Extra field in own manual shiping plugin

-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.4.8
-- PHP version -- : 5.4

Hi,

I’am developing own manual shipping plugin. I want to add a new field (list) inside shipping method that I’m developing. If customer choose my shipping method extra field should appear. Content of that field will be downloaded form api of other services – so it will be dynamic.

So, when customer click on my shipping method, will see a new list field (it will be list of address to shipping, but it will be downloaded by api). Customer selects one address from list. When the order is made, in confirmation email, that value from new field list will appear. In hikashop orders, that information should also be display (but email is more important).

I spend many hours trying to make that plugin, but I don’t know how to:
a) Insert new field in my shipping plugin (in the list of shipping plugins). I try to use onShippingDisplay method but field appear on the top of checkout page. Also when i use that method my, shiping method don’t display at all
b) How to pass value from new list field to email and order information in hikashop admin panel.

Thank for your help.

Thank You but I have my checkout on one page, I don’t use steps. I have added new field using onShippingSave. I don’t know how to add value from that filed to email with notification.
I find, that i have to add in html version:

Adress: {VAR:ADRESS}

$vars['ADRES'] = ??

1. In onShippingSave method build modal window, that’s shows only when my shipping method was selected. That new window will include new form with list of addresses
2. After user selected address from dropdown list, that value well be stored in $_SESSION
3. In html email directly read vale from $_session an write it to email

function onShippingSave(&$cart, &$methods, &$shipping_id, $warehouse_id = NULL){
		print '
			<div id="okonoinpost">
			<h2>Wybierz paczkomat</h2>
				
				<form id="wybierzpczkomatform" method="post">
				<select id="wybranypaczkomatlista" name="wybranypaczkomatlista">
				<option>Packzomat 1</option>
				<option>Packzomat 2</option>
				<option>Packzomat 3</option>
				</select>
				<input type="submit" value="Zapisz" id="zapiszprzycisk"/>
				</form>
				
			</div>';
}

I don't want to use many steps in checkout, I'am using all in one view. Checkout API is working only on multisteps, so It will not work in my one page view?

ok, I make workaround, useing checkout.php file. Everything almost works fine, but I can't chose my shipping plugin in payment plugin when I use restrictions in payment plugin (I don;t see my shipping plugin on dropdown list in restrictions of payment)

I try to use ups plugin, but It still don’t work. I see that $main -> shipping_params->methodsList is empty. What should I do?

Thank You for help

I Add dthis to my shipping plugin:

	var $inpost_methods = array(
		array('key' => '1', 'code'=>'1', 'name' => 'Ground', 'countries' => 'POLAND'),
		array('key' => '2', 'code'=>'2','name' => 'USA')

	);

		var $convertUnit=array(
		'kg' => 'KGS',
		'lb' => 'LBS',
		'cm' => 'CM',
		'in' => 'IN',
		'kg2' => 'kg',
		'lb2' => 'lb',
		'cm2' => 'cm',
		'in2' => 'in',
	);
	

	function shippingMethods(&$main) {
	
	//var_dump($main -> shipping_params->methodsList);
		$methods = array();
		if (!empty($main -> shipping_params -> methodsList)) {
			$main -> shipping_params -> methods = unserialize($main -> shipping_params -> methodsList);
		}
		if (!empty($main -> shipping_params -> methods)) {
			foreach ($main->shipping_params->methods as $key => $value) {
				$selected = null;
				foreach ($this->canpar_methods as $canpar) {
					if ($canpar['name'] == $key)
						$selected = $canpar;
				}
				if ($selected) {
					$methods[$main->shipping_id . '-' . $selected['key']] = $selected['name'];
				}
			}
		}
		return $methods;
	}

Thank You for help, finally I do it differently. If someone, will be interested to integrate InPost services with HikaShop on their web side, you can send me a private message.
