I have placed this class file called 'My_Form_validation.php' into 'application/core' and I have also tried placing it in 'application/libraries'.
In my controller I am using
$this->form_validation->set_rules('user_postcode', 'Postcode', 'valid_postcode|trim|required|xss_clean');
This is whats in My_Form_validation.php - the actual logic is not in question here because I have a couple of options to actually validate the postcode. What I need help with is understanding why it is not loading or getting called!
My CI version is
define('CI_VERSION', '2.0.2');
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**

Because you're extending a CodeIgniter library and not a core component, you want to place that in application/libraries (not application/core).
And of course, don't forget to load the Form_validation library within your controller code.
$this->load->library('form_validation');
Other things to check:
Filename case sensitivity (MY_Form_validation.php loads while My_Form_validation.php won't)
Class name case sensitivity (class MY_Form_validation extends CI_Form_validation)
Reference material:
Extending Core Classes
Extending Native Libraries
You have to add $rules on your __construct method and also pass this to parent constructor
eg:
function __construct($rules = array())
{
parent::__construct($rules);
}
Look at Form_validation and provide same variables.

What is the most straightforward way to get the current category in the view? I notice that there is a getTerm method in the Term class:
public function getEntity()
{
return $this->getTerm();
}
/**
* Returns the current Wordpress category
* This is just a wrapper for getCurrentCategory()
*
* #return \FishPig\WordPress\Model\Term
*/
public function getTerm()
{
if (!$this->hasTerm()) {
$this->setTerm($this->_registry->registry(Term::ENTITY));
}
return $this->_getData('term');
}
However if I try to utilize the method within a template (for example, the default post list wrapper.phtml template which utilizes the Term block in the layout) it throws an error:
<?php echo $this->getTerm() ?>
Recoverable Error: Object of class FishPig\WordPress\Model\Term could
not be converted to string in
I'm probably just missing something simple, any help would be greatly appreciated. Thanks!
$term = \Magento\Framework\App\ObjectManager::getInstance()
->get('Magento\Framework\Registry')
->registry('wordpress_term');
I’m developing a form in zf2 and I want to calculate a value based upon user input and set it in a field after the form has validated. In the form, there is a firstName field and a lastName field; and I want to use the validated input to calculate a value to populate in a fullName field.
I assume I want to set the value something like this, but haven’t found the right code for setting the "element" that gets sent to the database:
public function addAction()
{
$objectManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$form = new AddMemberForm($objectManager);
$member = new Member();
$form->bind($member);
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
if ($form->isValid()) {
// develop full name string and populate the field
$calculatedName = $_POST['firstName'] . " " . $_POST['lastName'];
$member->setValue('memberFullName', $calculatedName);
$this->getEntityManager()->persist($member);
$this->getEntityManager()->flush();
return $this->redirect()->toRoute('admin-members');
}
}
return array('form' => $form);
}
Doctrine's built-in Lifecycle Callbacks are perfectly fits for handling such requirement and I strongly recommend to use them.
You just need to correctly annotate the entity.
For example:
<?php
/**
* Member Entity
*/
namespace YourNamespace\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Event\LifecycleEventArgs;
/**
* #ORM\Table(name="members")
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class Member
{
// After all of your entity properies, getters and setters... Put the method below
/**
* Calculate full name on pre persist.
*
* #ORM\PrePersist
* #return void
*/
public function onPrePersist(LifecycleEventArgs $args)
{
$this->memberFullName = $this->getFirstName().' '.$this->getLastName();
}
}
With this way, memberFullName property of the entity will be automatically populated using first and last names on entity level just before persisting.
Now you can remove the lines below from your action:
// Remove this lines
$calculatedName = $_POST['firstName'] . " " . $_POST['lastName'];
$member->setValue('memberFullName', $calculatedName);
Foozy’s excellent answer provides a solution that works for an add action, and the response to my comment directed me to the following solution that works for both add and edit actions:
<?php
/**
* Member Entity
*/
namespace YourNamespace\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Event\PreFlushEventArgs;
/**
* #ORM\Table(name="members")
* #ORM\Entity
*/
class Member
{
// After all of your entity properies, getters and setters... Put the method below
/**
* Calculate full name on pre flush.
*
* #ORM\PreFlush
* #return void
*/
public function onPreFlush(PreFlushEventArgs $args)
{
$this->memberFullName = $this->getFirstName().' '.$this->getLastName();
}
}
I've got some issues with Symfony's form validation handling. I'd like to validate a form bound to an entity based on its data. There are quite a bunch of information how to dynamically modify the form fields using FormEvents. What I'm missing on this topic is how to control/modify the validation.
