Installation

install with WP-CLI

You Can Generate new plugin with WP-Trait Structure:

wp trait start

And fill Your Plugin information e.g. slug and namespace:

1/12 [--slug=<slug>]: wp-plugin
2/12 [--namespace=<namespace>]: WP_Plugin
3/12 [--plugin_name=<title>]: plugin-name
4/12 [--plugin_description=<description>]: plugin description
5/12 [--plugin_author=<author>]: Mehrshad Darzi
6/12 [--plugin_author_uri=<url>]: https://profiles.wordpress.org/mehrshaddarzi/
7/12 [--plugin_uri=<url>]: https://github.com/mehrshaddarzi/wp-trait
8/12 [--skip-tests] (Y/n): n
9/12 [--ci=<provider>]: travis

install with Composer

1) First Create a new directory in your WordPress plugins dir e.g. wp-content/plugins/wp-user-mobile.

3) Run This Command in your directory:

composer require mehrshaddarzi/wp-trait

3) Create plugin main file e.g. wp-user-mobile.php and write:

/**
 * Plugin Name:       My Basics Plugin
 * Plugin URI:        https://example.com/plugins/the-basics/
 * Description:       Handle the basics with this plugin.
 * Version:           1.10.3
 * Requires at least: 5.2

 * License URI:       https://www.gnu.org/licenses/gpl-2.0.html
 * Update URI:        https://example.com/my-plugin/
 * Text Domain:       my-basics-plugin
 * Domain Path:       /languages
 */

# Load Package
require_once dirname(__FILE__) . '/vendor/autoload.php';

# Define Main Class
class WP_User_Mobile extends \WPTrait\Plugin
{

    public function __construct($slug, $args = [])
    {
        parent::__construct($slug, $args);
    }

    public function instantiate(){}

    public function register_activation_hook(){}

    public function register_deactivation_hook(){}

    public static function register_uninstall_hook(){}
}

new WP_User_Mobile('wp-user-mobile');

4) You can add PSR-4 namespace in your Composer.json file:

{
    "require": {
        "mehrshaddarzi/wp-trait": "^1.0"
    },
    "autoload": {
        "psr-4": {
            "WP_User_Mobile\\": "src/"
        }
    }
}

Create New Model

Generate Model in Command Line

You Can Create new Model With Custom namespace in WP-CLI:

wp trait make model <class>

For Example:

wp trait make model Option

or

wp trait make model User\Register

Generate New Post-Type Model

wp trait make post-type Order

Generate New Taxonomy Model

wp trait make taxonomy City

Read More Options wp-cli-trait-command Package.

Generate Model manually

1) Add new Admin.php file in src/ dir:

namespace WP_User_Mobile;

use WPTrait\Hook\Notice;
use WPTrait\Model;

class Admin extends Model
{
    use Notice;

    public function __construct($plugin)
    {
        parent::__construct($plugin);
    }

    public function admin_notices()
    {
        $text = __('This Notice is a example from your plugin', $this->plugin->textDomain);
        echo $this->add_alert($text, 'info');
    }

    public function method_name()
    {
        return 'Code is Poetry';
    }
}

2) For Create new instance from this Class add to plugin main file in instantiate method:

public function instantiate()
{
    $this->Admin = new \WP_User_Mobile\Admin($this->plugin);
}

Global Function

You can access to all classes method with global template function by your plugin slug. for example if your plugin slug is wp-user-mobile, you can call method from Admin class:

echo wp_user_mobile()->Admin->method_name();

or use global variables:

gloabl $wp_user_mobile;
echo $wp_user_mobile->Admin->method_name();

This function show Code is Poetry.

