I have a CodeIgniter application, but one of my controllers must call a data processing function that I have also written myself. The only problem is I can't seem to figure out how to do this. Looking through the user guide it seems that I should put my function inside the class declaration, and prefix it with an underscore (_) so that it cannot be called via the url. However, this is not working. Here's an example of what I mean:
<?php
class Listing extends Controller
{
function index()
{
$data = "hello";
$outputdata['string'] = _dprocess($data);
$this->load->view('view',$outputdata);
}
function _dprocess($d)
{
$output = "prefix - ".$d." - suffix";
return $output
}
}
?>
The page keeps telling me I have a call to an undefined function _dprocess()
How do I call my own functions?
Thanks!
Mala
Edit:
I've gotten it to work by placing the function outside of the class declaration. Is this the correct way of doing it?
This line is creating problem for you:
$outputdata['string'] = _dprocess($data);
Replace with:
$outputdata['string'] = $this->_dprocess($data);

I'm probably missing something really obvious here, but is there a function in CakePHP (I'm on 3.8) that returns the name of a controller without creating an instance of the class?
An instanced controller can call this function:
echo $this->name;
But what I'd like to be able to do, is avoid typing the controller name as a string in, say, an HTML->link(); ie a static call something like:
echo $this->Html->link(
'Dashboard',
['controller' => DashboardsController::name, 'action' => 'index']
);
The reason is that I'm refactoring a couple of controllers and am having to find and replace all of those strings by hand. I come from a .Net background and CakePHP is pretty new to me, so if there's a better (more cakeish) way to carry out the refactoring than the question I'm asking, then I'd be really glad to hear it.
Nothing in the documents is leaping out at me, but I've a feeling there should be a simple answer.
The namespace of a class can be retrieved using ::class property. Checkout the following example:
DashboardsController::class // Cake/Controllers/DashboardController
The name without the namespace can be retrieved with ReflectionClass:
$function = new \ReflectionClass(DashboardsController::class);
var_dump($function->inNamespace());
var_dump($function->getShortName());
Shortname can be used to get the class without namespace:
namespace App;
class Test {
public static function name(){
$function = new \ReflectionClass(self::class);
return $function->getShortName();
}
}
var_dump(Test::name());
Checkout the docs: https://www.php.net/manual/en/language.oop5.constants.php#example-186

I'm trying to load a listener but symfony keeps throwing this error:
ClassNotFoundException in appDevDebugProjectContainer.php line 1783:
Attempted to load class "CommandeListener" from namespace "Louvre\ReversationBundle\Services\Listeners".
Did you forget a "use" statement for another namespace?
My class is properly writen (i guess):
<?php
namespace Louvre\ReservationBundle\Services\Listeners;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpKernel\Event\FilterResponseEvent;
class CommandeListener {
public function checkCommand(FilterResponseEvent $event){
if (!$event->isMasterRequest() && $event->getRequest()->get('_route') == "louvre_reservation_step1") {
return;
}
$url = $this->router->generate("louvre_reservation_step1");
$response = new RedirectResponse($url);
$event->setResponse($response);
}
}
Its path is
src/Louvre/ReservationBundle/Services/Listeners/CommandeListener.php
and here is the yaml service
louvre_reservation.commande.listener:
class: Louvre\ReversationBundle\Services\Listeners\CommandeListener
tags:
- { name: kernel.event_listener, event: kernel.request, method: checkCommande }
I have other services which work perfectly.
they are declared the same way.
I googled the problem but could not find an answer.
Does anyone already faced this problem?
Thanks in advance
It looks like you made a typo in your class include. You wrote "Reversation" instead of "Reservation" which make your code looks into the "Reversation" folder which does not exists.
I made a file in library/My/Utils/Utils.php. The content of the file is :
class My_Utils_Utils{
public function test(){
$this->_redirect('login');
}
}
This class is called from a layout; the problem is with the _redirect(); I get this error : The page isn't redirecting properly. My question is how call the _redirect() function from a class made by you in ZEND framework 1 .
Thanks in advance.
Use redirect() instead of _redirect(). Usage is:
$this->redirect(<action>, <controller>, <module>, <param>);
In your case $this->redirect('login'); should do the trick.
You can use the redirector action-helper, which you can get statically from the HelperBroker using:
// get the helper
$redirectHelper = Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
// call methods on the helper
$redirect->gotoUrl('/some/url');
It should be noted, however, that the layout is considered part of the view layer. Typically, any checks that result in a redirect should probably take place earlier in the request dispatch-cycle, typically in a controller or in a front-controller plugin.
The _redirect function is provided by the class Zend_Controller_Action. You can fix this in two ways :
Extend Zend_Controller_Action and use _redirect
class My_Utils_Utils extends Zend_Controller_Action {
public function test(){
$this->_redirect('login');
}
}
in layout:
$request = Zend_Controller_Front::getInstance()->getRequest();
$response = Zend_Controller_Front::getInstance()->getResponse()
$util = new My_Utils_Utils($request, $response); // The constructor for Zend_Controller_Action required request and response params.
