Im trying to get the ajax add to cart feature working on my 1.4.9.1 site. I upgraded from 1.4.8 and some things haven't seemed to work properly. Currently when I add a product to the cart, ajax will update the cart and count correctly but the $output as defined in cart.php appears to be executed twice. I get "8 item(s) in cart:8item(s) in cart:" instead of just "8 item(s) in cart:"

The output section of my cart.php looks like this:

Code: Select all

	public function callback() {
		$this->language->load('module/cart');

		$this->load->model('tool/seo_url');
		
		unset($this->session->data['shipping_methods']);
		unset($this->session->data['shipping_method']);
		unset($this->session->data['payment_methods']);
		unset($this->session->data['payment_method']);	
		
		if ($this->request->server['REQUEST_METHOD'] == 'POST') {
			
			if (isset($this->request->post['remove'])) {
	    		$result = explode('_', $this->request->post['remove']);
          		$this->cart->remove(trim($result[1]));
      		} else {
				if (isset($this->request->post['option'])) {
					$option = $this->request->post['option'];
				} else {
					$option = array();	
				}
				
      			$this->cart->add($this->request->post['product_id'], $this->request->post['quantity'], $option);
			}
		}
				
		$output = '';
		
		if ($this->cart->getProducts()) {
		
    		foreach ($this->cart->getProducts() as $product) {
        		
				$output .= '<a href="index.php?route=checkout/cart">' . $this->cart->countProducts() . ' ' . $this->language->get('text_shoppingbag') . '</a>';
				
	            }
			
    		
    		$total = 0;
			$taxes = $this->cart->getTaxes();
			 
			$this->load->model('checkout/extension');
			
			$sort_order = array(); 
			
			$view = HTTP_SERVER . 'index.php?route=checkout/cart';
			$checkout = HTTPS_SERVER . 'index.php?route=checkout/shipping';
			
			$results = $this->model_checkout_extension->getExtensions('total');
			
			foreach ($results as $key => $value) {
				$sort_order[$key] = $this->config->get($value['key'] . '_sort_order');
			}
			
			array_multisort($sort_order, SORT_ASC, $results);
			
			foreach ($results as $result) {
				$this->load->model('total/' . $result['key']);

				$this->{'model_total_' . $result['key']}->getTotal($total_data, $total, $taxes);
			}
			
			$sort_order = array(); 
		  
			foreach ($total_data as $key => $value) {
      			$sort_order[$key] = $value['sort_order'];
    		}

    		array_multisort($sort_order, SORT_ASC, $total_data);
    	    		
          		foreach ($total_data as $total) {
      			
      			   if ($total['title'] != 'Sub-Total:') {
            $output .= '<div class="product_total">' . $total['text'] . '</div>';
        }

      			      		}
      	
		} else {
			$output .= '<div style="text-align: center;">' . $this->language->get('text_empty') . '</div>';
		}
		
		$this->response->setOutput($output, $this->config->get('config_compression'));
	} 	
}
?>

Thank you so much for reading and helping!

A link to your site might help

Always include a link if you are having a store front issue!

It could, for instance, be a template problem, but we can't tell.

i think its something to do with header.tpl, something to do with the following!

$(document).ready(function () {
$('#add_to_cart').removeAttr('onclick');

$('#add_to_cart').click(function () {
$.ajax({
type: 'post',
url: 'index.php?route=module/cart/minicart',
dataType: 'html',
data: $('#product :input'),
success: function (html) {
$('#header_cart .center').html(html);
}
});
});
});

Yes, your theme uses its own minicart in the header. The opencart core uses the cart sidebox to add that as well.
You need to disable the cart sidebox if using the minicart in the header

The issue has to do with JQuery's removeAttr() and "onclick"- this doesn't fire in IE.

In your ajax_add.js file:

Replace $('#add_to_cart').removeAttr('onclick');
With $('#add_to_cart').prop('onclick',false);

This now works in IE (7,8,9), Chrome and Firefox.
