Hi im new with zend and this question probably be ridiculous but i have a trouble getting values from the following:
$country = new Zend_Form_Element_Select('_country');
$country->setLabel('Country:');
$country->addMultiOptions(array('0'=>'United States',
'1'=>'Bolivia',
'2'=>'Argentina',
'3'=>'Afganistan'));
$country->setRequired(true);
But im not sure how i can get the values, i tried like this on my controller:
if ($this->_request->getPost()) {
$formData = $this->_request->getPost();
$form = new App_Form_CustomerForm();
if ($form->isValid($formData)) {
$customer = $customerDao->getById($id);
$customer->setCountry($formData[0]['_country']);
$customerDao->save($customer);
$this->_helper->redirector('index');
return;
Im thinking of use only html code to do this select but i want to know how get these values .
you can get the values from zend element using the getValue() method
Populating and Retrieving Values
The code would be
if ($form->isValid($formData)) {
$customer = $customerDao->getById($id);
$customer->setCountry($form->getValue('_country'));
$customerDao->save($customer);
$this->_helper->redirector('index');
return;
}

I am very new to zend framework. I want to declare a form object inside an if condition. but I don't know is it possible or not ?. I write the below code:
public function editAction()
{
$modelUsers = new Model_Users();
$userId = $this->_getParam('userId');
if ($userId) {
$populateData = array();
$user = $modelUsers->fetch($userId);
// print_r($user); exit();
if ($user instanceof Model_User) {
$populateData = $user->toArray();
$form = $this->_geteditForm($user->email);
}
$form->populate($populateData);
}
$request = $this->getRequest();
if ($request->isPost()) {
Please let me know I am going to the write path or not.
Thanks in advance
It's OK, but (assuming that it's some kind of a crud) it's better to redirect back to list or throw exception if the ID is missing. Than you don't need to close the whole form in condition. i.e:
if (!$userId = $this->_getParam('userId')) {
throw new Exception('Missing userId');
//or
$this->_helper->redirector('index');
}
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().

I'm working on a zend framework project and I needed the user to select school and then it goes to the next form then select the grade.
Eg User select ABC High School and then select "Grade 8"
Both School and Grade dropdown menu is soft coded fetching the data from the database.
My problem is that when the user selected a school and then on the next grade form if they don't select any values and click onto "submit" it return a validation error "Value is required and can't be empty" which is correct but the dropdown menu then goes empty.
I wanted to know how to repopulate the values back to the grade dropdown menu if the form doesn't validate.
Thanks so much
Here is my code
Here is the function i generate the grade values (Fetching from the database)
public function processSchoolSelectionAction()
{
$form = $this->getSchoolSelectionForm();
if ($form->isValid($_POST))
{
// getting the values
$schoolId = $form->getValue('school');
$schoolYear = new Application_Model_DbTable_SchoolYear();
$schoolYearValues = $schoolYear->getYearValues($schoolId);
array_unshift($schoolYearValues, array ('key' =>'' , 'value' =>'Please Specify'));
$form = $this->getYearSelectionForm();
$form->year->addMultiOptions($schoolYearValues);
$form->schoolId->setValue($schoolId);
$this->view->form = $form;
}
else
{
$data = $form->getValues();
$form->populate($data);
$this->view->form = $form;
}
}
Code processing the year selection form
public function processYearSelectionAction()
{
$form = $this->getYearSelectionForm();
if ($form->isValid($_POST))
{
// getting the values
$schoolId = $form->getValue('schoolId');
$yearId = $form->getValue('year');
$textbookList = new Application_Model_DbTable_TextbookList();
if ($textbookList->checkTextbookExist($schoolId, $yearId))
{ // check if textbookExist
}
else
{
$this->view->message = "Sorry, But the list you requested is currently not available for ordering online.";
}
}
else
{
$data = $form->getValues();
$form->populate($data);
$this->view->form = $form;
}
}
School selection form
<?php
class Application_Form_SchoolSelection extends ZendX_JQuery_Form
{
public function init()
{
$this->setName('schoolSelection');
$school = new Application_Model_DbTable_School;
$schoolValues = $school->getSchoolValues();
array_unshift($schoolValues, array ('key' =>'' , 'value' =>'Please Specify'));
$schoolElement = new Zend_Form_Element_Select('school');
$schoolElement->addMultiOptions($schoolValues);
$schoolElement->setLabel('School');
$schoolElement->setRequired(true);
$schoolElement->setRegisterInArrayValidator(false);
$submitElement = new Zend_Form_Element_Submit('submit');
$submitElement->setLabel("Next");
$this->addElements(array(
$schoolElement,
$submitElement
));
}
}
?>
Grade (Year) selection form
<?php
class Application_Form_YearSelection extends ZendX_JQuery_Form
{
public function init()
{
$this->setName('yearSelection');
$yearElement = new Zend_Form_Element_Select('year');
$yearElement->setLabel('Year');
$yearElement->setRequired(true);
$yearElement->setRegisterInArrayValidator(false);
$schoolIdElement = new Zend_Form_Element_Hidden('schoolId');
$submitElement = new Zend_Form_Element_Submit('submit');
$submitElement->setLabel("Next");
$this->addElements(array(
$yearElement,
$schoolIdElement,
$submitElement
));
}
}
?>
This is how I done that:
In Controller when form is creating, pass data from request:
$some_selected_data = $this->_getParam('param_from_request'); // you need to validate this
$form = new Application_Form_SchoolSelection( array('some_data' => $some_selected_data) );
Then, in Form Class get that value like this:
$data = $this->getAttrib('some_data'); // the key value of array above
and just ask
if($data) {
// get value from DB and
//SET VALUE TO Zend_Form_Element
}
Obviously, you need to repopulate the options of your Select field.
In your processYearSelectionAction, on the validation failure part just grab the schoolId you stored in the hidden field and use it the same way as you did in your processSchoolSelectionAction to populate your field options.
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.
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();
}
