in symfony i can use the setter injection for services via call option (https://symfony.com/doc/current/service_container/calls.html)
The example from the symfony documentation:
class MessageGenerator
{
private $logger;
public function setLogger(LoggerInterface $logger)
{
$this->logger = $logger;
}
// ...
}
service.yml
services:
App\Service\MessageGenerator:
# ...
calls:
- method: setLogger
arguments:
- '#logger'
I need this behaviour for my zend project. i want to inject a InputFilter into my FormFieldSet.
I didn't find anything about this in the zend documentation. Can i use something like this or exist a better solution for my problem in zend?
Based on this question and your previous question about Forms, Fieldsets and InputFilters, I'm thinking you want to achieve something similar to the following use case.
Use case
You have a
Location Entity
Address Entity
Location has a OneToOne to an Address (required, uni-directional)
Requirements
To manage the Location, you'll need:
LocationForm (-Factory)
LocationFormInputFilter (-Factory)
LocationFieldset (-Factory)
LocationFieldsetInputFilter (-Factory)
AddressFieldset (-Factory)
AddressFieldsetInputFilter (-Factory)
Configuration
To configure this in ZF3, you'll have to do add the following
'form_elements' => [
'factories' => [
AddressFieldset::class => AddressFieldsetFactory::class,
LocationForm::class => LocationFormFactory::class,
LocationFieldset::class => LocationFieldsetFactory::class,
],
],
'input_filters' => [
'factories' => [
AddressFieldsetInputFilter::class => AddressFieldsetInputFilterFactory::class,
LocationFormInputFilter::class => LocationFormInputFilterFactory::class,
LocationFieldsetInputFilter::class => LocationFieldsetInputFilterFactory::class,
],
],
Forms & Fieldsets
In the LocationForm, add your LocationFieldset and what else your Form needs, such as CSRF and submit button.
class LocationForm extends AbstractForm
{
public function init()
{
$this->add([
'name' => 'location',
'type' => LocationFieldset::class,
'options' => [
'use_as_base_fieldset' => true,
],
]);
//Call parent initializer. Adds CSRF & submit button
parent::init();
}
}
(Note: my AbstractForm does a bit more, I would suggest you have a look here, such as remove empty (child fieldsets/collections) Inputs so data is not attempted to be created in the DB)
In the LocationFieldset, give add Inputs for the Location, such as a name, and the AddressFieldset:
class LocationFieldset extends AbstractFieldset
{
public function init()
{
parent::init();
$this->add([
'name' => 'name',
'required' => true,
'type' => Text::class,
'options' => [
'label' => _('Name'),
],
]);
$this->add([
'type' => AddressFieldset::class,
'name' => 'address',
'required' => true,
'options' => [
'use_as_base_fieldset' => false,
'label' => _('Address'),
],
]);
}
}
In the AddressFieldset just add Inputs for the Address Entity. (Same as above, without the Fieldset type Input)
InputFilters
To validate the Form, you can keep it very simple:
class LocationFormInputFilter extends AbstractFormInputFilter
{
/** #var LocationFieldsetInputFilter */
protected $locationFieldsetInputFilter;
public function __construct(LocationFieldsetInputFilter $filter)
{
$this->locationFieldsetInputFilter = $filter;
parent::__construct();
}
public function init()
{
$this->add($this->locationFieldsetInputFilter, 'location');
parent::init();
}
}
(The AbstractFormInputFilter adds CSRF validator)
Notice that we simply ->add() the LocationFieldsetInputFilter, but we give it a name (2nd parameter). This name is used later in the complete structure, so it's important to both keep it simple and keep it correct. Simplest is to give it a name that one on one matches the object of the Fieldset it's supposed to validate.
Next, the LocationFieldsetInputFilter:
class LocationFieldsetInputFilter extends AbstractFieldsetInputFilter
{
/**
* #var AddressFieldsetInputFilter
*/
protected $addressFieldsetInputFilter;
public function __construct(AddressFieldsetInputFilter $addressFieldsetInputFilter)
{
$this->addressFieldsetInputFilter = $addressFieldsetInputFilter;
parent::__construct();
}
public function init()
{
parent::init();
$this->add($this->addressFieldsetInputFilter, 'address'); // Again, name is important
$this->add(
[
'name' => 'name',
'required' => true,
'filters' => [
['name' => StringTrim::class],
['name' => StripTags::class],
[
'name' => ToNull::class,
'options' => [
'type' => ToNull::TYPE_STRING,
],
],
],
'validators' => [
[
'name' => StringLength::class,
'options' => [
'min' => 3,
'max' => 255,
],
],
],
]
);
}
}
Factories
Now, you must bind them together, which is where your question about Setter injection comes from I think. This happens in the Factory.
