-- PHP version -- : 5.5.37

-- Error-message(debug-mod must be tuned on) -- : Notice: Trying to get property of non-object in administrator/components/com_hikashop/classes/cart.php on line 317

Hi,

i have a big problem on the site. When i go to there and add to cart, i have to add items 3 times to cart, before they get into for first item.

only error i see when doing debuging is
Notice: Trying to get property of non-object in administrator/components/com_hikashop/classes/cart.php on line 317

i have tried both with our custom template and the default beez20 template, and it does the same.

i have removed all other errors i was seeing on page, so no idea what is causing it.

any suggestions or help on how to fix this problem would be good

Hi,

Please give us the corresponding lines arround the one given in the php error message.
Do you have any cache enabled on your website ?

from line 310

		JRequest::setVar('new_'.$cart_id,$cart->cart_id);
		JPluginHelper::importPlugin( 'hikashop' );
		$dispatcher = JDispatcher::getInstance();
		$do = true;
		$dispatcher->trigger( 'onBeforeCartUpdate', array(&$this, &$cart, &$product_id, &$quantity, &$add, &$type,&$resetCartWhenUpdate,&$force,&$do) );
		if (!$do) return false;
		if(!$app->isAdmin() && $cart->cart_id){
			$app->setUserState(HIKASHOP_COMPONENT.'.'.$cart_id, $this->cart->cart_id);
		}

Hi,

Ecommerce systems are not compatible with cache, so cache must be disabled in Joomla settings, Joomla cache plugin and potentially cache option in template.

Please send us backend and FTP access to your website via our contact form in order to debug that issue direclty on your website. Don't forget to give the url to that topic in the message.

I have sendt you the info on the contact form

you know, that Joomla has flags you can set, that disable cache for one page/module ? so if you just set this info on everything that is dynmic of your parts, cache can be working fine.

And i have several other pages i help with their Joomla sites wiht Hikashop which runs cache on without any problems, so it really not a cache problems also showed by cache being disabled and the problem still persist

Hi,

The cart is correctly updated, but after we press F5 to refresh the whole page.

Without a backend access we can't see your settings, are you using the Ajax functionality to refresh the cart ?
(in Configuration > Main > Advanced settings)
If not, you maybe have a third extension which avoid the page refresh to update the cart informations.

I have resubmitted the backend login information by the contact form.

problem is still not solved

I have been testing alot on this and found out it was a plugin special for this page that does the problem.

the code that gives the error is

$cartClass = hikashop_get('class.cart');
$cart = $cartClass->loadFullCart();

Jerome any idea on this ?

Hi,

Do you now which plugin is causing that issue ? Please give us more details on this.
If you don't know which of them is causing this, please try to disable them one by one.

Hi Xaviar,

yes as i wrote its a custom plugin to prevent items from selected main categories not to be added in cart as same time as from the other main categories.

the code is as following

function onBeforeCartUpdate(&$a, &$cart, $product_id, $quantity, $add, $type,$resetCartWhenUpdate,$force,&$do) {
		if ($cart->cart_id && $quantity > 0) {
            JFactory::getSession()->set('bbhika', "");
			$pluginsClass = hikashop_get('class.plugins');
			$plugin = $pluginsClass->getByName('hikashop','bedrebad');
			$state = false;
			$mainkat = explode(",",$plugin->params['mainkat']);
			$productClass = hikashop_get('class.product');
			$product=$productClass->get($product_id);
			$inkat = $this->maincat($product_id,$mainkat);
			$cartClass = hikashop_get('class.cart');
			$cc = $cartClass->loadFullCart();
			foreach($cc as $aa ) {
				$v_kat = $this->maincat($aa->product_id,$mainkat);
				if ($v_kat !== $inkat) $state = true;
			}
			if ($state) {
				$do = false; //Stop for at ligge varer i kurven
				JFactory::getApplication()->enqueueMessage(JText::_('HIKASHOP_BEDREBAD_ERROR'),'error');
				JFactory::getSession()->set('bbhika', "error");
			}

		}
	}

	function maincat($pid,$parrent) {
		$state = false;
		$database = JFactory::getDBO();
		$database->setQuery('SELECT category_id FROM '.hikashop_table('product_category').' WHERE product_id = '.$pid.'');
		$ret = $database->loadObjectList();
		foreach ($ret as $r) $id[] = $r->category_id;
		foreach ($id as $i)
		do {
			if (in_array($i,$parrent)) {
				$state = true;
				break;
			}
			$database->setQuery('SELECT category_parent_id FROM '.hikashop_table('category').' WHERE category_id = '.$i.'');
			$ret2 = $database->loadObject();
			if (in_array($ret2->category_parent_id,$parrent)) {
				$state = true;
				break;
			}
			$i = $ret2->category_parent_id;
		} while ($ret2->category_parent_id != 0);
		return $state;
	}

$cartClass = hikashop_get('class.cart');
			$cc = $cartClass->loadFullCart();

So Xavier any help you can give me ?

Hello,
Can you give us :
- A temporary FTP access to your website so that we can directly check your code
- Your custom plugin name (file location)
- Step by step instructions of how to reproduce your issue

Through our contact form so that we can directly test and fix it : www.hikashop.com/support/contact-us.html

Thanks.

Hi Mohamed,

information has been send to you.

Hi,

I can see in the plugin that you changed from loadFullCart() function to the get() one, does that solve the issue ?
In frontend when adding a product it is correctly added to the cart, there is just the page to refresh so maybe you will have to disable the option to use ajax on add to cart buttons, or you have some cache enabled.

ps: I was not able to connect to backend, I tried the two passwords (old and new one) and I've been banned

no it doesn't matter if i use the one or the other, gives same problem.

the plugin was disabled, thats why it worked... i have reenabled it and i have removed your ban from the firewall

Hi,

I still have issues to reach the backend:
take.ms/97M1U

But as you said that you reenabled the plugin I tried again and it seems to be working pretty fine.
If you disabled it, please check the backend access in order to help you.

if you just press the button you should get to the control panel without problems... i will look why it gives that error though.

Hi,

When clicking on the button, I get redirected to the login page.
I just tried again, and I can definitively not reach your backend. The password seems to be no more working so autobanned a second time.