$util->test();
Use gotoUrl() function Zend_Controller_Action_Helper_Redirector::gotoUrl()
$redirector = new Zend_Controller_Action_Helper_Redirector();
$redirector->gotoUrl('login');
//in layout :
$util = new My_Utils_Utils();
$util->test();
I have a Red5 service function that receives a single string as a parameter, and another function that takes no parameters, like the code below:
public class AService
{
private String someName;
public void setName(String aName)
{
someName = aName;
}
.
.
public String makeMessage()
{
return("Hello, "+someName);
}
.
.
other functions
}
I also have an ActionScript function that calls the service function, using the dynamic parameter:
public class Connector
{
private var netConn: NetConnection;
public function invokeCall(theFunc:String,...theParams): void
{
var resp:Responder = new Responder(checkResult);
netConn.call(theFunc,resp,theParams);
}
.
.
}
I am aware that the "...theParams" is actually an array of parameter objects. I also know that the NetConnector class' call() method uses that parameter object array. Unfortunately, when I do an invokeCall() on my service's makeMessage() method (without putting in a parameter) like so:
invokeCall("AService.makeMethod");
I get a function nonexistent message from Red5. The only way I can make it work is to create two invoke methods, one with parameters and one without, and call that function without parameters.
Furthermore, calling my setName() function, like so:
invokeCallwithPrams("AService.setName","factor3");
doesn't seem to work unless I change the signature of my service function:
public class AService
{
private String someName;
public void setName(String[] aName)
{
someName = aName[0];
}
.
.
public String makeMessage()
{
return("Hello, "+someName);
}
.
.
other functions
}
which I don't mind (even though the Red5 documentation indicates that I shouldn't have to treat the parameter as an array), except that when I pass the string "factor3" into the NetConnection class' call() method, somehow it becomes "[factor3]" in setName()!
Obviously, something is screwy here, but I haven't been able to figure it out.
I am using Red5 Version 1.0.1 and my Actionscript is Version 3.
Can anyone explain to me what is going on and (more importantly) how to fix this???
If so, please advise...
UPDATE: The weirdness continues
I did a test in which I changed the parameter of the function I used to set up and invoke the NetConnection class' call() method. Instead of passing it a "...theParams", I changed it to theParams:String, like so:
public function invokeCall(theFunc:String,theParams:String): void
{
var resp:Responder = new Responder(checkResult);
netConn.call(theFunc,resp,theParams);
}
Interestingly, the brackets that appear in my service method setName() go away!
Whatever this problem is, it has something to do with the dynamic parameters in Actionscript. I suspect that I have found a bug in Actionscript 3 that does not allow it to properly handle dynamic parameters that are passed to a method from another method.
Has anyone else seen this problem? Is there any solution? The dynamic parameters are supposed to allow anyone to add parameters as necessary and make them any object that is necessary. Unfortunately, it doesn't look like you can use dynamic parameters passed from another method without them being screwed up.
This looks like a serious bug in Actionscript. Am I correct?
Someone please advise...
I found the solution. It is not a bug in Actionscript, it is a bit of strangeness in the language.
The basic information about the solution can be found here:
AS3 variable length argument expand to call another function with var length args
Based on what is there, I needed to do the following in the method I am using for invokeCallwithParams:
.
.
var conn:Connector = new Connector();
private function invokeCaller(fName:String,...cParams)
{
cParams.unshift(fName);
conn.invokeCall.apply(conn,cParams);
}
This eliminates the unnecessary brackets passed into my setName() service function, meaning that I can pass dynamic, variable length parameters from one method to another...
I'm using Zend Framework 1 with the Bisna library to integrate Doctrine 2. I generated my Entities from my database model with the Doctrine 2 CLI. This is all working fine, except for the setter methods for associated records. The argument they accept must be of a specific namespace (\Category here).
class Article
{
public function setCategory(\Category $category = null) {
$this->category = $category;
return $this;
}
}
However, when I do this:
$article = $this->em->getRepository('\Application\Entity\Article')->find(1);
$category = new \Application\Entity\Category();
$category->SetName('New Category');
$article->setCategory($category);
I get the following fatal error: Argument 1 passed to Application\Entity\CategoryField::setCategory() must be an instance of Category, instance of Application\Entity\Category given.
When I change the setter method to accept \Application\Entity\Category objects, it's working of course. Should I do this for every generated method, or are there other options? This is the first time I'm using namespaces, so it might be something simple.
You can always add this to the top of your class file: use \Application\Entity\Category; and then simply reference it later like so: public function setCategory(Category $category = null)
Check out: http://php.net/manual/en/language.namespaces.importing.php for more info about use
Otherwise you would have to reference the full namespace otherwise your application does not know that \Category is a reference to \Application\Entity\Category