A *FormFactory would do the following:
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$inputFilterPluginManager = $container->get('InputFilterManager');
$inputFilter = $inputFilterPluginManager->get(LocationFormInputFilter::class);
/** #var LocationForm $form */
$form = new LocationForm();
$form->setInputFilter($inputFilter); // The setter injection you're after
return $form;
}
A *FieldsetFactory would do the following (do the same for Location- and AddressFieldsets):
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
/** #var LocationFieldset $fieldset */
// name matters! Match the object to keep it simple. Name is used from Form to match the InputFilter (with same name!)
$fieldset = new LocationFieldset('location');
// Zend Reflection Hydrator, could easily be something else, such as DoctrineObject hydrator.
$fieldset->setHydrator(new Reflection());
$fieldset->setObject(new Location());
return $fieldset;
}
A *FormInputFilterFactory would do the following:
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$inputFilterPluginManager = $container->get('InputFilterManager');
/** #var LocationFieldsetInputFilter $locationFieldsetInputFilter */
$locationFieldsetInputFilter = $inputFilterPluginManager->get(LocationFieldsetInputFilter::class);
// Create Form InputFilter
$locationFormInputFilter = new LocationFormInputFilter(
$locationFieldsetInputFilter
);
return $locationFormInputFilter;
}
A *FieldsetInputFilterFactory would do the following:
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
/** #var AddressFieldsetInputFilter $addressFieldsetInputFilter */
$addressFieldsetInputFilter = $this->getInputFilterManager()->get(AddressFieldsetInputFilter::class);
$addressFieldsetInputFilter->setRequired(true);
return new LocationFieldsetInputFilter(
$addressFieldsetInputFilter
);
}
Note:
Setting an InputFilter as (not) required is something I've added here
If your InputFilter (such as AddressFieldsetInputFilter) does not have a child InputFilter, you can can skip getting the child and straight away return the new InputFilter.
I think I covered it all for a complete picture. If you have any questions about this, please comment.
What you need are Initializers from Zend Service Manager.
The initializer can be a class that is called whenever a service has been created.
In that class, you need to check the type of service that is created, and if it's appropriate type than inject whatever you want.
To register one Initializer add in config under service_manager key:
'service_manager' => [
'initializers' => [
MyInitializer::class
],
]
and then just create that class
class MyInitializer implements InitializerInterface
{
public function __invoke(ContainerInterface $container, $instance)
{
// you need to check should you inject or not
if ($instance instanceof MessageGenerator) {
$instance->setLogger($container->get('logger'));
}
}
}
You need to have registred MessageGenerator in zend-servicemanager also. In this way, when you try to retrive MessageGenerator from SM, after creation MyInitializer is called.
I'm having hard time with a weird behaviour of fileinput.
