I have a form witch contains embededForms.
the Post-Validator:
$this->validatorSchema->setPostValidator(
new sfValidatorCallback(
array('callback' => array($this, 'myPostValidator'))
)
);
I throw an error in the myPostValidator method:
$error = new sfValidatorError($validator, 'invalid ' . $values['embededform1']['field']);
throw new sfValidatorErrorSchema($validator, array('field' => $error));
now I get an global error for the root-form.
I want to display the error next to the correct field.
$values['embededform1']['field']
My first suggestion would be to add the post validator in the embedded form. While embedding it will copy the validator to the container form, and your code for throwing the exception should work as expected.
Alternative you can try the following in the callback on your container form:
$error = new sfValidatorError($validator, 'invalid');
$errorschema = new sfValidatorErrorSchema($validator, array('field' => $error));
throw new sfValidatorErrorSchema($validator, array('embeddedformname' => $errorschema));
$error = new sfValidatorError($validator, 'invalid');
$errorschema = new sfValidatorErrorSchema($validator, array('field' => $error));
throw new sfValidatorErrorSchema($validator, array('embeddedformname' => $errorschema));
this worked for me.

My app is creating a new entry via a POST request in an api end point.
Now, if any validation is failed then instead of returning an error json, laravel 5.3 is redirecting the request to home page.
Here is my controller:
public function create( Request $request )
{
$organization = new Organization;
// Validate user input
$this->validate($request, [
'organizationName' => 'required',
'organizationType' => 'required',
'companyStreet' => 'required'
]);
// Add data
$organization->organizationName = $request->input('organizationName');
$organization->organizationType = $request->input('organizationType');
$organization->companyStreet = $request->input('companyStreet');
$organization->save();
return response()->json($organization);
}
If there is no issue with validation then the entity will be successfully added in the database, but if there is issue with validating the request then instead of sending all the error messages as a json response it redirects back to the home page.
How i can set the validate return type to json, so with every request if the validation failed then laravel will send all the error messages as json by default.
You can do your validation as:
$validator = \Validator::make($request->all(), [
'organizationName' => 'required',
'organizationType' => 'required',
'companyStreet' => 'required'
]);
if ($validator->fails()) {
return response()->json($validator->errors(), 422)
}
The validation used in the question looks as per the recommendation by laravel. The reason of redirection is that it throws an exception which you can easily catch using the code below. So it's better to use the recommended way of code instead of re-writing framework's code again :)
public function create( Request $request )
{
$organization = new Organization;
// Validate user input
try {
$this->validate($request, [
'organizationName' => 'required',
'organizationType' => 'required',
'companyStreet' => 'required'
]);
} catch (ValidationException $e) {
return response()->json($e->validator->errors(), 422);
}
// Add data
$organization->organizationName = $request->input('organizationName');
$organization->organizationType = $request->input('organizationType');
$organization->companyStreet = $request->input('companyStreet');
$organization->save();
return response()->json($organization, 201);
}
I am trying to render a form from a string in Symfony2 and get the result in a variable.
I tried this solution, Symfony 2 Twig form functions not available but I am getting an error (service 'twig.form.renderer' not avaliable). So I changed the addExtension part (not sure about the classes).
Here is my code :
$env = new \Twig_Environment(new \Twig_Loader_String());
$rendererEngine = new \Symfony\Bridge\Twig\Form\TwigRendererEngine();
$env->addExtension(new \Symfony\Bridge\Twig\Extension\FormExtension(new \Symfony\Bridge\Twig\Form\TwigRenderer($rendererEngine)));
$form = $this->createFormBuilder()->add('testField', 'text');
$form = $form->getForm()->createView();
return $env->render(
'{{ form(form) }}',
array('form' => $form)
);
Now I am getting "Fatal error: Uncaught exception 'Symfony\Component\Form\Exception\LogicException' with message 'No block "form" found while rendering the form"
For twig templation i use this code:
$twig = $this->container->get('twig');
$twig->initRuntime();
return JsonResponse::create(array(
'success' => false,
'form' => $twig->getExtension('form')->renderer->searchAndRenderBlock($form->createView(), 'widget'),
));
for php template engine:
$this->container->get('templating.helper.form')->widget($form->createView());
You should include form_div_layout where form block is defined.
my problem is, every time I click in the paginator link in the view, the controller returns me this error:
Syntax error, unexpected EOF
What is this? EOF?
My controller:
$domicilios = Domicilios::find();
$paginator = new \Phalcon\Paginator\Adapter\Model(
array(
"data" => $domicilios,
"limit"=> 5,
"page" => $currentPage
)
);
$pagina = $paginator->getPaginate();
$this->view->setVar("estado", $estado);
$this->view->setVar("pagina", $pagina);
The content in the model Domicilios is returning right, but why the paginator keeps returning this error?
Thanks in advance!
