I appreciate that this may not be possible, but is there a way to make Zend Paginate go to a specific item (record)?
The result I would like would allow me to seek a specific record in a tabled list of results, and display the appropriate page (within all available pages) combined with a name anchor tag to display the specific record.
To clarify: If I had the results as a Zend_Db_Table_Rowset_Abstract I would use the seek() method in a similar fashion to $rowset->seek(8); Although I don't believe the result returned by the DbSelect adapter is a SeekableIterator?
The code within my Mapper (using the Table Data Gateway pattern):
public function paginate($where = array(), $order = null)
{
$select = $this->getDbTable()->select()->from($this->getTableName(), $this->getTableFields());
foreach ($where as $key => $value) {
$select->where($key, $value);
}
$select->order($order);
$adapter = new Zend_Paginator_Adapter_DbSelect($select);
$paginator = new Zend_Paginator($adapter);
return $paginator;
}
Within my controller:
$cache_id = sha1('list');
$mapper = new Application_Model_Galleries_Mapper();
if(!($data = Zend_Registry::get('cache')->load($cache_id))) {
$data = $mapper->paginate(array(), $sort);
Zend_Registry::get('cache')->save($data, $cache_id, array('list'), 7200);
}
$data->setCurrentPageNumber($this->_getParam('page'));
$data->setItemCountPerPage(30);
$this->view->paginator = $data;
To return a Zend_Paginator with a seekable iterator (Zend_Db_Table_Rowset) use the Zend_Paginator_Adapter_DbTableSelect() as it returns a rowset object, as opposed to Zend_Paginator_Adaoter_DbSelect() which returns an array().

How would I write an Zend DB query to select all from the column ID?
So far I have tried:
public function getLatestUserID()
{
$ids = $this->select()
->where('id = ?');
return $ids;
}
But to no avail.
You just want the id column,
You failed to call an execute command.
try:
//assuming you are using a DbTable model
public function getLatestUserID()
{
$ids = $this->fetchAll('id');
return $ids;
}
I would do it like this, because I use the select() object for everything:
public function getLatestUserID()
{
$select = $this->select();
//I'm not sure if $this will work in this contex but you can out the table name
$select->from(array($this), array('id'));
$ids = $this->fetchAll($select);
return $ids;
}
The first two examples should return just the id column of the table, now if you actually want to query for a specific id:
public function getLatestUserID($id)
{
$select = $this->select();
$select->where('id = ?', $id);
//fetchAll() would still work here if we wanted multiple rows returned
//but fetchRow() for one row and fetchRowset() for multiple rows are probably
//more specific for this purpose.
$ids = $this->fetchRow($select);
return $ids;
}
make sure your class containing getLatestUserID does extend Zend_Db_Table_Abstract also :
$ids = $this->select()->where('id = ?'); can't work because where('id = ?'); expects an id value like where('id = ?', $id);
if what you want is the latest inserted row's Id use :
$lastInsertId = $this->getAdapter()->lastInsertId();
(however if you are using an oracle database this will not work and you should use $lastInsertId = $this->getAdapter()->lastSequenceId('USER_TABLE_SEQUENCE'); )
I have a number of FilteringSelect elements within my Zend Framework application that are working fine but they are based on simple queries.
I now need to create a FilteringSelect that will allow me to select the id of one table while displaying the text of field in a related table, i.e. I have two tables groomservices and groomprocedures which are related (i.e. groomprocedures.groomProceduresID has many groomservices.procedure).
The form I'm trying to create is for an appointments table which has many groomservices.groomServicesID values. I want the user to be able to see the name of the procedure while saving the value of the groomservices.groomServicesID using the FilteringSelect.
So far I've not been able to do this in that my FilteringSelect displays nothing, I'm sure this can be done just that the fault is with my inexperience with Zend,Doctrine and Dojo
I'm not sure if my problem is with my autocomplete action(including the query) or with the FilteringSelect element.
Can anyone spot where I've gone wrong in the code sections below, I need to get this working.
My autocomplete action within my controller
public function gserviceAction()
{
// disable layout and view rendering
$this->_helper->layout->disableLayout();
$this->getHelper('viewRenderer')->setNoRender(true);
// get a list of all grooming services IDs and related procedures
$qry= Doctrine_Query::create()
->select('g.groomServicesID,p.groomProcedure')
->from('PetManager_Model_Groomservices g')
->leftJoin('g.PetManager_Model_Groomprocedures p');
$result=$qry->fetchArray();
//generate and return JSON string
$data = new Zend_Dojo_Data('g.groomServicesID',$result);
echo $data->toJson();
}
My FilteringSelect element code
// Create a autocomplete select input for the service
$gservice = new Zend_Dojo_Form_Element_FilteringSelect('gapmtService');
$gservice->setLabel('Proceedure');
$gservice->setOptions(array(
'autocomplete' => true,
'storeID' => 'gserviceStore',
'storeType' => 'dojo.data.ItemFileReadStore',
'storeParams' => array('url' => "/groomappointments/appointment/gservice"),
'dijitParams' => array('searchAttr' => 'groomProcedure')))
->setRequired(true)
->addValidator('NotEmpty', true)
->addFilter('HTMLEntities')
->addFilter('StringToLower')
->addFilter('StringTrim');
Many thanks in advance,
Graham
P.S. orgot to mention I tried the following query in mysql and I gave me what I'm looking for I believe the Doctine query evaluates to the same.
select groomservices.groomservicesID,groomprocedures.groomprocedure from groomprocedures left join groomservices on groomprocedures.groomproceduresID =groomservices.groomProcedure
But I'm not sure if I formatted the query correctly in Doctrine.
