This is a simple PHP model-view-controller (MVC) framework with user authentication.
Download or clone the project:
git clone [email protected]:Tavafi/poler.git
Instructs composer to create autoloader:
composer dump-autoload
Import User.sql into your database:
mysql -u root -p -h localhost YourDataBase < User.sqlAll of the environment variable options are in env.php.example file.
Copy env.php.example to env.php:
cp env.php.example env.phpYou can add additional options to $variables array as you want. Edit DB_ values in order to connecting to database:
'DB_HOST' => 'localhost',
'DB_USERNAME' => 'DBUser',
'DB_PASSWORD' => 'DBPass',
'DB_NAME' => 'DBName',
'DB_PORT' => '3306',Default database host address is localhost. Modify it to another host if you want.
Now you can access variables globally in your code using env() function. For example:
$dbHost = env('DB_HOST');Configure your web server's document / web root to be the public directory. The index.php in this directory serves as the front controller for all HTTP requests entering your application.
The main directory of the application is app with predefined structure.

For example:
<?php
namespace App\models;
use App\core\Model;
class Example extends Model
{
}If your model connects to specific table, modify $table property of the class to its name.
protected $table = "example";There are some predefined validation rules in the base model class that are listed below. You can add additional types as you want.
| Rules | Definition |
|---|---|
| string | Data type is string. Value length <= 255 characters |
| integer | Data type is integer and unsigned |
| text | Data type is string. Value length <= 65535 characters |
| required | Value is not null or empty |
| unique | Value is unique in model's table |
All you need is to define the rules() method in your model class that it has to return an array of rules. Each key of this array specifies the rule name that it contains an array of attributes to be validated.
For example the example class has three attributes, username, password and age:
class Example extends Model
{
protected $table = "example";
public function rules(): array
{
return [
'string' => [
'username',
'password'
],
'required' => [
'username',
'password'
],
'integer' => ['age']
];
}
}Create your own view files under the views/ directory. It is better to have separated directories for each of your controller classes, but there is no compulsion for this. All you have to do is that to create a .php file, e.g. example.php, with specific namespace and all the rest of your front codes.
For example we need a view file for our example class, we create the example.php file under the example directory:
app/views
└── example
└── example.phpIt looks like:
<?php
namespace App\views\example;
?>
All of the front codes must be written here :)Based on Yii 2.0 definition, layouts are a special type of views that represent the common parts of multiple views. For example, the pages for most Web applications share the same page header and footer. While you can repeat the same page header and footer in every view, a better way is to do this once in a layout and embed the rendering result of a content view at an appropriate place in the layout.
Creating layouts is similar to views, but they have to be created under views/layouts/ directory.
For example:
app/views
└── layouts
└── Example.phpIt looks like:
<?php
namespace App\views\layouts;
?>
All of the front codes must be written here :)Create your controller classes in controllers/ directory. You must inherit from \App\core\Controller base class that it contains some useful methods such as redirect() and render().
There are two steps needed to create a controller:
- Choose a name for your class :) e.g.
Example - Concatenate it with
Controllerkeyword
Now we have ExampleController class. It looks like:
<?php
namespace App\controllers;
use App\core\Controller;
class ExampleController extends Controller
{
protected $layout = 'Example';
}As you can see you can specify which layout must be loaded for all methods inside the controller by defining $layout property.
There are two useful methods that you can call in your controllers, redirect() and render():
This method redirects to a specific URL route. All you have to do is that to pass the route as the first argument of this method.
For example in our example class we have an index method that redirects to /home/index:
public function index()
{
$this->redirect('/home/index');
}This method renders a specific view. It accepts two parameters:
- View file name
- Array of data you need in the view
For example in our example class we have a hello method that renders example/hello.php view file with 'Hello World' message:
public function hello()
{
$this->render('example/hello', [
'message' => 'Hello World'
]);
}It will fill the $data variable with the array you have passed to the view. Now you can access to the message just like this:
<?= $data['message'] ?>There are some simple query methods that you have access into your models if your model extends \App\core\Model base class.
This method creates new record with specific data passed as the first argument to this method. For example:
(new \App\models\Example)->create([
'username' => 'AliTavafi',
'password' => 'passwordHash',
'age' => 21
]);This method select all or specific columns from the table. You can pass the array of columns you want as the first argument.
This method returns only one record.
This method returns all records.
For example:
(new \App\models\Example)->select()
->one();
// or specific columns
(new \App\models\Example)->select(['username', 'age'])
->one();Or
(new \App\models\Example)->select()
->all();
// or specific columns
(new \App\models\Example)->select(['username', 'age'])
->all();This method apply conditions to the query. It has three main parameters:
->where(column, operator, value);For example:
(new \App\models\Example)->where('username', '=', 'AliTavafi')
->where('age', '=', 21)
->select()
->one();It will return the first record of the example table with 'AliTavafi' username.
This method updates a record with specific data. It accepts an array of column => value that updates table's column with the value. For example:
(new \App\models\Example)->where('username', '=', 'AliTavafi')
->update([
'username' => 'Tavafi',
'password' => 'newPasswordHash'
]);This methods sorts the query result based on a column and an order type.
Order types:
- ASC (default type that means ascending)
- DESC (descending)
It has two main parameters:
->orderBy(column, 'ASC' or 'DESC');For example:
(new \App\models\Example)->where('age', '>=', 20)
->orderBy('id', 'DESC')
->select()
->all();This method returns only one record with specific condition. It has three main parameters:
->getByColumn(column, value, order type); // Default order type is 'ASC'For example:
(new \App\models\Example)->getByColumn('age', 21, 'DESC');It will sort the records descending and return the first record with age 21.
This method returns all records with specific condition. It has three main parameters:
->getAllByColumn(column, value, order type); // Default order type is 'ASC'For example:
(new \App\models\Example)->getAllByColumn('age', 21, 'DESC');It will sort the records descending and return all records with age 21.
