    I was able to display a custom field on the “ADD & EDIT DISCOUNT PAGE” using this codes:

    function site_count_add_field() {
  echo 
  '<tr>
   <th scope="row" valign="top">
   <label for="edd-max-uses">Site Count</label>
   </th>
   <td>
   <input type="text" id="edd-site-count" name="sitecount" value=""  style="width: 40px;"/>
   <p class="description">The amount of free activation in this coupon. Leave blank for 0.</p>
   </td>
   </tr>';
}
add_action('edd_add_discount_form_before_max_uses', 'site_count_add_field');

function site_count_edit_field($discount_id, $discount) {
  echo '
   <tr>
   <th scope="row" valign="top">
   <label for="edd-max-uses">Site Count</label>
   </th>
   <td>
   <input type="text" id="edd-site-count" name="sitecount" value="" style="width: 40px;"/>
   <p class="description">The amount of free activation in this coupon. Leave blank for 0.</p>
   </td>
   </tr>';
}
add_action('edd_edit_discount_form_before_max_uses', 'site_count_edit_field');

    However, it won’t save anything whatever i tried to enter. Anybody know which step should i do next to make it work?

    Hey @mazikeen

    You need the functionality to save the actual data that you are adding.
    For that you can use the edd_post_insert_discount and edd_post_update_discount actions in EDD.

    You can find them in the includes/class-edd-discount.php file. At the start of your saving function you should validate the edd-discount-nonce that is being sent via the $_POST variable.

    Once you validate it and have the data you could do something like:

    
function custom_discount_data( $meta, $discount_id ) {
	$discount = new EDD_Discount( $discount_id );

	if ( ! isset( $_POST['edd-discount-nonce'] ) || ! wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['edd-discount-nonce'] ) ), 'edd_discount_nonce' ) ) {
		return;
	}
	
	if ( isset( $_POST['sitecount'] )  ) {
		$count = intval( $_POST['sitecount'] );
		
		$discount->update_meta( 'your_custom_meta_key_here', $count );
	}

}
add_action( 'edd_post_insert_discount', 'custom_discount_data', 10, 2 );
add_action( 'edd_post_update_discount', 'custom_discount_data', 10, 2 );

    You would need to edit your site_count_edit_field function and retrieve any stored sitecount values and show that in the input field.
    For that you can use the get_meta method from the $discount class:
    $discount->get_meta( ‘your_custom_meta_key_here’, true );

    The code above is untested but it should get you started.
