Phalcon Forms

It handles creation and maintenance of forms in the web application. Now, as we have designed a basic web-app before we would be adding signup form.

Designing Signup form

Change the index.phtml viewfile, add the signup page link as a controller.

app/views/index/index.phtml

  <?php  echo “<h1>Hello!</h1>”;  echo PHP_EOL;  echo PHP_EOL;  echo $this->tag->linkTo(      “signup”,      “Sign Up Here!”  );  

OUTPUT:

Now, we write the signup controller

app/controllers/SignupController.php

  <?php  use PhalconMvcController;  class SignupController extends Controller  {      public function indexAction()   {   }  }  ?>  

Initializing Form

In this form, we provide the form definition i.e. structure of form is provided.

app/views/signup/index.phtml

  <h2>Sign up using this form</h2>  <?php echo $this->tag->form(“signup/register”); ?>  <p>  <label for=”name”>Name</label>  <?php echo $this->tag->textField(“name”); ?>  </p>  <p>  <label for=”email”>E-Mail</label>  <?php echo $this->tag->textField(“email”); ?>  </p>  <p>  <?php echo $this->tag->submitButton(“Register”); ?>  </p>  </form>

Validating Form

Phalcon forms are integrated with the validation component to offer instant validation.

  <?php  use PhalconFormsElementText;  use PhalconValidationValidatorPresenceOf;  use PhalconValidationValidatorStringLength;  $name = new Text(      ‘name’  );  $name->addValidator(      new PresenceOf(          [              ‘message’ => ‘The name is required’,          ]      )  );  $email = new Text(  ’email’  );  $name->addValidator(      new PresenceOf(          [              ‘message’ =>’The email is required’,          ]      )  );  $form->add($name);  $form->add($email);  ?>
