Percentage shipping using Flat rate

Hey guys, trying to setup a percentage based shipping method, based around subTotal values.

I found a thread with the following code :

Code: Select all

$sub_total = $this->cart->getSubtotal();
		if ( $sub_total <= 70 ) {
			$with_percent = 10;
		} else {
			$with_percent = $sub_total * .15;
		}

Code: Select all

'cost'         => $with_percent,
Which ive added to catalog\model\extension\shipping\flat.php but to no avail, its not working....

Any idea where i've gone wrong? I have left my flat rate values in the admin area as default (8.00) and its still showing flat rate as "£8.00" regardless of the subTotal in the cart....

Thanks in advance!

PS > Here is my flat.php file :

Code: Select all

<?php
class ModelExtensionShippingFlat extends Model {
	function getQuote($address) {
		$this->load->language('extension/shipping/flat');

		$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "zone_to_geo_zone WHERE geo_zone_id = '" . (int)$this->config->get('flat_geo_zone_id') . "' AND country_id = '" . (int)$address['country_id'] . "' AND (zone_id = '" . (int)$address['zone_id'] . "' OR zone_id = '0')");

		if (!$this->config->get('flat_geo_zone_id')) {
			$status = true;
		} elseif ($query->num_rows) {
			$status = true;
		} else {
			$status = false;
		}
		
		$sub_total = $this->cart->getSubtotal();
		if ( $sub_total <= 70 ) {
			$with_percent = 10;
		} else {
			$with_percent = $sub_total * .15;
		}

		$method_data = array();

		if ($status) {
			$quote_data = array();

			$quote_data['flat'] = array(
				'code'         => 'flat.flat',
				'title'        => $this->language->get('text_description'),
				'cost'         => $with_percent,
				'tax_class_id' => $this->config->get('flat_tax_class_id'),
				'text'         => $this->currency->format($this->tax->calculate($this->config->get('flat_cost'), $this->config->get('flat_tax_class_id'), $this->config->get('config_tax')), $this->session->data['currency'])
			);

			$method_data = array(
				'code'       => 'flat',
				'title'      => $this->language->get('text_title'),
				'quote'      => $quote_data,
				'sort_order' => $this->config->get('flat_sort_order'),
				'error'      => false
			);
		}

		return $method_data;
	}
}

Ok so, after some more testing, it does appear to work...

BUT, only when i do the following :

- Add item to cart
- Estimate shipping (The pop up shows the cost as "Flat Rate £8.00)
- Apply shipping
- Shipping cost shows as either £10.00 or 15% depending on the subTotal, which is what i want....

How do i get this shipping amount to show on the pop up and checkout?

Many thanks!

Your 'text' array key line would need to be edited in your catalog/model/extension/shipping/flat.php file.

In other words, this would be the portion you'd be looking for:

Code: Select all

$quote_data['flat'] = array(
				'code'         => 'flat.flat',
				'title'        => $this->language->get('text_description'),
				'cost'         => $this->config->get('shipping_flat_cost'),
				'tax_class_id' => $this->config->get('shipping_flat_tax_class_id'),
				'text'         => $this->currency->format($this->tax->calculate($this->config->get('shipping_flat_cost'), $this->config->get('shipping_flat_tax_class_id'), $this->config->get('config_tax')), $this->session->data['currency'])
			);

			$method_data = array(
				'code'       => 'flat',
				'title'      => $this->language->get('text_title'),
				'quote'      => $quote_data,
				'sort_order' => $this->config->get('shipping_flat_sort_order'),
				'error'      => false
			);

These two lines:

Code: Select all

'cost'         => $this->config->get('shipping_flat_cost'),
				'text'         => $this->currency->format($this->tax->calculate($this->config->get('shipping_flat_cost'), $this->config->get('shipping_flat_tax_class_id'), $this->config->get('config_tax')), $this->session->data['currency'])
