How to show error messages in View using Phalcon

Question

I need to show the error messages in View

Here is my code:

This is my form code:

public function initialize() {

        $name = new Text('name', array(
            'class' => 'form-control',
            "placeholder" => "Type your name"
        ));

        $name->addValidators(array(
            new PresenceOf(array(
                'message' => 'Please enter your username.',
            )),
        ));

        $this->add($name);

    }

Here is my html code:

<form method="post" action="user">

    <p>
        <label>
            Name
        </label>
        <?php echo $userForm->render("name"); ?>
    </p>


    <p>
        <input type="submit" value="Save" />
    </p>

</form>

Here is my controller file code:

public function indexAction()
    {
        $userform = new UserForm();
        $this->view->userForm = $userform;
        if($this->request->isPost()) {
            if($userform->isValid($_POST)) { 

            }

        }
    }

Any help is greatly appreciated. Thanks in advance.

Will quote the docs.

By default messages generated by all the elements in the form are joined so they can be traversed using a single foreach, you can change this behavior to get the messages separated by the field:

foreach ($userform->getMessages(false) as $attribute => $messages) {
    echo "Messages generated by ", $attribute, ":", "\n";

    foreach ($messages as $message) {
        echo $message, "<br>";
    }
}

Or get specific messages for an element:

$messages = $userform->getMessagesFor("name");
foreach ($messages as $message) {
    echo $message, "<br>";
}
