Supposing that you have installed Wolff, it's time to create your first own page.
That's why there are some useful examples below.
Warning: These examples only show how to use the basic components of Wolff, they are NOT supposed to be use as a reference for production code.
This example shows a page (available at localhost/form) with a simple form that inserts data into the database. Here we will use the controller, language, database and view utilites.
The database class will use the credentials available in system/config.php file.
app/languages/english/form.php:
<?php
return [
'name' => 'Name',
'email' => 'Email address',
'password' => 'Password',
'btn_submit' => 'Submit'
];
app/controllers/form.php:
<?php
namespace Controller;
use Wolff\Core\{DB, Language, View};
class Form
{
// Form view
public function index($req, $res)
{
$data['lang'] = Language::get('form');
View::render('form', $data);
}
// Form submit
public function submit($req, $res)
{
$data = $req->body();
$db = new DB();
$db->query("INSERT INTO user (name, email, password)
VALUES (:name, :email, :password)", $data);
echo 'Done';
}
}
app/views/form.wlf:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Wolff form</title>
</head>
<body>
<form action="{{ url('form/submit') }}" method="post">
<input type="text" name="name" placeholder="{{ $lang['name'] }}">
<input type="text" name="email" placeholder="{{ $lang['email'] }}">
<input type="password" name="password" placeholder="{{ $lang['password'] }}">
<button type="submit">{{ $lang['btn_submit'] }}</button>
</form>
</body>
</html>
You can replace the code of the submit method in the controller with the following code, which uses the Wolff validation utility.
app/controllers/form.php:
// Form submit
public function submit($req, $res)
{
$validation = new Validation;
$validation->setData($req->body());
$validation->setFields([
'name' => [
'minlen' => 4,
'type' => 'alpha'
],
'email' => [
'type' => 'email'
],
'password' => [
'minlen' => 8
]
]);
if (!$validation->isValid()) {
echo 'Invalid data';
return;
}
$db = new DB();
$db->query("INSERT INTO user (name, email, password)
VALUES (:name, :email, :password)", $req->body());
echo 'Done';
}
