Problem while creating simple plugin

I have created a menu on admin and created a form with only two fields. Now the problem is that i dont know how can i know when when the form whether the form is submitted or not. Also nothing is displayed that shows that settings are saved or like wise…. My plugin code is that:-

<?php
/*
plugin name: my plugin
plugin uri: https://www.example.com
description: This is just testing plugin
version: 1.0
author: junaid rehman
author uri: https://www.example.com
*/
add_action('admin_menu', 'jun_create_text');

if ( 'save' == $_REQUEST['action'] ) {
	add_option("yourname", esc_attr($_REQUEST["yourname"]));
	add_option("fname", esc_attr($_REQUEST["fname"]));
	add_filter('wp_footer', 'jun_footer');
}
function jun_footer($content){
	echo "Your Name is ".get_option("yourname")."<br>";
	echo "Your Father Name is ".get_option("fname")."<br>";
	}
function jun_create_text(){
		add_menu_page( 'My Plugin Settings', 'Plugin Styling',
'manage_options', __FILE__, 'jun_styling_settings' );
}

function jun_styling_settings(){
	?>
   <div class="wrap">
	<?php screen_icon( 'plugins' ); ?>
	<h2>My Plugin</h2>
    <form method="POST" action="">
    <table class="form-table">
    <tr valign="top">
    <th scope="row"><label for="yourname">Your Name</label> </th>
    <td ><input maxlength="45" size="25" name="yourname" value=""/> </td>
    </tr >
    <tr valign="top">
    <th scope="row"><label for="fname">Father Name</label> </th>
    <td ><input maxlength="45" size="25" name="fname" value=""/> </td>
    </tr >
    <tr valign="top">
    <td>
    <input type="submit" name="save" value="Save Options"
    class="button-primary" />
    <input type="submit" name="reset" value="Reset"
    class="button-secondary" />
    </td>
    </tr>
    </table>
    </form>
    </div>

<?php
}
