The called constructor method for WP_Widget is deprecated since version 4.3.0

Question

I just updated to WordPress 4.3 and it seems that something is broken.

I get this error that shows up on my page:

Notice: The called construct

Answer 1

I am also getting the same error And I fixed it in such a way

class Dokan_Category_Widget extends WP_Widget {

    /**
     * Constructor
     *
     * @return void
     **/
    public function __construct() {
        $widget_ops = array( 'classname' => 'dokan-category-menu', 'description' => __( 'Dokan product category menu', 'dokan' ) );
        $this->WP_Widget( 'dokan-category-menu', 'Dokan: Product Category', $widget_ops );
    }
}

As way of calling constructor in such way is deprecated in php 7, so I replaced calling way as $this->WP_Widget() with parent::__construct()

class Dokan_Category_Widget extends WP_Widget {

    /**
     * Constructor
     *
     * @return void
     **/
    public function __construct() {
        $widget_ops = array( 'classname' => 'dokan-category-menu', 'description' => __( 'Dokan product category menu', 'dokan' ) );
        //$this->WP_Widget( 'dokan-category-menu', 'Dokan: Product Category', $widget_ops );
        parent::__construct('dokan-category-menu', 'Dokan: Product Category', $widget_ops  );
    }
}