This is my form:
namespace Frontend\Form;
use NW\Form\Form;
use Zend\InputFilter;
use Zend\Form\Element;
use Zend\ServiceManager\ServiceManager;
use Zend\ServiceManager\ServiceManagerAwareInterface;
class EnrollStructure extends Form implements ServiceManagerAwareInterface
{
protected $sm;
public function __construct($name=null) {
parent::__construct("frmEnrollStructure");
$this->setAttribute("action", "/registrazione_struttura/submit")
->setAttribute('method', 'post')
->setAttribute("id", "iscrizione_struttura")
->setAttribute("class", "form fullpage");
$this->addInputFilter();
}
public function init()
{
$structureFs = $this->sm->get('Structure\Form\Fieldsets\Structure');
$structureFs->setUseAsBaseFieldset(true);
$structureFs->remove("id")
->remove("creationTime")
->remove("latLon");
$file = new Element\File("images");
$file->setAttribute('multiple', true);
$this->add($structureFs)->add($file);
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Iscriviti',
'id' => 'sbmtEnrollStructure',
'class' => 'submit_btn'
),
));
$this->setValidationGroup(
array(
'structure' =>
array(
'companyname',
'vatNumber',
'addressStreet',
'addressZip',
'addressCity',
'addressRegion',
'fax',
'publicPhone',
'publicEmail',
'website',
'status',
'ownerNotes',
'category',
'subcategory',
"facilities",
"agreeOnPolicy",
"agreeOnPrivacy",
"subscribeNewsletter",
"contact" => array("name", "surname", "email", "role", "phone"),
),
"images"
));
}
/**
* Set service manager
*
* #param ServiceManager $serviceManager
*/
public function setServiceManager(ServiceManager $serviceManager)
{
$this->sm = $serviceManager;
}
public function addInputFilter()
{
$inputFilter = new InputFilter\InputFilter();
// File Input
$fileInput = new InputFilter\FileInput('images');
$fileInput->setRequired(true);
$fileInput->getValidatorChain()
->attachByName('filesize', array('max' => "2MB"))
->attachByName('filemimetype', array('mimeType' => 'image/png,image/x-png,image/jpg,image/jpeg'))
->attachByName('fileimagesize', array('maxWidth' => 2048, 'maxHeight' => 2048));
$inputFilter->add($fileInput);
$this->setInputFilter($inputFilter);
}
}
Basically, I mainly use a fieldset which contains most of the data I request to the user, plus a File input field.
This is the Fieldset Structure: (most important parts..)
use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\ServiceManager\ServiceManager;
use Zend\ServiceManager\ServiceManagerAwareInterface;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use Zend\Validator\Identical;
use Zend\Validator\NotEmpty;
use Zend\Validator\Regex;
use Zend\Validator\StringLength;
class Structure extends Fieldset implements InputFilterProviderInterface, ServiceManagerAwareInterface
{
protected $sm;
public function __construct()
{
parent::__construct('structure');
}
public function init()
{
$this->setHydrator(new DoctrineHydrator($this->_entityManager(),'Structure\Entity\Structure'));
$this->setObject($this->sm->getServiceLocator()->get("Structure_Structure"));
$id = new Element\Hidden("id");
$name = new Element\Text("companyname");
$name->setLabel("Ragione Sociale");
...........
}
public function getInputFilterSpecification()
{
return array
(
"id" => array(
"required" => false,
),
"companyname" => array(
"required" => true,
"validators" => array(
array('name' => "NotEmpty", 'options' => array("messages" => array( NotEmpty::IS_EMPTY => "Inserire la ragione sociale")))
),
),
.....
}
}
This is my controller:
public function submitAction()
{
try {
$this->layout("layout/json");
$form = $this->getForm('Frontend\Form\EnrollStructure');
//$form->addInputFilter();
$structure = $this->getServiceLocator()->get("Structure_Structure");
$viewModel = new ViewModel();
$request = $this->getRequest();
if ($request->isPost())
{
$post = array_merge_recursive
(
$request->getPost()->toArray(),
$request->getFiles()->toArray()
);
$form->setData($post);
if ($form->isValid())
{
$structure = $form->getObject();
$contact = $structure->getContact();
$this->getServiceLocator()->get('Structure_ContactService')->save($contact);
$files = $request->getFiles()->toArray();
if(isset($files['images']))
{
$count = 3;
foreach($files['images'] as $pos => $file)
{
$fpath = $this->getServiceLocator()->get('RdnUpload\Container')->upload($file);
if(!empty($fpath))
{
if(--$count ==0) break;
$asset = $this->getServiceLocator()->get("Application_AssetService")->fromDisk($fpath, $file['name']);
$this->getServiceLocator()->get("Application_AssetService")->save($asset);
$structure->addImage($asset);
}
}
}
$this->getServiceLocator()->get('Structure_StructureService')->save($structure);
$retCode = RetCode::success(array("iscrizione_struttura!" => array("form_submit_successfull")), true);
}
else
{
$messages = $form->getMessages();
if(empty($messages))
$retCode = RetCode::error(array("iscrizione_struttura" => array("need_at_least_one_file" => "missing file")), true);
else
$retCode = RetCode::error(array("iscrizione_struttura" => $messages), true);
}
$viewModel->setVariable("retcode", $retCode);
return $viewModel;
}
} catch(Exception $e)
{
throw $e;
}
}
The strange thing is that if i remove from the field "images" the "multiple" attribute everything works fine, causing the form not to validate and i get this message:
[images] => Array
(
[fileUploadFileErrorFileNotFound] => File was not found
)
While, if i set the attribute multiple, and the user does not upload a file i get no error, but the form gets invalidated (this is the reason for this "bad" code in my controller:)
$messages = $form->getMessages();
if(empty($messages))
$retCode = RetCode::error(array("iscrizione_struttura" => array("need_at_least_one_file" => "missing file")), true);
else
$retCode = RetCode::error(array("iscrizione_struttura" => $messages), true);
I found the problem was caused by the Jquery form plugin, without it it works fine. :( In case somebody needs, I think the correct action code can be found here (I haven't tryied it anyway)
https://github.com/cgmartin/ZF2FileUploadExamples/blob/master/src/ZF2FileUploadExamples/Controller/ProgressExamples.php
I have some sample code with 2 tabs. One shows a "form" and the other a "list" (Sample 1.5-1), I want to combine them.