EDIT in relation to the flammon's comments
Ok I've set the code to the following but I'm still not getting anything to display.
public function gserviceAction()
{
$ajaxContext = $this->_helper->getHelper('AjaxContext');
$ajaxContext->addActionContexts(array(
'gservice' => 'json'
));
// get a list of all grooming services IDs and related procedures
$qry= Doctrine_Query::create()
->select('g.groomServicesID AS id,p.groomprocedure AS name')
->from('PetManager_Model_Groomservices g')
->leftJoin('g.PetManager_Model_Groomprocedures p');
$this->view->model = (object) array();
$this->view->model->identifier = 'id';
$this->view->model->label = 'name';
$this->view->model->items = array();
$tableRows = $this->dbTable->fetchAll($qry);
foreach ($tableRows as $row) {
$this->view->model->items[] = $row->toArray();
}
}
I'm sure the fault lies with me.
It looks like there's a problem with the data that you're putting in the ItemFileReadStore.
Here are a few pointers.
Consider extending Zend_Rest_Controller for your services. It'll be easier to manage your contexts and your views. You'll be able to do something like this:
public function init()
{
$ajaxContext = $this->_helper->getHelper('AjaxContext');
$ajaxContext->addActionContexts(array(
'gservice' => 'json'
));
}
And it will eliminate the need for the following in each of you service actions.
// disable layout and view rendering
$this->_helper->layout->disableLayout();
$this->getHelper('viewRenderer')->setNoRender(true);
You'll need to either pass the format parameter or use the following plugin to help with the context switch. Passing the format parameter is simpler but it pollutes the url with ?format=json. Here's the Zend documentation on AjaxContext.
Here's a plugin that you can use if you don't want to pass the format parameter.
class Application_Plugin_AcceptHandler extends Zend_Controller_Plugin_Abstract
{
public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
if (!$request instanceof Zend_Controller_Request_Http) {
return;
}
$header = $request->getHeader('Accept');
switch (true) {
case (strstr($header, 'application/json')):
Zend_Registry::get('logger')->log('Setting format to json', Zend_Log::INFO);
$request->setParam('format', 'json');
break;
case (strstr($header, 'application/xml')
&& (!strstr($header, 'html'))):
Zend_Registry::get('logger')->log('Setting format to xml', Zend_Log::INFO);
$request->setParam('format', 'xml');
break;
default:
Zend_Registry::get('logger')->log('Setting format to html', Zend_Log::INFO);
break;
}
}
}
In your controller, instead of echoing the data, create view variables that dojo expects. See this document for the format.
$this->view->model = (object) array();
$this->view->model->identifier = 'id';
$this->view->model->label = 'name';
$this->view->model->items = array();
In your controller, fetch your table rows:
$tableRows = $this->dbTable->fetchAll($select);
or, if you've put model code in a function, it might look more like:
$tableRows = $this->dbTable->fetchGroomProcedures();
Put your row data in the model->items[] array:
foreach ($tableRows as $row) {
$this->view->model->items[] = $row->toArray();
}
Create a view, view/scripts/appointment/gservice.json.phtml and in it put
Zend_Json::encode($this->model)
Use Firebug to see what is returned from your service.
In Zend Form, if two elements have the same order, then Zend will totally ignores the second element (instead of displaying it under the first). Take the following code as an example. Notice that the City and Zip Code elements have the same order of 4
$address = new Zend_Form_Element_Textarea('address');
$address->setLabel('Address')
->setAttrib('cols', 20)
->setAttrib('rows', 2)
->setOrder(3)
;
$city = new Zend_Form_Element_Text('city');
$city->setLabel('City')
->setOrder(4)
;
$postal = new Zend_Form_Element_Text('postal');
$postal->setLabel('Zip Code')
->setOrder(4);
When this form renders, the Zip Code element is nowhere to be found.
If I want to set elements like a buttons dynamically, but tell it to render at the end of the form, how would I do this and not run into the problem of having two elements with the same order?
public function addSubmitButton($label = "Submit", $order = null)
{
$form_name = $this->getName();
// Convert Label to a lowercase no spaces handle
$handle = strtolower(str_replace(" ","_",$label));
$submit = new Zend_Form_Element_Submit($handle);
$submit->setLabel($label)
->setAttrib('id', $form_name . "_" . $handle)
;
///////// Set the button order to be at the end of the form /////////
$submit->setOrder(??????);
$this->addElement($submit);
}
If you really need to use the setOrder() method, I'd work with order numbers 10, 20, 30, 40, ... This way it will be easy to add elements in between already set Elements.
