Hi guys, I have a question about form validation, why is it that validation messages still appear even if I already enter the right value in a form, i.e. an email textbox , i entered [email protected] and hit the send button but still error message is there instead it should disappear. I want to achieve this by using phalcon form validation and not by javascript or jquery. thnks :)

here is my code

<?php

use \Phalcon\Forms\Form,
    \Phalcon\Forms\Element\Text,
    \Phalcon\Forms\Element\Password,
    \Phalcon\Forms\Element\Email,
    \Phalcon\Forms\Element\Radio,
    \Phalcon\Forms\Element\Select,
    \Phalcon\Forms\Element\Submit,
    \Phalcon\Validation,
    \Phalcon\Validation\ValidatorInterface,
    \Phalcon\Validation\Validator\PresenceOf,
    \Phalcon\Validation\Validator\StringLength,
    \Phalcon\Validation\Validator\Confirmation,
    \Phalcon\Validation\Message,
    \Phalcon\Escape,
    \Phalcon\Mvc\Model,
    \Phalcon\Db\RawValue,
    \Phalcon\Db\Column,
    \Phalcon\Http\Request as FormRequest;

class RegisterForm extends Form{

    private static $reg_frm = [];
    private static $request;

    public function initialize(){

        /* Fullname */
        self::$reg_frm['fullname'] = new Text('fullname',[
                                        'maxlength'     =>  255,
                                        'placeholder'   =>  '',
                                        'class'         =>  'form-control txt-name',
                                        'autocomplete'  =>  'off',

I don't know if this will be a solution to your problem but normally the way you define and use forms is a bit different.

First you have to create the form object e.g.

<?php
class BlogForm extends Form {
    public function initialize($post)
    {
        // field for author of blog post
        $field = new \Phalcon\Forms\Element\Text('author');

        $field->addValidator(new \Phalcon\Validation\Validator\PresenceOf(array(
            'message' => 'The name is required'
        )));

        $this->add($field);

        // more fields ...
    }
}

And then in the controller you use this form e.g.

<?php
class BlogController extends \Phalcon\Mvc\Controller {

    // ...
    public function editAction($id) {
        $post = Blog::findFirstById($id);

        // get instance of form
        $form = new BlogForm($post);

        // check if form was posted
        if ($this->request->isPost()) {

            // validation of post data against form definition
            if ($form->isValid($this->request->getPost()) != false) {

                $form->bind($this->request->getPost(), $post);

                if ($post->save()) {
                    return $this->response->redirect('blog/show/' . $id);
                }
            } else {

                // if validation fails write messages to flash service
                foreach ($form->getMessages() as $message) {
                    $this->flash->error((string) $message);
                }
            }
        }

        $this->view->post = $post;
        $this->view->form = $form;
    }

    // ...
}
