I have written code for accessing the array from the controller to view. but i am not able to access data on view.
codes are given below.
<?php
public function Student(){
$exam_no_students = array();
$exam_centers['no_of_centers']= $this->DB1->count_centers();
$exam_centers1= $this->DB1->count_centers();
foreach ($exam_centers1 as $center_code => $center_details){
$center_code = array('center_id' =>$center_details->center_id);
$center_table='exam_center';
$center_full_details =$this->DB1->getArrayWhereResult($center_table,$center_code);
foreach ($center_full_details as $full => $full_de) {
$fullstudent = array('center_f_id' =>$full_de->center_id,
'center_f_name' =>$full_de->exam_center,
'center_f_addres' =>$full_de->exam_center_address ,
'center_f_city' =>$full_de->village ,
'center_f_count' =>$center_details->count);
}
array_push($exam_no_students, $fullstudent);
}
}
}
$abcd['assignment']=$exam_no_students;
$this->load->view('dissa');
$this->load->view('dissa',$abcd);
I am not able to access variable assignment at the view.
Message: Trying to get property of non-object please give me suggestion.
Thanks.

Model:
public function fetch_emp()
{
$this->db->select('emp_id');
$this->db->from('emp');
$res=$this->db->get();
foreach($res->result() as $row)
{
$id=$row->emp_id;
$this->db->select('emp_name');
$this->db->from('employee_master');
$this->db->where('emp_id',$id);
$res=$this->db->get();
return $res->result();
}
}
Controller:
public function employee()
{
$result=$this->emp_model->fetch_emp();
if($result!=false)
$res['cmp_name']=$result;
else
$res['cmp_name']='NA';
}
$this->loadViews("emp/emp_views", $this->global, $res , NULL);
}
View:
<?php print_r($cmp_name);?>
Once I fetch the id from db I got all the id not problem at all, but when I used in foreach loop to search the id and get their names from another db It display only the 1st id name... For eg:If there are 5 id, but when I search the id to get the name from another db it shows the 1st id name only.What's the problem I don't know pls help me.
You could get it done (getting names list) by directly using join() method like this :
public function fetch_emp()
{
$this->db->select('emp_name');
$this->db->from('emp');
$this->db->join('employee_master', 'employee_master.emp_id = emp.emp_id');
$res=$this->db->get();
return $res->result();
}
I have a database table called input_types with a various input types:
[id] [input_type_Name]
1 text
2 radio
3 checkbox
4 select
... ...
I want to retrieve the names from the table and put them in an array so that I can then use form_dropdown to show them to the user in a dropdown.
The problem with how I'm doing it now is that I create optiongroups.
How I do it now:
Model
function get_inputTypes() {
$this->db->select('input_type_name');
$query = $this->db->get('input_types');
if($query->num_rows() > 0) {
return $query->result_array();
}
else {
return false;
}
}
Controller
$results = $this->survey_model->get_inputTypes();
$data['inputTypes'] = $results;
View
<label for="inputType">Input type:</label>
<?php echo form_dropdown('inputType', $inputTypes); ?>
This however doesn't create the desired effect. My dropdown gets populated, but because I have a multidimensional array the dropdown has optgroups.
I just want to have my selected data in a simple array. Why is this so freaking hard in CodeIgniter and php in general.
C# is much easier :/
Solution
The solution is very simple, use a foreach to loop through the multidimensional array in the model:
foreach($query->result() as $input_type) {
$data[] = $input_type->input_type_name;
}
return $data;
What do you mean by "This however doesn't create the desired effect" ?
Make sure you pass the $data to your view:
$this->load->view('viewname', $data);
The solution is very simple, use a foreach to loop through the multidimensional array in the model:
foreach($query->result() as $input_type) {
$data[] = $input_type->input_type_name;
}
return $data;
I want to handle application feedback regarding, in this case, form validation.
To do this I check for model validation in controller, using
// VALIDATE
if ($this->Event->validates($this->data))
{
// SAVE
$this->Event->create();
if ($this->Event->saveAll($this->data, array('validate' => false)))
{
$this->Session->setFlash('Evenimentul a fost salvat!', 'flash_admin_success');
$this->redirect(array('action' => 'index', 'admin' => true));
} else {
$this->Session->setFlash('Evenimentul nu a putut fi salvat. Va rugam sa incercati din nou!', 'flash_admin_error');
}
////////
$errors = 'O EROARE';
$this->set(compact('errors'));
}
else
{
// GET ERRORS to display it nicely :)
$errors = $this->Event->invalidFields();
$flash = '';
foreach($errors as $error)
{
$flash .= $error."<br />";
}
$this->Session->setFlash($flash, 'flash_admin_error');
}
I know that there is a way to get rid of form field errors using 'error' => false, but i want to set this for the entire application, thus for all fields in all forms.
It has to be there a way of setting that fot the object itself, and I would be gratefull if someone would tell me.
Thaks a lot!
Edit: This doesn't really disable error output, but will hide the error: go to webroot/css/cake.generic.css add display:none to selector div.error-message. That's the simplest way to achieve what you want that I can think of.
Though it may seem like a bit of an extreme approach to override a single property, you can achieve this by extend the core FormHelper. This will allow you to make Anh Pham's original suggestion the default for all FormHelper instances:
// app/views/helpers/app_form.php
App::import('Helper', 'Time');
class AppFormHelper extends FormHelper {
public $_inputDefaults = array('error' => false);
}
Now to use this as-is in CakePHP 1.3, you would have to use "AppForm" throughout your application to refer to this helper from now on (ie. $this->AppForm->input()). CakePHP 2.0 introduces helper aliasing to overcome this, but for now one has to resort to a bit of trickery to continue using "Form" instead. One blog post I found shows how to backport the functionality and another manages allow the helper to do it itself. I personally use the following without any problems:
// app/views/app.php
class AppView extends View {
function &_loadHelpers(&$loaded, $helpers, $parent = null) {
$return = parent::_loadHelpers($loaded, $helpers, $parent);
# rename App helpers (ie. AppHtml -> Html)
foreach ($return as $helperName => $helper) {
if (substr($helperName, 0, 3) === 'App') {
$newHelperName = substr($helperName, 3);
$return[$newHelperName] = $return[$helperName];
}
}
# done
return $return;
}
}
To use the new created classes above, just add the following to your AppController:
// app/app_controller.php
class AppController extends Controller {
public $helpers = array(/*...*/, 'AppForm');
public $view = array('App');
}
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();
}
