How to declar add_shortcode in wordpress class file. 

Here, we want to display a form with shortcode in out oop stractured plugin class file.

First we crate a plugin form display file like 

=> public/class-display-forms.php

class DisplayForms{
    private $plugin_name;
	private $version;
    public function __construct( $plugin_name, $version ) {

		$this->plugin_name = $plugin_name;
		$this->version = $version;
        add_shortcode( 'online_assesment_forms', array( $this, 'display_online_assesment_forms' ));
	}
    // display the assesment form on homepage
    public function display_online_assesment_forms(){
        ob_start();
        echo 'you html form or code here . which you return with this shortcode..';
        $content = ob_get_contents(); ob_end_clean();
        return $content;
       
    }
    
   
}
 

Now we call this file at out plugin main file. Here we have a plugin main file which name is abcd-plugin-main.php

Add this file using require 

   require_once plugin_dir_path( dirname( __FILE__ ) ) . 'public/class-display-forms.php'; and define this class new DisplayForms( $this->get_plugin_name(), $this->get_version() );