Furthermore, in order to avoid using order-numbers twice, you could use an array, where you store all the numbers from 1 to X. Whenever you set an order number, you set it via a method called getOrderNumberFromArray() which returns the next higher or lower order number still available in the array and unsets this array element.
Alternatively, and maybe even better, you could do getOrder() on the element you want to have before the new element, then increment this order number by X and then loop through the existing form elements and check that the order number doesn't exist yet.
Or you could just use getOrder() on the Element you want to show before and after the new element and make sure you don't use the same order numbers for the new element.
Sorry to be late to the question. What I did was extend Zend_Form and override the _sort() method as follows:
/**
* Sort items according to their order
*
* #return void
*/
protected function _sort()
{
if ($this->_orderUpdated) {
$items = array();
$index = 0;
foreach ($this->_order as $key => $order) {
if (null === $order) {
if (null === ($order = $this->{$key}->getOrder())) {
while (array_search($index, $this->_order, true)) {
++$index;
}
$items[$index][]= $key;
++$index;
} else {
$items[$order][]= $key;
}
} else {
$items[$order][]= $key;
}
}
ksort($items);
$index = 0;
foreach($items as $i=>$item){
foreach($item as $subItem){
$newItems[$index++]=$subItem;
}
}
$items = array_flip($newItems);
asort($items);
$this->_order = $items;
$this->_orderUpdated = false;
}
}
This differs from the original sort method by putting the items in an array based off of their index and then doing a depth-first traversal to flatten the array.
Try this code:
$elements = array();
$elements[] = new Zend_Form_Element_Textarea('address');
......
$elements[] = new Zend_Form_Element_Text('city');
.......
$elements[] = new Zend_Form_Element_Submit($handle);
.....
$this->addElements($elements);
All you need to do is add them in the order you want them to show
what i would do is - use a temp array for that - in that keep the element names in desired order (don't mind the keys). Then use foreach like this:
foreach(array_values($tempArray) as $order => $name) {
$form->$name->setOrder($order+1);
}
Note the array_values - it will return the values as numbered array ;) Not sure if setOrder(0) works - that's why there is +1
I get a really anoying error when I try to edit an entry from a table, in tutorial they always use getTable()->find(), but I need to verify that the person logged in is the owner of that entry here what I did:
In the action:
public function executeEdit(sfWebRequest $request)
{
$id = $request->getParameter('id');
$userid = $this->getUser()->getGuardUser()->getId();
$ad = Doctrine_Core::getTable('BambinbazarArticles')->getMyAd($id, $userid);
$this->forward404Unless($ad, sprintf('Object bambinbazar_articles does not exist (%s).', $request->getParameter('id')));
$this->form = new BambinbazarArticlesForm($ad);
}
In the model:
public function getMyAd($id, $userid)
{
$q = $this->createQuery('c')
->where('c.id = ? ', $id)
->addWhere('c.userid = ? ', $userid);
return $q->execute();
}
I tried it with and without the ->execute(), did doctrine clean, cleared cache, rebuilded model,
Always get the same error 'The "%s" form only accepts a "%s" object.
If I use the Doctrine_Core::getTable('BambinbazarArticles')->find() it work, but of course, i need more than that..
I am becoming crazy over this.
execute() can return multiple rows; effectively you're getting a recordset back, rather than the individual object that your form is expecting. Try fetching a single object, using, e.g.:
return $q->execute()->getFirst();
or
return $q->fetchOne();
Its probably because your query is returning a Doctrine_Collection, not the actual Doctrine_Record youre expecting. Instead of execute use fetchOne.
public function getMyAd($id, $userid)
{
$q = $this->createQuery('c')
->where('c.id = ? ', $id)
->addWhere('c.userid = ? ', $userid)
->limit(1);
return $q->fetchOne();
}
I want to cache my results from Zend_Lucene_Search using Zend_Paginator::setCache()
I get the following error:
Warning: fseek() expects parameter 1 to be resource, integer given
Here is the portion of code:
// Load index
$index = Zend_Search_Lucene::open(APPLICATION_PATH . '/indexes');
// Paginate
$paginator = Zend_Paginator::factory($index->find($query));
$paginator->setCache($this->_cache);
$paginator->setItemCountPerPage($items);
$paginator->setCurrentPageNumber($page);
// Send to view
$this->view->hits = $paginator;
In other areas of the site where I use the same technique to cache paginated results that are not from Zend_Lucene_Search, this works fine.
I read somewhere that storing results in a session or cache destroys the lucene document and that you have to convert the QueryHit objects to stdClass objects, but how? Does this work?
Ok solved it, I was overthinking it
$hits = $index->find($query);
$this->view->totalHits = count($hits);
// Convert to stdClass to allow caching
foreach ($hits as $i => $hit) {
$resultsArray[$i] = new stdClass();
$doc = $hit->getDocument();
foreach($doc->getFieldNames() as $field){
$resultsArray[$i]->{$field} = $hit->{$field};
}
}
// Paginate
$paginator = Zend_Paginator::factory($resultsArray);
$paginator->setCache($this->_cache);
$paginator->setItemCountPerPage($items);
$paginator->setCurrentPageNumber($page);
// Send to view
$this->view->hits = $paginator;