EOF is end of file. there might be several issues. 1stly if you upload this file to server, there might be problems with upload process and file is not fully uploaded and you have broken end of file (EOF).
try converting your php file to utf8. you can do it with notepad++ and many other programs.
here are my working pagination:
$page = $this->request->get('page', 'int', 1);
$this->view->page = $page;
if ($page < 1) {
$page = 1;
}
$user = $this->session->get('auth');
$questions = Model_UserQuestion::find(array(
'user_id=:user_id:',
'bind' => array('user_id' => $user['id']),
"order" => "id DESC",
));
// Create a Model paginator, show 10 rows by page starting from $currentPage
$paginator = new \Phalcon\Paginator\Adapter\Model(
array(
"data" => $questions,
"limit" => $this->config->application->itemsPerPage,
"page" => $page
)
);
$page = $paginator->getPaginate();
$this->view->questions = $page->items;
notice that to get items you have to use this:
$page->items
The CakeEmail help page states that the data option has been added as of 2.4, so you no long have to have a physical file to add an attachment to an email.
I've got the following code:
$Email->from(array($this->Session->read('Auth.User.email') => $this->Session->read('Auth.User.name')))
->to($this->request->data['email-to'])
->subject($this->request->data['email-subject'])
->attachments(array('attachement1.pdf', array('data' => $pdf)))
->send($this->request->data['email-message']);
But whenever I run that I get an Internal Error saying File Not Found: "".
I had a look at the source code (which I'm beginning to learn is often more useful than reading the documentation!): https://github.com/cakephp/cakephp/blob/master/lib/Cake/Network/Email/CakeEmail.php
Changing my code to:
$Email = new CakeEmail('default');
$Email->from(array($this->Session->read('Auth.User.email') => $this->Session->read('Auth.User.name')))
->to($this->request->data['email-to'])
->subject($this->request->data['email-subject'])
->attachments(array('attachement1.pdf' => array('data' => $pdf, 'mimetype' => 'application/pdf')))
->send($this->request->data['email-message']);
Notice on the attachments line, the array is assigned to the filename variable, rather than passed in as a parameter!
For completeness, if anyone else is reading this and is wondering how I am generating my PDF with CakePDF:
// Create PDF for attachment
$CakePdf = new CakePdf();
$CakePdf->template('claim', 'default');
//get the pdf string returned
$pdf = $CakePdf->output();
I've a password form field (not mapped to User password) to be used in a change password form, along with two other (mapped) fields, first and last.
I've to add validators on the fly: if value for password is blank then no validation should occur. Otherwise a new MinLength and MaxLength validators should be added.
Here is what i've done so far: create the repeated password field, add a CallbackValidator and return if $form->getData() is null.
Then, how can i add validators for minimum and maximum length to $field?
$builder = $this->createFormBuilder($user);
$field = $builder->create('new_password', 'repeated', array(
'type' => 'password',
'first_name' => 'Password',
'second_name' => 'Confirm password',
'required' => false,
'property_path' => false // Not mapped to the entity password
));
// Add a callback validator the the password field
$field->addValidator(new Form\CallbackValidator(function($form) {
$data = $form->getData();
if(is_null($data)) return; // Field is blank
// Here password is provided and match confirm, check min = 3 max = 10
}));
// Add fields to the form
$form = $builder
->add('first', 'text', array('required' => false)) // Mapped
->add('last', 'text', array('required' => false)) // Mapped
->add($field) // Not mapped
->getForm();
Oh well, found a solution myself after a few experiments.
I'm going to leave this question unanswered for a couple of days as one can post a better solution, that would be really really welcome :)
In particular, i found the new FormError part redundat, don't know if there is a better way to add the error to the form. And honestly, don't know why new Form\CallbackValidator works while new CallbackValidator won't.
So, don't forget to add use statements like these:
use Symfony\Component\Form as Form, // Mendatory
Symfony\Component\Form\FormInterface,
Symfony\Component\Validator\Constraints\MinLength,
Symfony\Component\Validator\Constraints\MinLengthValidator;
And the callback is:
$validation = function(FormInterface $form) {
// If $data is null then the field was blank, do nothing more
if(is_null($data = $form->getData())) return;
// Create a new MinLengthValidator
$validator = new MinLengthValidator();
// If $data is invalid against the MinLength constraint add the error
if(!$validator->isValid($data, new MinLength(array('limit' => 3)))) :
$template = $validator->getMessageTemplate(); // Default error msg
$parameters = $validator->getMessageParameters(); // Default parameters
// Add the error to the form (to the field "password")
$form->addError(new Form\FormError($template, $parameters));
endif;
};
Well, and this is the part i can't understand (why i'm forced to prefix with Form), but it's fine:
$builder->get('password')->addValidator(new Form\CallbackValidator($validation));
addValidator was deprecated and completly removed since Symfony 2.3.
You can do that by listening to the POST_SUBMIT event
$builder->addEventListener(FormEvents::POST_SUBMIT, function ($event) {
$data = $event->getData();
$form = $event->getForm();
if (null === $data) {
return;
}
if ("Your logic here") {
$form->get('new_password')->addError(new FormError());
}
});