How to Change Global variable and function name

You can add global parameters in PHP Main WordPress File:

new WP_User_Mobile('wp-user-mobile', ['global' => 'my_global']);

and Usage:

echo my_global()->Admin->method_name();

Also for disable global function set null.

new WP_User_Mobile('wp-user-mobile', ['global' => null]);

List of arguments when Create new Plugin object:

$default = [
   'main_file' => '',
   'global' => null,
   'prefix' => null,
   'when_load' => ['action' => 'plugins_loaded', 'priority' => 10]
];

Model Properties

WordPress Hooks

You can use $actions and $filters property in all class, for example:

use WPTrait\Model;

class Post extends Model
{
    public $actions = [
        'init' => 'init_check_user',
        'save_post' => ['save_post_view', 10, 3],
        'pre_get_posts' => 'custom_query_action',
        'admin_notices' => [
            ['save_user_address', 12, 1],
            ['disable_plugin_option', 10, 1]
        ]
    ];

    public $filters = [
        'the_content' => 'add_custom_text',
        'show_admin_bar' => '__return_false',
        'rest_enabled' => false,
        'pre_http_request' => ['disable_custom_api', 10, 3]
    ];

    public function add_custom_text($content)
    {
        return $content . 'My Text';
    }

    public function save_post_view($post_ID, $post, $update)
    {
        if (!$update) {
            $this->post($post_ID)->meta->save('views', 1);
        }
    }

    public function disable_custom_api($preempt, $parsed_args, $url) {
        if( strpos($url, 'https://any_domain.com') !==false ){
            return new \WP_Error( 'http_request_block', "This request is not allowed" );
        }
        return $preempt;
    }
}

    }
    return $date;
});

Collections Lists are available under /Collection.

Views Templates

For use template engine in this package, use Views Collection. Create a folder with name templates in your plugin and put your php file, for example:

# ~/wp-content/plugins/{plugin-slug}/templates/students/table.php
<p><?= $title; ?></p>
<table>
<tr>
<td><?php _e('Name'); ?></td>
<td><?php _e('Family'); ?></td>
</tr>
  <?php
    foreach($students as $student) {
  ?>
      <tr>
      <td><?php $student['name']; ?></td>
      <td><?php $student['family']; ?></td>
      </tr>
  <?php
    }
  ?>
</table>

For Load students/table.php files in your Model, use render Method:

$data = [
    'title' => 'Students List',
    'students' => [
        ['name' => 'Mehrshad', 'family' => 'Darzi'],
        ['name' => 'John', 'family' => 'Smith'],
    ]
];

echo $this->view->render('students.table', $data);

Overriding templates via a theme

By default, Users who use your plugin can change plugin templates in your active WordPress theme.

# ~/wp-content/themes/twentyeleven/{plugin-slug}/students/table.php
<div class="text-right bg-black text-white"><?= $title; ?></div>
<?php
  foreach($students as $student) {
?>
  <div class="card">
    <div class="card-body">
      <p><?php $student['name']; ?></p>
      <p><?php $student['family']; ?></p>
    </div>
  </div>
<?php
}
?>

For disable Overriding templates in custom file, set false in render method:

$this->view->render('students.table', $data, [], $canOverride = false);

Set template attribute

There is several Ways for set attribute:

// First Way
$content = $this->view()
  ->attribute('text', $text)
  ->attribute([
      'description' => __('This is the description', $this->plugin->textDomain)
  ])
  ->render('notice');
echo $this->add_alert($content, 'info');

// Second Way
$content = $this->view()->render('notice', [
  'text' => $text
], [
  'text' => __('This is the description', $this->plugin->textDomain)
]);
echo $this->add_alert($content, 'info');

// Third Way
$content = $this->view();
$content->text = $text;
echo $this->add_alert($content('notice'), 'info');

// Property Way
$view = $this->view->render('notice', [
  'text' => $text . ' with property way'
]);
echo $this->add_alert($view, 'info');

Example Create Ajax Request with Trait

use WPTrait\Hook\Ajax;

class Admin extends Model
{
    use Ajax;

    public $ajax = [
        'methods' => ['signup_user']
    ];

    public function admin_ajax_signup_user()
    {
        # Check User is Auth
        if ($this->user->auth()) {
            $this->response->json(['message' => __('You are a user of the site', 'wp-plugin')], 400);
        }

        # Get Input Email
        $email = $this->request->input('email');

        # Create User
        $user_id = $this->user->add([
            'email' => $email,
            'username' => $email
        ]);
        if ($this->error->has($user_id)) {
            $this->response->json(['message' => $this->error->message($user_id)], 400);
        }

        # Return Success
        $this->response->json(['user_id' => $user_id], 200);
    }
}