I want to show the "form" tab with a "list" view at the bottom (after submit button). I am getting stuck on how to show this.
Inside IndexController, in the ->getRequest->isPost() area, I try to create and fill up the $list (same as the "list" tab example code):
$list=$this->_getListRandom();
$this->view->list = $list;
Then inside of form.phtml, I append:
<h1>My Report Data></h1>
<?php echo $this->list; ?>
I can see the "My Report Data" text in the web page, so I know I am getting to the right area in the code!
But, I get an error from pm_View_Helper_render::renderList() that it must be an instance of pm_View_List_Simple.
I am trying to create both a pm_Form_Simple and pm_View_List_Simple in the same $this, but not
sure if it is allowed or how to do it.
Thanks for any suggestions!

and here the result:
I am new to this these technologies, so might not be asking to do this the easiest way, but: I want to create a form and ask for an ID value. Once submit is pressed, I want to take that ID, make an external XML call and then show the XML data. I am stuck on if I can do this in a single url:https://plesk.local:8443/modules/example/index.php/index/form. I would like to have both the form and the list data on the same page, so I can update the ID, press submit and see the new data...over and over...
I am trying to modify the basic "Example1" that Plesk includes. I can modify it and test it, but stuck on exactly how POST works. Ideally I want to have $this->view->form to have both a pm_Form_Simple and pm_View_List_Simple on the same $form view (if this makes sense).
So looking for help on
1) Can I use the same URL and handle the POST/GET from it
2) Can I have both a form and simple list on the same page?
thx!!!!!

Yes
Yes
I'm not expirienced in zend, so it just try, I suggest to replace formAction() with following code:
public function formAction()
{
// Init form here
$form = new pm_Form_Simple();
$form->addElement('text', 'exampleText', array(
'label' => 'Example Text',
'value' => pm_Settings::get('exampleText'),
'required' => true,
'validators' => array(
array('NotEmpty', true),
),
));
$form->addControlButtons(array(
'cancelLink' => pm_Context::getModulesListUrl(),
));
if ($this->getRequest()->isPost() && $form->isValid($this->getRequest()->getPost())) {
// Form proccessing here
pm_Settings::set('exampleText', $form->getValue('exampleText'));
$this->_status->addMessage('info', 'Data was successfully saved.');
$list = $this->_getListRandom();
$this->view->list = $list;
$this->view->form = $form;
// Redirects happens on next string, maybe you need to add something to getBaseUrl()
$this->_helper->json(array('redirect' => pm_Context::getBaseUrl()));
}
$this->view->form = $form;
}
Im having a problem with the addAction in my CRUD application. On the controller the logic does not pass the $form->isValid() verification but the form does not show any error message.
I tried with this (Thanks Sam):
foreach($form->get('product')->getElements() as $el)
{
echo $el->getName()." = ".$el->getValue()." > ".$el->getMessages()." <br/>";
}
That only show the name and value of the field, but not the error message.
I've tried letting the form totally blank and it fire "Value is required and can't be empty" error messages, but then, i fill each field one by one until i don't get more error messages but the form still invalid.
