How to fix Smartaddons modules after Virtuemart Update

How to fix Smartaddons modules after Virtuemart Update

Recently we found out that after updating Virtuemart to 3.6 , some SmartAddons modules like 
  • SJ Listing Tabs for VirtueMart
  • SJ Super Category for Virtuemart
  • SJ Categories for VirtueMart
  • SJ Deals for VirtueMart
  • SJ Filter for VirtueMart
  • and ...
have problem in backend setting. In fact in module setting for section [Select Category] you see this error :
Maybe your component (Virtuemart) has been installed incorrectly. Please sure your component work properly. If you still get errors, please contact us via our forum or ticket system
There is no specific solution in smartaddons forum yet but we present a simple way to fix that. All above modules has is a file in path : 
that using a variable with name JPATH_VM_ADMINISTRATOR which is not available in new version of virtuemart. So you need to simply change (near line 46 ):

if (!class_exists('VmModel')) {
                if (defined('JPATH_VM_ADMINISTRATOR') && file_exists(JPATH_VM_ADMINISTRATOR . '/helpers/vmmodel.php')) {
                    require JPATH_VM_ADMINISTRATOR . '/helpers/vmmodel.php';
                } else {
                    $this->error = 'Could not find VmModel helper';
                    return false;
with below codes :
if (!class_exists('VmModel')) {
                if (file_exists(JPATH_ADMINISTRATOR . '/components/com_virtuemart/helpers/vmmodel.php')) {
                    require_once(JPATH_ADMINISTRATOR . '/components/com_virtuemart/helpers/vmmodel.php');
                } else {
                    $this->error = 'Could not find VmModel helper';
                    return false;
 Save the file and refresh module backend. the problem should be fixed!
Add "ajax remove" to J2store minicard module

Add "ajax remove" to J2store minicard module

Minicard is a module in J2store that shows basket products by mouse over. Unlike Virtuemart modules, J2store hasn't an Ajax remove button. In this article we suggest a simple way (in 4 steps) to add it without source hacking.
1) First of all you need to make a copy of J2store minicard module from below path :
to :
Note that [Template] is the name of your template. Also you need to make a folder with name mod_j2store_cart if it doesn't exist in html folder.
2) Open the new file detailcartonhover.php and goto line 84 : 
<a class="cart-remove text-error" href="/<?php echo JRoute::_('index.php?option=com_j2store&view=carts&task=remove&cartitem_id='.$item->cartitem_id); ?>" > <i class="fa fa-remove"></i></a>
and replace it with below codes :
<form onsubmit="removeItemAjax(<?php echo $item->cartitem_id ?>,'<?php echo JUri::base();?>');return false;" >
	<input type="hidden" class="form-control" id="productId-<?php echo $item->cartitem_id ?>" value="<?php echo $item->cartitem_id ?>">
	<div class="deleteLoading" id="deleteLoading-<?php echo $item->cartitem_id ?>">&nbsp;</div>
	<button type="submit" id="deleteButton-<?php echo $item->cartitem_id ?>" ><i class="fa fa-remove"></i></button>
3) Now we need to define removeItemAjax(). So just add below codes to a js file of your template like  [template]\js\custom.js :
//Ajax-remove product from minicard module
function removeItemAjax (id,base){

			$('#deleteLoading-'+id).css("display", "inline-block");
			// process the form
				type        : 'GET', // define the type of HTTP verb we want to use (POST for our form)
				url         : base+'index.php?option=com_j2store&view=carts&task=remove&cartitem_id='+ id, // the url where we want to POST
				success: function(data)
					    $('.cart-item-count').css("background", "yellow");

function doMiniCartErsalo() {
(function($) {		
		var murl = j2storeURL
			+ 'index.php?option=com_j2store&view=carts&task=ajaxmini';

			url : murl,
			type : 'get',
			cache : false,
			contentType : 'application/json; charset=utf-8',
			dataType : 'json',
			success : function(json) {				
				if (json != null && json['response']) {
					$.each(json['response'], function(key, value) {
						if ($('.j2store_cart_module_' + key).length) {
							$('.j2store_cart_module_' + key).each(function() {							

4) And the final step is about CSS loading gif. As previous step add below codes to a css file like [template]\css\custom.css. Check that loading.gif be in [template]\images path.
.deleteLoading {
	background:url('../images/loading.gif') no-repeat;


If you do all these steps correctly, after a complete site refresh (CTRL+F5) you can see new Ajax remove button in J2store minicard. Try a test yourself in live j2store template. Add a product to basket and delete it from minicard dropdown!
