I'm using Zend_Navigation' reading fron xml.
I want to add to the menu created from it an additional parameter (got it from the request for the first page).
e.g
if the first page is mysite.com/pages/page1?Id=42
then
clicking on the menu would add the "?Id=42" to each link.
Easiest way to do this is by extending the Zend_Controller_Action_Helper_Url class, and adding the query string to the parent::url() result. Than, you need to inject your url helper into the mvc page, by calling Zend_Navigation_Page_Mvc::setUrlHelper($yourUrlHelper).
Example of a query string supported url helper:
class My_Helper_Url extends Zend_Controller_Action_Helper_Url
{
public function url($urlOptions = array(), $name = null, $reset = false, $encode = true)
{
$queryString = $this->getRequest()->getServer('QUERY_STRING');
return parent::url($urlOptions, $name, $reset, $encode) .
($queryString ? '?' . $queryString : '');
}
}

I am doing pagination in REST api developed over slim.
Using below API to get current uri
(string) $request->getUri();
RESULT ::http://localhost/slim/test_app/test/public/api/actions/?page=2
But now for next request i need to replace the page number in current url to (+1) ie 3 here and pass in data returned to user like below
{
"data":[
//data
]
"next": http://localhost/slim/test_app/test/public/api/actions/?page=3
}
What could be the best way to replace the page number ? Do we have any direct api for this,to just replace the attributes ?
I added a function to merge attributes and than bind the query to url as below function
private function merge_querystring($url = null,$query = null,$recursive = false)
{
if($url == null)
return false;
if($query == null)
return $url;
// split the url into it's components
$url_components = parse_url($url);
// if we have the query string but no query on the original url
// just return the URL + query string
if(empty($url_components['query']))
return $url.'?'.ltrim($query,'?');
// turn the url's query string into an array
parse_str($url_components['query'],$original_query_string);
// turn the query string into an array
parse_str(parse_url($query,PHP_URL_QUERY),$merged_query_string);
// merge the query string
if($recursive == true)
$merged_result = array_merge_recursive($original_query_string,$merged_query_string);
else
$merged_result = array_merge($original_query_string,$merged_query_string);
// Find the original query string in the URL and replace it with the new one
return str_replace($url_components['query'],http_build_query($merged_result),$url);
}
and i use below to add query to url
$postQuery["page"]=$currentpage+1;
//print_r($postQuery);
//echo http_build_query($postQuery);
$data["next"]= $this->merge_querystring($request->getUri(),"?".http_build_query($postQuery));
You can replace pagination value by string manipulation. But you can also using what Slim provide.
Slim\Http\Uri class, which implements Psr\Http\Message\UriInterface, has withQuery() method that will replace current query string.
It will return cloned Slim\Http\Uri instance with its query string replaced.
$query = $request->getQueryParams();
$query['page'] = $query['page'] + 1;
$url = $request->getUri();
$nextUrl = $url->withQuery(http_build_query($query));
$data['next'] = (string) $nexUrl;
I don't want to use the default header in my FCE's, but only custom flux fields. In the backend list views my FCE's are shown as "[no title]" because the default header is not filled. This leads to much confusion for editors.
How can I define one of my custom flux fields to be used as title for the FCE in TYPO3 Backend list views etc.?
You can't just use a field from the flexform, because all fields from the FCE are stored in the same field in the database (pi_flexform).
What you can do is to render the content element title with a user function. It is registered with a line like this in the TCA config:
$GLOBALS['TCA']['tt_content']['ctrl']['label_userFunc'] = 'Vendor\\Extkey\\Utility\\ContentElementLabelRenderer->getContentElementTitle';
The user function itself could look like this:
<?php
namespace Vendor\Extkey\Utility;
/**
* This class renders a human readable title for FCEs,
* so one is able to find a content element by its headline.
*/
class ContentElementLabelRenderer implements \TYPO3\CMS\Core\SingletonInterface {
/**
* #var \TYPO3\CMS\Extbase\Service\FlexFormService
* #inject
*/
protected $flexFormService = null;
/**
* Returns the content element title for a given content element
*/
public function getContentElementTitle(&$params) {
if (null === $this->flexFormService) {
$this->flexFormService = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Service\\FlexFormService');
}
if (ctype_digit($params['row']['uid']) && 'fluidcontent_content' === $params['row']['CType']) {
// If this is a FCE, parse the flexform and template name and generate the
// title in a template specific way.
$row = $params['row'];
$additionalRowData = $GLOBALS['TYPO3_DB']->exec_SELECTgetSingleRow('pi_flexform, tx_fed_fcefile', 'tt_content', 'uid = ' . $row['uid']);
$flexFormContent = $this->flexFormService->convertFlexFormContentToArray($additionalRowData['pi_flexform']);
$lastColonPosition = strrpos($additionalRowData['tx_fed_fcefile'], ':');
$contentElementType = (FALSE === $lastColonPosition) ? 'invalidtype' : substr($additionalRowData['tx_fed_fcefile'], $lastColonPosition + 1);
switch ($contentElementType) {
case 'Image.html':
$params['title'] = 'Image: "' . ($flexFormContent['title'] ?: $flexFormContent['subtitle']) . '"';
break;
default:
$params['title'] = 'Unknown content element type';
break;
}
}
else {
// If this is not a FCEm, print out "normal"
// title. Not the real thing, but comes pretty close, hopefully.
$params['title'] = $params['row']['header'] ?: ($params['row']['subheader'] ?: $params['row']['bodytext']);
}
}
}
This produces a maintainance problem though: Every time you add or change a content element, you have to update this file.
I want to handle application feedback regarding, in this case, form validation.
To do this I check for model validation in controller, using
// VALIDATE
if ($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.
In the frontend I have a page with a list and a form filter next to it
that shows all the users of a social network.
I would like to hide the user of the session in that list. How can I
do it?
My first thought is creating a function, addXXXXColumnQuery(), for each
field of the form, and in each one add a line like this:
->andWhere("u.id <> ?", $id)
$id being the ID of the user of the current session. But in that way I
find I'm repeating myself.
What should I do?
First, you need to get the user into the filter. You have two options:
Pass the user_id in as an option when you instantiate the form, inside the action:
public function executeList(sfWebRequest $request)
{
$user_id = $this->getUser()->getUserId();
$filter = new ModelFormFilter(array(), array('user_id' => $user_id));
...
Get the user id from the context inside of the form:
sfContext::getInstance()->getUser()->getUserId();
I prefer the former method because it's cleaner and less WTFy.
Once you have the user id, override doBuildQuery to exclude the current user id inside of your FormFilter:
protected function doBuildQuery(array $values)
{
$query = parent::doBuildQuery($values);
$user_id = $this->getOption('user_id'); //or off the context here
if ($user_id)
{
$query->addWhere('r.user_id != ?', $user_id);
}
return $query;
}
