THIS IS NOT PACKAGE WITH ALL FORM FIELD CLASSES!
IF YOU JUST WANT TO CREATE A FORM VERY QUICKLY,
USE PACKAGE mvccore/ext-form-all INSTEAD WITH ALL FORM FIELDS AND VALIDATORS!

MvcCore extension with base form and field classes to create and render web forms with HTML5 controls, to handle and validate submited user data, to manage forms sessions for default values, to manage user input errors and to extend and develop custom fields and field groups.

This package can not exist alone without any form field extension(s) like: mvccore/ext-form-field-* to have possiblity to create specific field(s) in youf form instance. If you want to use all fields and validators, use extension mvccore/ext-form-all instead of mvccore/ext-form. This extension is only part of whole thing to not have too much field classes code in small aplications.

Installation

composer require mvccore/ext-form

Than you need install any form field extension bellow like: mvccore/ext-form-field-*

composer require mvccore/ext-form-field-text

All About Features

creates, renders and submits dynamicly created web forms without needs to specify any static model class for form model (like in classic .NET MVC forms)
implemented all HTML5 form attributes, all HTML5 fields and their HTML5 and older atributes
every field has it's build-in default validator and it's possible to define any other or all field validators by you
automatic/customizable CSRF and XSS protection
- every form (GET/POST) has it's own cross site request forgery (CSRF) hidden input with token name and token value to check if form was submitted by specific user session and not by any foreing atacker javascript code
- possiblity to manage CSRF protection by your own
- all field where is possible to pass dangerous characters for XSS attack are protected by validator for XSS safe string by default. It's possible to remove this validator and implement it's own protection
error messages - stored in session only for one form submit, rendered automaticly
templates rendering automaticly or by custom template
- naturaly rendered form has each control in empty div
- rendered custom template shoud have any content and CSRF tokens are creted automaticly by $form->RenderFormBegin();
- any complex form control could have also it's own custom template
- any form or control template has automaticly asigned properties from it's local $this context and original $controller->View from controller passed into form __construct(); is asigned into $this->View.
possibility to extend form itself, any field, field group or validator, you can use build-in interfaces, abstract classes and traits
custom js/css assets for any field type
- possible to render immediately after form HTML body (by default)
- possible to render as external linked file by custom renderer or custom response appending script/solution
- posibility to extend build-in javascripts by checkout and extend: "mvccore/ext-form-js"

- loading default values or previous submit values from session
- possible to optionally clear session after submitting
different/custom result states for multiple submit buttons
- declarating error url, success url (previous and next step url for special developer implementations)

form have build-in language property (for translator) and locale property for advanced fields and validators

Examples

Basic Example

Form Initialization At 'Contact:Default' Route:

$form = (new \MvcCore\Ext\Form($mvcCoreController))
	->SetId('newsletter')
	->SetAction(
		$mvcCoreController->Url('Contact:Submit')
	)
	->SetSuccessUrl(
		$mvcCoreController->Url('Contact:Submitted')
	)
	->SetErrorUrl(
		$mvcCoreController->Url('Contact:Default')
	);
$email = (new \MvcCore\Ext\Form\Email)
	->SetName('mail')
	->SetLabel('Your email:')
	->SetRequired();
$submit = (new \MvcCore\Ext\Form\SubmitButton)
	->SetName('submit')
	->SetValue('Send');
$form->AddFields($email, $submit);
$mvcCoreController->view->newsletterForm = $form;

Form Rendering In Template At 'Contact:Default' Route:

<body>
	<?php echo $this->newsletterForm; ?>
</body>

Form Submitting At 'Contact:Submit' Route:

// ... form initialization again into var: $form 

// process all configured validators by: $form->Submit();
list($result, $data, $errors) = $form->Submit();

// if data has been submitted successfuly, 
// store user email somewhere in database:
if ($result == \MvcCore\Ext\Form::RESULT_SUCCESS) {
	// store user email somewhere by any custom model class (User):
	(new User())->SetEmail($data['mail'])->Save();
	// clear form session space to not display filled 
	// data by current user to another users
	$form->ClearSession();
}

// redirect user to configured success 
// or error url (by internal $form->Result property):
$form->SubmittedRedirect();
