C’est mon tutoriel préféré à ce sujet:

http://justintadlock.com/archives/2009/05/26/the-complete-guide-to-creating-widgets-in-wordpress-28

Je l’utilise comme base pour tous mes widgets.

Fondamentalement, le widget est un plugin, mais vous étendez la classe WP_Widget. C’est assez simple, il suffit de suivre ce tutoriel.

Bonne chance!

Si vous souhaitez créer un widget. Accédez à votre dossier de plugins et créez un fichier vierge nommé « sample.php » dans le dossier « Sample ».

Copiez le code ci-dessous et collez-le dans le fichier sample.php.

<?php
/*
Plugin Name: Widget
Description: Widget Description
*/

// Creating the widget
// Create a class named as "sample_widget" that is a child class of "WP_Widget".
class sample_widget extends WP_Widget
{
    //Constructor of class
    public function __construct()
    {
        parent::__construct(
        // Id of our widget.
            'sample_widget', 
        // This is the widget name that will be visible to user
            __('Sample Widget'), 
        // Description of our widget
            array(
            'description' => __('Description of our widget.')
        ));
    }

    // Creating widget front-end
    // This is where the action happens
    // Creating function named as "widget", receiving two parameters.
    public function widget($args, $instance)
    {
        /*Getting and assigning our widget title to wordpress hook "widget_title"
        and passing its value to "$title" */
        $title = apply_filters('widget_title', $instance['title']);
        // Area, that is before the widget is diplayed
        echo $args['before_widget'];
        // Checking "$title" is empty or not
        if (!empty($title)) /* If "$title" is not empty, below code will execute.
        $args['before_title'] -> Displaying content before our widget title
        $title -> Display our widget title
        $args['after_title'] -> Displaying content after our widget title */ {
            echo $args['before_title'] . $title . $args['after_title'];
        }

        // Displaying text of our widget
        echo __('Hello, this is our widget text!');
        // Displaying content after our widget
        echo $args['after_widget'];
    }

    // This function naming our widget title
    public function form($instance)
    {
        // If title is already set.
        if (isset($instance['title'])) {
            // $title is getting already assigned title
            $title = $instance['title'];
        }
        // Otherwise our default title will be "Widget title"
        else {
            $title = __('Widget title');
        }

?>
<!-- These are the settings and user interface that an admin will see -->
<p>
<!-- Already set title will be displayed at the top of our widget in admin panel -->
<label for="<?php
        echo $this->get_field_id('title');
?>"><?php
        _e('Title:');
?></label>
<input class="widefat" id="<?php
        echo $this->get_field_id('title');
?>" name="<?php
        echo $this->get_field_name('title');
?>" type="text" value="<?php
        echo esc_attr($title);
?>" />
</p>
<?php
    }

    // This function will replace old title with new title of our widget
    public function update($new_instance, $old_instance)
    {
        $instance          = array();
        $instance['title'] = (!empty($new_instance['title'])) ? strip_tags($new_instance['title']) : '';
        return $instance;
    }
}

// Function to register and load our newly widget
function sample_widget_load()
{
    // Registering our widget named as "sample_widget"
    register_widget('sample_widget');
}
// Calling our newly created function named as "sample_widget_load" to register our widget
add_action('widgets_init', 'sample_widget_load');

?>