My simplified use case is:
A user can add an event to a calendar.
The validation checks if there's already an event.
If there's a collision, the validation will throw an error.
The user should now be able to ignore this error/warning.
The validation is implemented as a Validator with Constraint::CLASS_CONSTRAINT as the target (as it's taking some more stuff into account).
I tried to:
Hack around the validation groups, but couldn't find access to the entity wide validators.
Hack around the FormEvents and add an extra field like "Ignore date warning".
Hack around the submit button to change it to something like "Force submit".
... but never found a working solution. Even simpler hacks with a single property based validator didn't work out. :(
Is there a Symfony way to dynamically control the validation?
Edit: My code looks like this:
use Doctrine\ORM\Mapping as ORM;
use Acme\Bundle\Validator\Constraints as AcmeAssert;
/**
* Appointment
*
* #ORM\Entity
* #AcmeAssert\DateIsValid
*/
class Appointment
{
/**
* #ORM\Column(name="title", type="string", length=255)
*
* #var string
*/
protected $title;
/**
* #ORM\Column(name="date", type="date")
*
* #var \DateTime
*/
protected $date;
}
The validator used as a service:
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
/**
* Validates the date of an appointment.
*/
class DateIsValidValidator extends ConstraintValidator
{
/**
* {#inheritdoc}
*/
public function validate($appointment, Constraint $constraint)
{
if (null === $date = $appointment->getDate()) {
return;
}
/* Do some magic to validate date */
if (!$valid) {
$this->context->addViolationAt('date', $constraint->message);
}
}
}
The corresponding Constraint class is set to target the entity class.
use Symfony\Component\Validator\Constraint;
/**
* #Annotation
*/
class DateIsValid extends Constraint
{
public $message = 'The date is not valid!';
/**
* {#inheritdoc}
*/
public function getTargets()
{
return self::CLASS_CONSTRAINT;
}
/**
* {#inheritdoc}
*/
public function validatedBy()
{
return 'acme.validator.appointment.date';
}
}
Edit 2: Try with FormEvents... I also tried all the different events.
$form = $formFactory->createBuilder()
->add('title', 'text')
->add('date', 'date')
->addEventListener(FormEvents::WHICHONE?, function(FormEvent $event) {
$form = $event->getForm();
// WHAT TO DO HERE?
$form->getErrors(); // Is always empty as all events run before validation?
// I need something like
if (!$dateIsValid) {
$form->setValidationGroup('ignoreWarning');
}
});
Edit 3: Constraint are correctly declared. That's not the issue:
services:
validator.acme.date:
class: AcmeBundle\Validator\Constraints\DateValidator
arguments: ["#acme.other_service"]
tags:
- { name: validator.constraint_validator, alias: acme.validator.appointment.date }
Validation is done on the entity, all Forms does is execute the Object's validations.
You can choose groups based on submitted data
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'validation_groups' => function(FormInterface $form) {
$data = $form->getData();
if (Entity\Client::TYPE_PERSON == $data->getType()) {
return array('person');
} else {
return array('company');
}
},
));
}
I have had issues when using this approach on embedded forms && cascade-validation
Edit: using flash to determine if validation must take place.
// service definition
<service id="app.form.type.callendar" class="%app.form.type.callendar.class%">
<argument type="service" id="session" />
<tag name="form.type" alias="my_callendar" />
</service>
// some controller
public function somAvtion()
{
$form = $this->get('app.form.type.callendar');
...
}
// In the form
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'validation_groups' => function(FormInterface $form) {
$session = $form->getSession();
if ($session->getFlashBag()->get('callendar_warning', false)) {
return array(false);
} else {
return array('Validate_callendar');
}
},
));
}
How does your user interact with the application to tell it to ignore the warning? Is there some kind of additional button?
In that case you could simply check the button used for submitting the form or add some kind of hidden field (ignore_validation) etc.
Wherever you end up getting that user input from (flash and dependency injection, based on submitted data etc.), I would then use validation groups and a closure to determine what to validate (just like juanmf explained in his answer).
RE your second approach (Form Events), you can add a priority to event listeners: As you can see in Symfony's Form Validation Event Listener, they use FormEvents::POST_SUBMIT for starting the validation process. So if you just add an event listener, it gets called before the validation listener and so no validation has happened yet.
If you add a negative priority to your listener, you should be able to also access the form validation errors:
$builder->addEventListener(FormEvents::POST_SUBMIT, function(){...}, -900);
Old question but...
I would first add a field (acceptCollision) in the form as suggested by you and other answers above.
