I want to paginate search results using Zend_Paginator. So I pass my data to a paginator instance:
$paginator = new Zend_Paginator (
new Zend_Paginator_Adapter_DbSelect ( $data )
);
Data is returned this way
public function getData($idArray){
$db = Zend_Db_Table::getDefaultAdapter();
$selectProgramme = new Zend_Db_Select($db);
$selectProgramme->from('programme')
->order('id DESC')
->where('id IN(?)', $idArray);
return $selectProgramme;
}
$idArray is provided by my search implementations. This all works great and I get the correct data and pagination links displayed.
However I can't paginate the result because the pagination links are not valid. So normal pagination would have following link:
mysite.de/home/index/page/1
in search I now have
mysite.de/home/search/page/1
This does not work. Any suggestions how to implement search pagination?
EDIT: I have a HomeController with two actions, index and search action. IndexAction displays all data and I can paginate it.
public function indexAction(){
//...
$paginator = new Zend_Paginator(
new Zend_Paginator_Adapter_DbSelect($data)
);
$paginator->setItemCountPerPage(16)
->setPageRange(20)
->setCurrentPageNumber($this->_getParam('page', 1));
$this->view->data = $paginator;
}
The searchActions handles the search process:
public function searchAction(){
$response = $solr->search($this->getRequest()->getParam('search', null));
//...if items found get the data exactly the same way as in the
// index action, using Zend_Paginator_Adapter_DbSelect
$paginator = new Zend_Paginator(
new Zend_Paginator_Adapter_DbSelect($data)
);
$paginator->setItemCountPerPage(16)
->setPageRange(20)
->setCurrentPageNumber($this->_getParam('page', 1));
$this->view->data = $paginator;
}
So like you see in the search action there is a problem with the search process when I paginate. I need to decide somehow if to search or to paginate. Any suggestions on that?
Since search required the search parameter pagination will fail because when paginating the the search parameter is null.
$sreq = $this->getRequest()->getParam('search', null);
So we need to pass this parameter whenever we paginate our search. I solve this using Zend_Session:
//get search param
$sreq = $this->getRequest()->getParam('search', null);
//store search param in session for pagination
$search = new Zend_Session_Namespace('PSearch');
if($sreq != null){
$search->psearch = $sreq;
}else{
$sreq = $search->psearch;
}
I have this at the top of my searchAction and everything works.
Not sure I understand, but is your problem that the page parameter from the url is not making it's way to the Paginator - e.g. regardless of what page you are on, it is always showing the first 20 results?
If so, have you tried manually setting the page on the paginator:
$page = $this->_getParam('page', 1);
$paginator->setCurrentPageNumber($page);
public function search()
Are you sure that you didn't mistyped here? Should be
public function searchAction()
You put your search data into $response but create paginator instance using $data (which is null)

I'm using ZendFramework 2 and TableGateway which is fine for normal select statements. But I can't seem to find how to get a max of a column using ZendFramework 2 select.
My select should look something like
SELECT MAX( `publication_nr` ) AS maxPubNr FROM `publications`
and my code looks like:
use Zend\Db\TableGateway\TableGateway;
class PublicationsTable
{
protected $tableGateway;
...
public function getMaxPubicationNr()
{
$rowset = $this->tableGateway->select(array('maxPubNr' => new Expression('MAX(publication_nr)')));
$row = $rowset->current();
if (!$row) {
throw new \Exception("Could not retrieve max Publication nr");
}
return $row;
}
If you look at the TableGateway you will notice the parameters for the Select method are actually passed to the Where part of the Query, which is making your query incorrect.
You need to modify the Select Object directly as the TableGateway won't give you any proxy methods to do this.
You could try something like this:
public function getMaxPubicationNr()
{
$select = $this->tableGateway->getSql()->select();
$select->columns(array(
'maxPubNr' => new Expression('MAX(publication_nr)')
));
// If you need to add any where caluses you would need to do it here
//$select->where(array());
$rowset = $this->tableGateway->selectWith($select);
$row = $rowset->current();
if (!$row) {
throw new \Exception("Could not retrieve max Publication nr");
}
return $row;
}
I've not tested it, but that should just about get you there :)
You will probably bump into another issue though, and that will be due to the TableGateway trying to build you an object from the result, but you aren't bringing back a full row to build an object, you're just bringing back a single Column.
I would just add use the Db/Select objects to do this and not bother with the GateWay to be honest, I don't think it's supposed to be used like this.
I use Zend framework to build the forms, I want to make the edit action, since the user click on edit, the form appears with users data, how can I set the data to the form which is built dynamically??
$form->populate($data);
where $data is an array of key value pairs containing your data.
$form = new Zend_Form;
if ($this->_request->isPost()) {
//to just populate
$form->populate($this->_getAllParams());
//or auto populate during validation
if ($form->isValid($this->_getAllParams()) {
//do stuff if valid
}
}
I know that ZF maunal is pretty messy and not everything is clear, but I think forms are explained pretty nice (with examples). You should research more by yourself.
http://framework.zend.com/manual/en/zend.form.html
$Menu = new Admin_Model_DbTable_Menu();
$row = $Menu->fetchRow($Menu->select()->where('id = ?', $id));
$Addmenu = new Admin_Form_Addmenu();
$Addmenu->populate($row->toArray());
Can anyone tell me how to format the query below correctly in my controller.