My form has a Product Fieldset as a base fieldset and a submit button. Inside Product Fieldset i have an ID field, a name field, a price field and a Brand Fieldset. Inside my Brand Fieldset i have a id field. Like this:
ProductForm:
class ProductForm extends Form
{
public function init()
{
// we want to ignore the name passed
parent::__construct('product');
$this->setName('product');
$this->setAttribute('method', 'post');
$this->add(array(
'name' => 'product',
'type' => 'Administrador\Form\ProductFieldset',
'options' => array(
'use_as_base_fieldset' => true
),
));
$this->add(array(
'name' => 'submit',
'type' => 'Submit',
'attributes' => array(
'value' => 'Add',
'id' => 'submitbutton',
),
));
}
}
ProductFieldset:
class ProductFieldset extends Fieldset implements ServiceLocatorAwareInterface
{
protected $serviceLocator;
function __construct($name = null)
{
parent::__construct('product_fieldset');
$this->setHydrator(new ArraySerializableHydrator());
$this->setObject(new Product());
}
public function init()
{
$this->add(array(
'name' => 'id',
'type' => 'Hidden',
));
$this->add(array(
'name' => 'name',
'type' => 'Text',
'options' => array(
'label' => 'Name',
),
));
$this->add(array(
'name' => 'price',
'type' => 'Text',
'options' => array(
'label' => 'Price',
),
));
$this->add(array(
'name' => 'brand',
'type' => 'BrandFieldset',
));
}
public function setServiceLocator(ServiceLocatorInterface $sl)
{
$this->serviceLocator = $sl;
}
public function getServiceLocator()
{
return $this->serviceLocator;
}
}
BrandFieldset:
class BrandFieldset extends Fieldset
{
function __construct(BrandTable $brandTable)
{
parent::__construct('brand_fieldset');
//$this->setHydrator(new ClassMethodsHydrator(false))->setObject(new Brand());
$this->setHydrator(new ArraySerializableHydrator());
$this->setObject(new Brand());
$brandSelectOptionsArray = $brandTable->populateSelectBrand();
$this->add(array(
'name' => 'id',
'type' => 'Select',
'options' => array(
'label' => 'Brand',
'empty_option' => 'Please select a brand',
'value_options' => $brandSelectOptionsArray,
),
));
}
}
This is my new Form statement in the addAction:
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Administrador\Form\ProductForm');
Inside my model 'Product' i have the inputFilters, required filter for 'id' field, required filter for 'name' field. And for the Brand field i created other inputFilter and added it to the main inputFilter:
$brandFilter->add($factory->createInput(array(
'name' => 'id',
'required' => true,
'filters' => array(
array('name' => 'Int'),
),
)));
$inputFilter->add($brandFilter, 'brand');
The weird behavior is that my editAction works fine and has the same logic.
Is it there any form of echoing an internal error message from the form, something that helps me to understand WHY the form is not valid.
EDIT 2013-06-01
Here is my full Controller:
class ProductController extends AbstractActionController
{
protected $productTable;

My case was I passed wrong input filter. isValid returns false, but $form->getMessages() is empty. Form OrderForm had the following:
$form->setInputFilter(new \Application\Form\UserInputFilter($er));
When I changed UserInputFilter to OrderInputFilter it works.
Well, I got the answer :D
This is how the addAction should be:
public function addAction()
{
$formManager = $this->serviceLocator->get('FormElementManager');
$form = $formManager->get('Administrador\Form\ProductForm');
$form->get('submit')->setValue('Add');
$product = new Product();
$product->brand = new Brand();
$form->bind($product); // I need to bind the product to the form to pass the isValid() validation
$request = $this->getRequest();
if ($request->isPost()) {
$form->setInputFilter($product->getInputFilter());
$form->setData($request->getPost());
if ($form->isValid()) {
$product = $form->getData();
$this->getProductTable()->saveProduct($product);
// Redirect to list of products
return $this->redirect()->toRoute('product');
}
}
return new ViewModel(array(
'form' => $form,
));
}
Apparently i needed to bind and empty product object to the form to be able to pass the isValid() validation. After that i retrieve a product object from the $form->getData().
You can also do: $form->setBindOnValidate(false);