Then you validator can do something like:
public function validate($appointment, Constraint $constraint)
{
if (null === $date = $appointment->getDate()) {
return;
}
if ($appointment->getAcceptCollision()) {
$valid = true;
} elseif (
// Check Unicity of the date (no collision)
) {
$valid = true;
} else {
$valid = false;
}
if (!$valid) {
$this->context->addViolationAt('date', $constraint->message);
}
}
I think you run into a problem because you are using the wrong concept. The decision which validation should be running belongs to the controller, not the validator.
So I would simply check in the controller which submit button is pressed (or weither there is a checkbox checked) and switch validation groups. However the form should be visually different, so I would probably create 2 forms for both states (both extend a base one or one form type that use options).
Can anybody tell me whether its posible to override doctrine2 persistentobject magic getters\setters? i'd like to do the below:-
public function setDob($dob)
{
$this->dob= new \Date($date);
}
however my entity is defined as:-
use Doctrine\Common\Persistence\PersistentObject;
use Doctrine\ORM\Mapping as ORM;
/**
* User
*
* #ORM\Table(name="user")
* #ORM\Entity(repositoryClass="Ajfit\Repository\User")
* #ORM\HasLifecycleCallbacks
*/
class User extends \Doctrine\Common\Persistence\PersistentObject
{
/**
* #var date $dob
*
* #ORM\Column(name="dob", type="date")
*/
protected $dob;
}
the public function setDob does not get called when I create the entity using:-
public function getNewRecord() {
return $this->metadata->newInstance();
}
I get the below error:-
Notice:- array to string conversion ...Doctrine\DBAL\Statement.php on line 98
Any help would be much apprieciated.
Thanks
Andrew
__call of PersistentObject#__call will not be called if you defined the setDob method.
What you're doing there is creating a new instance via metadata. What you are doing there is probably assuming that __construct or any setter/getter should be called by the ORM. Doctrine avoids to call any methods on your object when generating it via metadata/hydration (check ClassMetadataInfo#newInstance to see how it is done) as it does only know it's fields.
This allows you to be completely independent from Doctrine's logic.
About the notice, that is a completely different issue coming from Doctrine\DBAL\Statement, which suggests me that you have probably some wrong parameter binding in a query. That should be handled separately.
I am trying to create something with extbase, but the error-message I get is not very helpful. I took the blog_example extension as a guide. A (maybe) important difference is: I don't have a database table because I want to write a custom domain repository that connects to an external servive through REST.
The actual error message (displayed above the plugin, not as an exception message):
An error occurred while trying to call Tx_MyExt_Controller_SubscriptionController->createAction()

Facts
Adding $subscriber = null removes the message. But $subscriber is null then
A var_dump($this->request->getArguments()); displays the form's fields
There is an index action, and it is also the first action defined in ext_localconf.php
The hints and solutions I found aren't working for me, so I hope someone can guide me into the right direction.
I've got the same bug.
If you pass an Model as argument to an method, it will also validate the model fields.
I've had this annotation on my model property:
/**
*
* #var \string
* #validate NotEmpty
*/
It validates the "#validate" annotation.
The field in the database was empty so i got the error message
An error occurred while trying to call ...
It would be good if there was a better error message.
You need to customize the validation annotation or verify that the property is not empty in the database
Hope it helps somebody
In addtion: check any Validations in your Model and your TCA. If a field is marked as #validate NotEmpty in your Model and is not marked appropriately in the TCA, a record can be saved ignoring the #validate settings in the Model. This can happen if you change the Model and/or TCA after creating records.
An example:
Field 'textfield' is set to not validate, both in the TCA and the Model. You create a new record and save it without filling in the field 'textfield' (you can, it is not set to validate). You then change the Model setting 'textfield' to #validate NotEmpty and then try to show the record on the FE, you will get the error.
The solution for that example:
Simply remove the validation in your Model OR check validations in the TCA and Model so that they work together.

A German blog post covers this solution: http://www.constantinmedia.com/2014/04/typo3-extbase-an-error-occurred-while-trying-to-call-anyaction/
just override the template method getErrorFlashMessage in yout controller to provide a custom error message...
/**
* A template method for displaying custom error flash messages, or to
* display no flash message at all on errors. Override this to customize
* the flash message in your action controller.
*
* #return string|boolean The flash message or FALSE if no flash message should be set
* #api
*/
protected function getErrorFlashMessage() {
return 'An error occurred while trying to call ' . get_class($this) . '->' . $this->actionMethodName . '()';
}
classic case of "start over from scratch and it works, and if you compare it you have the same code, though".
I updated the code in the question, maybe it helps someone.
