Simple form example.

Simple form exampleContains text and email input elements and demonstrates form processing and validation. In this simple case none of the elements are set required, so an empty form would also be valid.

<?php
/*
* Load the library...
*/
require_once '../../HtmlForm.php';
/*
* Create the example form 'simpleForm'
*/
$form = new Depage\HtmlForm\HtmlForm('simpleForm');
/*
* Add the various input elements to the form by calling the '"add" + element
* type' method.
* The first parameter is the name of the element; it's a unique
* identifier and therefore required. The optional second parameter is an array
* of element settings.
*/
$form->addText('username', [
'label' => 'User name',
'required' => true,
]);
$form->addEmail('email', [
'label' => 'Email address',
]);
/*
* The process method is essential to the functionality of the form. It serves
* various purposes:
* - it validates submitted data if there is any
* - it redirects to the success page if all the data is valid
* - it stores the data in the session and redirects to the form to circumvent
* the form resubmission problem
*/
$form->process();
/*
* Finally, if the form is valid, dump the data (for demonstration). If it's
* not valid (or if it hasn't been submitted yet) display the form.
*/
if ($form->validate()) {
/*
* Success, do something useful with the data and clear the session.
* The getValues method returns an array of the form element values.
*/
echo('<a href="">back</a>');
echo('<pre>');
var_dump($form->getValues());
echo('</pre>');
$form->clearSession();
} else {
/*
* Display the form.
