items_per_page)->execute();
$view = View::factory('users/index')->bind('user_list', $users)->bind('pagination', $pagination);
$this->template->set('content',$view);
}
Now no error found but pagination not showing up. Used shadowhand's pagination module suggested by #DanielThompson
I use shadowhand's pagination module which supports Kohana 3+, just make sure you grab the same branch as your Kohana version, then add it to your modules directory.
Update your application/bootstrap.php file:
Kohana::modules(array(
// ...
'pagination' => MODPATH.'pagination'
));
Copy modules/pagination/config/pagination.php to application/config/pagination.php
In your controller action (e.g. users):
// count number of users
$total_users = ORM::factory('User')->count_all();
// set-up the pagination
$pagination = Pagination::factory(array(
'total_items' => $total_users,
'items_per_page' => 10, // this will override the default set in your config
));
// get users using the pagination limit/offset
$users = ORM::factory('User')->offset($pagination->offset)->limit($pagination->items_per_page)->find_all();
// pass the users & pagination to the view
$this->view->bind('pagination', $pagination);
$this->view->bind('users', $users);
In your view:
// loop over users
foreach($users as $user) {
// ...
}
// display pagination view using
echo $pagination;
The module comes with two views: basic or floating which is set in the config file. You could also create a custom one for your application.
I have a module Search in my ZF2 application. The user fills in a search form out and gets a list of courses.
Now I'm adding the pagination to the module. The paginator is basically working: I can retrieve data over it and the pagination is displayed correctly (pagelinks 1-7 for 70 found courses with the dafault setting 10 items per page).
But it's still not usable. When I click on a pagelink, the form POST data is lost. I know -- it cannot work the way, how I implemented it (see the code below). But I have no idea, how to do it correctly, in order to eep checking the form data and nonetheless be able to use pagination.
That is my code:
Table class Search\Model\CourseTable
class CourseTable {
...
// without pagination
// public function findAllByCriteria(CourseSearchInput $input) {
// with pagination
public function findAllByCriteria(CourseSearchInput $input, $pageNumber) {
...
$select = new Select();
$where = new Where();
$having = new Having();
...
// without pagination
// $resultSet = $this->tableGateway->selectWith($select);
// return $resultSet;
// with pagination
$adapter = new \MyNamespqce\Paginator\Adapter\DbSelect($select, $this->tableGateway->getAdapter());
$paginator = new \Zend\Paginator\Paginator($adapter);
$paginator->setCurrentPageNumber($pageNumber);
return $paginator;
}
...
}
Search\Controller\SearchController
class SearchController extends AbstractActionController {
public function searchCoursesAction() {
$form = $this->getServiceLocator()->get('Search\Form\CourseSearchForm');
$request = $this->getRequest();
if ($request->isPost()) {
$courseSearchInput = new CourseSearchInput();
$form->setInputFilter($courseSearchInput->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$courseSearchInput->exchangeArray($form->getData());
// without pagination
// $courses = $this->getCourseTable()->findAllByCriteria($courseSearchInput);
// with pagination
$page = $this->params()->fromRoute('page');
$paginator = $this->getCourseTable()->findAllByCriteria($courseSearchInput, $page);
} else {
$paginator = null;
}
} else {
$paginator = null;
}
return new ViewModel(array(
'form' => $form,
// without pagination
// 'courses' => $courses,
// with pagination
'paginator' => $paginator,
'cities' => ...
));
}
...
}
How to get it working?
I also have the same problem, and I have solved it. But this is not good way. May be the idea will help you.
I solved it as follow: (Search pagination for Zend tutorial album module)
I build two action in controller named "search" and "index".
Whenever the search form submitted, it always post the value to search action. Search action build the url with search parameters, and redirect to index to disply search result.
And when the pagination links clicked, then posted values are passed through url. So whenever index action ask for search parameters, it always get the values in same format.
I defined route as follows:
'album' => array(
'type' => 'segment',
'options' => array(
'route' => '/album[/:action][/:id][/page/:page][/order_by/:order_by][/:order][/search_by/:search_by]',
'constraints' => array(
'action' => '(?!\bpage\b)(?!\border_by\b)(?!\bsearch_by\b)[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
'page' => '[0-9]+',
'order_by' => '[a-zA-Z][a-zA-Z0-9_-]*',
'order' => 'ASC|DESC',
),
'defaults' => array(
'controller' => 'Album\Controller\Album',
'action' => 'index',
),
),
),
There is a parameter named "search_by", which will keep all search parameters as a json string. This is the point, which is not good I know, but have not find any other way yet.