Currently it gives me nothing in my FilteringSelect. However if I change it to >= I get back all the kennelIDs which is incorrect also but at least I'm getting something.
I've tested that the session variable is set and can confirm that there are kennels with the matching capacity.
// Create autocomplete selection for the service of this booking
public function servkennelAction()
{
$sessionKennelBooking = new Zend_Session_Namespace('sessionKennelBooking');
// disable layout and view rendering
$this->_helper->layout->disableLayout();
$this->getHelper('viewRenderer')->setNoRender(true);
// get list of grooming services for dogs from the table
$qry= Doctrine_Query::create()
->from('PetManager_Model_Kennels k');
//This should be set by default and narrows down the search criteria
if(isset($sessionKennelBooking->numPets)){
$b=(int)$sessionKennelBooking->numPets;
$qry->addWhere('k.capacity = ?','$b');
}
$result=$qry->fetchArray();
//generate and return JSON string using the primary key of the table
$data = new Zend_Dojo_Data('kennelID',$result);
echo $data->toJson();
}
Many thanks in Advance.

I think that addWhere condition is wrong. It has to be:
$qry->addWhere('k.capacity = ?', $b);
i.e. $b without quotes.
I've been using Zend Framework for a few months now. So, my knowledge is pretty good but I'm not quite an expert yet. I am trying to use zend_lucene with zend_paginator and so far not successful. I am able to use zend_lucene and index data successfully by itself and able to do use zend_paginator when querying the database, but I can't seem to combine the two. Here is a sample of what I am doing:
try {
$searchresults = $index->find($lucenequery);
}
catch (Zend_Search_Lucene_Exception $e) {
echo "Unable {$e->getMessage()}";
}
$page = $this->_getParam('page',1);
$paginator = Zend_Paginator::factory($searchresults);
$paginator->setItemCountPerPage(20);
$paginator->setCurrentPageNumber($page);
$this->view->paginator = $paginator;
Is there a different step I need to do with lucene and zend_paginator? I am really uncertain. The result I get is that for the first page results display properly. But when I hit the second page or third my results are blank. So uncertain what might be wrong as I can't find docs or tutorials in using the two together. Any help would be greatly appreciated.
I think this may work with the iterator adapter:
public function searchAction() {
$index = Zend_Search_Lucene::open('/path/to/lucene');
$results = $index->find($this->_getParam('q'));
$paginator = Zend_Paginator::factory($results);
$paginator->setCurrentPageNumber($this->_getParam('page', 1));
$paginator->setItemCountPerPage(10);
$this->view->results = $paginator;
}
Perhaps the problem you are having is that $paginator doesn't know how many search results there are..
So you may need to do that manually:
$paginator->setDefaultPageRange($results->count());
I want to grab a user's uploads (ie: BBC) and limit the output to 10 per page.
Whilst I can use the following URL:
http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10
The above works okay.
I want to use the query method instead:
The Zend Framework docs:
http://framework.zend.com/manual/en/zend.gdata.youtube.html
State that I can retrieve videos uploaded by a user, but ideally I want to use the query method to limit the results for a pagination.
The query method is on the Zend framework docs (same page as before under the title 'Searching for videos by metadata') and is similar to this:
$yt = new Zend_Gdata_YouTube();
$query = $yt->newVideoQuery();
$query->setTime('today');
$query->setMaxResults(10);
$videoFeed = $yt->getUserUploads( NULL, $query );
print '<ol>';
foreach($videoFeed as $video):
print '<li>' . $video->title . '</li>';
endforeach;
print '</ol>';
The problem is I can't do $query->setUser('bbc').
I tried setAuthor but this returns a totally different result.
Ideally, I want to use the query method to grab the results in a paginated fashion.
How do I use the $query method to set my limits for pagination?
Thanks.
I've decided just to use the user uploads feed as a way of getting pagination to work.
http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10
If there is a way to use the query/search method to do a similar job would be interesting to explore.
I basically solved this in the same way as worchyld with a slight twist:
$username = 'ignite';
$limit = 30; // Youtube will throw an exception if > 50
$offset = 1; // First video is 1 (silly non-programmers!)
$videoFeed = null;
$uploadCount = 0;
try {
$yt = new Zend_Gdata_YouTube();
$yt->setMajorProtocolVersion(2);
$userProfile = $yt->getUserProfile($username);
$uploadCount = $userProfile->getFeedLink('http://gdata.youtube.com/schemas/2007#user.uploads')->countHint;
// The following code is a dirty hack to get pagination with the YouTube API without always starting from the first result
// The following code snippet was copied from Zend_Gdata_YouTube->getUserUploads();
$url = Zend_Gdata_YouTube::USER_URI .'/'. $username .'/'. Zend_Gdata_YouTube::UPLOADS_URI_SUFFIX;
$location = new Zend_Gdata_YouTube_VideoQuery($url);
$location->setStartIndex($offset);
$location->setMaxResults($limit);
$videoFeed = $yt->getVideoFeed($location);
} catch (Exception $e) {
// Exception handling goes here!
return;
}
The Zend YouTube API seems silly as the included getUserUploads method never returns the VideoQuery instance before it actually fetches the feed, and while you can pass a location object as a second parameter, it's an "either-or" situation - it'll only use the username parameter to construct a basic uri or only use the location, where you have to construct the whole thing yourself (as above).
