HTML form manipulation library for slick

README 文档

README

Slick/Form is a package that helps you work with HTML forms. It allows form creation, input validation and filtering and also helps rendering it as HTML in your views. The goal is to create a Form object that can be worked in the different stages of an HTTP request.

This package is compliant with PSR-2 code standards and PSR-4 autoload standards. It also applies the semantic version 2.0.0 specification.

Install

Via Composer

$ composer require slick/form

Usage

One of the greatest features of Slick/Form package is to facilitate the creation and usage of HTML forms. You probably will need forms in your application and you will need to create all the HTML for every input, validate that input in submission process and filter the input before using it.

Slick/Form helps you with that. All you need is to define your form and its validators and filters and you will have HTML rendering, input validation and filter.

Form definition

Lets start with a very simple example: A login form (login-form.yml)

id: login-form
elements:
  username:
    type: text
    label: Username
    validates:
      notEmpty: Username cannot be empty
    filters:
      - text
  password:
    type: password
    label: Password
    validates:
      notEmpty: Password cannot be empty
  remember:
      type: checkbox
      label: Remember me on this computer
      filters:
        - boolean
  buttonGroup:
    type: fieldset
    elements:
      submit:
        type: submit
        value: Sign in
        attributes:
          class: btn btn-primary

In your application controller

use Slick\Form\FormRegistry;

class LoginController
{
    public function login()
    {
        $form = FormRegistry::getForm('login-form.yml');
        return compact('form');
    }
}

Form HTML rendering

And in your view:

<html>
<head>
    <title>Login form</title>
    <link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
    <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
</head>
<body>
    <div class="form-wrapper">
      <?php print $form; ?>
    </div>
</body>

the result should be as follows:

Form submission/validation

Now with our form in place we need to detect if the form was submitted and if its valid:

use Slick\Form\FormRegistry;

class LoginController
{
    public function login()
    {
        $form = FormRegistry::getForm('login-form.yml');
        if ($form->wasSubmitted()) {
            if ($form->isValid()) {
                $data = $form->getValues();  // An associative array with submitted values
                // Do stuff with the values
            } else {
                // data is not valid
            }
        }
        return compact('form');
    }
}

The Form::wasSubmitted() and Form::isValid() methods encapsulate the retrieve of submitted data and the validation process through all input validation chains.

The Form::getValues() will return an associative array with submitted values filtered. For example the $data['remember'] is a Boolean value because it will use the boolean filter as we set in the login-form.yml definitions file.

Testing