"Search" action build this string as -
public function searchAction()
{
$request = $this->getRequest();
$url = 'index';
if ($request->isPost()) {
$formdata = (array) $request->getPost();
$search_data = array();
foreach ($formdata as $key => $value) {
if ($key != 'submit') {
if (!empty($value)) {
$search_data[$key] = $value;
}
}
}
if (!empty($search_data)) {
$search_by = json_encode($search_data);
$url .= '/search_by/' . $search_by;
}
}
$this->redirect()->toUrl($url);
}
And next index action decode the string, do necessary action, and also send the json string to view.
public function indexAction() {
$searchform = new AlbumSearchForm();
$searchform->get('submit')->setValue('Search');
$select = new Select();
$order_by = $this->params()->fromRoute('order_by') ?
$this->params()->fromRoute('order_by') : 'id';
$order = $this->params()->fromRoute('order') ?
$this->params()->fromRoute('order') : Select::ORDER_ASCENDING;
$page = $this->params()->fromRoute('page') ? (int) $this->params()->fromRoute('page') : 1;
$select->order($order_by . ' ' . $order);
$search_by = $this->params()->fromRoute('search_by') ?
$this->params()->fromRoute('search_by') : '';
$where = new \Zend\Db\Sql\Where();
$formdata = array();
if (!empty($search_by)) {
$formdata = (array) json_decode($search_by);
if (!empty($formdata['artist'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('artist', '%' . $formdata['artist'] . '%')
);
}
if (!empty($formdata['title'])) {
$where->addPredicate(
new \Zend\Db\Sql\Predicate\Like('title', '%' . $formdata['title'] . '%')
);
}
}
if (!empty($where)) {
$select->where($where);
}
$album = $this->getAlbumTable()->fetchAll($select);
$totalRecord = $album->count();
$itemsPerPage = 2;
$album->current();
$paginator = new Paginator(new paginatorIterator($album));
$paginator->setCurrentPageNumber($page)
->setItemCountPerPage($itemsPerPage)
->setPageRange(7);
$searchform->setData($formdata);
return new ViewModel(array(
'search_by' => $search_by,
'order_by' => $order_by,
'order' => $order,
'page' => $page,
'paginator' => $paginator,
'pageAction' => 'album',
'form' => $searchform,
'totalRecord' => $totalRecord
));
}
All the sorting and paging url contain that string.
If you know all the searching paarameters before, then you can define that at route, and pass like the same way without json string. As I have to build a common search, I have build a single string.
Source code for "Album search" is available in git hub at https://github.com/tahmina8765/zf2_search_with_pagination_example.

#Sam & #automatix in the question comments are both right. My suggestion (though I'm looking for a simpler alternative) is to construct a segment route, which covers all of the options that you're likely to need and start with a standard form POST request.
Then, after the request is validated, pass the form data to the paginationControl helper as follows:
$resultsView = new ViewModel(array(
'paginator' => $paginator,
'routeParams' => array_filter($form->getData())
));
Then, in your view template, set the route parameters in the paginationControl view helper:
<?php echo $this->paginationControl($paginator, 'Sliding', 'paginator/default',
array('routeParams' => $routeParams)
) ?>
I've used array_filter here because it's a really simple way of removing any element from the form data that's null, empty or so on. That way you don't pass in extra data that you don't need.
Consider the following Silverstripe page class
<?php
class Page extends SiteTree{
static $has_many = array('OtherDataObjects' => 'DataObjectClass');
public function getSearchContext() {
$fields = new FieldSet(
new TextField('Title', 'Tour'),
new DropdownField('OtherDataObjects', 'Other Data Object', array('data', 'value')
);
$filters = array(
'Title' => new PartialMatchFilter('Title'),
'OtherDataObjects' => new PartialMatchFilter('OtherDataObjects.Title')
);
return new SearchContext(
'Page',
$fields,
$filters
);
}
}
Adding this search form to a front-end form and posting a search form always results in a [User Error] with a SQL error containing something like this at the end.
AND ("DataObjectClass_Live"."DataObjectClass_Live" LIKE 'title') ORDER BY "Sort" LIMIT 25 OFFSET 0 Table 'database DataObjectClass_Live' doesn't exist
My searchcontext search throws up an error each time I try to run a search on a has_many relationship. The versioned extension seems to be the culprit because it adds _live to all tables regardless whether the baseclass has the versioned extension or not I get the same error in SilverStripe versions 2.4.x and the latest 3.0.x versions.
Any help or pointers will be appreciated.
maybe try using an sqlQuery. something like
function SearchResults() {
$select = array('*');
$from = array('OtherDataObjects');
$where = array('OtherDataObjects:PartialMatch' => '%' . $data['Title'] . '%');
$sqlQuery = new SQLQuery($select, $from, $where);
$results = $sqlQuery->execute();
return $results;
}
$data['Title'] is to be the value from the search textbox
